CROSS-REFERENCE TO RELATED APPLICATION(S) 
     This application claims priority under 35 U.S.C. § 119 to Korean Application No. 10-2017-0027840 filed on Mar. 3, 2017, whose entire disclosure(s) is/are hereby incorporated by reference. 
     BACKGROUND 
     1. Field 
     A bathroom management apparatus which is installed at a bathroom to store various bath and toilet appliances including towels and to remove humidity in the bathroom is disclosed herein. 
     2. Background 
     A bathroom is a place that allows users to wash clothes, wash a face, wash hands, shower, and defecate, for example. Since the bathroom may be the most humid place, mold and bacteria may easily breed which may lead to unpleasant odors in the bathroom. 
     Some bathrooms may dry and deodorize using a ventilation fan. However, since an operation of the ventilation fan is not suitable or it is insufficient to dry the whole bathroom even while the ventilation fan is operated, pollution may occur due to breeding of mold and bacteria. 
     Accordingly, it is important to prevent mold and bacteria from forming in the bathroom by removing moisture from a bottom of the bathroom, and by drying wet bath and toilet appliances such as wet towels. Further, various facilities such as a washstand, a toilet, a mirror, a towel rack, and a toothbrush holder, for example, as well as a storage room for storing various bath and toilet appliances including towels may be installed in the bathroom. Meanwhile, a user may use electronic products such as hair dryers and shavers and apply make up in the bathroom. 
     If a bathroom management apparatus integrating a function of a toothbrush sterilizer, a function of a cosmetics refrigerator, and a charging function of the electronic products based on a function of the storage room and a dry function of the bathroom is developed, the space utility of the bathroom may be increased. Further, if a bathroom management apparatus independently including various function modules including a storage module having a function of the storage room, an air conditioning module having a drying function of the bathroom, a sterilizing module having a function of a toothbrush sterilizer, a refrigerating module having a function of a cosmetics refrigerator, and a charging module having a charging function of the electronic products is developed, the user may select necessary modules from the function modules to include the selected modules in the bath management apparatus. 
     In addition, an installation position of the function module may be freely changed by taking into consideration storage convenience and usability of the user. Since a toilet, a washstand, and a mirror may be installed in different positions in the bathroom according to users, the installation position of the function module may be freely changed according to an environment of the bathroom. 
     The above references are incorporated by reference herein where appropriate for appropriate teachings of additional or alternative details, features and/or technical background.

     The grooves  132  may be formed at bottom sides of the locking rib  131  so that top sides of the side bending tabs  241 B,  242 B, and  243 B may be inserted into the grooves  132 , respectively. The side bending tabs  241 B,  242 B, and  243 B may be inserted into the grooves  132  formed in the locking ribs  131  so that the frame body  210  does not oscillate in rightward and leftward directions when the frame body  210  is installed inside the cabinet  100 . 
     Furthermore, an upper bending part or tab  241 C may be formed at a top end of the upper back bracket  241  to protrude rearward. The stiffness of the upper back bracket  241  may be improved due to the upper bending tab  241 C, the side bending tab  241 B, and the second inclined tab  241 A. 
     Moreover, upper bending parts or tabs  242 C and  243 C may be formed at upper ends of the lower back brackets  242  and  243  to protrude rearward. Lower bending parts or tabs  242 A and  243 A may be formed at bottom ends of the lower back brackets  242  and  243  to protrude rearward. The stiffness of the lower back brackets  242  and  243  may be improved due to the lower bending tabs  242 C and  243 C, the lower bending parts  242 A and  243 A, and the side bending parts  242 B and  243 B. 
     Hereinafter, an operation of coupling decoration members  171 ,  172 , and  173  with the upper panel  110 , the left side panel  130 , and the right side panel  140  will be described with reference to  FIG. 15  and  FIG. 16 .

     It will be understood that when an element or layer is referred to as being “on” another element or layer, the element or layer can be directly on another element or layer or intervening elements or layers. In contrast, when an element is referred to as being “directly on” another element or layer, there are no intervening elements or layers present. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. 
     It will be understood that, although the terms first, second, third, etc., may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another region, layer or section. Thus, a first element, component, region, layer or section could be termed a second element, component, region, layer or section without departing from the teachings of the present invention. 
     Spatially relative terms, such as “lower”, “upper” and the like, may be used herein for ease of description to describe the relationship of one element or feature to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation, in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “lower” relative to other elements or features would then be oriented “upper” relative the other elements or features. Thus, the exemplary term “lower” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. 
     The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
