Abstract: A shower stall threshold structure has two opposed former sections formed of light weight plastic material and adapted to have mortar poured into the space therebetween. The sections are equipped with spacer members and connection bolts to hold the sections in proper spaced relationship until the mortar hardens. Openings through the former sections expose the mortar at the outer faces of the former sections so that tile placed on the sides of the threshold can be adhered to the mortar. One or both former sections may have tile supporting ledges projecting outwardly from their outer faces. A plastic sheet underlying the shower stall may have its edges turned upwardly within the threshold and held in place between the spacer members on the sections. Lines of weakness are provided in the former sections to permit portions of the sections to be broken off to reduce the height of the threshold.
Abstract: A free-standing shower permits remote drain discharge, having a shower cabinet with wall structure defining a peripheral base edge fitted upon or interengaged with a base extension formed of identical, interlocked members. A lightweight, foam material sub-base is provided under the shower floor, which is raised above the supportive surface by the base extension. The sub-base guides and locates a drain pipe assembly including a drain pipe which extends laterally through and beyond the sub-base to permit drain discharge at a location remote from the shower.
Abstract: A shipboard bathroom module comprises a prefabricated base pan in which a floor drain and a shower drain are located adjacent to each other but on opposite sides of a shower stall curb. Both drains communicate with a common receptacle molded into the base. Water from a wash basin at a remote location within the module is conducted to the receptacle through the shower stall curb, which is hollow. A trap, which serves both drains as well as the wash basin, is located in a box which provides a recess in the deck. In one version of the invention the receptacle built into the bathroom base sits on top of the trap, and the trap is accessible through one of the drain openings in the floor of the module. In another version, wastewater is conducted out of the receptacle through a laterally extending conduit to a trap which serves two adjacent bathroom modules. In either case, the box in which the trap is located is prefabricated with various water supply and drain pipes already welded to its floor.
Abstract: An improvement in a shower stall having a curtain extending between walls forming the stall is provided, said stall having a receptacle in which a person may stand while showering, said receptacle having a rim capable of allowing water to run along its top surface between the walls and the curtain out of the shower stall, the improvement being a water dam comprising a strip adapted to be affixed to the top surface of the rim of the receptacle in abutment with a wall of the stall near an end of the curtain and further adapted to traverse the top surface of the rim and continue a short distance down into the receptacle.
Abstract: A two-piece shower stall formed as an integral unit and thereafter separated and reassembled after placing a gasket intermediate an upper and lower section formed by the separation. A securing belt is preferably formed integral with the one-piece unit at the area of intended separation and serves to reinforce the shower stall during separation and provide a means for releasably securing the upper section and lower section together. The gasket intermediate the upper section and lower section preferably extends into the interior of the shower stall to provide a watertight seal.
Abstract: A two piece molded fiberglass shower unit includes a square base having a vertical peripheral ridge extending along three sides of the base and a single piece shower wall section. The wall section includes a continuous groove for receiving the ridge. The ridge fits tightly into the receiving groove, preventing leakage of water through the junction between the base and the wall section and rigidly attaching the wall section to the base.
Abstract: A shower receptor drain assembly includes a generally cylindrical drain body having a flange extending upwardly from the upper end thereof. An inner flange extends radially inwardly from the lower edge of the drain body, and is provided with an inner diameter which permits a waste discharge pipe to extend upwardly therein. A plurality of bosses extend upwardly from the inner flange and are spaced equally thereabout. An annular sealing gasket is disposed within the drain body and received about the upper end of the waste discharge pipe. A compression ring is disposed directly superjacently of the sealing gasket, and a plurality of screws extend through the ring and through aligned passages in the gasket to be retained in tapped holes in the plurality of bosses. The screws cause compression of the sealing gasket to effect a leak-proof seal of the waste pipe within the drain body.
Abstract: A shower bath, sink, or other fluid receiving vessel is described wherein heat is reclaimed from the drain fluid to warm the incoming cold water to reduce the amount of hot water which must be mixed in to produce water of the temperature desired for use within the vessel. The improvement consists of a cover pan for collecting the received fluid and depositing it on a particular region of the vessel floor which is contoured to direct the received fluid along a particular channel to a drain. The cold water supply tube is positioned within the channel in contact with the draining fluid. The warmer drain fluid transfers heat energy into the cooler water flowing within the submerged cold water supply tube.
Abstract: A doorless shower stall which confines water such that it cannot be sprayed nor splashed outside of the stall is disclosed. The stall includes a shower chamber area which is enclosed except for an entry passage to the shower chamber. Connected to the shower chamber area by the entry passage is an antechamber having a primary entry way which leads outside of the shower stall and which primary entry way is substantially perpendicular to the entry passage into the shower chamber. In a preferred embodiment, the shower stall is manufactured of molded fiberglass or other material which includes a floor which slopes such that water in the antechamber runs away from the primary entry way and through the entry passage into the shower chamber. The floor of the shower chamber is itself sloped toward a drain located at a desired location in the shower chamber. The shower stall may further include a molded fiberglass cap or ceiling to further prevent escaping moisture from causing damage outside of the shower stall.
Abstract: A drain for a prefabricated shower stall that can be quickly and easily connected to a drain pipe, even though the drain pipe might be off-center with respect to the shower drain opening. The drain consists of two interfitting parts, a first of which is a drain body designed for attachment to the shower stall, and the second of which is a bushing-like member designed to interconnect the drain body and drain pipe. The drain body has a round opening, with a converging wall, extending through it, and an outwardly extending flange by means of which it can be affixed to a prefabricated shower stall around the drain opening in the stall. The converging wall of the opening in the drain body serves as a seat for the second part of the drain, which has a frustoconical outer wall to make this possible. This second part has a cylindrical bore concentric with its outer wall and is of such size as to extend below the first part, when seated therein, and telescopically receive the drain pipe in its cylindrical bore.
