Roughing-In Illustrations (cont.)
If installing this bath with a shower door, refer to the shower door manufacturer’s instructions for any
special framing considerations.
1. Framing Construction
Install the Framing
NOTE:
Refer to the
″
Roughing-In
″
section for dimensions.
Install the subfloor if needed.
For installations with wall surrounds, ensure that the outer stud is aligned with the vertical wall
flanges at 30
″
(76.2 cm) from the back wall. The outer stud edge should align with the wall flange
edge.
Construct 2x4 stud framing for your particular installation according to the
″
Roughing-In
″
section.
Ensure that the framing for each stud is plumb and square to within 1/8
″
(3 mm). Shim as needed
to meet tolerances.
For baths with above-the-floor drains, ensure that the drain piping can pass through the wall, and
that the wall’s load bearing requirements are satisfied. Modify the framing or raise the subfloor as
needed to obtain clearance.
Install the Accessories
IMPORTANT!
For installations with wall surrounds, do not install accessories that require backing or
support. Such installation could void the warranty.
IMPORTANT!
For installations with wall surrounds, do not allow fiber or other soft insulation to drop
down into the back channel, as this could damage the bath.
For installations with wall surrounds, cover or seal any loose material.
For bath only installations, provide the necessary backing or support for shelving, grab bars, towel
bars or other accessories. Refer to the accessory manufacturer’s instructions.
Construct the Floor
IMPORTANT!
Construct the floor of plywood. If the bath is installed over material other than plywood,
friction may cause squeaking over time.
IMPORTANT!
Make sure the felt pad is properly positioned so that every bath-subfloor contact point has
felt between the bath and the subfloor.
Place the provided felt pad between the bath and the subfloor, positioned so that every
bath-subfloor contact point has felt between the bath and the subfloor.
For baths with through-the-floor drains, cut a hole in the floor for the drain line.
Verify that the subfloor is flat and level. If the subfloor is not level, proceed to the
″
Level the Floor
″
subsection.
IMPORTANT!
Squeaking may develop if the bath is installed over a subfloor other than plywood. In
order to prevent squeaking place a pad between the bath and subfloor. The recommended pad material is
a spun bonded polyester landscape fabric, or spun bonded house wrap material. Do not use roofing felt
for this purpose.
Level the Floor (If Needed)
NOTE:
Use cement or mortar for this application. Gypsum cement or drywall compound will not provide
adequate support.
