TOSCA THERMOSTATIC SHOWER SET INSTALLATION
GETTING STARTED
BEFORE YOU BEGIN
We recommend consulting a professional if you are
unfamiliar with installing plumbing fixtures. Signature
Hardware accepts no liability for any damage to the
plumbing, floor, walls, tub, or for personal injury during
installation.
Observe all local plumbing and building codes.
Unpack and inspect the faucet for shipping damage. If
any damage is found, contact our Customer Relations
team at 1-866-855-2284.
Ensure that you have gathered all the required
materials that are needed for the installation.
For the following installation instructions, it is
assumed that the wall has been opened and that the
existing shower set has been removed.
Before you begin, the main water supply to your home
should be shut off.

Step 1: Valve Installation
3. Route, assemble, and connect all in-wall piping as
desired to and from the shower valve. Make all connec-
tions appropriately depending upon the type of pipe
that is being used. For copper pipe, soldering will be
required and should be completed by a licensed
plumber. Apply plumber’s tape to any threaded connec-
tions if applicable. Install any wood blocking that is
necessary to support the piping and valve.
Important Notes:
A) The valve has two single-function outlets, one exiting
left and the other exiting right. The plumbing for the
hand shower will connect to one outlet, and the plumb-
ing for the shower head will connect to the other.
B) Female fittings will need to be placed where the hand
shower’s supply elbow will attach, as well as where the
shower arm will attach. The fittings should sit no more
than ¼” behind the finished wall.
1. To prepare for installation, wood blocking should be
installed between the two studs where the valve will
mount. The wood blocking will need to be installed 2
¼”-2 ¾” behind the finished wall.
Important: Take into consideration the thickness of
the finished wall materials, such as tile, when calculating
measurements.
2. Secure the valve to the prepared wood blocking
using the provided hardware. Ensure that the “cold”
inlet is pointing down, and the “hot” inlet is pointing up.
Use a level to ensure that the valve is straight and
level.
Tip: Leave the protective sleeves on the valve stems
until your finished wall is complete, and you are ready
to install the trim pieces.

1. Once the finished wall is complete, remove the
protective sleeves from the valve stems. If the test plug
has not yet been removed, remove that as well.
2. Slide the decorative back plate onto the valve. Ensure
that the markings located above each opening on the
back plate are facing up.
4. Once all piping is routed and connections have been
made, use a ½” test plug to perform a water pressure
test. Turn on the main water supply to your home and
water test the installed plumbing. Ensure that there are
no leaks, then shut the water off. Remove the test plug.
Note: Water pressure testing should be performed by
a licensed plumber if you are not familiar with this
procedure.

5. To install the temperature control knob, slide the
knob onto the center valve stem. Use the provided
screw to attach, and tighten with a Phillip’s screwdriver.
Insert the decorative screw cover to conceal the screw.
6. To install the hand shower’s water supply elbow,
thread it onto its prepared female fitting. Apply thread
sealant or plumber’s tape to the threads before
tightening. Use the decorative escutcheon to conceal
the rough-in.
3. Disassemble the left and right control knobs to
prepare for install. Untwist the lever from each knob,
then remove the threaded posts from each.
4. Slide the knobs onto the left and right spindles. Use
the threaded mounting posts to secure the knobs to
the spindles. Tighten the posts using the provided hex
wrench, then reattach the levers by threading them
onto the posts.

9. Attach the hand shower to the supply elbow using the
hand shower hose. Apply thread sealant or plumber’s
tape to the threads before tightening. Hand tighten the
connections firmly.
10. Attach the shower head arm by threading it into its
prepared female fitting. Be sure the use the decorative
escutcheon to conceal the rough-in. Apply thread
sealant or plumber’s tape to the threads before
tightening.
7. Determine a location to mount the hand shower’s
slide bar. Temporarily install the mounting brackets
onto the bar, and hold the bar against the wall at the
desired mounting location. Use a level to ensure that
the slide bar is straight, then mark the locations of the
mounting brackets by outlining them with a pencil.
Remove the bar, then attach the brackets to the wall
using the provided anchors and screws.
Important: If drilling through tile, you must use a
masonry drill bit and drill carefully.
8. Once the mounting brackets are attached to the
wall, attach the slide bar by mounting it onto the
brackets. To secure, tighten the set screws located on
the slide bar using the provided hex wrench.

completed shower system. Ensure that there are no
leaks and that all functions are working properly.

head to the installed shower arm. Apply thread sealant
or plumber’s tape to the threads before tightening.
