OSB BOARD INSTALLATION
2a.
Cut and trim each piece of OSB board (Left and Right) according to the roughin above for the model in-
stalled. 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
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 1x3" keeping it 1-1/4" (31.8 mm) off the deck
of the shower base and screw into corner framing. Chamfer outer edges if necessary. (ref. illustration)
