This bath must be supported along its entire bottom. Use mortar as bedding material (do not use sand or
foam). Apply enough mortar to support the complete bottom of the bath. After the mortar has been poured,
and before it sets, position whirlpool or bath within recess until the rim is leveled against the leveling stringers
(see "Typical Recess Installation") shown above.
The rim of the bath must not support weight. Allow the mortar material to completely harden before
!
applying weight to the rim or bottom of the bath. Any finish material such as tile or wall board must be
self-supporting if it contacts the deck of the bath.
2948LHO/RHO Replace whirlpool and re-shim the integral support feet, shimming the entire length of the
support feet. Secure the shims using construction adhesive, silicone, mortar or equivalent materials. While not
a necessity, the use of a foundation base consisting of cement, mortar, or grout will help provide a solid and
secure installation.
The rim of the bath must not support weight. If foundation base is used, allow the bedding material to
!
completely harden before applying weight to the rim or bottom of the bath. Any finish material such as tile
or wall board must be self-supporting if it contacts the deck of the bath.
