The Steamist TSG-20 is designed for steam rooms with dimensions up to 900 adjusted cubic feet (ACF).

The TSG-20 includes a stainless-steel tank, professional-grade heating elements, durable electronic components, color diagnostic LED displays, and a variety of other innovative components.

The high-efficiency, low-maintenance Steamist TSG-20 steam shower generator is built to support the most demanding steam room environments. Steamist Total Sense Series generators are engineered to provide years of exceptional performance and reliable operation.

The TSG-20 steamer features advanced SteadySteam technology which maintains the user's temperature preferences and prevents any unexpected temperature spikes. The included InstaMist feature heats the steam shower enclosure quickly and efficiently.

The Steamist TSG-20 steam bath generator uses less than one gallon of water during a typical twenty-minute steam bathing session, making it both eco-conscious and economical.

The compact TSG-20 steam unit can be installed conveniently out of sight. Typical installation locations include closets, cabinets, insulated basements and attics. 

The Steamist TSG-20 20kW steam generator is available in 208V, single-phase (TSG-20-208), three-phase configurations (TSG-20-208/3), and 240V single-phase (TSG-20) configurations.

Steamist Total Sense Series generators operate one or more of Steamist's Total Sense Spa Options for an elevated home spa experience. 

Steamist TSG generators are delivered factory assembled, carefully wired, and tested to ensure quality.

Steamist TSG steam generators have the flexibility to be linked in tandem to accommodate larger steam rooms.

The Steamist TSG-20 steam shower unit requires the use of a Steamist digital control or control package for operation. Select the available control with features that best suit your preferences.

We recommend the Steamist Auto Drain valve which automatically drains the system after each use. The Auto Drain valve helps prevent harmful mineral buildup and calcification of the unit's heating elements and reservoir. For added convenience, the Auto Drain may be used with the available Steamist Generator Drain Pan.

The Steamist TSG-20 steam room generator carries a limited lifetime warranty and is fully serviceable. Steamist generators are UL and CUL listed for your safety.
