Trench shower drain
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.
1. 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.
2. The shower trench drain apparatus defined in claim 1 , wherein the block has a polygonal configuration and has a top surface shaped to matably receive and matably engage a drain cover.
3. The shower trench drain apparatus defined in claim 1 , including a pre-drain strainer shaped to fit into the drain channel.
4. The shower trench drain apparatus defined in claim 1 , including a clamp mechanism adapted to mechanically fasten a waterproofing membrane to a top of the drain body.
5. The shower trench drain apparatus defined in claim 1 , wherein the body includes standoffs adjustably engaging a grate in a manner that allows for appropriate adjustment to a finished floor height.
6. The shower trench drain apparatus defined in claim 1 , wherein the body includes an exit hole that allows for direct coupling of a rough drain pipe stub without the need for additional fittings.
7. The shower trench drain apparatus defined in claim 1 , wherein the body bottom structure that is adapted to be mechanically fastened to a flat subfloor of a building structure.
8. The shower trench drain apparatus defined in claim 1 , wherein the drain body includes one or more drain exit holes.
9. The shower trench drain apparatus defined in claim 1 , wherein the block of material includes a polymeric material.
10. The shower trench drain apparatus defined in claim 9 , wherein the polymeric material is one of a PVC and ABS material.
11. 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.
12. The shower trench drain apparatus defined in claim 11 , wherein the block of material includes a polymeric material.
13. The shower trench drain apparatus defined in claim 12 , wherein the polymeric material is one of a PVC and ABS material.
14. 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.
15. The shower trench drain apparatus defined in claim 14 , wherein the polymeric material is one of PVS and ABS.
16. 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.
17. The method defined in claim 16 , wherein the drain body includes a non-uniformly-thick solid mass of material extending between and forming both the flat bottom surface and the angled bottom surface.
