GENERAL INSTALLATION GUIDELINES (continued from previous page)
PRE-LEVELED FRAME
Place tub into proper location and attach to floor with 2" screws drilled through frame. This system does
not require bedding compound unless subfloor is not level. A self leveling compound can be used to level
the subfloor. Read and follow all manufacturers directions.The pre-leveled frame adds approximately 2"-3"
to the height of the bath.
WOOD SKIRT
Paint front and back of skirt to seal wood before attempting installation. Secure to floor cleat and wall
supports using 4d finish nails. Paint as desired.
TILE FLANGE – FACTORY INSTALLED
1. Mark flange of tub where it aligns with wall studs
2. Pre-drill a minimum of three holes on each side
of the tub flange to align with selected wall studs.
Place enough bedding compound (MTI recommends
Quickrete Sand Mix) to fill void between the
bottom of the tub and floor. If your tub was ordered
with the pre-leveled foam option, no bedding
compound is necessary. Note: If your floor is not
completely level, use enough bedding compound to
achieve level.
3. Work tub into bedding compound.
4. Ensure that tub is level, both front to back and side to side.
5. Attach tub to wall studs using the pre-drilled holes in the flange.
6. Fill the void between the tile flange and tub with clear silicone.
TILE FLANGE KIT – FIELD INSTALLATION
1. Clean tub flange.
2. Apply supplied adhesive to tub flange and tile flange with
brush, being careful not to get adhesive on top of tub.
3. Position tub 2-3" from wall.
4. Apply tile flange to tub flange.
5. Position the tub against the walls. Adhesive will set in
minutes.
6. Seal / fill the void between the tile flange and tub with clear
silicone.
