Since 1983. Saunas since 1997.
We began as a consulting company in California, moved to Boulder, Colorado in 1999, and have been designing far infrared saunas longer than any other US company. Here’s how we got here.
Founded 1983 · Infrared saunas since 1997 · Boulder, Colorado

A Different Kind of Sauna Company
We’ve been designing far infrared saunas since 1997, when we introduced our first Thermal Life® models. Our team includes an electrical engineer, a chiropractor, a holistic health practitioner, a nutritionist, a biochemist, a biologist and a psychotherapist.
Thousands of health practitioners recommend our saunas, and they appear in more than 40 published books on detoxification, longevity and environmental health. We pioneered low-EMF heater design, with US patents 9,770,386 and 10,765,597 (Google Patents, new tab).
Decades of work with environmental medicine practitioners, and with some of the most chemically sensitive people anywhere, have shaped every sauna we make. Today our saunas are used in environmental health centers that care for people with serious health challenges.
Family owned. Sauna specialists since 1997. Carbon negative since 2010.
