The 400 Cubic Feet 2-Room Steam Generator from the ThermaSol Day Spa Series is designed for commercial facilities operating two large-capacity steam rooms up to 400 cubic feet each.
With 16.0 kW of output, this system is engineered for higher steam demand, faster recovery times, and stable performance in busy spa environments where session turnover is frequent.
Particularly suited for hotel spa suites, destination wellness centres, high-traffic leisure facilities, and premium health clubs.
High-output performance for large commercial steam rooms with frequent session turnover.
As room size increases, temperature stability becomes more critical. SmartSteam™ continuously regulates energy delivery to maintain consistent heat levels without fluctuation — even under simultaneous room operation, output remains balanced and controlled.
The 400 Cubic Feet model utilises dual independent breakers to safely manage the higher energy demand required for larger rooms.
The split-tank design separates heating from water feed functions, reducing scale exposure to heating elements and improving system longevity. For larger steam rooms, this ensures consistent steam density without overworking the generator.
Integrated PowerFlush™ cleaning technology helps prevent mineral buildup inside the tank. In commercial environments with continuous use, this reduces maintenance interruptions and protects long-term performance.
Backed by ThermaSol's 5-year commercial warranty, the Day Spa 400 is built for peace of mind in demanding professional installations.
Designed, engineered, and built in the U.S.A. for dependable long-term performance across hotel spas, leisure facilities, and premium wellness centres.
Watch how the ThermaSol Day Spa Series delivers high-output steam performance across two large-capacity rooms with stable, independent control.
