Described is a one-piece shower pan with a seat having no openings for water leakage, other than the drain hole. The shower pan includes a drain hole designed to fit a conventional drain pipe such that when the conventional drain pipe is fastened to the shower pan, the conventional drain pipe extends ½ to 2 inches above the bottom of the shower pan. In this way, when cement or other adhesive is floated on the interior surface of the shower pan, tiles of varying thickness can be installed in such a manner that the top surface of the tiles are substantially flush with the top portion of the conventional drain pipe. The shower pan also has a water dam with a fin extending vertically on the outer edge of the water dam as added protection against water migration outside the shower pan.

A drainable floor and linear drain, the drainable floor having an integral trench associated therewith, the trench comprising sidewall and a trench floor, and one or more floor covering panels positioned in registry with the drainable floor, where the one or more floor covering panels cover a portion of the projection of the trench floor, while leaving at least one other portion of the trench floor uncovered by such one or more floor covering panels.

The method of producing a shower tray using a shower tray blank is disclosed. The method may comprise identifying a drain location on the shower tray blank. The method may further comprise deflecting the shower tray blank at an internal location relative to a shower tray perimeter of the shower tray blank along the depth dimension to a deflected state. The method may also comprise cutting the shower tray blank along a plane generally perpendicular to a depth dimension of the shower tray blank when the shower tray blank is in the deflected state to form the shower tray and a discarded portion. An apparatus for producing a shower tray is also disclosed.

A one-piece shower base includes a pitched bottom surface, a plurality of vertical flanges extending upward from a plurality of outer edges of the one-piece shower base, a drain integrated within the one-piece shower base, and a pitched foam support base having an upper surface and a lower surface. The pitched bottom surface is pitched downward in at least one direction toward the drain. The upper surface of the pitched foam support base is adhered to an underside of the pitched bottom surface. The pitched foam support base fills in a hollow space below the underside of the pitched bottom surface created by the pitch of the pitched bottom surface.

A method for the manufacture and decoration of a mineral-filled resin shower tray with an external coating, including the steps of applying an external coating layer on the internal surface of a mould, casting a mix of resin and mineral filler on the mould, curing and drying the mix, and including the prior steps of disposing on the internal surface of the mould cavity a transfer film including on one of the sides thereof a pattern printed in ink, vacuum thermoforming the transfer film against the internal surface of the mould cavity, and the subsequent step of removing the film from the surface of the mineral-filled resin shower tray with an external coating.

Apparatus and methods for constructing a shower pan. The shower pan is constructed from wedge panels having a foam core and facers on major surfaces of the wedge panels. The wedge panels are cut into portions that fit regions of the shower pan area. The wedge panel portions are placed in the regions such that the sloped upper surfaces of the wedge panel portions collectively form a continuous surface that at all locations slopes downward toward the drain of the shower. Pans for a wide variety of shower shapes and sizes can be constructed. The shower pan may be efficiently constructed on-site, often using common tools and techniques.
