Installation Guide

2. Install the Bath
NOTICE: Do not lift the bath by the piping or blower, or use the piping or blower for structural support
of the bath. To avoid damage to the bath, lift by the rim at the sides of the bath.
If the subfloor is not level, shim the bath support blocks or molded supports as necessary.
Option 1: Install Using Construction Adhesive
NOTE: Some models come with support blocks; some models have molded supports.
Apply a generous amount of high-quality construction adhesive to the bottom of the support blocks
or molded supports. With help, carefully lift the bath into position.
Option 2: Using a Cement or Mortar Bed
NOTE: Do not use gypsum cement or drywall compound for this application, as they will not provide an
acceptable, durable bond.
Set the basin area in 1″ (25 mm) to 2″ (51 mm) of mortar cement.
NOTE: The blower must rest directly on the subfloor. The blower should not be in contact with mortar.
Secure the Nailing-in Flanges (Alcove Units)
Drill a small pilot hole through the nailing-in flange at each stud. Add shims as needed.
Use large-head galvanized nails to secure the nailing-in flange to the studs.
Nail furring strips to the studs.
