Installation Guide

Framing Construction (cont.)
Verify that the subfloor is flat and level.
Level the Floor
NOTE: Do not use gypsum cement or drywall compound for this application. They will not provide an
acceptable, durable bond.
The bath supports must rest directly on a level subfloor.
Build a dam that will keep the flooring material in the desired area. Be sure to dam the area for the
drain.
Spread and level a layer of cement or mortar on the subfloor where the whirlpool supports will be
located.
Allow the material to cure.
Remove the dam.
IMPORTANT! Squeaking may develop if the whirlpool is installed over a subfloor other than plywood. In
order to prevent squeaking place a pad between the whirlpool and the 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.
