The compact steam shower unit can be conveniently installed in vanities, cabinets, and other out of sight locations.

Amerec AK series generators have the flexibility to be linked in tandem to accommodate steam rooms larger than 550 adjusted cubic feet. Connection cables are sold separately, and each generator requires a ComfortFlo steam head.
