Before You Begin

CAUTION: Risk of personal injury or product damage.

Handle with care. Product can break, chip, cause injury or
product damage if handled carelessly. Get help lifting the
sink.

Read these instructions carefully before you begin this
installation.

Observe all local plumbing and building codes.
Shut off the hot and cold water supplies.
Inspect the drain and supply tubing. Replace if necessary.
Prior to installation, unpack the new sink and inspect it for

damage. Return the sink to its protective carton until you are
ready to install it.

Due to the variety of installations possible with this sink, you
may need to use procedures other than those described. Because
of the variety of tiles available, you must take careful
measurements prior to installation.

It is very important that the proper materials are used with your
sink. Proper selection of tile is critical for a secure installation.
Because of the variance in tile thickness, your carpenter, tiler, and
plumber must be aware of the exact type of tile you choose.

After selecting the tile, provide a sample to each contractor
involved in the project. It is very important that the carpenter,
tiler, and plumber maintain communication and discuss the
requirements of the project.

Before You Begin (cont.)

The cabinet and frame shown in these instructions are generic
and may not represent the actual design or structure.

Due to the nature of undercounter installations, Kohler Co.
recommends that undercounter sink installations be performed by
trained and experienced installers.

To ensure a safe and damage-free installation, two people should

install the sink.

All information in these instructions is based on the latest product
information available at the time of publication. Kohler Co.
reserves the right to make revisions in the design of products
without notice, as specified in the Price Book.

1. Preparation

Undercounter Installations

Check to see if the faucet can be completely assembled to the
countertop and the sink.

Determine this by taking the countertop thickness plus the sink
rim thickness, 5/8″ (1.6 cm) plus or minus 1/32″ (1 mm), and
comparing that measurement to the available shank length
between the base of the faucet assembly and the mounting nut. If
the available shank length is the same or longer than needed,
proceed. If not, select a thinner countertop or another faucet.

Tile-In Installations

Tile backer board installed over plywood is the recommended
underlayment for installing this sink. Tile should be bonded to
the backer board with dry set or latex Portland mortar.
Acceptable underlayments include:

•

Tile backer board over 3/4″ (1.9 cm) exterior grade plywood

•

3/4″ (1.9 cm) exterior grade plywood

IMPORTANT! Do not use:

•

Flakeboard

•

Interior grade plywood

•

Gypsum wallboard

2. Cabinet/Support Frame Construction

Measure the size of the sink, including the apron (the bottom of
the apron is approximately 1/8″ (3 mm) wider than the top). The
cabinet opening should equal the maximum sink/apron
dimensions to ensure a minimum gap between the sink and the
cabinet.

NOTE: If the sink is not available at the time of installation, make
allowances to add wood filler strips or spacers to the cabinet
opening after the frame and before the sink is installed.

Determine if the sink will be flush with or extend slightly beyond
the front of the cabinet. The sink may extend no more than 1-1/4″
(3.2 cm) beyond the face of the cabinet.

Construct a wood support frame to fit inside the cabinet opening.
Allow adequate clearance for the water supply lines between the
support and the finished wall.

Locate and cut out the drain outlet clearance hole in the support.
The hole diameter must clear the garbage disposal mounting
system, if used.

3. Support Frame Installation

Tile-In Installations

This sink is designed to be installed flush with or slightly lower
than the surrounding tile. Measure and compare the thickness of
the sink rim and tile. The rim thickness on this sink is 5/8” (1.6
cm) plus or minus 1/32” (1 mm). Take these measurements into
consideration when determining support frame placement
(Dimension “H”). Because of the varying thickness of the tile and
sink, or if adhesive or mortar bed installation is used, you may
need to make allowances to shim the sink, or route the
underlayment as required.

Undercounter and Solid Surface Installations

Position the support frame in the cabinet opening so that when
installed, the top of the sink will be level and flush with the top
of the cabinet (Dimension H).

All Installations

NOTE: Ensure that the securing hardware will not penetrate
through the cabinet walls.

Secure the support frame to the cabinet. Position the securing
hardware to allow for easy removal should the sink need to be
removed or replaced.

CAUTION: Risk of personal injury or product damage.

Large sinks are very heavy. Get help lifting the sink into
place.

Verify that the sink will fit in the cabinet opening. If necessary,
sand the opening or add wood filler strips.

Install the strainer or garbage disposal to the sink according to
the manufacturer’s instruction.

Install the faucet to the sink according to the manufacturer’s
instructions.

Apply a 1” (2.5 cm) spot of sealant at each corner of the frame
where it will contact the sink.

NOTE: If using shims, additional sealant will be needed.

Carefully position the sink within the frame, making sure to
center the sink in the cabinet.

Optional: Apply sealant between the cabinet and the apron.
Verify that the sink is level. Adjust or shim between the sink and

support if needed.
Install the tile. To absorb vibration from a garbage disposal, apply

sealant between the sink and tile directly next to the sink rim.
This will prevent the grout around the sink from cracking.

Allow the sealant to cure for at least 30 minutes before
proceeding.

CAUTION: Risk of personal injury or product damage.

Large sinks are very heavy. Get help lifting the sink into
place.

NOTE: Instructions in this section are for both undercounter and
solid surface installation. Any differences are noted in the text.

NOTE: Use shims to level the sink if needed.

Verify that the sink will fit in the cabinet opening. If necessary,
adjust the opening by sanding the opening or adding wood filler
strips.

For solid surface installation, install the faucet to the sink
according to the manufacturer’s instructions.

Install the strainer or garbage disposal to the sink according to
the manufacturer’s instructions.

Apply a 1″ (2.5 cm) spot of sealant at each corner of the frame
where it will contact the sink.

NOTE: If using shims additional sealant will be needed.

Carefully position the sink within the frame, making sure to
center the sink in the cabinet.

Optional: Apply sealant between the cabinet and the apron.

Undercounter/Solid Surface Preparation (cont.)

Verify that the sink is level. The top of the sink should be flush
with the top of the cabinet to allow proper countertop
installation. Adjust or shim between the sink and support if
needed.

Due to the various cutout sizes possible, a template is not
supplied.

Carefully measure the countertop to determine the exact location
of the cutout.

Carefully mark the cutout location on the countertop.

6. Undercounter/Solid Surface Installation

CAUTION: Risk of personal injury or product damage.

Large sinks are very heavy. Get help lifting the sink into
place.

CAUTION: Risk of product damage. Do not cut, drill, or
sand the countertop while positioned over the fixture.

Both undercounter and solid surface installations are covered in
these instructions. Any differences are noted in the text.

Measure the distance ″Y″ (see illustration) from the finished wall
to the center of the sink faucet holes. This dimension will be used
to locate the faucet hole centerline and the back edge of the
cutout on the countertop. Verify that there is adequate clearance
between the faucet handles and the backsplash or finished wall to
ensure proper faucet operation.

From the back edge of the countertop, measure the same distance
as ″Y″ and draw the faucet centerline. For undercounter
installation, add 1-1/2″ (3.8 cm) to the faucet centerline to locate
the back edge of the cutout. For solid surface installation, subtract
1-1/2″ (3.8 cm) from the faucet centerline to locate the back edge
of the cutout.

Trace the cutout opening onto the countertop using a soft lead
pencil.

For undercounter installation, locate the faucet holes.
Cut out the opening by carefully following the pencil line.
