Construct 2x4 or 2x6
stud framing according
to the roughing-in
information.
Provide a 1/16" (2 mm) gap
between the bath rim and
framing.
Drop-In Installation
2. Construct the Drop-In/Island Framing
The bath may be installed in either a drop-in or an island installation.
A drop-in installation requires a cut-out in the floor with decking on all four sides. A framework and
subfloor must be added below the deck. The deck positions the bath while the framework and subfloor
support the bath.
An island installation requires a built-up, four-sided surround typically made of brick or concrete. The floor
that the built-up surround rests on supports the bath. The surround only positions the bath.
NOTE: Be sure to provide adequate floor support. The water capacity for the bath is 56 gallons (212 liters)
of water.
For Drop-in Installations
CAUTION: Risk of product damage. Do not support the bath by the rim.
Carefully lay out and cut the rough deck material. Use the cut-out template, if one is provided, or
refer to the applicable diagram in the "Roughing-In" section.
Allow clearance to install the drain assembly and the water supply piping.
Construct an access panel at the plumbing end of the fixture.
NOTE: The subfloor must be no lower than 16-1/2" (41.9 cm) below the deck. The subfloor installation
should allow 1/16" (2 mm) of clearance for sealant between the deck and the lower rim of the empty bath.
Construct a 2x4 or 2x6 frame with plywood subfloor below the deck.
Make sure the subfloor is flat and level.
For Island Installations
CAUTION: Risk of product damage. Do not support the bath by the rim.
Carefully lay out the masonry work. Consider whether the finished tile will be flush with the bath
or installed under the rim.
Make sure that the subfloor is flat and level.
Allow clearance to install the drain assembly and the water supply piping.
Construct an access panel at the plumbing end of the fixture.
