Tools and Materials
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
encounter any installation or performance problems, please don’t
hesitate to contact us. Our phone numbers and web site are listed on
the back cover. Thanks again for choosing Kohler Company.
Before You Begin
Deep rough-in kit #73444 allows an additional 1/2” (1.3cm) of tile
thickness.
Please read all instructions before you begin.
Observe all local plumbing and building codes.
Before installation, unpack the new faucet and inspect it for damage.
Return the faucet to the carton until you are ready to install.
Leave the protective sleeve on the spout supply tube until the spout
is installed. The spout has an O-ring sealing surface which may be
damaged if unprotected.
Provide an access panel to the valves from under the deck.
Installer-supplied copper tubing is to be 5/8” O.D. (1/2” nominal).
Install water hammer arrestors in the supply lines near the valves.
These instructions cover two methods of installation; installation on
finished deck or rim, and installation on rough (unfinished) deck.
Follow the sections that pertain to your particular installation.

1. Prepare the Site
Install or relocate the water supplies as needed.
Protect the surfaces of the bath/deck during installation.
Ensure that holes drilled into the deck are not oversized. The spout
and valves require adequate base material strength and maximum
contact area with the deck.
Plaster guard diameters are approximately 1–5/8” (4.1cm) for the
valves and 7/8” (2.2cm) for the spout.
NOTE: Reinforcing material may be required if the deck or rim is
thin. Install before proceeding.
NOTE: For installations to be covered with tile, the tile thickness
must not exceed 1–1/4” (3.2cm).

4. Complete Installation on Rough Deck
Set Valve Body Height
NOTE: Use one of the following two formulas to calculate the valve
body clearance required for the finish material at your site.
For tile that is less than 1” (2.5cm) thick, add 1–1/4” (3.2cm) to the
tile thickness. Example: Tile thickness is 3/4” + 1–1/4” = 2” (5cm) of
clearance required.
For tile that is between 1” (2.5cm) and 1–1/4” (3.2cm) thick, add
only 1” (2.5cm) to the tile thickness. Example: Tile thickness is
1–1/4” + 1” = 2–1/4” (5.7cm).
Adjust the threaded collar until the dimension from the top of the
sleeve to the top of the rough deck equals the clearance requirement
needed. Make a note of this dimension. You will use it again after
connecting the supply tube.

Connect Supply Tube
Measure the distance from the bottom of the spout supply tube to
the top of the tee.
Add 1” (2.5cm) to this measurement and cut a piece of copper
tubing to fit into the supply tube and tee port.
Fully loosen the threaded collars but do not remove them.

Complete Installation on Rough Deck (cont.)
Pivot the valve bodies enough to remove the tee and two pieces of
tubing. If the valve body holes are smaller than recommended, it
may be necessary to remove the entire valve body assembly.
Install the tubing into the tee. Match the copper tube from the tee
with the spout supply tube.
Pivot the valve bodies onto the two pieces of copper tubing.
Do not solder at this time.
Reset Valve Body Height
Adjust the threaded collars until the dimension from the top of the
sleeve to the top of the rough deck equals the clearance requirement
calculated earlier.
Solder Connections
Tighten the mounting nuts on each valve body under the deck.
Solder the copper tubes to the valve bodies, tee and spout supply
tube.
Ensure that the cold supply is on the right side.
Solder the hot and cold water supply tubes to the valve body inlets.

the top of the sleeve to the top of the tile. If there is not, correct the
valve clearance as described earlier.
Install tile up to the plaster guards on the valves and the spout
supply tube.
NOTE: The final stem heights for both K-300 and K-301 valves are
1–13/16” (4.6cm) minimum to 2–5/16” (5.9cm) maximum from the
top of the valve to the top of the tile.
1017937-2-A 12 Kohler Co.
7. Install Spout
Wrap a towel around the pipe plug and carefully remove it.
Remove the plaster guard from the spout supply tube.
Cut off the spout supply tube 1–1/4” (3.2cm) above the rim, finished
deck or tile.
Ensure that all burrs are removed from the supply tube.
NOTE: If your installation is on a tile-covered rough deck, slide a
brass washer, flat side facing forward, onto the supply tube. The
brass washer is supplied with the spout. This washer is not needed
for rim/finished deck installations.
Loosen the setscrews in the sleeve. Use a twisting motion to install
the sleeve on the spout supply tube until it contacts the washer.
Align the sleeve so the setscrews are not facing directly forward or
backward and tighten the setscrews.
CAUTION: Risk of product damage. Use care when installing
the spout to prevent damage to the O-ring seal on the sleeve.
Install the spout onto the sleeve and carefully press down until the
spout base contacts the finished deck surface.
Align the spout and tighten the setscrew. If included, press the plug
button into the setscrew hole.

8. Install Handles
NOTE: There are different handle styles available for this product.
Only the sculpted handle is shown. Installation of all handle styles
is identical.
Remove the plaster guards from the hot and cold valves.
Measure the distance from the top of the valve stem to the finished
surface.
For a valve stem height between 1–13/16” (4.6cm) and 2–1/8”
(5.4cm) use a brass spline adapter and screw. For a valve stem
height between 2–1/8” (5.4cm) and 2–5/16” (5.9cm) use a plastic
spline adapter.
If the brass spline adapter is required, attach using the screw
supplied. The plastic spline adapter slides on with no attachment.
Thread the handle onto the valve body. Ensure that the splines in
the handle and spline adapter are engaged.
Position the handle assemblies facing in opposite directions away
from the spout.
Cold
NOTE: The spline adapter allows fine adjustment of the handle
alignment. To adjust, unthread the handle and reposition the spline
adapter. Rethread the handle and check alignment. Repeat until
handle alignment is satisfactory.
