Waterproofing Material
WARNING: Risk of property damage and concealed leakage. To achieve a watertight installation, it is
critical that you install the waterproofing membrane or applied compound according to the material
manufacturer's instructions. Kohler will not be liable for damage caused by waterproofing materials
that are improperly installed or sealed.
The system produces water flow rates up to 80 gallons (303 L) per minute. It is critical that you
install a waterproofing membrane or applied compound to the entire floor and wall surfaces (up to
the ceiling). You must follow the material manufacturer's instructions to ensure a watertight
installation.
Cement Board
The custom hydro-massage room requires cement board over the entire wall surface from ceiling to
subfloor.
Water-Resistant Wall Material
Plan to install water-resistant wall material on the entire ceiling surface.
Keypad Location
Consider three factors when you choose a location for the keypad. The keypad must be:
• within the Water-Free Zone. User safety and comfort dictate that the keypad be installed and
operated within the room's Water-Free Zone because of the volume and force of the water.
• at the recommended height. We recommend that the keypad be located 58" (147.3cm) to 60"
(152.4cm) above the floor of the basin to maximize usability and comfort.
• within reach of the control box. The keypad uses an 8' (2.4m) cable which cannot be spliced,
extended or stretched.
Finished Wall Material
You may use any waterproof material to finish the walls and ceiling, including ceramic and glass
tile, stone or solid surface material. Various materials have different heat-retaining properties.
