Drain Wall for a Prefabricated Shower Module

摘要

A prefabricated, polyurethane reaction injection molded, leak-proof shower module suitable for use in constructing a tiled shower includes a plurality of sidewalls, a floor bounded along at least one peripheral edge by at least one sidewall extending substantially vertically from the edge, and a drain wall defining a drain aperture and having an outer surface and an inner surface. In one embodiment, the floor slopes toward the drain wall at a pitch equal to or greater than ⅛ inch per foot. A prefabricated drain assembly is integrated into the floor and encased inside the drain wall, or a drain fixture is inserted into the drain aperture after fabrication of the floor. In one embodiment, the maximum thickness of the drain wall, measured from the outer surface to the inner surface, is equal to or less than 1½ times the smallest inner diameter.

主权项

1. A prefabricated, polyurethane reaction injection molded, leak-proof shower module suitable for use in constructing a tiled shower, the shower module comprising:
a floor having an upper surface, a lower surface, and a plurality of peripheral edges, wherein the floor is bounded along at least one peripheral edge by at least one sidewall, the at least one sidewall extending substantially vertically from the at least one peripheral edge, and wherein the floor slopes toward at least one drain wall defining a drain aperture, wherein either:
a prefabricated drain assembly is integrated into the floor and encased inside the drain wall; ora drain fixture is inserted into the drain aperture after fabrication of the floor; and a drain reinforcing structure attached to the drain wall, the drain reinforcing structure embedded in an intermediary position between the upper surface and the lower surface of the floor of the module and laying in a plane which is substantially parallel to either or both of the upper surface and the lower surface of the floor of the module.
