4. Install the Finished Wall
IMPORTANT! If the shower receptor is adjacent to vertical ducts or wiring, the shower receptor must be
surrounded with fire-rated, water-resistant wall material.
Install the wallboard with the factory edge (the paperbound edge) a minimum of 5/8" (15 mm)
above the finished, nailing-in flange threshold of the shower receptor.
Apply silicone sealant to the upper portion of the nailing-in flange where it will meet the
water-resistant wall material.
Ensure the front nailing-in flanges are similarly furred, and the wallboard is sealed to the nailing-in
flange.
Mud, tape, and finish the wallboard.
Seal the joints between the receptor rim and the finished wall with silicone sealant. RTV (Room
Temperature Vulcanizing) sealant is recommended.
5. Complete the Installation
NOTE: Refer to the sealant and/or putty manufacturer's instructions for proper application techniques.
Seal around the valving and outlets with silicone sealant or plumbers putty.
Install the shower trim and drain trim according to the manufacturer's instructions.
Install the shower door according to the manufacturer's instructions.
Install the finished floor.
Apply silicone sealant along the front edge of the receptor where it meets the floor.
