Tools and Materials
Before You Begin
NOTE: This guide includes the installation sequence for the shower
column only. Install the mixing valve, mixing valve trim, and spout
according to the manufacturer’s instructions.
NOTICE: Risk of product damage. Do not apply excessive weight
or downward force to the shower column.
CAUTION: Risk of property damage. Water leakage may
occur if supply piping allows movement. Ensure the supply
piping and 1/2″-14 NPT elbow fitting are securely fastened to
braces in the stud framing.
Please read all instructions before you begin.
Observe all local plumbing and building codes.
Shut off the water supply.
Inspect the existing supply piping and wall materials. Replace if
necessary.
The shower column is supplied with toggle anchor fasteners for
installation onto a finished wall surface. The finished wall
thickness must be a minimum of 5/8″ (16 mm) and must be
adequate in strength. Two toggle anchor fasteners are required
per mounting collar.
IMPORTANT! If the supplied toggle anchor fasteners are not used
to install the shower column:

Before You Begin (cont.)
Ensure that adequate strength wall backing materials and stud
bracing are properly positioned behind the finished wall.
Obtain proper fasteners (not provided) taking into account the
type of stud bracing material and thickness of the mounting
collar, finished wall, wall backing, and stud bracing.
Fasteners must be corrosion-resistant and capable of 300 lbs (136
kg) load bearing per fastener.
A minimum of two fasteners are required per mounting collar.
Fasteners must be securely anchored into the stud bracing to
adequately support the product.
IMPORTANT! For retrofit/remodel installations: Check the existing
shower enclosure for adequate clearances before proceeding with the
shower column installation. Refer to the Roughing-in for the shower
column and Rain showerhead.
Verify the distances between:
•
The ceiling and the center of the existing shower arm at the
finished wall surface.
•
The shower floor and the center of the existing shower arm at the
finished wall surface. Ensure sufficient clearance under the Rain
showerhead.
•
The center of the existing shower arm and the center of the
mixing valve trim.

Roughing-In - Upper Supply Connection
Measure the distance between the 1/2″-14 NPT elbow and the
finished wall surface. The distance must be between 1-3/8″ (35
mm) and 2-7/8″ (73 mm). The shower column connection will not
seal properly if the distance exceeds 2-7/8″ (73 mm).

1. Retrofit/Remodel Installation
CAUTION: Risk of property damage. Water leakage may
occur if supply piping allows movement. Ensure the supply
piping and 1/2″-14 NPT elbow fitting are securely fastened to
braces in the stud framing.
IMPORTANT! Check the existing shower enclosure for adequate
clearances as described in section ″Before You Begin.″
Remove the existing showerhead and shower arm escutcheon.
Carefully push the existing shower arm toward the finished wall
surface.
Check for inward movement of the supply piping.
If inward movement is possible, securely fasten the supply piping
to braces in the stud framing before beginning the shower column
installation.
Remove the existing shower arm.
Measure the existing shower arm hole. Ensure that the finished
wall material has an upper supply connection hole diameter
between 1″ (25 mm) minimum and 1-1/4″ (32 mm) maximum,
and the hole is centered on the outlet of the 1/2″-14 NPT elbow
fitting. Repair the wall surfaces if the existing shower arm hole is
not centered or exceeds the recommended dimensions.

3. Mark the Mounting Hole Locations
NOTE: The upper mounting collar must be centered on the supply
adapter. The distance between the upper and lower mounting collar
centers should be 18″ (457 mm) or 27″ (686 mm) depending on the
length of your shower column.
Center the mounting collar on the supply adapter. Mark the left
and right mounting holes.
For K-45209/K-45210/K-45386/K-45387 only: From the center of
the supply adapter, measure down 27″ (686 mm) and mark the
horizontal measurement with a pencil.
For K-45211/K-45212/K-45388/K-45389 only: From the center of
the supply adapter, measure down 18″ (457 mm) and mark the
horizontal measurement with a pencil.
Center the mounting collar on the horizontal line. Measure and
mark the left and right mounting holes. Ensure the upper and
lower mounting hole locations are level and plumb to one
another.
Do not drill mounting holes until instructed to do so.

Carefully slide an escutcheon onto the upper connection
assembly.
Thread a mounting collar onto the upper connection assembly.
Repeat steps for the lower mounting collar and escutcheon.
Carefully slide the shower column onto the supply adapter.
Ensure the lower mounting collar is tight against the finished
wall.
Proceed to section ″Plumb the Shower Column.″
Kohler Co. 11 1184491-2-A
5. Plumb the Shower Column
Using a level, check the position of the shower column to ensure
it is plumb.
The upper mounting collar is adjustable to account for level and
wall surface offset. Turn the mounting collar until the shower
column is plumb.
Verify that the mounting collar slots align with the pencil
markings on the finished wall. Make any adjustments as needed.
Remove the shower column from the supply adapter.
Verify mounting
holes align with
marked locations.
Adjust for
level.

6. Install with Anchors
IMPORTANT! If the supplied toggle anchor fasteners are not used,
refer to section ″Before You Begin″ for fastener requirements.
NOTE: Anchor installation requires 1-7/8″ (48 mm) minimum
clearance behind the wall. The finished wall thickness must be a
minimum of 5/8″ (16 mm) and must be adequate in strength.
Install the Anchors
Drill two 1/2″ (13 mm) diameter holes for each mounting collar
at the pencil markings on the finished wall.
Hold the metal channel of the anchor flat alongside the plastic
straps and slide the channel through the drilled holes.
Realign the handles of the straps to straighten the channel behind
the wall.
With one hand, pull the finger grips straight out (do not pull at
an angle) so that the metal channel rests flush behind the wall.
Slide the clip along the straps with your other hand until the
flange of the clip is flush with the wall.
Drill 1/2" (13 mm)
holes at each
marked location.

9. Install the Handshower
NOTE: Elbow installation is optional and allows the hose to drape
around the mixing valve trim. The shower hose can also be installed
directly onto the shower column if desired.
With gasket installed, thread the elbow onto the bottom of the
shower column.
With gasket installed, thread the check valve end of the shower
hose to the elbow.
Position the handshower holder and the elbow opposite each
other. This allows the hose to drape around the mixing valve
trim.
Thread the hose through the holder.
With screen washer installed, thread the hose to the handshower.
Place the handshower into the holder.
