Prefabricated bathroom walls

摘要

A prefabricated polymer bathroom wall apparatus has a unitary molded wall section formed of a waterproof polymer and having a gridwork of interconnected molded frame portions forming a plurality of hollow cells therebetween and having a plurality of edges with one or more insets in the edges. Some of the molded frame portions are formed with elongated passageways therein to form prefabricated pipes in the wall section opening at the wall insets. Coupling members are attached to the ends of the passageways within the wall section edge insets whereby a lightweight prefabricated wall section can be attached to a wall for coupling to a building's plumbing and to plumbing fixtures. A method of making a prefabricated wall section includes forming a mold having a gridwork pattern with solid frame members forming hollow cells, placing mold inserts in the formed mold shaped to form passageways of predetermined size and positioning within the frame members, pouring a portion of the prefabricated wall section prior to removing the mold inserts and enclosing the passageways by completing the molding.
