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 and a continuous surface, 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 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 all foam feet must make full contact with the leveling ma-
terial. 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 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 installa-
