2 WALL BASE INSTALLATION
PRELIMINARY
The floor structure beneath the unit must be able to support a total weight of the unit and bather. Refer to the table under total weight.
STEP 1
Provide an opening in the subfloor no less than 5" x 5" square. This opening should be located on the center lines of the shower base drain hole (See Product Chart). The opening is to accommodate a 2" waste pipe. The waste pipe should be 1/4" to 1/2" above the surface of the subfloor.

Remove excess sealant from finished side.
Apply a lubricant (common household liquid soap works well) to the inside of the rubber seal of the drain assembly.

DEATAIL 1
If the subfloor is level, no other preparation is neces- sary. You can proceed to install the shower base. If the subfloor is not level, level shower base by spreading floor leveling compound, mortar, plaster or minimal expansion structural foam with a minimum density of 5 lbs./cubic feet EVENLY over ENTIRE area where base will be installed. The compound used MUST make contact with the entire bottom surface of the base. Both sides of a joint or splice of subfloor should be level to each other. Level and support waste pipe cutout area greater than 5" x 5". The base is NOT to be supported by the tile flange.
SPREAD MORTAR OR LEVELING COMPOUND ETC. EVENLY OVER ENTIRE AREA
