Tools and Materials
Before You Begin
Please read these instructions carefully to familiarize yourself with the required tools, materials, and
installation sequences. Follow the sections that pertain to your particular installation. This will help
you to avoid costly mistakes.
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.
Your shower receptor comes packaged in a single carton. This carton will fit through any standard
door. You should not remove the receptor from the carton until you are ready to install it.
Unpack and inspect the shower receptor for any damage. The receptor should have a front apron
piece already secured to it. This apron does not need to be removed and can remain attached
throughout the installation procedure. If you find any damage, do not install the receptor. Report
the specific problem to your dealer immediately.
After inspection, return the receptor to the carton until you are ready to install it.
The shower receptor must be installed to an adequately supported and level subfloor.
Be sure that you have enough access to move the receptor into the construction area.
Make sure the installation area is clean and free of all debris. If remodeling, remove all finished wall
material to expose the stud wall/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 wiring, 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.
Place the receptor within the installation area prior to completion of the framing.
The basin area requires no additional support when the subfloor is level and square with respect to
the framing. Consider using shims for additional support if the subfloor is uneven.
Consult all applicable instructions for options and accessories before beginning this installation.
Fixture conforms to ANSI Standard Z124.1.2. All dimensions are nominal. All models meet IAPMO
requirements.
Kohler Co. reserves the right to make revisions in the design of products without notice, as specified
in the Price Book.
1. Prepare the Site
Ensure that 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.
Inspect the flooring at the installation site. Repair as necessary.
Make sure the subfloor and finished floors are flat and level.
Kohler Co. 3 1065122-2-A

2. Roughing-In
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.

3. Construct the Stud Framing
IMPORTANT! If a shower door will be installed, refer to the shower door installation instructions for any
special framing considerations.
Construct 2x4 or 2x6 stud framing according to the roughing-in information for your particular
model.
Verify that the framing is square and plumb.
For grab bar installation: Provide 2x6 bridging or attachment at specified positions for grab bar
installations. Refer to the grab bar manufacturer’s instructions.
Verify the subfloor is level. Shim as necessary.

4. Install the Plumbing
NOTE: Provide access at the back of the plumbing wall for servicing the supply and waste piping.
Locate rough plumbing for the drain according to the correct model’s roughing-in dimensions.
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.
Install the shower valving according to the manufacturer’s instructions. Do not install the trim at
this time.
If installing a steam system, position the rough plumbing for the steam head at the intended
installation location at this time. Refer to installation instructions packed with your steam
components for details.
5. Prepare the 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.
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.
6. Position the Receptor
Move the receptor into position. Verify proper fit.
Fit the drain into the trap. Do not connect the trap at this time.
CAUTION: Risk of product damage. If shimming is required, shim between the subfloor or slab
and the wood block feet on the underside of the receptor. All wood block feet must be supported
when the receptor is leveled and nailed to the framing.
Check that the receptor is level in both directions and resting on all feet. Shim if necessary.
Concrete, gypsum cement or other similar materials can be used to level the base.

7. Secure the Receptor to the Stud Framing
CAUTION: Risk of property damage. Make sure a watertight seal exists on all drain connections.
Drill 1/8″(3 mm) pilot holes through the nailing-in flange at each stud location. If needed, shim
between the nailing-in flange and the studs to prevent cracking the flange when drilling.
Complete the drain installation according to the instructions packed with the drain.
Open the water supplies and check all the connections for leaks.
Run water into the receptor and check the drain connections for leaks.
Use #6 large-head galvanized nails or screws to secure the nailing-in flange to the studs.
Nail 1/8″(3 mm) thick furring strips to the studs to shim out to the edge of the nailing-in flange.

8. Complete the Installation
Apply silicone sealant to the upper portion of the nailing-in flange where it will meet the
water-resistant wall material.
Cover the framing, walls, and nailing-in flange with water-resistant wall material. Be sure to install
the water-resistant wall material to the framing with the paperbound edge a maximum of 1/4″(6
mm) above the finished concave surface of the receptor.
Tape and mud the water-resistant wall material.
Install the finished wall.
Seal the joints between the receptor rim and the finished wall with silicone sealant. RTV (Room
Temperature Vulcanizing) sealant is recommended.
Seal around the valving and outlets with silicone sealant or plumbers putty.
Install the faucet and drain trim according to the manufacturer’s instructions.
If applicable, install the grab bar(s) to the backing in the stud wall (previously installed) 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 edges of the receptor and apron where they meet the floor.
Repeat along the vertical edges where the apron meets the wall.
9. Clean-Up
CAUTION: Risk of product damage. Do not allow cleaners containing petroleum distillates to
remain in contact with module surfaces for any length of time.
CAUTION: Risk of product damage. Do not use abrasive cleaners.
When cleaning up after installation, use warm water and an approved liquid cleanser to clean the
surface.
Stubborn stains, paint, or tar can be removed from acrylic surfaces with turpentine or paint thinner.
Plaster can be removed by scraping with a wood edge. Do not use metal scrapers, wire brushes, or
other metal tools. Use warm water and an approved liquid cleanser to provide mild abrasive action
to remove residual plaster.
