The drain body may be connected to the shower bed or shower pan by any suitable means, such as but not by way of limitation by being integrally molded therewith during the manufacture of the pan, by connection post-manufacture, or in situ in the field. The cover, which is defined by a peripheral edge supported by horizontal cantilevered posts, is adapted to lie in registry with, and thereby cover, the drain aperture perforating the threaded flanged pipe. In this way, water is permitted to exit the shower or bath without the drain aperture being visible.

  • Patent number: 8973178
    Abstract: A heat exchanger for a shower tray can be arranged in the bottom of the shower tray for the heat recovery from wastewater so as to heat fresh water. To this end, the heat exchanger has a planar cover plate as the drain surface over which the wastewater drains. The cover plate forms the bottom of the shower tray, over which a lid that can be removed without the use of tools is arranged as a tread plate. The heat exchanger preferably includes a distributor element, which is arranged for distributing the wastewater over the drain surface. The distributor element is preferably a retaining element, which retains the wastewater at an upper edge of the drain surface and forms an overflow along the upper edge.

  • Publication number: 20150026879
    Abstract: The invention relates to a one-piece shower pan with no openings for water leakage, other than the drain hole, and designed for easy installation of tiles of various thicknesses. The shower pan comprises 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 waterdam with a fin extending vertically on the outer edge of the waterdam as added protection against water migration outside the shower pan.

  • Patent number: 8925123
    Abstract: A segmented drain system comprises a drain body, operable to mate with a drain fitting installed in a bath or shower area, and a bonding flange body, adjustable relative to the drain body. An integrated bonding flange extends from the bonding flange body, the integrated bonding flange being operable to be sealably attached to a bondable waterproof membrane to provide a substantially water-tight seal between the membrane and the bonding flange body. A seal is oriented between the integrated bonding flange body and the drain body, the seal being operable to provide a slidable, substantially water-tight interface between the integrated bonding flange body and the drain body.

  • Publication number: 20150000029
    Abstract: 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 ? 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.

  • Patent number: 8918926
    Abstract: A one piece shower drain pan, encapsulated in a water proof membrane, wherein one embodiment provides a one piece shower pan which includes a recessed drain portion supporting a square insert made of pvc or poly vinyl material which includes a plurality of drain channels extending from the outer edge of each wall of the insert into the recessed drain portion. The insert would be covered by tile members similar to the tiles of the shower floor, so to provide the visual effect of no drainage opening in the floor of the shower. There would be provided a perimeter water flow space between the side edges of the tiles covering the insert and the edges of the surrounding tiles, so that water flowing onto the floor of the shower would flow through the perimeter water flow space, through the drain channels and into the main drain.

    Abstract: A floor support structure for a bathtub or a shower tray floor, taking the form of a separate element to be used in conjunction with a traditional bathtub or shower tray floor, or as a unitary shower tray floor formed with the support structure integrated therein. The supports include a hollow plastic shell having a lower surface for lying on a planar subfloor, an upper surface contoured to the desired shape and a peripheral sidewall extending there between. Preferably, a drain hole is formed in the plastic shell which also interconnects the upper and lower surfaces thereby defining a hollow interior cavity. The cavity is filled with expandable thermoplastic foam beads which are expanded in place with steam in order to substantially fill the interior cavity thermally bonding the beads together and to the shell interior wall. The expanded foam bead is capable of being compressed without substantial permanent set.
