Thank You For Choosing Kohler Company
We appreciate your commitment to Kohler quality. Please take a few
minutes to review this manual before you start installation. If you

the back cover. Thanks again for choosing Kohler Company.
Before You Begin
CAUTION: Risk of personal injury or product damage. Cast
iron sinks are very heavy. Get help lifting the sink into place.
Observe all local plumbing and building codes.
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.
Inspect the drain and supply tubing. Replace if necessary.
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.
3/8″(1cm) tile is recommended. Because of the variance in tile
thickness, your carpenter, tiler, and plumber must be aware of the
exact type of tile you choose.

Before You Begin (cont.)
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.
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 proper sink fit in the cabinet and support frame, Kohler
recommends providing the cabinet maker with the actual sink to
be installed.
To ensure a safe and damage-free installation, two people should
install the sink.
Do not use adhesives or adhesive sealants with this product.

1. Preparation
Install the water supplies and drain piping according to the
roughing-in information.
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, 3/8” (1cm) plus or minus 1/32″(1mm), 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″(1.9cm) exterior grade plywood
•3/4″(1.9cm) exterior grade plywood
IMPORTANT! Do not use:
•Flakeboard
•Interior grade plywood
•Gypsum wallboard

used.

2. Cabinet/Support Frame Construction
CAUTION: Risk of personal injury or product damage. The
wood support and frame for the sink must sufficiently support
300 lbs. (136 kg) (approximate weight of the cast iron sink when
full and a garbage disposal installed).
Measure the size of the sink, including the apron. 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 1/2”
(1.3cm) beyond the face of the cabinet.
Construct a wood support frame to fit inside the cabinet opening.
Allow adequate clearance for the faucet assemblies and the sink
basin.

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 3/8” (1cm)
plus or minus 1/32” (1mm). 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.

4. Tile-In Installation
CAUTION: Risk of personal injury or product damage. Cast
iron 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” (2.5cm) 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.

5. Undercounter/Solid Surface Preparation
CAUTION: Risk of personal injury or product damage. Cast
iron 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.
Verify that the sink will fit in the cabinet opening. If necessary,
sand the opening or add 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” (2.5cm) 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. 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 cut-out sizes possible, a template is not
supplied. If using the K-5984 cutting board, the minimum cut-out
length is 31″(78.7cm).
