1. Construct the Stud Framing
NOTE: Check the dimensions of the showerhead trim ring if possible. If the diameter of the trim ring
exceeds 2-1/8″(5.4 cm), then mount the shower arm above the shower wall in an appropriate spot.
The showerhead may be installed in the shower wall or above the shower wall. Take into account
the height of the shower users when determining the installation location. The dimensions provided
are for a shower wall installation only.
Construct the framing according to the roughing-in and framing diagrams.
NOTE: If the framing is different from that shown, additional bracing may be required to ensure proper
wall adhesion.
Add any bridging or support needed if you are installing grab bars or towel bars. Refer to the
accessory manufacturer’s instructions.
Add 2x4 bridging between the studs nearest to the front edges of the receptor on each wall at a
center height of 5″(12.7 cm). The receptor nailing flange will attach to the bridging and studs.
Cut a 2x4 ledger board to 34″(86.4 cm) long and cut a second 2x4 ledger board to 32-1/2″(82.6 cm)
long.
The top of the ledger boards should be 4-3/8″(11.1 cm) above the subfloor. Attach the ledger boards
to the studs to provide rim support. Attach the 34″(86.4 cm) board first, then the shorter board so it
butts against the first board.
The plumbing may be installed in the shower wall or above the shower wall. The supplied
dimensions should be used on either wall.
If the unit is installed against a masonry wall, use furring strips to secure the unit. The furring strip
configuration should match the stud configuration shown.

7. Cut the Supply Holes
CAUTION: Risk of product damage. Check and recheck the valve and showerhead locations
before drilling. The hole(s) must be in the correct location.
CAUTION: Risk of injury. Wear safety glasses while cutting or drilling.
Mark the center of the supply valve on the front side of the appropriate shower wall panel. When
determining the valve cutout location, measure the distance from the top ledge of the shower
receptor.
The holes should align with the rough plumbing dimensions from the ″Construct the Stud Framing″
section, and should be on the centerline of the wall panel at the correct distances from the floor.
Refer to the valve manufacturer’s instructions for proper hole size. Ensure the valve cover plate is
large enough to cover the holes.
Drill 1/4″(6 mm) pilot holes at the marked locations on the appropriate shower wall panel.
From the finished surface of the shower wall panel, cut the holes required for the valving. A hole
saw is preferred, but if the correct size is not available it can be cut using a jigsaw with a fine tooth
blade.
Protect the finished surface with masking tape before cutting.
8. Seal the Shower Receptor and Prepare the Stud Wall
IMPORTANT! Follow the sealant manufacturer’s recommended application and drying instructions.

surround.
Sterling 13 1100676-2-F

9. Install the Wall Surround
Install the Shower Wall Panels
Carefully place the shower wall panels directly onto the shower base. Avoid scraping the sealant off
the joint.
Ensure the wall surround is plumb and confirm the shower wall panels are evenly spaced on the
shower base, as this will play a critical role in door alignment.
If the walls are not plumb, attach furring strips to the studs as needed to ensure the wall installation
is plumb. Shim as needed. Repeat until the shower walls are plumb.
If installing the shower wall panels over wallboard, apply adhesive on the wallboard, covering
enough area to provide a secure bond.
Press the wall surround firmly into the corner against the studs or wallboard.
Starting from the outside edge and working toward the corner, secure the wall surround using
drywall screws every 12″(305 mm) to 16″(406 mm) along the nailing flange. Make sure the bottom
of the walls stay in place on the base.
Install the Finished Wall
Install the wallboard with the factory edge (the paperbound edge) a maximum of 1/4″(6 mm)
above the finished, concave surface of the shower wall panels.
Mud, tape, and finish the wallboard.
Finish the surrounding wall. The flange is 1/8″(3 mm) thick.
