A half-century of designing, engineering and constructing luxury steam shower systems has turned ThermaSol into an industry leader. The result of this experience is the Pro-850, among the world’s most popular generators. The ThermaSol Pro-850 24kw steam shower generator is designed for large home steam bath enclosures from 900 to 1200 adjusted cubic feet (ACF).

Made of durable stainless-steel components, the Pro-850 generator provides years of reliable and maintenance-free operation. The unit features durable electronic components, industrial-grade heating elements, a water-level safety system, a thermostatically controlled retractable steam head, and a variety of other features. The generator includes an advanced Auto PowerFlush inner-tank cleaning system to clean the generator tank and ensure the longevity of the unit.

When designing this generator, ThermaSol focused on ensuring the most consistent bathing experience for homeowners. The Pro-850 steam generator features fully-integrated CAN-bus digital technology for intelligent two-way communication between the generator and the control. The unit is equipped with patented FastStart technology so that you may start steaming quickly. The Pro-850 includes the SmartSteam feature which heats the steam room safely and efficiently.

Controls can be paired with the Solitude Wireless mobile app to control features such as bathing duration and temperature of the steam shower. Each control package option is available in a variety of stylish finishes to suit your preferences.

The compact size of the unit allows it to be installed conveniently out of sight up to 50 feet away from the steam shower enclosure.
