Framing and Support
The drain/overflow of the bath extends below the bottom of the bath. Note that this requires a cutout in the floor.
The floor structure beneath the bath must be able to support a total weight of bath, water, and bather.
Refer to the table under total weight for your model. The unit must be supported from the bottom of the bath and
not from the bath rim or tile flange. If the subfloor is level, no other preparation is necessary. You can proceed to
install the bath. If the subfloor is not level, you MUST level the entire surface prior to installing the bath. The use of
materials that shim or provide a level installation are allowed provided the method used will insure a level bath that
is supported from the bottom. Materials that may be used are a floor leveling compound, mortar, plaster or minimal
expansion structural foam having a density of a minimum of 5 lbs./cubic ft.; however the bath must remain level in
order for it to drain properly and the foam feet must make full contact with the leveling material. Both sides of a joint
or splice of subfloor should be level to each other. When attaching baths with flanges to stud wall, use shims to
fill any gaps between the bath flange and studs.
The rim of the bath is not designed to support weight. If finish material is to overlap or contact the bath, the added
weight must be fully self-supporting.
The protective film liner inside the bath is used to prevent damage to the finish from shoes, tools, etc.
during installation. Before installation, remove liner to inspect for any defects, reapply and do not remove
until final cleanup.
Important: If a skirt is to be used, it must be installed at the time of unit installation – refer to skirt
installation instructions. Install optional trim parts when all installation has been completed.
