The 650 Cubic Feet 3-Room Steam Generator from the ThermaSol Day Spa Series is designed to power three large steam rooms up to 650 Cubic Feet each.
With a 20.0 kW heating capacity, this configuration is engineered for large-scale commercial wellness facilities where sustained steam volume and stable atmospheric conditions are critical throughout extended operating hours.
Maximum-output steam for three expansive suites in premium resort and destination spa facilities.
Well suited for resort spa complexes, luxury hotel wellness centres, high-capacity destination spas, and architect-designed steam facilities — the 20.0 kW output supports rapid heat-up times and dependable steam saturation across three large cubic footage rooms.
The 20.0 kW configuration operates on dual independent breakers to safely manage higher energy demand, enhancing electrical stability and supporting continuous multi-room operation without strain.
The stainless steel housing and split-tank system reduce wear on heating elements while improving operational efficiency — designed to withstand sustained use across three large commercial steam rooms day after day.
Regular use of the PowerFlush™ system helps maintain optimal heating performance by breaking down sediment buildup inside the tank — especially important in higher-output configurations servicing three large rooms.
Backed by ThermaSol's 5-Year Commercial Warranty, the Day Spa 650 3-Room delivers long-term operational confidence for resort spas, luxury hotel developments, and large-scale destination wellness centres.
Designed, engineered, and built in the U.S.A.
