Recommended Tools and Materials
Introduction
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
avoid costly mistakes. In addition to proper installation, read all operating and safety instructions.
All information in this manual is based upon the latest product information available at the time of
publication. At Kohler, we constantly strive to improve the quality of our products; we therefore reserve the
right to make changes in product characteristics, packaging, or availability at any time without notice.
Before You Begin
This product is designed for drop-in island installation. Undermount and alcove installations are also
possible.
You must install the bath onto an adequately supported, level subfloor.
Provide properly dimensioned framing.
Choose a fill spout which will provide adequate reach and a minimum 2” (5.1cm) air gap above the
bathing well rim of the unit. You may need to build up the deck material to obtain adequate air space
because the outer rim may be lower than the bathing well rim depending on the specific area of the bath.
Follow local plumbing codes.
The unit must be filled with water through the bathing well, not the overflow channel.
If you plan to install a deck-mounted, hand-held shower, the diverter vacuum breaker must maintain a
minimum 1” (2.5cm) air gap above the outer rim.
When using the K-922 or K-923 Laminar Bath Spout with drip tray K-924, the distance from the finished
wall to the outside wall of overflow channel should not exceed 2” (5.1cm).

3. Construct the Stud Framing
NOTICE: Provide unrestricted service access to the pump, in-line heater and control box. You must
construct an access panel to provide sufficient clearance for servicing the pump, in-line heater, and control
box.
Construct stud framing designed for your particular installation.
Frame the floor, or construct a frame for a raised installation in accordance with the roughing-in
information. When constructing the framing, allow for the thickness of sub and finished deck materials.
Framing should be of 2x4 construction.
Do not support the unit by the rim.
When planning the stud framing, take into account the required 2″(5.1cm) air gap between the end of the
fill spout and the top of the bathing well rim. Take into account the thickness of your planned finished
deck material, and construct the framing and deck material with this minimum air gap in mind.
4. Install the Rough Plumbing
IMPORTANT! Choose a fill spout which will provide a minimum 2″(5.1cm) air gap above the basin rim
of the unit. In addition, if you plan to install a deck-mounted, hand-held shower, the diverter vacuum
breaker must maintain a minimum 1″(2.5cm) air gap above the outer rim of the unit.
NOTE: The listed Kohler spouts are designed to work with this bath at the listed location. There may be
additional spouts that are not listed.
At the locations marked 9–1/2” (24.1cm), the Stillness™ Floor Mount Bath Filler Spout (K-8358), and the
Stillness™ Laminar Ceiling/Wall Mount Faucet (K-923) are appropriate choices.
At the locations marked 7” (17.8cm) and 6–1/2” (16.5cm) the previously listed models apply along with
the Stillness™ Deck-Mount High Flow Bath Faucet (K-954–4), the Finial Deck-Mount High Flow Bath
Faucet (K-T314), the Alterna™ Deck-Mount High Flow Bath Faucet, and the Kallista Barbara Barry
(P22603).
Position the plumbing. Position the fill spout supply so the spout will reach beyond both the outer rim
and the bathing well rim. Water from the fill spout must be directed into the bathing well to fill the
unit. The fill spout must reach beyond the inner edge of the overflow channel.
Cap the supplies, and check for leaks.
5. Prepare the Unit
Carefully lift the unit out of the carton.
Install the drain 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 bath. Be careful not to scratch the
surface of the product.

CAUTION: Risk of product damage. Do not lift or support the unit by the pump or piping.
With help, carefully lift the unit into place.
Cut and discard the banding straps from the pump.
Insert the drain tailpiece into the trap.
7. Install the Plumbing
CAUTION: Risk of property damage. Ensure a watertight seal on the drain connections.
IMPORTANT! Choose a fill spout which will provide adequate air space above the bathing well rim of the
unit. You may need to build up the deck material to obtain adequate air space because the outer rim may
be lower than the bathing well rim. In addition, if you plan to install a deck-mounted, hand-held shower,
the diverter vacuum breaker must maintain a minimum 1″(2.5cm) air gap above the outer rim.
NOTE: An access panel must be installed for future maintenance.
If you have not yet done so, 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.
Make sure all supply connections are tightened securely.

8. Make the Electrical Connections
NOTE: The product model number is printed on a label on the pump side of the unit. This label also
identifies the electrical rating of the product.
WARNING: Risk of electrical shock.Make sure the power has been disconnected before performing
the following procedures. Refer to IMPORTANT INFORMATION section.
CAUTION: Risk of electrical shock. All services must have a Class A Ground-Fault Circuit-Interrupter
(GFCI) which will provide additional protection against line-to-ground shock hazard. A dedicated
service is required for the overflowing bath.
The overflowing bath control and system have been prewired at the factory using 220V hardwire. A
licensed electrician should make a routine service connection to the junction box located on the control
box.
Connect service to the junction box. The junction box contains black and green wires. The grounding
conductor must not be connected to any current-carrying conductor.
Follow local electrical codes.
9. Test Run the Bath
Check the Connections and Fill the Unit
NOTE: The system will purge air at start-up. This is normal.
Check all electrical connections, and make sure the electrical power to the unit is turned on.
Make sure union connections to the pump and in-line heater are securely handtightened.
Make sure the bathing well and overflow channel are clean and free of debris.
Fill the bath as you would a normal bath, 4” (10.2cm) – 6” (15.2cm) from the top, to allow for water
displacement when you enter the bathing well. Water entering the overflow channel will flow into the
drain.
Test the Control Switch
Press the ″On/Off″control switch to start the pump/motor and begin the hydro-therapy cycle. A green
light in the ″On/Off″control switch will turn on to indicate the start of the operating mode. As the
pump/motor turns on and water begins to circulate, the light remain green while the unit is running.
With the unit running, check all harness (piping) connections for leaks.
Visually observe the effervescence rising to the surface of the water.
