The 650 Cubic Feet 2-Room Steam Generator represents the highest output configuration within the ThermaSol Day Spa commercial range.
Delivering 20.0 kW of heating power, this system is engineered for large-scale spa rooms up to 650 cubic feet each — ideal for luxury wellness facilities and high-end hospitality projects.
Best suited for resort spas, large destination wellness centres, premium hotel developments, and architect-designed commercial steam suites.
Maximum-capacity steam for resort spas, luxury hotels, and architect-designed wellness suites.
Larger steam rooms require sustained output without performance drop. The 20.0 kW rating ensures rapid heat-up times and stable atmospheric conditions even during extended operating hours — giving guests a consistent experience throughout.
The 650 Cubic Feet model operates on dual independent breakers to manage increased electrical demand safely.
The industrial-grade stainless steel housing and split-tank engineering are designed to withstand continuous commercial operation while minimising scale exposure and internal wear — keeping the system performing at its best over years of heavy use.
With higher output comes greater mineral exposure. The integrated PowerFlush™ system ensures sediment is actively managed at scale, helping preserve heating efficiency and protecting the long-term investment in your commercial steam installation.
Backed by ThermaSol's 5-year no-questions-asked commercial warranty, the Day Spa 650 delivers long-term operational confidence for the most demanding luxury installations.
Designed, engineered, and built in the U.S.A. for resort spas, premium hotel developments, and architect-specified commercial steam environments.
Watch how the ThermaSol Day Spa Series delivers maximum-capacity steam performance across two large luxury rooms with stable, independent control.
