The Steamist TSG-15 is engineered for home steam rooms with dimensions up to 675 adjusted cubic feet (ACF).

The TSG-15 is constructed of corrosion-resistant stainless-steel for years of reliable, worry-free operation. The steam unit is equipped with industrial-grade heating elements, modular snap-in connection, durable electronic components, diagnostic LED displays, and a variety of other innovative features. 

Steamist Total Sense TSG Series generators are designed to provide the most pleasurable and consistent steam bathing experiences. The TSG-15 generator features advanced SteadySteam technology which maintains the user's temperature settings each bathing session. Steamist's advanced InstaMist technology heats the steam shower enclosure quickly.

The Steamist TSG-15 steam shower generator uses less than one gallon of water during a typical 20-minute steam session, making it both eco-friendly and economical. The TSG-15 is perfect for any steam shower kit.

The compact design of the TSG-15 allows the steam shower unit to be installed conveniently out of sight. Typical installation locations include vanities, closets, insulated attics and basements.

The Steamist TSG-15 15kW steam generator is available in 208V, single-phase (TSG 1521) three-phase configurations (TSG 1523), and 240V single-phase (TSG 1520) and three-phase (TSG 1522) configurations.

Steamist TSG residential steam room generators operate one or more of Steamist's Total Sense Spa Options for a luxurious home spa experience.

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

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

The TSG-15 steam bath generator requires 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 to help prevent harmful mineral buildup and calcification of the unit's heating elements and reservoir. The drain valve automatically drains the steam shower system after each use. For added convenience, the Auto Drain may be used with the available Steamist Generator Drain Pan.

The Steamist TSG-15 generator carries a limited lifetime warranty and is fully serviceable. Steamist steam generators are UL and CUL listed for your safety.
