NOTICE: Do not lift the whirlpool by the piping or pump, or use the piping or pump for structural

support of the whirlpool. To avoid damage to the whirlpool, lift at the sides of the whirlpool.

must be adequately supported, but must not support the load weight of the whirlpool.

For whirlpools without an apron, a drop-in installation is necessary. For whirlpools with integral or

optional apron, an alcove or corner installation is recommended, depending upon the model chosen.

Inspect the whirlpool for damage before you begin installation.

You must install this whirlpool to an adequately supported, level subﬂoor.

Conﬁrm adequate mounting and connection space for the faucet speciﬁed for your installation.

For corner units with integral apron: Have a qualiﬁed electrician install the outlets for the pump

1. Prepare the Site

NOTICE: Refer to the Roughing-in Guide packed with your bath whirlpool for the required minimum

lb/square foot (kg/square meter) ﬂoor support.

NOTICE: Do not lift the whirlpool by the piping or pump, or use the piping or pump for structural

support of the whirlpool. To avoid damage to the whirlpool, lift at the sides of the whirlpool.

NOTICE: Do not support the load weight of the whirlpool by the perimeter of the rim. The rim perimeter

must be adequately supported, but must not support the load weight of the whirlpool.

Make sure the ﬂooring offers adequate support for your whirlpool, and verify that the subﬂoor is

ﬂat and level.

For Whirlpools without Apron:

NOTICE: The whirlpool should be installed in a drop-in installation.

Construct 2x4 or 2x6 stud framing for your installation.

NOTICE: When planning the construction of the site, take into consideration that the whirlpool must be

supported by its feet or base to avoid product damage. Do not support the load weight of the whirlpool

by the perimeter of the rim. The rim perimeter must be adequately supported, but must not support the

load weight of the whirlpool. This includes whirlpools placed in alcove installations.

For a raised installation: Frame the ﬂoor or construct a frame in accordance with the roughing-in

information packed with the whirlpool.

Carefully lay out and cut the rough deck material. Use the cut-out template if one is provided, or

refer to the roughing-in cut-out information.

For Whirlpools with Integral or Optional Apron:

The whirlpool should be installed in an alcove or corner installation, depending upon the model

chosen. Construct 2x4 or 2x6 stud framing designed for your particular installation. Construct a

frame in accordance with the roughing-in information packed with the whirlpool.

For All Installations:

Position the plumbing according to the roughing-in information packed. Cap the supplies, and

check for leaks.

Frame the floor

according to the

roughing-in information.

2. Prepare the Whirlpool

Install the drain to the whirlpool according to the drain manufacturer’s instructions. Do not connect

the trap at this time.

Position a clean drop cloth or similar material in the bottom of the whirlpool. Be careful not to

scratch the surface of the whirlpool.

Kohler Co. 7 1011092-2-E

3. Secure the Whirlpool — Models With Support Blocks

NOTICE: Do not lift the whirlpool by the piping or pump, or use the piping or pump for structural

support of the whirlpool. To avoid damage to the whirlpool, lift at the sides of the whirlpool.

NOTICE: Do not support the load weight of the whirlpool by the perimeter of the rim. The rim perimeter

must be adequately supported, but must not support the load weight of the whirlpool.

If the subﬂoor is not level, shim the whirlpool support blocks as necessary.

Choose the installation option that best applies to your particular installation. Follow the appropriate

instructions.

Option Using a Cement or Mortar Bed

NOTE: Do not use gypsum cement or drywall compound for this application, as they will not provide an

acceptable, durable bond.

NOTE: The pump support bracket (when the pump banding straps are cut) and support blocks must

rest directly on the subﬂoor.

Spread a 2″(5.1 cm) thick layer of cement or mortar on the subﬂoor where the whirlpool will be set.

This will help secure, level, and support the unit. Clear all the material away from the pump

support bracket and support block locations.

Position a piece of plastic drop cloth material on top of the cement or mortar bed. With help,

carefully lift the whirlpool into place, and make sure the pump support bracket and support blocks

do not rest in the bed material.

Insert the drain tailpiece into the trap. Make sure the whirlpool is level and resting on all support

blocks.

Option Using Construction Adhesive

Apply a generous amount of high-quality construction adhesive to the bottom of the support blocks.

With help, carefully lift the whirlpool into position.

Insert the drain tailpiece into the trap. Make sure the whirlpool is level and resting on all support

blocks.

Clear space for pump.

Spread a 2" (5.1 cm) layer of

4. Secure the Whirlpool — Models With Whirlpool Base

NOTICE: Do not lift the whirlpool by the piping or pump, or use the piping or pump for structural

support of the whirlpool. To avoid damage to the whirlpool, lift at the sides of the whirlpool.

NOTICE: Do not support the load weight of the whirlpool by the perimeter of the rim. The rim perimeter

must be adequately supported, but must not support the load weight of the whirlpool.

Choose the installation option that best applies to your particular installation. Follow the appropriate

instructions.

If the subﬂoor is not level, shim the whirlpool base as necessary.

Option Using a Cement or Mortar Bed

NOTE: Do not use gypsum cement or drywall compound for this application, as they will not provide an

acceptable, durable bond.

Spread a 2″(5.1 cm) thick layer of cement or mortar on the subﬂoor where the whirlpool will be set.

This will help secure, level, and support the unit.

Position a piece of plastic drop cloth material on top of the cement or mortar bed. With help,

carefully lift the whirlpool into place.

Insert the drain tailpiece into the trap. Make sure the whirlpool is level. Use screws or lag bolts (not

provided) to secure the whirlpool base to the ﬂoor. Drill small pilot holes through the whirlpool

base as needed.

Option Using Construction Adhesive

Apply a generous amount of high-quality construction adhesive to the bottom of the whirlpool base.

With help, carefully lift the whirlpool into position.

Insert the drain tailpiece into the trap. Make sure the whirlpool is level. Use screws or lag bolts (not

provided) to secure the whirlpool base to the ﬂoor. Drill small pilot holes through the whirlpool

base as needed.

Spread a 2" (5.1 cm) layer of

cement or mortar bed material.

Kohler Co. 9 1011092-2-E

5. Secure the Whirlpool to the Stud Framing

Drill a small pilot hole through the nailing-in ﬂange at each stud. Add shims between the nailing-in

ﬂange and the studs as needed to eliminate gaps.

Nail 1/4″(6 mm) thick furring strips to the studs to shim out to the edge of the nailing-in ﬂange.

Use #6 large-head galvanized nails to secure the nailing-in ﬂange to the studs.

6. Cut the Pump Banding Straps

IMPORTANT! This step is necessary to make your Kohler whirlpool operate more quietly.

NOTE: Do not raise the pump higher than it was before you cut the pump banding straps. If the pump is

raised too high, it will not prime properly.

Use tin snips to cut the two pump banding straps. When the banding straps are cut, the pump

support bracket and pump will drop about 1/2″(1.3 cm) until they rest on the subﬂoor. If the pump

drops more than 1/2″(1.3 cm), shim under the pump support bracket so there is a 1/2″(1.3 cm)

gap between the pump and bracket to allow for proper drainage.

To minimize whirlpool noise and vibration, be sure the pump is not in direct contact with the

shipping bracket after the pump banding straps are cut.

Secure the pump support bracket to the subﬂoor with screws or lag bolts (not provided).

7. Install the Plumbing

CAUTION: Risk of property damage. A watertight seal must exist on the whirlpool drain. The

watertight seal will prevent property damage.

Connect the drain to the trap according to the drain manufacturer’s instructions.

Install the faucet valving according to the faucet manufacturer’s instructions. Do not install the

faucet trim until instructed. Open the hot and cold water supplies, and check the supply

connections for leakage.

Run water into the whirlpool, and check the drain connections for leakage.

Stud

Nail 1/4" (6 mm)

thick furring strips

through the nailing-in

flange at each stud.

Use #6 large-head

galvanized nails to secure
