Abstract
A method of manufacturing a shower foundation is disclosed. A base including a curb portion is formed by injection molding. A waterproof membrane is sprayed over the base. The membrane includes three vertical extensions which are contiguous with a flat portion of the membrane. A backer layer is placed over the waterproof membrane, the backer layer being made of a flexible sheet material. A drain is formed through the base and is sealed with respect to the backer layer and waterproof membrane. A threshold is made by the addition of a lip formed over the curb portion of the base. A method is also disclosed for installing the shower foundation made by the method of manufacturing. The installing method includes the steps of sliding the shower foundation into a space designated for a shower unit, attaching the waterproof membrane of the shower foundation to studs surrounding the space, installing walls of the shower unit on the base, and securing the shower walls to the studs. Tile may then be directly mounted on the shower walls and base.
