1. Construct the Stud Framing
Install the drain and supply pipes according to local plumbing codes.
NOTICE: Plan the shower area around the desired placement of the seat. Ensure the placement of the seat
will be free of obstructions (such as pipes or electrical boxes).
Build the shower area out of 2x4 or 2x6 lumber with the centers of the studs 16″(406 mm) apart.
Install the pipes, valves, and showerhead fittings according to the plumbing manufacturer’s
instructions.
If applicable, install a watertight membrane to the floor.
Install the shower basin at this time. Refer to the shower basin manufacturer’s installation
instructions.

2. Reinforce the Stud Pocket
IMPORTANT! Before securing the studs to the framing, confirm that the studs are not warped.
Measure the height of the framing, and cut the studs to that measurement.
Install the studs to the outside of the framing with appropriate fasteners (not provided).
Verify the front surface of the studs are flush. Plane the studs, if necessary.
Attach studs to outside
of determined location
with fasteners.

3. Prepare the Site
Step 1
Wrap and staple water barrier plastic sheeting into the stud pocket.
Place and staple water barrier plastic sheeting over the remaining shower area.
If applicable, install the shower basin at this time.
Step 2
Determine the desired seat height from the finished floor. A seat height of 18″(457 mm) from the
finished floor is recommended.
Verify that this height will not compromise the watertight membrane that may be present in the
floor when fasteners are installed to the bottom flange of the seat. Adjust the height, if necessary.
Position and level the seat unit on the studs with the seat at the desired height. Mark the corners of
the seat unit on the studs, then set the seat aside.
Step 3
IMPORTANT! Select wall material that is water resistant and meets local building codes.
IMPORTANT! A flush transition must exist between the wall material and the attachment flange.
Verify the wall material equals the thickness of the attachment flange, which is 1/4″(6 mm). This
will ensure a flush transition. If a flush transition does not exist, either the studs or attachment
flange must be shimmed before installing the wall material.
Install wall material around the stud pocket, leaving an opening 43-3/8″(1102 mm) in height and
17-1/2″(445 mm) in width for the seat unit.

4. Secure the Unit
Position the unit over the stud pocket.
Thread a fastener (provided) 1″(25 mm) into the mounting hole at the top right corner.
Level the unit, then thread a fastener 1″(25 mm) through the mounting hole at the top left corner.
Alternating from side to side, as shown, partially thread fasteners through the remaining mounting
holes.
CAUTION: Risk of product damage. To avoid cracking the acrylic, do not overtighten the fasteners.
Fully tighten the fasteners, starting at the top and alternating from side to side.
Using 100% silicone sealant, fill in the groove between the attachment flange and the wall material
around the perimeter of the unit. If needed, use a putty knife to press the silicone sealant into the
gap. Wipe off any excess sealant.
Allow the sealant to cure before proceeding.

5. Complete the Installation
Apply mesh tape between the unit and the wall material.
NOTICE: When planning the tile layout, the tile should conceal the installed fasteners on the unit
AND allow for a gap between the edge of the tile and the inner edge of the attachment flange.
TIP: To ensure the first row of tile is level, temporarily level and attach pieces of lumber to the bottom
portion of the wall material at a height less than a full tile. Remove the pieces of lumber once the adhesive
has set, then attach the remaining tile.
Plan the tile installation for the walls, then mark the plan on the wall material.
Attach the tile with tile adhesive or thin-set mortar designed for wet environments.
Allow the tile adhesive or thin-set mortar to cure.
Remove the pieces of lumber from the bottom portion of the wall material.
Apply grout to the tile, except for the expansion joints in the alcove.
Wipe the area with a damp sponge, allow the grout to set, then buff the tile with a soft cloth.
If desired, tape off the area adjacent to the groove where the tile and the acrylic unit meet. This will
help create a straight, uniform bead of silicone sealant.
Apply a bead of silicone sealant, that is color-matched to the grout, in the groove and any other
expansion joints.
Remove the tape once the sealant has cured.
Apply grout sealant to the tile.
Apply mesh tape.
Allow gap between unit and wall
material when installing tile.
Fill gap with
color-matched
silicone sealant.
