A low profile drain includes a first extrusion channel extending lengthwise in a first direction, a second extrusion channel extending lengthwise in the first direction, and a connection channel extending lengthwise in the first direction. The connection channel is configured to interlock with an end of the first extrusion channel via a first interlocking mechanism, and interlock with an end of the second extrusion channel via a second interlocking mechanism. The first interlocking mechanism includes at least one first angular protrusion disposed on the first extrusion channel, and a first angular recess disposed on the connection channel. The at least one first angular protrusion is configured to interlock with the first angular recess.

Described is a prefabricated bathtub or shower pan with curved outer edges and an elevated threshold that act as returning points for water. More specifically, the bathtub or shower pan are formed to include a drain area surrounded by interior sides and a threshold dam. A side ledge is formed atop each of the interior sides, each side ledge having a top edge. Surrounding walls rise from the top edge of each side ledge. Further, the threshold dam has an angled top surface with a lower edge. Notably, the lower edge of the angled top surface is higher than the top edge of each of the side ledges to prevent, any water from running from the side ledges onto the threshold dam. The bathtub or shower pan also include curved outer edges that transition from a side wall and onto the threshold dam to return water to the drain area.

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.

A combination for plumbing fixtures, particularly tiled floors with drains, is disclosed. An exemplary combination includes a substantially planar shower tray bonding disk on a flooring substrate and surrounded by a prefabricated polymer foam shower tray on the flooring substrate and at the circumference of the bonding disk. The disk includes an interior rim that defines a drain opening and a plurality of slotted openings for permitting mortar to penetrate the disk. The drain opening in the disk can thus be positioned at a drain cut out in the flooring substrate.

Methods and apparatus for creating a shower or bath enclosure, in which, given a predetermined area in which to create the shower or bath, a given prefabricated water proof bath or shower floor module is too small to occupy the entire available enclosure space. The apparatus includes the use of one or more additional enclosure components, such as one or more shower benches, to occupy a space between an edge or edges of the floor module and the exterior boundary(ies) of the enclosure space.

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.
