INSTALLATION
1. Finish Frame
A finish frame under the shell rim should always be
constructed to support the bath deck and ensure
proper drainage toward the bath well. This frame is not
intended to support the full bath weight. See
Figures 1
and 2.
Allow ample clearance for any equipment that
may installed on the bath.
CAUTION: Ambient temperature under the bath where
equipment is installed must not exceed 122°F (50°C).
Drop In Framing
The drop in opening should approximately one (1) inch
[2.5cm] less than the outer dimensions of the bath.
Full size templates are included with the bath
packaging for oval tubs.

Alcove Framing
For 3-
wall alcove installations, install a 1”x 2” ledger
strip to support the tile lip flange. See the
Integral Tile
Lip Alcove Installation
section for further instructions.

2. AirMasseur
®
Ventilation (AM baths)
A minimum ventilation opening of 2” x 4” [5x10cm] for
the AirMasseur blower is required. It should be
designed to draw in indoor ambient air at a minimum of
72°F [22°C].
3. Drain and Overflow
Install the drain and overflow assembly to the bath shell
according to the instructions provided with the drain and
position the bath in the area of intended installation.
Finish plumbing rough-in of drain and overflow
assembly. At this time, considerations should be made
for the position and mounting of the faucet set, as well
as all related plumbing.
4. Level Installation
To ensure proper operation, the bath must be leveled
by the rim of the tub. The full length of the bath bottom
should be supported by a mortar bed or other bedding
compound. Spread a 2” [5cm] thick layer of mortar on
the subfloor where the bath will be installed to help
secure, level and support the bath. A plastic sheet
barrier can be placed on top and underneath the mortar
bed.
Set the bath in the mortar bed. Shift the bath from side
to side to settle into the mortar bed. The tub will not
drain properly if the bath is not level both front to back
and side to side. Caution should be taken to prevent
damage to any plumbing or other options when
installing the bath. Let the mortar harden overnight
before use.
Failure to properly bed and install the bath will void any
warranty on the tub shell.
Note:
Do not use isolation pads or a sand bed to install
or level the bath.
