Measuring for Ideal Tub/Shower Performance
Installation of this product at non-recommended measurements may
lead to issues such as water discharge from the showerhead during
tub fill mode.
Thin Wall Installation:
(Using the plaster ground to support
the valve)
The thin wall installation method is used
when the tub/shower wall is less than ¼
inches thick (such as a fiberglass tub
surround) and will be the main source of
support for the valve. Installations of this
type require the plaster ground to remain
attached to the valve.
1. Drill a 2-1/4 inch to 3-1/2 inch diameter
hole thru the wall in the location shown
in the installation schematic. This hole
will allow access to the valve but not the
plaster ground.
2. Center the plaster ground / valve
assembly behind the wall opening.
3. Attach the water connections to the valve.
4. Break off the plaster ground cap with a
pair of pliers. Once the trim is installed,
the wall will be "trapped" between the
trim and the plaster ground.
Thick wall Installation:
(Most installations)
The thick wall installation method is used
when the tub/shower wall is greater than
¼ inches thick. Thick walls are usually built
up with materials such as cement board,
drywall, tile etc. The plaster ground will aid
with alignment and can remain attached to
the valve until the valve has been
positioned and secured.
1. Drill a 4-1/2 inch hole in the wall (the
same size as the plaster ground) in the
location shown in the installation
schematic. This hole will help support the
valve during installation and allow access
for future servicing if necessary.
2. Position the plaster ground in the hole so
that its printed face is flush with the
finished wall. This will ensure that the
valve will be at the proper height to
accept the trim.
3. Mechanically secure the valve to the wall
frame members by the use of straps (not
included) or attaching the valve
mounting holes to a cross member
behind the valve through mounting tabs
on the valve.
4. Attach the water connections to the valve.
5. Remove the plaster ground or break off
the plaster ground cap and discard.

Ensure cartridge clip is installed prior to escutcheon installation. For a thin wall installation, the
wall will be "trapped" between the plaster ground and the trim. The plaster ground may be discarded
for thick wall installations. Once the valve is secured in place, remove the escutcheon screws (G). Keep
the escutcheon screws (G) for installation of the escutcheon (F). Place product identification label
(P) on back of escutcheon. Make sure wall is clean, place the escutcheon (F) over the stop tube (B) then
re-install the screws (G). A gasket on the back of the escutcheon provides a seal against the wall.

Shower Only
The center of the valve should be
45 inches to 48 inches above the
shower stall floor. The shower arm
should be placed 78 inchevs above
shower stall floor (recommended
installation of the shower arm is
with a flanged elbow fitting – not
included – and attached to a
wood brace).
Tub/Shower
Position the valve body 32 inches from the floor
of the tub basin. The shower arm should be
placed 78 inches above the floor of the tub basin
(recommended installation of the shower arm is
with a flanged elbow fitting – not included – and
attached to a wood brace). The tub spout is to be
no less than 6 inches and no greater than 11 inch-
es below the valve. If installing a threaded tub
spout, connect to the valve with 1/2 inch pipe or
1/2 inch copper tubing with a threaded adapter.
If installing a slip-fit tub spout, connect to the
valve with only copper tubing – no threaded
adapter is needed.
See step 4.3 for tub spout tube length.

3. Installing Your Valve
Moen has provided a plaster ground attached to the valve
to be used as an installation and alignment guide. The
plaster ground comes attached to the valve in the standard
configuration from the factory. The plaster ground may be
configured in different ways to accommodate various
installation needs and maximize the aesthetic look of the
valve in the shower. The plaster ground may be left in place
until the trim is installed in order to protect the valve from
possible construction damage.
