Installing on Floor Joists
1. Place the drain on the floor and up against the wall you want to use to drain the shower (for placement in another location on the shower floor, please call us if you have any questions).
2. Plumb the drain from the bottom discharge opening to a new or existing P-Trap in the floor. Thread a Male Plumbing Adapter (Copper, PVC or Galvanized) into the discharge hole (NOTE: A 2" Compression fitting is also an option). If possible, install the p-trap so that it is accessible from the basement or crawl space. If you don't have access to the p-trap from below, you may want to consider a drain grate.
3. If you are pouring concrete, place screet guides for proper slope to the drain on opposite edges of the shower. Be careful to allow ample slope to the drain (1/4" per foot is ideal). Allow 24 hours for floor/pan to dry before moving ahead.
4. When waterproofing your shower floor on top (rather than the Traditional way, with a Pan Liner), we can supply your drain with a waterproof flange using the fabric membrane of your choice.
5. On the wall with the trench drain, please make sure the DuraRock (or similar 1/2" or thicker tile backer board) is flush with or preferably extends beyond the back and side inside edges of the drain. Leave the bottom of the backer boards about 1/4" above the top edge of the drain so the membrane can be easily applied to the front of the backer board without pinching the membrane.
6. When installing the tile on the back wall, allow the tile to extend into the drain 1/4" to 1/2".
7. When laying the shower floor tile, allow it to come within 1/8”- 3/16" from the tile against the front wall (This will create a sleek, almost unnoticeable line that the water will simply cascade into and disappear).
NOTE: If you don’t have access to the p-trap from below, contact us to discuss options for accessing the drain discharge from above.
NOTE: This is the perfect drain for an ADA - Handicapped Accessible Shower!
