Abstract: A prefabricated shower bench for installation in a tiled shower includes an upper surface having a plurality of peripheral edges, and at least three sidewalls. Each sidewall has an upper edge and a lower edge. Each upper edge is connected along a corresponding peripheral edge of the upper surface. The lower edge of each sidewall terminates in a common plane. One sidewall includes a setback area along the entire lower edge which has a height greater than the height of a sidewall of a prefabricated shower module. The upper surface is horizontal or pitched downwards toward the shower module when the shower bench is installed adjacent to the sidewall of the shower module such that the sidewall of the shower module resides within the setback area, thereby preventing the weight of the shower bench from resting on the sidewall of the shower module.

The sidewall has an upper edge and a lower edge. The upper edge is connected along a corresponding peripheral edge of the seating member. The lower edge terminates at a height above the ground which is the same as or slightly greater than the height of a corresponding sidewall of a prefabricated shower module. The upper surface is horizontal or pitched slightly downward toward the shower module when the shower bench is installed adjacent to the sidewall of the shower module. The lower edge of the downwardly depending sidewall is situated substantially in registry with an upper edge of the prefabricated shower module sidewall. The prefabricated shower module sidewall is in a plane that is substantially contiguous with a plane formed by the downwardly depending sidewall of the bench.

Abstract: A bathroom floor module adapted to be used in conjunction with a fully or partially curbless, such as one which is handicapped-accessible, waterproof shower module, where the bathroom floor module or may not define one or more drain apertures adapted to mate with a bathroom floor drain, and further wherein the bathroom floor module and waterproof shower module mate in such a way as to define a contiguous surface over which bathroom floor and/or wall tile can be applied to create a transition between bathroom floor and shower over which a wheelchair can be easily rolled.

Abstract: A waterproofing flashing and resulting juncture, comprising in a first embodiment a generally horizontally positioned planar member which is positioned in sandwiched engagement between the upper peripheral edge of a shower pan or shower bench sidewall (or equivalent wallboard) and a lower peripheral edge of adjacent wallboard (or equivalent shower bench, shelf or ledge), and a vertically extending member attached to a distal edge of the horizontal member extending vertically upwardly behind the wallboard (or equivalent shower bench, shelf or ledge). An alternative form of the invention comprises a T-shaped flashing member comprised of a mid-section to which are connected first and second attachment members or wings, the wings adapted to connect the flashing to the room-facing side of the wallboard and/or shower module sections.

Abstract: A method of manufacturing a leak-proof shower module suitable for use in constructing a tiled shower is implemented in one embodiment when a manufacturer provides a tool for creating the leak-proof shower module. The tool includes a cavity portion and a core portion which define a shape corresponding to the shape of the shower module. Next, the manufacturer inserts at least one form into the tool between the cavity portion and the core portion at a location corresponding to a drain aperture, injects a polymeric material into the tool to produce the shower module, and removes the shower module from the tool while retaining the form in place. In one embodiment, the manufacturer clamps the shower module to a rigid surface such that the module is prevented from flexing and the drain aperture rests in a hole in the rigid surface, and cools the shower module while retaining the form.

Abstract: A prefabricated, polyurethane reaction injection molded, leak-proof shower module suitable for use in constructing a tiled shower includes a plurality of sidewalls (101, 102, 103, 104), a floor (110) and a plurality of ribs (120) connected to the floor. The floor has an upper surface, a lower surface, and a plurality of peripheral edges and is bounded along at least one peripheral edge by at least one sidewall that extends substantially vertically from the at least one peripheral edge. Each rib extends parallel to, perpendicular to, or at an acute angle to at least one peripheral edge and runs toward at least one drain wall and terminates in an outer edge lying in a common plane. In one embodiment, the upper surface slopes downward toward the drain wall at a pitch of ? inch per foot or greater and each rib extends downward from the lower surface, resulting in a horizontal common plane.

Abstract: A prefabricated, polyurethane reaction injection molded, leak-proof shower module suitable for use in constructing a tiled shower includes a floor and a plurality of sidewalls wherein a first sidewall is taller than at least a portion of a second sidewall and the difference in height between the first sidewall and the second sidewall is sufficient to permit the attachment of a modular curb to the second sidewall. The floor is bounded along peripheral edges by the plurality of sidewalls which extend substantially vertically from the edges. A method of installing a tiled shower is implemented in one embodiment by applying adhesive material on a subfloor within an area bounded by stud framing, setting the prefabricated shower module in place on the subfloor, installing a prefabricated modular curb proximate to at least one sidewall of the module, attaching wallboard to the framing, and installing tile over the wallboard, module and curb.

Abstract: A prefabricated shower bench for installation in a tiled shower includes an upper surface having a plurality of peripheral edges, and at least three sidewalls. Each sidewall has an upper edge and a lower edge. Each upper edge is connected along a corresponding peripheral edge of the upper surface. The lower edge of each sidewall terminates in a common plane.
