If you are installing the unit or thinking of adding one on your next project,
you will need to make sure the unit is sized properly.
Calculate the shower area
(Length x Width x Height = Cubic Feet)
and confirm the ceiling height does not exceed 8 feet.
The set of numbers in the generator model number
represents the maximum capacity.
Example: Generator model SSA-240
will be sufficient up to 240 cubic feet
(with a ceiling not exceeding 8 feet in height).
Up-size 1 Unit size for every foot over 8 foot to
a maximum of 10 foot.
Model number can be found on the box or generator.
ThermaSol’s generators can be placed up to 50 feet from the
shower; in an attic, closet or below a sink are ideal locations.
Make sure the walls, ceiling and floor materials are suitable for
use with steam. If using acrylic walls, they must be steam rated
from their manufacturer. ThermaSol only recommends SSA-ACR
generator for acrylic modules.
