The 400 Cubic Feet 4-Room Steam Generator from the ThermaSol Day Spa Series is engineered for facilities operating four steam rooms up to 400 Cubic Feet each.
With 16.0 kW of output and dual independent breaker configuration, this system supports larger steam environments requiring stable high-volume production across four simultaneous rooms.
High-volume steam production for four large suites in demanding commercial spa environments.
The dual independent breaker setup distributes electrical load safely across circuits, supporting continuous four-room operation without instability — designed for demanding hotel spa floors, large leisure facilities, premium health clubs, and destination wellness centres.
Real-time energy regulation via SmartSteam™ ensures consistent steam density without sudden temperature changes — maintaining balanced steam saturation across all four rooms even during peak operational hours.
Industrial-grade stainless steel construction combined with split-tank design separates heating from water feed functions, improving efficiency and protecting internal components in high-demand four-room installations.
Sediment management via the integrated PowerFlush™ system helps maintain heating efficiency and extend lifespan across all four large suites — particularly important in high-output configurations under sustained commercial use.
Protected by ThermaSol's 5-Year No-Questions-Asked Commercial Warranty, the Day Spa 400 4-Room is built for reliable professional operation in busy hotel spas, health clubs, and large wellness facilities.
Designed, engineered, and built in the U.S.A.
Watch how the ThermaSol Day Spa Series delivers high-output steam across four large suites with dual independent electrical control and consistent simultaneous performance.
