Flooring
NOTICE: Adequate floor support must be provided. Consult the rough-in guide
packed with the bath for specific floor loading requirements.
Install adequate floor support.
NOTICE: To ensure a successful installation, it is critical that the bath be installed on
a level subfloor.
Verify the subfloor is level. Adjust for level, if necessary.
Framing
CAUTION: Risk of property damage. Do not support the bath by the rim. The
bath must be supported by the feet only.
NOTICE: To ensure the bath does not rest on the rim, a 1/16" (2 mm) gap must exist
between the underside of the rim and the framing.
NOTICE: When constructing the framing, take into account the gap and the thickness
of the finished wall/deck material or floor surface. If these factors are not taken into
account, the bath will not fit in the installation area.
NOTE: The illustration above shows a bath with an apron. For baths without an
apron [K-877, K-878]: Construct framing along the entire front side of the bath.
Construct the framing with 2x4 or 2x6 studs for the chosen installation. Refer to
the rough-in guide packed with the bath.
Plumbing
NOTE: For through-the-floor drain installations: A drain hole will need to be cut to
accommodate the drain connections. For above-the-floor drain installations: A hole
will not need to be cut.
NOTE: An access panel is recommended to simplify future maintenance to plumbing.
Position the plumbing according to the rough-in guide packed with the bath.
