Shower Stall
Showers are essentially small rooms with walls made of tile, glass, plastic, or some other waterproof material with a hanging waterproof curtain or a glass door that slides or swings open.  The floor of the “room” may be a single-piece unit made of plastic or fiberglass, or some other waterproof material (i.e. tile) over a pan that is flashed and sealed to prevent water penetration into the surrounding wall framing.

Prefabricated units, like pre-fab tub units, are usually made from fiberglass-reinforced acrylic or fiberglass and come in a wide assortment of colors and styles.  Some come as single-piece units and some require assembly, such as those with three wall panels and a base pan.

It is critical that the base of the shower pan not leak.  Over time, this would lead to rot and deterioration of the sub-flooring and floor framing.
