Before You Begin
Observe all local plumbing and building codes.
Locate the rough plumbing for the drain in accordance with the roughing-in dimensions for your particular model.
A variety of installations are possible. These instructions show suggested installation procedures, your particular installation may require other construction techniques.
Please read these instructions carefully to familiarize yourself with the required tools, materials, and installation sequences.
Your shower receptor comes packaged in a single carton containing a one-piece shower receptor. This carton will fit through any standard door. You should not remove the receptor from the package until you are ready to install it.
Unpack and inspect the shower receptor for damage. If you find any damage, do not install the receptor. Report the specific problem to your dealer immediately.
After inspection, return the shower receptor to the carton until you are ready to install it. The shower receptor must be installed to an adequately supported, level subfloor. Before installing the stud framing for the shower receptor, locate a 2(5.1 cm) diameter drain pipe
that extends 3/8(1 cm) above the subfloor. Make sure the installation area is clean and free of all debris. If remodeling, remove all finished wall
material to expose the framing and remove all floor coverings to expose the subfloor. Provide properly dimensioned framing. This shower receptor is designed for an alcove installation. The exact location of the end studs will depend on the thickness of the finished wall material.

Before You Begin (cont.)
If the unit will be adjacent to vertical ducts or chases, surround the unit with fire-rated, water-resistant wall material.
When fire-rated wall material is specified, stud-opening dimensions are toward the exposed side of the wall material.

IMPORTANT! All dimensions are nominal. The stud opening tolerance is +1/4(6 mm) and -0 (0 mm). Carefully measure your fixture before determining enclosure size. When a fire-rated wall is specified, dimensions are to the inside of the wall board. Some shimming between the stud frame and the fixture may be required. Dimensions given in the roughing-in information are crucial for proper installation. Construct the framing and plumbing accurately.
NOTE: If a firewall is required, increase the roughing-in dimensions according to the thickness of the firewall material. Stud opening dimensions must be measured toward the exposed side of the wall material.
NOTE: If the unit will be installed against a masonry wall, make provisions for plumbing connections. Construct a separate frame wall a minimum of 6(15.2 cm) from the masonry wall.

1. Install the Plumbing
NOTE: Follow all local codes, standards, and regulations.
Locate rough plumbing for the drain according to the correct model’s roughing-in dimensions. Refer to the roughing-in provided with this guide.
NOTE: If the plumbing will be located on the unfinished stud wall, install the supplies after the receptor is installed.
Position the plumbing according to the roughing-in information. Cap the supplies and check for leaks. Install a 2(5.1 cm) diameter drain line to extend 3/8(1 cm) above the subfloor or slab. A pocket is
required in a slab construction to accommodate the drain fitting. Provide access at the back of the plumbing wall to make drain connections to the receptor.

2. Construct the Stud Framing
IMPORTANT! If a shower door will be installed, refer to the shower door installation instructions for any special framing considerations.
NOTE: Additional support is not required for the shower receptor if the subfloor is plumb and level with respect to the stud framing. If the subfloor is not level, shimming may be required to level the unit.
NOTE: Stud pocket tolerance is +1/4 (6 mm), -0 (-0 mm) when fire-rated material wall is specified. Dimensions are to the inside of the wallboard.
Construct 2x4 or 2x6 stud framing according to the roughing-in information for your particular model.
NOTE: If necessary, leave one of the stud pocket walls loose until the shower receptor is moved into position. After the receptor has been moved into position, align and fasten the remaining wall in the stud pocket.
Provide double or triple stud framing around the opening of the stud pocket. Verify that the stud pocket framing is square and plumb. Verify the subfloor is level. Shim as necessary.

3. Prepare the Receptor
WARNING: Risk of product or property damage. Do not support the shower receptor by the rim. The weight of the shower receptor should be supported by the bottom of the shower receptor.
CAUTION: Risk of product or property damage. If a watertight seal on the drain is not obtained, water damage to the receptor bottom and the subfloor may occur.
Install the drain to the shower receptor according to the drain manufacturer’s instructions. Follow all local building codes, standards, and regulations.
Make sure the shower receptor is level and the bottom of the shower receptor is resting on the subfloor. Shim as necessary.
Clean the shower receptor to reduce the risk of surface damage, then place a clean drop cloth or other similar material into the bottom of the shower receptor. This will ensure the unit will not scratch during the installation process.
4. Secure the Receptor
Drill 1/8(3 mm) holes through the nailing-in flange at all stud locations. If needed, shim between the nailing-in flange and the stud to prevent cracking while drilling and to remove any gap between the studs and the nailing-in flange.
Secure the nailing-in flange to the studs with screws or galvanized screws. Attach 1/4furring strips to the studs around the receptor. Attach the drain to the P-trap according to the manufacturer’s instructions. Follow all local building
codes, standards, and regulations. Install the faucet valving. Open the water supplies and check all connections for leaks.

5. Install the Finished Wall Material
IMPORTANT! If the shower receptor is adjacent to vertical ducts or chases, 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.
6. 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.

7. Clean-Up
Consult the care and cleaning directions in the Homeowners Guide before cleaning the unit. When cleaning up after installation, do not use abrasive cleansers, as they might scratch and dull
the product surface. Remove stubborn stains, paint, or tar with turpentine or paint thinner. Do not allow cleaners containing petroleum distillates to remain in contact with the product surfaces
for any length of time. Remove plaster by scraping the surface with a wood edge. Do not use metal or wire tools. Use a
powder type detergent on a damp cloth to provide mild abrasive action to the residual plaster.
