Shower enclosure system

A shower enclosure comprises a plurality of prefabricated panels that are arranged to at least partially surround a space for bathing. At least one of the panels is a layered structure having a first layer, a second layer, and a third layer. The first layer forms an interior surface of the shower enclosure exposed to the space for bathing. The third layer is arranged between the first layer and the second layer, and is coupled to the first layer and the second layer. The layered structure is a sandwich structured composite comprising the first layer, second layer, and third layer.

BACKGROUND

Installation of custom shower enclosures is typically very labor intensive, especially for larger sizes of showers. For example, in addition to installation of required plumbing, tiled shower enclosures may require fitting and coupling a backer board to the studs or other structure of a home, fitting and coupling a membrane to the backer board, fitting and coupling individual tiles to the backer board and/or membrane, and applying grout between the tiles. Furthermore, with added complexity due to the structure of a home (e.g., structures being out of square, plumb or level), desired functional aspects of the shower enclosure (e.g., seats, shelves, alcoves, lighting, number of water inlets, steam, doors etc.), and desired aesthetics (e.g., the design, material, etc.), comes added labor and cost. Various prefabricated shower enclosures are currently available, which require less installation labor, but offer limited options as to color and aesthetic design, functional features, and size.

SUMMARY

According to an exemplary embodiment, a shower enclosure comprises a plurality of prefabricated panels that are arranged to at least partially surround a space for bathing. At least one of the panels is a layered structure having a first layer, a second layer, and a third layer. The first layer forms an interior surface of the shower enclosure exposed to the space for bathing. The third layer is arranged between the first layer and the second layer, and is coupled to the first layer and the second layer. The layered structure is a sandwich structured composite comprising the first layer, second layer, and third layer.

According to an exemplary embodiment, a shower enclosure comprises a plurality of panels that are arranged to at least partially surround a space for bathing. The plurality of panels includes a first panel and a second panel adjacent to the first panel. The first panel includes a first elongated end member coupled to an end thereof. The second panel includes a second elongated end member coupled to an end thereof. The first end member and the second end member interfit at first sides thereof to couple the first panel to the second panel and a form a joint therebetween.

DETAILED DESCRIPTION

According to various exemplary embodiments described herein, a shower enclosure includes a plurality of prefabricated panels that are configured for easy installation and significant reduction in associated installation labor, while providing greater flexibility in color and aesthetic design, functional features, and size. For example, a user may order a shower enclosure according to conventional sizes (e.g., corresponding to typical shower receptor or bathtub sizes and standard ceiling heights) or custom sizes (e.g., depending on size and layout constraints of the location for the enclosure), desired aesthetics (e.g., material, color, patterns, images, etc.), and functional features (e.g., outlet and control locations, door or access location and type, lighting type and location, venting and/or steam location, and accessories, such as shelves or baskets that may be easily coupled to the panels). The custom ordered shower enclosure is then provided by the manufacturer, for example, as a kit for easy installation. The kit may include pre-manufactured panels (e.g., with proper size, cutouts, pre-installed valves, outlets, and/or lighting, etc.) and may include necessary hardware for installation of the shower enclosure. Furthermore, the panels may be provided in sizes that are small enough to easily transport through a home, yet large enough such that few panels are required (e.g., four panels, one for each side wall and two for a rear wall of the enclosure).

Referring generally toFIGS. 1-3, according to an exemplary embodiment, a bathing or shower enclosure or surround10includes a plurality of panels (e.g., planar members, structures, section, etc.) that may act as walls, a ceiling, and/or a floor of the enclosure10. Each of the panels includes end members (e.g., extrusions, elements, etc.) at one or more (e.g., four) of its ends (e.g., edges) that are configured to interfit (e.g., interlock, engage, couple to, etc.) an end member of an adjacent panel. In this manner, the plurality of panels are configured to couple to each other to cooperatively define the shower enclosure and form the structure thereof. It should be noted that the terms “enclosure” and “surround” include structures or systems that either fully or partially surround a space for bathing.

For example, according to an exemplary embodiment, the shower enclosure10may include a first rear wall100and a second rear wall200that are configured to provide generally coplanar, generally vertical rear surfaces of the shower enclosure10. By providing the rear vertical, interior surface(s) of the shower enclosure with multiple wall panels, greater widths of shower enclosures may be provided (e.g., approximately 60 inches), while utilizing panels that are of sizes (e.g., approximately 30 inches wide) that are easy to handle for installation and transport through a house. A first side panel300and a second side panel400are arranged generally opposite each other, each side panel300,400being adjacent to one of the rear wall panels100,200and providing a generally vertical side surface of the shower enclosure10, which is generally perpendicular to its adjacent rear panel. A ceiling panel500and/or floor panel600may also be provided, which provide generally horizontal surfaces that are generally perpendicular to each of the wall panels100,200,300,400, or the wall panels may be configured for use with a shower receptor, bathtub, or other lower structure and/or with conventional ceilings or other upper structure. According to other exemplary embodiments, the panels may be configured in other manners including, for example, use of more or fewer panels for each surface and providing panels at different relative angles to each other.

As used herein, the directional terms of forward, rearward, inward, outward, etc. and variations thereof, are generally made in reference to an interior of the shower enclosure10(i.e., forward/inward being toward the interior and rearward/outward being away from the interior) or with reference to an entry of the shower (i.e., forward/outward being in a direction prior to the entry or of exiting the shower enclosure, and rearward being in a direction after entry or of entry into the shower enclosure). Alternatively, the directional terms inner, outer, and variations thereof may be used with reference to a particular component thereof (e.g., outer portions may be disposed outward of inner portions of a particular a component).

Referring generally toFIG. 4, according to an exemplary embodiment, one or more of the panels100(and/or200,300, etc.) is a layered structure (e.g., sandwich structured composite) having a first (e.g., outer) layer110, a second outer layer120, and a third or inner (e.g., core) layer130. The third layer130is arranged between and is coupled to the first layer110and the second layer120to provide the panel100with bending rigidity (i.e., similar to an I-beam). The first outer layer110is exposed to a bather to form an interior (e.g., forward) surface of the shower enclosure10) and is configured for water shedding (e.g., material characteristics, surface finish, etc.). For example, the first layer110may be formed from a relatively thin, generally rigid or stiff material such as glass, acrylic, metal, wood, resin, or any other suitable material with or without decorative features (e.g., etching, back painting, coloring, printed or embedded images, etc.). The second outer layer120generally is not exposed to the bather or water and, therefore, may be configured without aesthetic or water shedding properties. For example, the second layer120may be a relatively thin, generally rigid or stiff material, such as glass, acrylic, metal, resin, wood, or any other suitable material. The third or core layer130is positioned behind the first outer layer so as not to be exposed to the bather or water and, therefore, may not have aesthetically or water shedding properties. For example, the third or core layer may be a relatively thick material (compared to layers110,120) and may be formed of a foam, wood, honeycomb polymer or metal, or any other suitable material. In embodiments where transparent or translucent materials are used for the first layer110, the third layer130may be configured with desirable aesthetic characteristics. According to other exemplary embodiments, the layered structure of each panel may be configured in other manners including, but not limited to, a different number of layers (e.g., more layers), different materials or combinations of materials, etc. Advantageously, by utilizing a sandwich structured composite, each panel may be premanufactured (i.e., manufactured prior to installation, as opposed to in place formation, such as tiling) with a rigid and relatively light weight structure (e.g., due to the layered configuration) for easy movement, placement, and installation within a home.

According to an exemplary embodiment, each panel100includes an elongated end member (e.g.,140,240,340, etc.) at one or more edges (e.g., ends, sides, etc.) thereof. Generally speaking, each end member includes a first end (e.g., side, region, portion, etc.), such as first end140a, configured to be coupled the panel100(i.e., to each of the layers110,120,130) and an end (e.g., side, region, portion, etc.), such as second end140b, that is configured to interfit with an end member of an adjacent panel or another structure. Advantageously, by providing interfitting end members as described herein, a shower enclosure10may be quickly assembled into a generally rigid structure without the use of conventional fasteners to couple wall panels to each other.

It should be noted that, for each end member variation (e.g.,140,240,340, etc.), like reference numerals in the hundreds are generally used to refer to similar features based on function and/or structure (e.g., first ends140a,240a,340aof end members140,240,340, respectively, are configured to couple to the layers of respective panels).

According to an exemplary embodiment, each end member (e.g.,140,240, etc.) may be an extruded aluminum component. According to other exemplary embodiments, each end member may be made according to other methods (e.g., molding, injection molding, etc.), different materials (e.g., alloys, plastics, resins, etc.), and the like.

According to an exemplary embodiment, the first end140aof each member140includes a first segment141(e.g., flange, extension, portion, etc.) and a second segment142(e.g., flange, extension, portion, etc.) spaced apart from the first segment141to define a space143therebetween. For example, a third segment144may extend between the first segment141and the second segment142(i.e., being generally opposed or perpendicular thereto), such that the first, second, and third segments141,142,144generally form a “U” shape. The first outer layer110overlaps (e.g., covers, extends over or in front of, has an adjacent or abutting face with, etc.) the first segment141, so as to generally cover the segment141from view. The first outer layer110may also be coupled directly to an outer surface of the first segment141, such as with an adhesive or other suitable method (e.g., curing thereto, etc.). The second outer layer120may overlap the second segment142(or abut an end of the segment) and may also be coupled directly to an outer surface or end second segment142, such as with an adhesive or other suitable method (e.g., curing thereto, etc.). The third layer or core130is arranged between the first outer layer110and second outer layer120, as well as the space143between the first segment141and second segment142of the end member140. The third layer130may be coupled to the first layer110and second layer120and/or the end member140for example with adhesives or other suitable method (e.g., curing thereto).

According to an exemplary embodiment, a pair of end members is configured to provide a joint (e.g., seam, connection, interface, coupling, etc.) between two adjacent panels. For example, as discussed in further detail below, end member pairs may form an intermediate joint between adjacent, generally coplanar, vertical wall panels, may form a corner joint between adjacent, angularly arranged (e.g., generally perpendicular), vertical wall panels, and may form corner joints between generally horizontal panels (e.g., ceiling, floor) and generally vertical wall panels.

Referring generally toFIGS. 4-12, according to an exemplary embodiment, the second end140bof each end member140opposite the first end140ais configured to couple the end member140to an adjacent panel or other structure. Depending on the location and type of joint, the second end140bof each adjacent panel has a different configuration. Generally speaking, at their second ends (e.g.,140b), each end member (e.g.,140), includes a male member (e.g.,145) and female receptacle (e.g.,146), the male member (e.g.,145) being configured to be inserted or received by a complementary female receptacle (e.g.,246) of an adjacent end member (e.g.,240) and the female receptacle (e.g.,146) being configured to receive a male member (e.g.,245) of the adjacent end member (e.g.,240). More particularly, each pair of interfitting end members includes a forward end member (e.g.,140) having a rearwardly extending segment (e.g.,145) and a rearwardly open recess (e.g.,146) and includes a rearward end member (e.g.,240) having a forwardly extending segment (e.g.,245) configured to be inserted into the rearwardly open recess (e.g.,146) of the forward end member (e.g.,140) and a forwardly open recess (e.g.,246) configured to receive the rearwardly extending segment (e.g.,145) of the forward end member (e.g.,140).

Referring toFIGS. 4-6, according to an exemplary embodiment, end members140,240are configured to couple adjacent rear, generally coplanar, generally vertical wall panels100,200to each other. For example, a first rear wall panel100includes a forward intermediate end member140at a generally vertical edge thereof to be positioned at in an intermediate region of the rear wall. The second rear wall panel200includes a rearward intermediate end member240at a generally vertical edge thereof to be positioned at an intermediate region of the rear wall. The first ends140a,240aof the forward and rearward intermediate end members140,240are configured to couple to the panels100,200(e.g., layers), as described previously. The second ends140b,240bof the end members140,240are configured to interfit (e.g., interlock, engage, couple, etc.) with each other to form a joint (e.g., seam, coupling, connection, interface, etc.) therebetween, such that the panels100,200are substantially coplanar.

According to an exemplary embodiment, the forward intermediate end member140, at its second end140b, includes a rearwardly projecting segment145(e.g., male member, protrusion, extension, portion, etc.) that extends substantially perpendicular from the first segment141. The rearwardly projecting segment145is spaced apart from the third flange144, which also extends substantially perpendicular from the first flange141, so as to define a rearwardly open female receptacle146therebetween.

The rearward intermediate end member240, at its second end240b, includes a forwardly projecting segment245(e.g., male member, protrusion, extension, portion, etc.) that extends substantially perpendicular relative to the first segment241. The forwardly projecting segment245is spaced apart laterally from the third segment244, such that a forwardly open female receptacle or recess246is defined therebetween. The forwardly projecting segment245is generally parallel with at least a portion of the third segment244.

Additionally, the respective widths of the segments or male members145,245and corresponding recesses246,146, respectively of the other end member, may also be cooperatively configured for tight interfitting or engagement therebetween (i.e., the recesses146,246are slightly larger, generally the same size, or slightly smaller than the corresponding male members245,145, respectively, and are configured to deform (e.g., bend, stretch, elastically or otherwise) to receive at least a portion of the corresponding male member therein). Furthermore, the respective lengths of the male members145,245and depths of the corresponding recesses246,146, respectively, may also be cooperatively configured such that the first segments141,241(or first outer layers110,210) are generally coplanar with each other, for example, by having an end of the forwardly extending segment245engage a rear facing surface of the rearwardly open recess146and/or by having an end of the rearwardly extending segment145engage a forward facing surface of the forwardly open recess246.

Configured in these manners, the rearwardly open recess146of the forward intermediate end member140is configured to receive the forwardly projecting segment245of the rearward intermediate end member240, and the forwardly open recess247of the rearward intermediate end member240is configured to receive the rearwardly projecting segment146of the forward intermediate end member140, so as to couple the first rear panel100to the second rear panel200.

According to an exemplary embodiment, as best shown inFIG. 4, the forward intermediate end member140and rearward intermediate end member240are configured to define a space or gap50therebetween, such as to receive a compliant member20(e.g., gasket, seal, etc.) therebetween. For example, forward intermediate end member140may include a rearwardly projecting segment145that is generally L-shaped, having a first leg145a(e.g., portion, extension, etc.) extending substantially perpendicular rearward from the first segment141and a second leg145b(e.g., extension, portion, etc.) extending substantially perpendicular from the first leg145a(i.e., substantially parallel to the first segment141, or a portion thereof). The rearward intermediate end member240may include a forwardly projecting segment245having a first leg245a(e.g., portion, extension, etc.) that extends substantially perpendicular from the third segment244(i.e., substantially parallel with the first segment241, or a portion thereof) and a second leg245bthat extends substantially perpendicular forward from the first leg245b(e.g., substantially parallel with the third segment244, or a portion thereof). The widths of the second leg145bof the rearwardly projecting member145(of the forward intermediate end member140) and the width of the forwardly open recess246of the rearward intermediate end member240are configured such that the second leg145bextends between and/or tightly engages (e.g., being slightly wider, approximately the same length, or slightly shorter) opposing faces of the segment244and second leg245bor a portion thereof (e.g., step or ledge245c). Configured in this manner, the gap50has a width approximately equal to the length of the second leg145bof the forward intermediate end member140less the thickness of the first leg145a.

Furthermore, with a portion of the rearwardly extending segment145of the forward intermediate end member140engaging surfaces of the segment244and second leg245bof the rearward intermediate end member240, the intermediate end members140,240cooperatively engage each other to prevent movement (e.g., translation, pivoting, bending, etc.) between each other and the panels100,200to which they are coupled. Still further, the forwardly projecting segment245and/or rearwardly projecting segment145may be arranged at least in part rearward of the second segments142,242of the respective end members140,240, for example, to increase torsional rigidity of the connection formed between the corner end members140,240.

According to an exemplary embodiment, the end members140,240may each include a channel147,247configured to receive a projection21(e.g., projection, flange, etc.) of the gasket20, so as to retain the gasket20at least partially in the gap50between the forward and rearward intermediate end members140,240. The gasket20functions to prevent water from entering the gap and/or to prevent movement (e.g., translation, pivoting, bending, etc.) between panels100,200and the forward and rearward intermediate end members140,240. The gasket20may also include surfaces that are configured to tightly press or seal against outer surfaces of the first layers110,210of the wall panels100,200, respectively. According to other exemplary embodiments, the gasket20may be configured in other manners including, for example, having a different exposed profile (e.g., non-convex, other curvature, flat, etc.), being flush with or recessed relative to the outer layers110,210of the panels100,200, respectively, only engaging edges of the outer layers110,210of the panels100,200as opposed to forward surfaces thereof, etc.

According to another exemplary embodiment, as shown inFIG. 4a, the gasket (e.g., gasket20a) has a concave exterior profile (e.g., to resemble a caulk seal), and/or includes a central hollow portion to, for example, allow the gasket to be elastically compressed inwardly for insertion into the gap50between end members or between an end member and a base member).

According to an exemplary embodiment, the process of assembly or coupling of the first rear panel100to the second rear panel200includes positioning the forward intermediate end member140in front of the rearward intermediate end member240, and moving the panel100rearward such that the rearward projecting segment145is received within the forwardly open recess246and the forward projecting segment245is received within the rearwardly open recess146(e.g., until one or both of the rearward and/or forward projecting segments145,245engage an opposing surface of the complementary recess246,146, respectively, or until the forward surfaces of the panels100,200are generally flush or coplanar). The gasket20is then inserted into the gap50, such that the protrusions21are received in the channels147,247of the forward and rearward intermediate end members140,240respectively.

According to other exemplary embodiments, end members140,240may be configured in other manners to provide a connection between generally coplanar wall panels100,200including, but not limited to, other angular relationships between different segments of the end members (e.g., non-perpendicular), different number of corresponding male members and female receptacles (e.g., one set, three sets, or no sets with only overlapping flanges), and/or use of mechanical fasteners (e.g., clips, tabs, threaded fasteners, etc.) to couple end members to each other and/or to a wall structure (e.g., wall stud).

Referring toFIGS. 7-9, according to an exemplary embodiment, corner end members340,440are configured to couple a rear, generally vertical wall panel100to a side, generally vertical wall panel300at a corner (e.g., ˜90 degree angle between forward surfaces thereof). For example, the first rear wall panel100includes a rearward corner end member340, and the side panel300includes a forward corner end member440. Each of the corner end members340,440include first ends340a,440aconfigured as described above for coupling to the respective layers of the panels. The second ends340b,440bare configured to interfit (e.g., interlock, couple, etc.) with each other to form a joint (e.g., seam, coupling, connection, interface, etc.) therebetween, such that the panels100,300are at approximately a 90 degree angle relative to each other.

According to an exemplary embodiment, the forward corner end member440, at its second end440b, includes a rearwardly projecting segment445(e.g., male member, protrusion, extension, portion, etc.) that extends at an angle (e.g., approximately 45 degrees) rearward of the first segment441. For example, the rearwardly projecting segment445may extend from a third segment444, the third segment444interconnecting the first segment441and second segment442at a spaced apart distance to define the cavity443therebetween. The rearwardly projecting segment445is spaced apart from the third segment444(e.g., generally parallel with a portion thereof), so as to define a rearwardly open female receptacle446therebetween.

According to an exemplary embodiment, the rearward corner end member340, at its second end340b, includes a forwardly projecting segment345(e.g., male member, protrusion, extension, portion, etc.) that extends forward at an angle relative to the relative to the first segment341(e.g., approximately 45 degrees). For example, the forwardly projecting segment345may extend from a third segment344that interconnects the first segment341and second segment342, the third segment344spacing apart the first segment341and second segment342to form a cavity343therebetween for receiving the third layer330of the panel therebetween. The forwardly projecting segment345is spaced apart from the third segment344(e.g., generally parallel with a portion thereof), so as to define a forwardly open female receptacle346therebetween.

Additionally, the respective widths of the segments or male members345,445and corresponding recesses446,346, respectively of the other end member, may also be cooperatively configured for tight interfitting or engagement therebetween (i.e., the recesses346,446are slightly larger, generally the same size, or slightly smaller than the corresponding male members445,345, respectively, and configured to deform (e.g., bend, stretch, elastically or otherwise) to receive at least a portion of the corresponding male member therein). Furthermore, the respective lengths of the male members345,445and depths of the corresponding recesses446,345, respectively, may also be cooperatively configured such that the forwardly extending segment445engages a rear facing surface of the rearwardly open recess346and/or an end of the rearwardly extending segment445engages a forward facing surface of the forwardly open recess346.

Configured in these manners, the rearwardly open recess446of the forward corner end member440is configured to receive the forwardly projecting segment345of the rearward corner end member340, and the forwardly open recess346of the rearward corner end member340is configured to receive the rearwardly projecting segment446of the forward corner end member440, so as to couple the first side panel300to the rear panel100.

According to an exemplary embodiment, the forward corner end member440and rearward corner end member340are configured to define a space or gap50atherebetween, such as to receive a gasket20atherebetween. For example, forward corner end member440may include a rearwardly projecting segment445that is generally L-shaped, having a first leg445a(e.g., portion, extension, etc.), or portion thereof, extending generally rearward at an angle (e.g., approximately 45 degrees) relative to the first segment441and a second leg445b(e.g., extension, portion, etc.), or portion thereof, extending substantially perpendicular from the first leg445a(e.g., extending forward at approximately a 45 degree angle relative to the first segment441). The rearward corner end member340may include a forwardly projecting segment345having a first leg345a(e.g., portion, extension, etc.), or portion thereof, extending generally forward at an angle (e.g., approximately 45 degrees) relative to the first segment341and a second leg345bthat extends substantially perpendicular forward from the first leg345a(e.g., extending forward at approximately 45 degrees relative to another portion of the first segment341). The widths of the second leg445bof the rearwardly projecting member445(of the forward corner end member440) and the width of the forwardly open recess346of the rearward corner end member340are configured such that the second leg445bextends between and/or tightly engages (e.g., being slightly wider, approximately the same length, or slightly shorter) opposing faces of the segment344and second leg345bor a portion thereof (e.g., step of ledge345c). Configured in this manner, the gap50has a width approximately equal to the width of the second leg345bof the forward corner end member340less the thickness of the first leg345a.

Furthermore, with a portion of the rearwardly extending segment445of the forward corner member440engaging surfaces of the segment344and second leg345bof the rearward corner member340, the corner end members340,440cooperatively engage each other to prevent movement (e.g., translation, pivoting, bending, etc.) between each other and the panels100,300, respectively, to which they are coupled. Still further, the forwardly projecting segment345and/or rearwardly projecting segment445may be arranged at least in part rearward of the second segments342,442of the respective end members340,440, for example, to increase torsional rigidity of the connection formed between the corner end members340,440.

According to an exemplary embodiment, the corner end members340,440may each include a channel347,447, respectively, configured to receive a projection21aof the gasket20a, so as to retain the gasket20aat least partially in the gap50abetween the rearward and forward corner end members340,440. The gasket20afunctions to prevent water from entering the gap50and/or to prevent movement (e.g., translation, pivoting, bending, etc.) between the corner end members340,440. The gasket20amay also include surfaces that are configured to tightly press or seal against outer surfaces of the first layers110,310of the wall panels100,300, respectively. According to other exemplary embodiments, the gasket20amay be configured in other manners including, for example, having a different exposed profile (e.g., curved, concave, convex, etc.), being recessed relative to the outer layers310,410of the panels300,400, respectively, only engaging edges of the outer layers310,410as opposed to forward surfaces thereof, etc.

According to an exemplary embodiment, assembly or coupling of the rear panel100to the corner panel300includes positioning the forward corner end member440in front of the rearward corner end member340, and moving the side panel300rearward such that the rearward projecting segment445is received within the forwardly open recess346and the forward projecting segment345is received within the rearwardly open recess446. The compliant member20ais then inserted into the gap50a, such that the protrusions21aare received in the channels347,447of the rearward and forward corner end members340,440respectively.

According to other exemplary embodiments, end members340,440may be configured in other manners to provide a connection between generally perpendicular wall panels100,300including, but not limited to, other angular relationships between different segments of the end members (e.g., greater or less than 45 degrees, or non-perpendicular), different number of corresponding male members and female receptacles (e.g., one set, three sets, or no sets with only overlapping flanges), and/or use of mechanical fasteners (e.g., clips, tabs, threaded fasteners, etc.) to couple end members to each other and/or to a wall structure (e.g., wall stud).

Referring toFIGS. 10-11, according to an exemplary embodiment, end members240,540are configured to couple the wall panels (e.g., rear panel100, rear panel200, or side panel300) to an upper or ceiling panel500(e.g., forming an approximately 90 degree corner therebetween). The upper end member240is configured substantially similar to the rearward intermediate member240to include a first end240acoupled to respective layers of the side or rear panel100and a second end240bconfigured to interfit (e.g., interlock, couple, etc.) with the ceiling end member540.

According to an exemplary embodiment, the ceiling end member540similarly includes a first end540aconfigured to couple to the respective layers of the ceiling panel500, as described previously, and a second end540bconfigured to interfit with the second end240bof the upper end member240.

According to an exemplary embodiment, the second end540bof the ceiling end member540includes a rearwardly projecting segment545(e.g., male member, protrusion, extension, portion, etc.) that extends rearward in a substantially parallel direction relative to the first segment541. For example, the rearwardly projecting segment545may extend from a position slightly below the first segment541. A second rearwardly projecting segment548also extends in a substantially parallel direction relative of the first segment541, for example, from a position slightly above the first segment541, so as to define a rearwardly open receptacle546therebetween (e.g., at approximately the height of the first segment541).

Additionally, the respective widths of the segments or male members245,545and corresponding recesses546,246, respectively of the other end member, may also be cooperatively configured for tight interfitting or engagement therebetween (i.e., the recesses246,546are slightly larger, generally the same size, or slightly smaller than the male members and configured to deform (e.g., bend, stretch, elastically or otherwise) to receive at least a portion of the corresponding male member545,245, respectively of the other end member, therein). Furthermore, the respective lengths of the male members245,545and depths of the corresponding recess546,246may also be cooperatively configured such that the forwardly extending segment245engages a rear facing surface of the rearwardly open recess546and/or an end of the rearwardly extending segment545engages a forward facing surface of the forwardly open recess246.

Configured in these manners, the rearwardly open recess546of the ceiling end member540is configured to receive the forwardly projecting segment245of the upper end member240, and the forwardly open recess246of the upper end member240is configured to receive the rearwardly projecting segment546of the ceiling end member540, so as to couple the wall panel (e.g.,100, etc.) to the ceiling panel500.

According to an exemplary embodiment, the ceiling end member540and upper end member240are configured to define a space or gap50btherebetween, such as to receive a gasket20btherebetween. For example, ceiling end member540may include a rearwardly projecting segment545having a first leg545a(e.g., portion, extension, etc.) extending generally parallel with the first segment541and a second leg545b(e.g., extension, portion, etc.) extending substantially perpendicular from the first leg545a(e.g., generally perpendicular to the first segment541). The widths of the second leg545bof the rearwardly projecting member545(of the ceiling end member540) and the width of the forwardly open recess246of the upper end member240are configured such that the second leg545bextends between and/or tightly engages (e.g., being slightly wider, approximately the same length, or slightly shorter) the third opposing faces of the segment244and second leg245bor a portion thereof (e.g., step or ledge245c). Configured in this manner, the gap50bhas a width approximately equal to the width of the second leg545bof the ceiling end member540less the thickness of the first leg545a.

Furthermore, with a portion of the rearwardly extending segment545of the ceiling end member540engaging surfaces of the segment244and second leg245bof the upper end member240, the upper end member240and ceiling end member540cooperatively engage each other to prevent movement (e.g., translation, pivoting, bending, etc.) between each other and the panels (e.g.,100) to which they are coupled. Still further, the forwardly projecting segment245and/or rearwardly projecting segment545may be arranged at least in part rearward of the second segments242,542of the respective end members240,540, for example, to increase torsional rigidity of the connection formed between the upper and ceiling end members240,540.

According to an exemplary embodiment, the end members240,540may each include a channel247,547configured to receive a projection21b(e.g., projection, flange, etc.) of the gasket20b, so as to retain the gasket20bat least partially in the gap between the ceiling and upper end members540,240. The gasket20bfunctions to prevent water from entering the gap and/or to prevent movement (e.g., translation, pivoting, bending, etc.) between the ceiling and upper end members540,240. The gasket20bmay also include surfaces that are configured to tightly press or seal against outer surfaces of the first layers110,510of the wall panel (e.g.,100) and ceiling panel500, respectively. According to other exemplary embodiments, the gasket20bmay be configured in other manners including, for example, having a different exposed profile (e.g., concave, convex, other curvature, multi-angled, etc.), being flush with or recessed relative to one or more of the outer layers210,510of the panels200,500, respectively, etc.

According to an exemplary embodiment, assembly or coupling of the ceiling panel500occurs after assembling the wall panels (e.g., rear panels100and200, and side panels300) to each other. The ceiling panel500is raised, such that the rearward projecting segment545is at the height of the forwardly open recesses246of the upper end members of the side wall panels for insertion therein. The ceiling panel500is then slid, such that the rearward projecting segments545are slid within and parallel to side walls and transversely (i.e., perpendicular to) the forwardly open recesses246of the upper members240of the rear walls for insertion therein.

According to other exemplary embodiments, end members240,540may be configured in other manners to provide a connection between a wall panel (e.g.,100,200,300, etc.) and ceiling panel500including, but not limited to, other angular relationships between different segments of the end members (e.g., non-perpendicular), different number of corresponding male members and female receptacles (e.g., one set, three sets, or no sets with only overlapping flanges), and/or use of mechanical fasteners (e.g., clips, tabs, threaded fasteners, etc.) to couple end members to each other and/or to a wall structure (e.g., wall stud).

Referring toFIG. 12, according to an exemplary embodiment, end members140,640are configured to couple the wall panels (e.g., rear panel100, rear panel200, or side panel300) to a base (e.g., shower receptor, bathtub, tray, floor, etc.). The lower end member140is configured substantially similar to the forward intermediate rear member140described above to include a first end140acoupled to respective layers of the wall panel (e.g., rear panels100and200, or side panels300,400) and a second end140bconfigured to interfit (e.g., interlock, couple, etc.) with the base member640.

According to an exemplary embodiment, the base member640is configured to couple to a base (e.g., by coupling segment644or a first leg645aof a second segment645with fasteners and/or adhesive to a wall, floor, or other structure). According to another exemplary embodiments, the base member640may include a first side configured with flanges or segments (e.g., as described above) for coupling to a base structure.

According to an exemplary embodiment, the base member640includes a first (e.g., lower) forwardly projecting segment644and a second (e.g., upper) forwardly projecting segment645(e.g., male member, protrusion, extension, portion, etc.) that extends in a substantially parallel direction relative to the first forwardly projecting segment644, so as to define a forwardly open receptacle646therebetween. For example, the second forwardly projecting segment645may include a first leg645aextending generally perpendicularly upward from the first forwardly projecting segment644, and a second leg645bextending generally perpendicularly forward from the first leg645a.

Additionally, the respective widths of the segments or male members145,645and corresponding recesses646,146, respectively of the end member, may also be cooperatively configured for tight interfitting or engagement therebetween (i.e., the recesses146,646are slightly larger, generally the same size, or slightly smaller than the corresponding male members645,145, respectively, and configured to deform (e.g., bend, stretch, elastically or otherwise) to receive at least a portion of the corresponding male member therein). Furthermore, the respective lengths of the male members145,645and depths of the corresponding recess646,146, respectively, may also be cooperatively configured such that an end of the forwardly extending segment645engages a rear facing surface of the rearwardly open recess146and/or an end of the rearwardly extending segment145engages a forward facing surface of the forwardly open recess646.

Configured in these manners, the rearwardly open recess146of the lower end member140is configured to receive the forwardly projecting segment645of the base member640, and the forwardly open recess646of the base member640is configured to receive the rearwardly projecting segment146of the lower end member540, so as to couple the wall panel to the base600.

According to an exemplary embodiment, the base member640and lower end member140are configured to define a space or gap therebetween (as described above), such as to receive a compliant member (e.g., gasket, seal, etc.) therebetween. For example, lower end member140may include a rearwardly projecting segment145that is generally L-shaped having a first leg145a(e.g., portion, extension, etc.) extending generally parallel with the first segment141and a second leg145b(e.g., extension, portion, etc.) extending substantially perpendicular from the first leg145a(e.g., generally perpendicular to the first segment141). The widths of the second leg145bof the lower end member140and first leg645aof the base member640are configured such that the second leg145bengages the lower forwardly projecting segment644and second leg645b, or a portion thereof (e.g., step or ledge645c). Configured in this manner, the gap has a width approximately equal to the width of the second leg145bof the lower end member140.

According to an exemplary embodiment, the lower end member140may include a channel147configured to receive a projection21c(e.g., protrusion, flange, etc.) of the gasket20c, so as to retain the gasket20cat least partially in the gap between the lower end and base members140,640. According to other exemplary embodiments, the base member640may also include a channel to receive a projection21cof the gasket20c. The gasket20cfunctions to prevent water from entering the gap and/or to prevent movement (e.g., translation, pivoting, bending, etc.) between the lower end and base members140,640, as well as between the wall panels (e.g., rear panels100,200and side panel300) and the base600. The gasket20cmay also include a surface that is configured to tightly press or seal against an outer surface of the first layer (e.g.,110) of the wall panel (e.g.,100).

According to an exemplary embodiment, an end or side of the rearwardly projecting segment145of the lower end member140engages one or more portions of the base member640(e.g., first forwardly projecting segment644, or second forwardly projecting segment645) to prevent pivoting or bending between the wall panels and the base600. According to another exemplary embodiment, the second forwardly projecting segment645and/or rearward projecting segment145are arranged at least in part rearward of the second segment142of the lower end member140to increase torsional rigidity of the connection formed between the lower end member140and the base member640.

According to an exemplary embodiment, assembly or coupling of each wall panel requires raising the wall panel such that the rearward projecting segment145is at the height of the forwardly open recesses646of the base member640for insertion therein.

According to other exemplary embodiments, the lower end member140and base member640may be configured in other manners to provide a connection between a wall panel (e.g.,100,200,300, etc.) and base including, but not limited to, other angular relationships between different segments of the end members (e.g., non-perpendicular), different number of corresponding male members and female receptacles (e.g., one set, three sets, or no sets with only overlapping flanges), and/or use of mechanical fasteners (e.g., clips, tabs, threaded fasteners, etc.) to couple end members to each other and/or to a wall structure (e.g., wall stud).

Referring toFIGS. 13, 15, 16, and 17B, according to an exemplary embodiment, a side panel (e.g.,300) includes a terminating end member (e.g.,740) at a vertical edge thereof, which is generally opposite the corner end member thereof. The terminating end member740includes a first end740a, configured as described previously for interconnecting with the panel300(e.g., layers310,320,330) in the manners described previously. At its second end740b, the terminating end member740may be configured to positively couple to a separate structure (e.g., a wall structure of a home) and/or a fixed or stationary panel30.

According to an exemplary embodiment, the terminating end member740, at its second end740b, defines a recess746(e.g., pocket, region, etc.) in which a substrate25is disposed for receiving a threaded fastener60for coupling the terminating end member740to a wall stud2. The recess is generally defined between a first rearwardly extending flange745(e.g., segment, member, etc.), a forward flange744, and a second rearwardly extending flange748that is generally opposite the first rearwardly extending flange745and spaced apart therefrom by the forward flange744.

According to an exemplary embodiment, the first rearwardly extending flange745interconnects the first segment741and742at a spaced apart distance, so as to define the cavity743therebetween (e.g., to receive the third layer330of the panel300therebetween). The rearwardly extending flange743extends generally perpendicular rearward of the first segment741to a position rearward of the second layer320of the panel300.

According to an exemplary embodiment, the forward flange744extends in a direction generally parallel to the first segment741and may be positioned forward therefrom (e.g., a distance less than the thickness of the first layer310of the panel300). The forward flange744further includes one of more apertures744a(e.g., holes, etc.) at varying heights for receiving the threaded fasteners60therein.

According to an exemplary embodiment, the second rearwardly extending flange748extends generally perpendicular rearward from the forward flange744, thereby defining the recess746in which the substrate25is positioned.

According to an exemplary embodiment, the substrate25enables fastening of the terminating end member740(and thereby the panel300) to a structure (e.g., through a drywall1(or tile, paneling, other decorative layer or material, etc.) and into a wall stud2of a home) with a threaded fastener60. The substrate25is coupled to the terminating end member740, for example, through the use of adhesives, fasteners (not shown), and/or a mechanical connection (e.g., compression fit) between the substrate25and the inner surfaces of the recess746.

According to an exemplary embodiment, the terminating end member740is configured to be mounted (i.e., connected, coupled, etc.) to the wall stud2in a substantially vertical (i.e., plumb) orientation toward or away from the wall stud2. For example, the fastener60itself may be specially configured to provided adjustable spacing between the substrate25and the wall stud2(e.g., as shown, having first and second, spaced-apart sets of threads, the first for engaging the wall stud2and the second for engaging the substrate25). Or, more conventional means may be used, such as positioning shims between the substrate25and drywall1and/or wall stud2before fastening with a conventional threaded fastener.

According to an exemplary embodiment, a wall channel760configured to receive a portion of the terminating end member740and/or substrate25therein, for example, for decorative and/or structural purposes. The wall channel760generally includes two forwardly extending, generally parallel flanges761,762that are interconnected by a generally straight, flat rear segment763. For example, after receiving the terminating end member740and substrate25, a first (i.e., forward) of the flanges761is generally positioned adjacent and/or in contact with a forward surface of the substrate25, and a second (i.e., rear) of the flanges762is generally positioned adjacent and/or in contact with the second rearwardly extending flange745of the terminating end member740. Further, the second flange762of the channel760may be received into a recess742a(e.g., pocket) of the terminating end member740, which is defined generally between portions of the second segment742and the first rearwardly extending flange745.

According to an exemplary embodiment, the wall channel760is configured to be coupled to the home (e.g., drywall1and/or wall stud2), for example, between the generally straight, flat segment763and the drywall1and/or wall stud2with adhesives and/or threaded fasteners. The wall channel760may be configured to provide decorative flange (e.g., the first of the forwardly extending flanges761) configured to cover a gap (e.g., a non-uniform or varying gap arising from a non-straight or out-of-plumb home structure) between the substrate25and drywall2. The wall channel760may additionally provide structural rigidity to the terminating end member740, for example, to prevent movement of the wall panel300in a direction generally perpendicular to the fasteners60(e.g., generally parallel with the drywall1).

According to an exemplary embodiment, the terminating end member is configured to receive and/or couple to a fixed (e.g., stationary, non-moveable, etc.) panel30. The fixed panel30may, for example, be a glass (or other translucent, transparent, or decorative material) panel provided at an entry side of the shower enclosure10and having water shedding property and appealing aesthetics.

According to an exemplary embodiment, the terminating end member740receives the fixed panel30in a corner region generally defined by an outer surface of the second rearwardly extending flange748and a second forward flange749that extends from the second rearwardly extending flange748at a generally 90 degree angle (i.e., generally parallel with the first segment741). The fixed panel30is coupled to the terminating end member740, for example, with an adhesive between a rear surface the fixed panel30and the second rearwardly extending flange748and/or an edge (or end) surface of the fixed panel30and the second forward flange749. Further, a stop or clamp member750may couple to the second forward flange749(e.g., with fasteners (now shown) that extend into holes or a channel of the second forward flange749) to tightly hold (e.g., compress) the fixed panel30between the stop member750and the second rearwardly extending flange748.

According to other exemplary embodiments, the terminating end member740may be configured in other manners to provide connection to a structure and/or fixed panel including, but not limited to, other angular relationships between different segments of the end members (e.g., non-perpendicular), or to couple to a hinged door panel. According to an exemplary embodiment, an alternative terminating end member740amay be configured as shown inFIG. 21.

According to an exemplary embodiment, trim pieces may be provided to cover various features (e.g., attachment features) of the terminating end member740for more pleasing aesthetics and/or improved water shedding characteristics. For example, a first (e.g., interior) trim cover770may be configured to cover interior portions (i.e., visible from inside the shower enclosure10, or through the fixed panel30) of the terminating end member740from view, including, for example, the forward flange744and apertures744athereof. The first trim cover770may, for example, be a plate or sheet having a width approximately equal to the forward flange744, such that the trim cover770extends generally between the first layer310of the side panel300and the fixed panel30. The trim cover770may further have a thickness that is complementary to those of the first layer310and the forward flange744, such that the trim cover770is generally flush (e.g., generally coplanar) with a forward surface of the first layer310of the side panel300. The trim cover770may, for example, be configured to couple to the terminating end member740in a hidden manner (e.g., adhesives and/or hidden mechanical fasteners or features, such as a snap-fit arrangement). The first trim cover770may, for example, be made from a material that is opaque (e.g., to hide the terminating end member740and apertures744a) and aesthetically pleasing (e.g., generally matching or complementary to aesthetics of the first layer310of the side panel300).

According to an exemplary embodiment, a second (or exterior) trim cover780is configured to cover exterior portions (i.e., those visible from outside the shower enclosure10) of the terminating end member740from view, including, for example, the second forward flange749, stop member750, and/or substrate25. For example, the second trim cover780may be configured to couple to the stop member750, for example, with a snap fit connection. More particularly, the trim cover780includes a forward portion781that is generally U-shaped with a flat forward surface and includes generally opposed protrusions782,783(e.g., tabs, extensions, etc.) that are configured to be elastically spread apart for receipt into recesses (e.g., indentations, etc.) on opposite sides of the stop member750. The trim cover780may further include a rearwardly projecting protrusion784that is configured to engage a forward surface of the stop member750to tightly hold the stop member750between the protrusion784and one or both of the opposed protrusions782,783. The trim cover780further includes a rearward depending flange785extending from the forward portion781at a generally perpendicular angle and which is configured to engage a forward surface of the channel760and be generally coplanar therewith. Configured in this manner, the forward portion781and rearward portion785of the trim cover780generally cover the second forward flange749and substrate25of the terminating end member740, as well as the stop member750, from view. The trim cover780is, for example, an extruded aluminum material, or may be made according to other manufacturing methods (e.g., injection molded, etc.) and/or other materials (e.g., other metals, polymers, resins, etc.) as may be aesthetically desirable (e.g., to match the exposed surface of channel760).

According to another exemplary embodiment, as shown inFIG. 19, a trim cover790may be used instead of trim cover780and includes a forward portion791that is generally U-shaped with an angled forward surface. The trim cover790further includes protrusions792,793,794that are configured to engage the stop member750(in similar manner to the protrusions782,783,784of trim cover780). The trim cover790further includes a rearward depending flange795extending from the forward portion791at a non-normal angle and is configured to engage a forward surface of the channel760at a non-normal angle.

According to other exemplary embodiments, drywall1, other paneling, or surface (e.g., tile, etc.) of the home or structure may cover and/or be installed after channel760. In such instances, an alternative trim cover780a(as shown inFIG. 17a) may be utilized. The trim cover780ais configured substantially similar to trim cover780but omits the rearward depending flange785. Instead, the drywall1, or other surface, abuts an outer surface of a leg786aof the trim cover780a.

According to an exemplary embodiment, one or more terminating end members740, or portions thereof, may not receive or be coupled to a fixed panel30. For example, a first side panel300may include a terminating end member740that is coupled to a fixed panel30, while a second side panel400, that is disposed generally opposite the first side panel300, includes a similarly configured end member740but which is not coupled to a fixed panel30. Or, for example, a fixed panel30may extend only part way up the height of the terminating end member740. In such instances, modified versions of the previously discussed trim pieces may be provided and/or additional trim pieces may be provided to cover and/or fill the recess into which the fixed panel30might otherwise be positioned. For example, a wider trim piece760may be configured to extend generally between the trim piece780(or alternatives) and a first layer310of the panel300. Alternative trim pieces780,780a, or790may be configured to extend further past the stop member750so as to cover the void. Further, an additional trim piece (e.g., square, rectangular, or flat or U-shaped profile) may be provided to fill the void.

Referring toFIGS. 14 and 18, according to an exemplary embodiment, the ceiling panel500further includes a forward ceiling end member840. The forward ceiling end member840includes a first side840athat is configured to couple to the ceiling panel500as described previously. At its second side840b, the forward ceiling end member840is configured to couple to the fixed panel30and/or operably couple to a movable panel or door70.

According to an exemplary, at its second side840b, the forward ceiling end member840includes a generally G-shaped cavity846that is defined generally by a rear (e.g., upwardly extending) flange845(e.g., segment, member, etc.), an upper (e.g., outwardly extending) flange847(e.g., segment, member, etc.), a forward (e.g., downwardly extending) flange847, and a lower (e.g., inwardly extending) flange844. The rear flange845interconnects the first segment841and842of the end member840at a spaced apart distance, so as to define the cavity843therebetween (e.g., to receive the third layer530of the ceiling panel500therebetween). The upper flange847extends forward from the rear flange845at a generally perpendicular angle, the forward flange847extends downward from the upper flange847at a generally perpendicular angle, and the lower flange845extends inward from the forward flange847at a generally perpendicular angle at a height generally opposite the bottom end of the upwardly extending flange845. The lower flange844is spaced apart from the rear flange845to define a gap844a(e.g., space) therebetween, for example, for the movable panel70to slide therein.

According to an exemplary embodiment, the forward ceiling end member840is configured to couple to a structure (e.g., drywall, paneling, or decorative structural surface1and/or ceiling joist2). The upper flange847may include apertures847athat are configured to receive a fastener60, therein, a head of which engages a surface (e.g., lower) of the upper flange847. According to other exemplary embodiments, a substrate (e.g., similar to substrate25) may be coupled to an upper surface of the upper flange847(e.g., with adhesives and/or mechanical fasteners), which is then coupled to the structure (e.g., ceiling joist2) with the threaded fastener60. The threaded fastener60may be configured to adjust for level (e.g., similar to the fastener60described above as adjusting for plumb), or conventional means may be used, such as shims described above.

According to an exemplary embodiment, a ceiling channel760, configured similarly to the wall channel described above, may also be provided. For example, the ceiling channel760is configured to provide improved aesthetics and/or additional structural rigidity to the shower enclosure10. The ceiling channel includes generally parallel flanges761,762that are spaced apart by a generally straight, flat interconnecting flange763. The parallel flanges are configured to receive a portion of the forwarding ceiling end member840therein and, in particular, are configured to engage or be adjacent to upper portions of a rear surface of the rear flange845and a forward surface of the forward flange848. The forward flange61is thereby configured to cover a uneven gap between the drywall1and end member840, which may arise due to a non-straight or unlevel ceiling (e.g., drywall1).

According to an exemplary embodiment, the forward ceiling end member840is configured to couple to the fixed panel30in substantially the same manner as the terminating end member740(e.g., through use of a adhesives, stop member750, and trim cover780,780a,790) along an upper edge or end of the fixed panel30. Similarly, for ceiling end members840, or portions thereof, where a fixed panel30is not positioned, alternative formations of trim pieces780,780a, and790and/or additional trim pieces (as for the terminating end member740) may be provided to cover and/or fill the void where the fixed panel30might otherwise be positioned, for example, by extending to and/or covering flange845.

According to an exemplary embodiment, the forward ceiling end member840is further configured to operably couple to a moveable (e.g., sliding) panel70. For example, the lower flange845defines a channel845b(e.g., recess, etc.) configured to receive a slider71(e.g., roller, wheel, etc.) of the movable panel70therein. The gap845ais configured sufficient width to receive the slider71and connecting member72(which connects the slider71to the movable panel70) therein, such that the slider71may lifted into the cavity846and placed into the channel845b. Furthermore, the height of the cavity846is also configured to provide sufficient clearance for the slider71to be received therein (e.g., vertical clearance to be moved laterally over a lip of the channel845bto be placed therein) and move therein (e.g., slide, roll, etc.) after placement. Configured in this manner, the forward ceiling end member840provides support for the movable panel70to be positioned in and slide within a plane that is generally parallel with the fixed panel30and/or generally perpendicular to side panel300and/or side panel400. According to an exemplary embodiment, the movable panel70may comprise a glass material, or any other material with suitable water shedding and appealing aesthetics (e.g., the same material as fixed panel30, or otherwise complementary to interior panels100,200, etc.).

According to other exemplary embodiments, the forward ceiling end member may be configured in other manners including, for example, for sealing with a hinged door or as the alternative forward ceiling end member840ashown inFIG. 22.

According to an exemplary embodiment, a terminating end member and/or forward ceiling end member may be configured to mount or couple to a structure (e.g., wall stud2or ceiling joist2) in another manner. Referring toFIG. 20, for example, an end member940may include a first end940aconfigured to couple to a wall or ceiling panel (e.g., respective layers thereof) as described previously. At its second end, the end member940is configured to couple to a fixed panel as described previously (e.g., with flanges948,949configured similar to flanges748,848and749,849, respectively of end members740and840, with stop member750, and or trim covers780,780a, etc.). However, instead of being coupled directly to a structure (e.g., wall stud2or joist2) directly with a fastener60or indirectly with a substrate25and fastener60, a generally L-shaped member or extrusion962is coupled at a first flange directly to the structure with a fastener61(e.g., nail, screw, etc.). At a second flange, depending generally perpendicular to the first flange, the member962is coupled to a rearward depending flange945of the end member940with a fastener62(e.g., screw), which may be moved relative to the member962(e.g., through elongated aperture) and/or end member940so as to adjust for plumb or level. The L-shaped member962may further include a lip disposed generally opposite the second flange that is configured to receive a flange of a generally L-shaped trim cover961thereunder (e.g., elastically to be pressed between drywall, tile, stud or other structure and the lip of the L-shaped member962), a second flange of which depends generally perpendicular therefrom to cover an gap between the forward flange949of the end member940and the structure. A trim cover780may engage the second flange of the trim cover961.

According to an exemplary embodiment, the panels (e.g.,100to500) and/or end members (e.g.,100to600) may be configured in various additional manners including, for example, to mount accessories and to aid and/or provide greater flexibility in plumbing installation. For example, the corner end members300,400and/or intermediate end members100,200may be configured to mount accessories (e.g., baskets, shelves, hooks, grab bars, etc.) thereon. For example, each accessory may include male members that are configured to be inserted into the gaps (e.g.,50) formed between the respective members (i.e., where a gasket (e.g.,20) might otherwise be positioned). The male members may be configured to positively engage the recesses (e.g.,147,247, etc.), tightly fit between end members, or otherwise be configured for coupling (e.g., releasably coupling, without fasteners) to the end members. For example, a vertical grab or accessory bar may be coupled to an intermediate or corner joint, so as to at least partially obscure a user's view of the joint and provide a structure to which accessories may be mounted (i.e., being indirectly mounted to the end members).

For example, as shown inFIGS. 23-23B, an accessory may be mounted or otherwise coupled to the enclosure using a mounting980(e.g., mounting member, anchor, etc.). The mounting980includes an elongated portion981having a cylindrical or other cross-sectional profile having dimensions (e.g., diameter) allowing it to be inserted into the gap50between the corner end members300,400(or other end members as described above). Flanges982(e.g., wings, protrusions) extend outward from the elongated portion981in opposite directions and are configured to be inserted into the channels (e.g.,347,447) of the end members300,400in which a protrusions of a gasket (e.g.,20) might otherwise be positioned. The flanges982have a width (i.e., measured perpendicular to both the axial and radial direction of the elongated portion981) that allows the mounting980to be inserted into the gap50, and may also have a rounded, or tapered profile, that allows the mounting to be rotated for the flanges982to be positioned (e.g., by sliding) into the channels of the end members300,400. The thickness of the flanges982may be configured to tightly interfit the channels of the end members300,400in an axial direction (i.e., relative to the elongated portion981). A distance between the ends of the flanges982may be configured relative to a distance between the channels of the two end members300,400, so as to press against the end members300,400as the mounting980is twisted into position with the flanges982in the channels of the end members. In these manners, the mounting980may be tightly coupled or secured to the end members300,400without forming any holes in the members, panels, or other components of the enclosure that might otherwise provide a way for water to escape the enclosure. Further, in these manners, the mounting980may also provide for a tighter or otherwise improved connection between end members (e.g., the mounting980functioning similar to a set screw between the two end members). To rotate the mounting980into position, the mounting980may include a hexagonal female recess (not shown) axially aligned with the elongated portion981that is configured to receive an Allen wrench. The mounting980may also include a widened head or end (external outside of the gap50), which may, for example, be received within a channel of an accessory for coupling the accessory to the mounting980. Instead, or additionally, the mounting980may be configured to receive a threaded or other type of elongated fastener983therein (e.g., axially aligned with the elongated portion981), which may be used to couple an accessory thereto.

According to an exemplary embodiment, the wall panels (e.g.,100to400) are configured to provide smaller rough-in openings than are conventionally required (e.g., to provide reduced escutcheon size for covering such openings) and/or may have rough-in valves and/or supplies mounted directly to the wall panel (e.g., during manufacturing to provide simplified on-site installation.

According to still further exemplary embodiments, the shower enclosure may include additional features including, for example, lighting that may be incorporated into the ceiling panel500or other panels, niches that may include a cutout into one of the wall panels, and/or generally an entirely closeable or sealable structure for a steam shower.
