1. Prepare the Site
NOTICE: Refer to the Roughing-in Guide packed with your whirlpool for the required minimum
lb/square foot (kg/square meter) floor support loading.
Make sure the flooring offers adequate support for your whirlpool, and verify that the subfloor is
flat and level.
NOTICE: The whirlpool should be installed in a drop-in, flush, or tiled ledge installation.
Construct 2x4 or 2x6 stud framing designed for your particular installation.
NOTICE: The whirlpool must be supported by its feet or base. Do not support the load weight of the
whirlpool by the perimeter of the rim.
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 Guide for cutout information.
Position the plumbing according to the roughing-in information packed. Cap the supplies, and
check for leaks.

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.
3. Secure the Unit — 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.
Secure the drain tailpiece to the trap. Ensure the whirlpool is level and resting on all support blocks.
Remove the protective tape from the rim. Apply a continuous bead of high-quality silicone sealant
around the entire rim of the whirlpool.
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.
Frame the floor
according to the
roughing-in information.
Position the rough
plumbing.
Construct 2x4 or 2x6
stud framing according
to the roughing-in
information. Verify that the subfloor
offers adequate support,
and is flat and level.

4. Secure the Whirlpool to the Stud Framing
Option for Integral Flange Models
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.
For tile ledge installations, size and install a pressure-treated wood batten along the nailing-in
flange. Pre-drill nail holes through the wood batten and nailing-in flange before securing with
galvanized nails.
Nail 1/4" (6 mm) furring
strips to the studs.

6. Cut the Pump Banding Straps
NOTE: If your pump model does not have banding straps, proceed to the next section.
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.
NOTICE: An access panel will simplify future maintenance.
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.
