Check PriceFrequently Asked Questions
Are infrared saunas cheaper to run than traditional saunas?
Yes — infrared panels heat the body directly rather than the whole cabin's air, which generally means lower electricity use and shorter warm-up times.
Do infrared saunas need a special electrical circuit?
Compact single-person cabins often run on a standard outlet, while larger multi-person cabins may require a dedicated circuit — check the manufacturer's spec sheet.
What does full-spectrum infrared mean?
It means the cabin combines near, mid, and far-infrared emitters in one unit rather than relying on a single wavelength.
