Before You Begin

NOTICE: Risk of personal injury. Handle the bath and frame carefully. Some edges may be sharp or

rough.

NOTICE: Risk of product damage. Handle the bath and frame carefully. The bath will break or

malfunction if handled carelessly.

NOTICE: Risk of product damage. Do not support the weight of the bath by the perimeter of the rim. To

avoid damage to the product, support the bath by its base or feet.

NOTICE: Risk of product damage and personal injury. Due to the weight and installation difficulty of

the product, Kohler Co. recommends that two people perform this installation. There are several

installation sequences that are very difficult if performed alone.

IMPORTANT! Use care when removing screws. All screws will be reused unless otherwise indicated. Do

not strip the heads.

IMPORTANT! Do not cut or remove any cable ties unless instructed. They are used to hold critical parts

in place, and are designed to stay in place throughout the installation.

IMPORTANT! If the installation site is in an area where frequent or prolonged power outages occur,

Kohler Co. recommends that a minimum 350 VA Uninterruptible Power Supply (UPS) be installed as a

backup power source to the bath controller. The UPS will ensure that door functionality is not

compromised in the event of a power outage.

Follow all local plumbing and electrical codes.

Depending on the installation, it may be necessary to disassemble parts of the bath to pass

through all doorways, hallways, and stairways between the staging area and the bathroom. There

will be several points in this installation where the installer will be asked if further disassembly

is required. All adjustments have been made at the factory. Installation time is less for jobs

requiring little or no disassembly.

IMPORTANT! Save all hardware. If disassembly is required, save and organize all hardware. Hardware

will be reused unless otherwise speciﬁed.

There are supplemental installation instructions located on the back of the access panel.

This bath requires three drains with separate P-traps. Allow for three drains connecting at the

stack in your installation.

The installation instructions outline the only parts that need to be removed or disassembled during

the installation process. Although many parts may appear to be removable, do not disassemble

anything unless instructed.

Unpack the bath in an open area.

Inspect the unit for damage and make sure parts such as counterweights, access panel, and trim

caps are accounted for. The unit shown in this manual has a left-hand drain and may appear

different than the unit you have purchased.

1. Construct the Framing

All Installations

NOTICE: Measure your product for site preparation. Note the model number located on the blower

motor, then visit the product page at www.kohler.com for more information.

NOTICE: Adequate ﬂoor support must be provided.

NOTICE: Do not support the weight of the bath by the perimeter of the rim. To avoid damage to the

product, support the bath by its base or feet.

IMPORTANT! This product requires three 1-1/2″diameter drain outlets, three P-traps, and three separate

lines to the stack. In an ideal conﬁguration, none of the drains should be combined, as performance may

suffer and the potential for backﬂow will increase. If required, the two bathing vessel drains (#1 and #2 in

diagram) may be combined downstream from the P-traps into a single 3″diameter drain line.

IMPORTANT! The drain for the receptor tray (#3) requires a dedicated P-trap and stack connection.

Follow all local plumbing and electrical codes.

Leave the stud pocket open and do not install the ﬁnished wall until after the bath has been

installed. This installation is best done with access from the backside of the studs, particularly from

each side.

NOTICE: Follow all local plumbing and electrical codes.

If the installation site is in an area where frequent or prolonged power outages occur, Kohler Co.

recommends that a minimum 350 VA Uninteruptable Power Source (UPS) be installed as a backup

power source for the bath controller. This will ensure the door will open in the event of a power

outage.

Construct 2x4 or 2x6 stud

framing according to

the roughing-in information.

Position the rough plumbing.

Verify that the subfloor offers adequate support, and is flat and level.

Construct the Framing (cont.)

Install a 120 V, 15 A, 60 Hz electrical outlet protected by a GFCI or RCD. The outlet must be located

on the side of the bath opposite the footwell drain outlet, within 24″(610 mm) of the controller).

Units with the heated surface feature will require a second electrical outlet within 24″(610 mm) of

the heated surface controller.

NOTE: Drain #1 is the sidewall drain/valve outlet. Drain #2 is the overﬂow and footwell drain outlet.

Drain #3 is the receptor tray drain outlet.

NOTE: Three drains are required for this product. Drains #1 and #2 require a 10″(254 mm) x 10″(254

mm) cutout.

NOTE: Drain #3, the receptor tray drain, requires a 10″(254 mm) x 10″(254 mm) cutout if access from

below is available. If above-the ﬂoor access is required to make the connections, a 10″(254 mm) x 16″(406

mm) cutout is required to allow access. The 10″(254 mm) wide cutout is critical to prevent subﬂoor

contact with the drain area of the receptor tray. If the subﬂoor and drain come into contact, enlarge the

cutout as needed or raise the bath using the adjustable feet. The receptor tray must be level and the drain

must rest comfortably through the subﬂoor.

Make sure the ﬂooring offers adequate support for the bath, and verify that the subﬂoor is ﬂat and

level.

The bath should be installed in an alcove installation. Construct a 2x4 or 2x6 frame.

Position the plumbing. Cap the supplies, and check for leaks.

Provide adequate ventilation and at least 15 cubic feet (.4 cubic meters) of open air space for cooling

the motor and supplying sufficient air to the blower. Do not install the blower motor closer than 1″

(25 mm) to the wall or other objects.

IMPORTANT! Use the chart below as a general guideline. Every installation varies. Hallways, corners,

stairways and other obstacles should be taken into account when determining how much disassembly is

required. Avoid unnecessary disassembly when possible.

Door Opening Recommended Installation Action

Larger than 33″(838 mm) No disassembly is required. Skip sections 4

through 8.

31″(787 mm) to 33″(838 mm) Remove the door from the bath and the

receptor from the support frame.

30″(762 mm) to 31″(787 mm) Full disassembly is likely. Follow all steps in

this manual.

Less than 30″(762 mm) The door open needs to be enlarged to a

minimum of 31″(762 mm).

2. Conﬁrm the Correct Cutout

All Installations

NOTE: Drain #3, the receptor tray drain, requires a 10″(254 mm) x 10″(254 mm) cutout if access from

below is available. If above-the ﬂoor access is required to make the connections, a 10″(254 mm) x 16″(406

mm) cutout is required to allow access. The 10″(254 mm) wide cutout is critical to prevent subﬂoor

contact with the drain area of the receptor tray. If the subﬂoor and drain come into contact, enlarge the

cutout as needed or raise the bath using the adjustable feet. The receptor tray must be level and the drain

must rest comfortably through the subﬂoor.

Measure the cutout to conﬁrm it is a minimum of 10″(254 mm) wide and 16″(406 mm) long.

Study the illustrations at the right. When the cutout is the correct size, the drain outlet on the

receptor tray and the surrounding material will not come in contact with the subﬂoor. The drain

outlet will protrude into the cutout when installed.

If the cutout is too small, the receptor tray will be too high. The counterweights will strike the

receptor tray when the door is raised and the door seals will not inﬂate.

3. Install the Drain Lines and Rough Plumbing

All Installations

Plumbing Access Considerations

Conﬁrm adequate mounting and connection space exists for the faucet speciﬁed for your

installation.

Conﬁrm adequate clearance for three P-traps.

If the unit is installed on a slab at a corner of the outside walls: Make connections to the

accessible end, or provide access to the plumbing connections if not able to do so through the front

access panel. Check the P-trap clearance for drains #1 and #2.

If the unit is installed on a slab back-to-back against the outside walls: Plan to provide adequate

access to the plumbing connections. Limited access is available through the access panel. Check the

P-trap clearance for drains #1 and #2.

When the unit is installed where the drain connections are accessible from below: Connections

can usually be made from underneath the unit.

Install the Rough Plumbing

IMPORTANT! This product requires three 1-1/2″diameter drain outlets, three P-traps, and three separate

lines to the stack. In an ideal conﬁguration, none of the drains should be combined, as performance may

suffer and the potential for backﬂow will increase. If desired, the two bathing vessel drains (#1 and #2)

may be combined downstream from the P-traps into a single 3″or larger drain line.

Install the plumbing lines following the valve and trim manufacturer’s instructions. Recommended

supply ﬁttings and locations are shown above.

Use 3/4″valves for optimal ﬁll time.
