Step 1: Install the Cement Backer Board

Install cement backer board in the shower stall once the plumbing is complete.

Paint the cement backer board with waterproof membrane paint. Make sure the membrane covers all surfaces of the shower.

Step 3: Install a Rubber Bladder

Install a rubber bladder into the pan of the shower.

Step 4: Cut a Hole and Apply the Silicone Seal

Cut a hole around the drain. Apply the silicone seal to the bladder to the drain.
