DESIGN GUIDE
FOOTBATH BASIN
Design a mortar bed footbath basin using typical shower basin fabrication methods and materials. Carefully study the following factors while designing your Custom BodySpa footbath basin.
Basin size and shape:We recommend a room size approximately 07inches long x 47inches wide x 47inches high for the Custom BodySpa installation. The basin design must provide for a water depth of at least 37inches above the top of the suction cover. The threshold of the basin should be to 77inches above the top of the suction cover. Next, locate the drain overflow so it will produce a minimum water depth 37inches above the top of the suction cover. Design the basin framing to provide an overall basin water capacity between 0
and 200 gallons. Study the Surface Area chart on Page NOTAG.
The size of the basin will affect the amount of hot water needed each time the user fills the Custom BodySpa footbath basin.
Ledges, seats, shelves, and steps are all excellent ideas to enhance the character and functionality of the Custom BodySpa installation, but remember that these things may also slow down the return of water to the basin. This in turn may demand that the user add more water to fill the footbath basin before use.
Floor pitch:Incorporate a finished floor
pitch of 1/4 to 1/27inch per foot toward the drain to provide a safe, efficient water drainage surface.
Finished floor material:The finished
floor material must be slip7resistant tile or stone to reduce the potential for slipping accidents.
Bear in mind that various materials offer different heat7retaining properties.
Desired drain location:The drain
location should be no more than 47inches from the drain overflow ell. Design the footbath basin so the combined thickness of the subfloor, cement board, waterproofing material, mortar bed, and finished material does not exceed 171/27inches at the drain if the K7717 Drain will be used.
For the K7717 Drain, the combined basin wall thickness must be between 3/4 and 173/47inches where the drain overflow will be installed.
Suction location: The center of the suction cover must be located between 271/2 and 371/27inches up from the finished floor surface.
