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.
S Basin size and shape: We recommend a
room size approximately 60Ćinches long x
48Ćinches wide x 84Ćinches high for the
Custom BodySpa installation. The basin
design must provide for a water depth of at
least 3Ćinches above the top of the suction
cover. The threshold of the basin should be
6 to 7Ćinches above the top of the suction
cover. Next, locate the drain overflow so it
will produce a minimum water depth
3Ćinches above the top of the suction cover.
Design the basin framing to provide an
overall basin water capacity between 90
and 200 gallons. Study the Surface Area
chart on Page NO TAG.
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.
S Floor pitch: Incorporate a finished floor
pitch of 1/4 to 1/2Ćinch per foot toward the
drain to provide a safe, efficient water
drainage surface.
S Finished floor material: The finished
floor material must be slipĆresistant tile or
stone to reduce the potential for slipping
accidents.
Bear in mind that various materials offer
different heatĆretaining properties.
S Desired drain location: The drain
location should be no more than 48Ćinches
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 1Ć1/2Ćinches at the drain if
the KĆ7179 Drain will be used.
For the KĆ7179 Drain, the combined basin
wall thickness must be between 3/4 and
1Ć3/4Ćinches where the drain overflow will
be installed.
S Suction location: The center of the
suction cover must be located between 2Ć1/2
and 3Ć1/2Ćinches up from the finished floor
surface.
