6. Prepare the Site - Recessed and Island Installations
NOTICE:
Do not support the whirlpool by the rim.
Recessed Installation
NOTE:
A recessed installation requires a cutout in the floor with decking on all four sides. A framework
and subfloor must be added below the deck. The deck positions the whirlpool while the framework and
subfloor support the whirlpool.
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 18
″
(457 mm) x 15
″
(381 mm) access panel at the pump end of the fixture.
NOTE:
The subfloor must be no lower than 18-3/4
″
(476 mm) below the rough deck. The subfloor
installation should allow 1/16
″
(2 mm) clearance for sealant between the rough deck and the lower rim of
the empty whirlpool.
Construct 2x4 or 2x6 framework and a level subfloor.
Island Installation
NOTE:
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 whirlpool. The surround only positions the
whirlpool.
Carefully lay out the masonry work. Consider whether the finished tile will be flush with the
whirlpool 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 18
″
(457 mm) x 15
″
(381 mm) access panel at the pump end of the fixture.
NOTE:
The subfloor must be no lower than 18-3/4
″
(476 mm) below the masonry island. The subfloor
installation should allow 1/16
″
(2 mm) clearance for sealant between the island and the lower rim of the
empty whirlpool.
Construct the island of brick or concrete.
Add tile or other finishing material, leaving a 1/16
″
(2 mm) clearance for sealant between the island
and the rim of the whirlpool.
Island Installation
Construct opening to be 1" (25 mm)
smaller than the bath in both directions.
Construct according to the
roughing-in illustration.
