OSB BOARD INSTALLATION
2a. Cut and trim each piece of OSB board (Left/Right and Rear) according to the chart by model. Mark and
cut out clearance hole for rough plumbing. The OSB is used to provide additional support for the walls
and provide an area to apply adhesive for the wall panels.
2b. Place each piece of OSB board in position according to illustration, keeping it 2” above the shower base
or tub deck and attach into place using screws (self-drill construction screws are recommended, but
standard wood screws can be used). TIP: Mark the location of the top and side of the OSB panels/door
support on the studs to make positioning them easier. NOTE: Ensure screw heads are flat to the OSB
surface and do not protrude.
2c. If installing a shower door, provide additional support using a 1x4" keeping it 1-1/4" (31.8 mm)
off the deck of the shower base or tub and screw into alcove framing. (ref. illustration)
