Before You Begin (cont.)
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:
Verify 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 Specification Sheet for the
shower column and 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. Verify sufficient clearance under the
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).
IMPORTANT! The shower column connection will not seal
properly if the distance exceeds 2-7/8″(73 mm); see below for the
required deep roughing-in kit.
If the distance is between 2-7/8″(73 mm) and 4″(102 mm):
Order the 1194630 Deep Roughing-in Kit.
If the distance is less than 1-3/8″(35 mm): Order the 1187917

CAUTION: Risk of property damage. Water leakage may
occur if supply piping allows movement. Verify that the

IMPORTANT! Check the existing shower enclosure for adequate
clearances as described in the ″Before You Begin″section.
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. Verify 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 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 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. Verify the upper and
lower mounting-hole locations are level and plumb to one
another.
Do not drill the mounting holes until instructed to do so.
