1. After deciding on the location of your wall shower drain, cut out a 7 inch piece of the floor plate.
2. Using a hole saw, cut 2 3/4 to 3 inch diameter hole in the sub-floor, centered in the cutout and 1/8 inch from the front edge of the plate.
3. If intending to mud in the floor, the top of the floor flange of the drain should be at least 3/4 inch above the sub-floor.
4. Secure Invisidrain in position. Using the pre-drilled holes, screw Invisidrain to the studs, floor plate and/or additional framing.
5. Cover the screw heads with thin-set.
6. Install shower wall-board flush with Invisidrain edges.
7. Install mud floor. (if using pre-sloped floor see note below)
8. Apply flexible sealant caulk to the joints and corners.
9. Install membrane or sheathing of your choice over drain box flanges.
   • If using paintable membrane, install one coat of membrane to all drain surfaces to be tiled. Install 6 inch fiberglass tape with thin-set and use 2 coats of liquid membrane.
   • If using sheathing membrane, apply one coat of liquid membrane to all surfaces you intend to tile, including the removable door face.
10. Install tile to intended surfaces, including Invisidrain flanges and the front of the removable door face.
    • Tile should extend 1/4 of an inch below the top of the drain box opening.
    • Removable door tile should be 2 9/16 inches high x 7 1/4 inches wide.
    • For proper drainage, a gap of 1/2 inch should be maintained from bottom of door to finished tile floor.

NOTE: If using pre-sloped flooring product, follow manufacturers instructions and flush the floor to the top of the Invisidrain floor flange.
