Claim:
A shower receptor installation assembly for a subfloor with a drain, the assembly comprising: (a) a resilient dense foam underlayment having a perimeter, a drain opening, and an upwardly extending shoulder along part of its perimeter forming an entrance to the shower; (b) a rigid plastic base conformed to fit onto the underlayment, the base having a perimeter, a drain opening, an upwardly extending shoulder along part of its perimeter forming an entrance to the shower, a floor with an upper surface that slopes toward the drain opening, and side walls along all the perimeter except for the part containing the upwardly extending shoulder; (c) a mesh member attached to the upper surface of the floor of the base with adhesive, the mesh member being adapted to adhere to grout; (d) a plurality of screed blocks resting upon the mesh member, each screed block having a top surface and a bottom surface, the distance between the top surface and the bottom surface defining the height of a screed block; and (e) a plurality of strike rails, each strike rail having two sides, a top edge, and a bottom edge, the distance between the top edge and bottom edge defining the height of a strike rail; each strike rail being attached at its bottom surface to the top surface of two or more screed blocks with removable adhesive; the strike rails and screed blocks being adapted for use in applying a bed of grout to the floor of the base that has the same slope as the floor and that has a depth equal to the height of a strike rail plus the height of a screed block.
