Abstract
A shower trench drain apparatus includes a shower trench drain body of polymeric material having an integrally-formed drain channel with angled bottom surface and drain opening or openings, a waterproof membrane over the drain body, a clamp ring retaining the membrane to the drain body, and a grate adjustably retained to the drain body by a height adjustment mechanism. The trench drain body formed from a block of material such as PVC or ABS, which are compatible with approved plumbing materials and codes. The block has a flat bottom adapted for horizontal support during installation and includes integrally-formed features facilitating adjustment during installation while minimizing components and separate parts and simplicity of installation.
Claims17
A shower trench drain apparatus comprising:
- a water collecting trench drain body including a block of material formed to include a flat bottom surface and a drain channel with an angled channel bottom surface, the flat bottom surface extending a width and length of the drain channel, and the block including a non-uniformly-thick solid mass of material extending between and forming both the flat bottom surface and the channel bottom surface.
A shower trench drain apparatus comprising:
- a water collecting trench drain body including a block of material having a flat bottom extending a width and length to define an enlarged horizontal surface area configured to stably rest on a level horizontal support surface during installation, and an integrally-formed up-facing drain channel with angled bottom surface, the block including non-uniformly-thick material extending between and forming both the flat bottom and the angled bottom surface.
A shower trench drain apparatus comprising:
- a shower trench drain body of polymeric material including a flat bottom surface extending a width and length of the drain channel, and an integrally-formed drain channel with angled bottom surface and at least one drain opening, the body including a non-uniformly-thick solid mass of material extending between and forming both the flat bottom surface and the angled bottom surface;
- a waterproof membrane over the drain body;
- a clamp ring retaining the membrane to the drain body;
- and
- a grate adjustably retained to the drain body by a height adjustment mechanism.
A method of constructing a shower trench drain apparatus comprising steps of:
- providing a block of polymeric material having a flat bottom surface;
- machining the block to form a shower trench drain body of polymeric material including the flat bottom surface, an integrally-formed drain channel with angled bottom surface, and at least one drain opening;
- supporting the body by resting the flat bottom surface on a mating level horizontal flat support surface in an installation;
- laying a waterproof membrane over the drain body;
- clamping the membrane onto the body using a clamp ring;
- and
- attaching a grate adjustably to the drain body with an adjusted height that matches a final floor surface of a shower.
