Longevity by Design™
Heat, then cold. Designed as one ritual.
Symmetry saunas are made to order in Nordic aspen, thermo-alder or Western Red Cedar, with Harvia, Tulikivi or HUUM stone heaters or ultra-low EMF infrared. Its baths are hand-built in Estonia, finished in stone or wood, and run from 41 to 104°F, so one piece can be a cold plunge or a warm soak. The equipment sits in a separate cabinet on most models, keeping the bath quiet and clean-lined.

Before you buy
Common questions.
How is pricing set?
Each Symmetry piece is made to your size, heat and finish, so we send a written quote with Symmetry's lead time before you commit.
Infrared, hybrid or traditional heat?
Infrared runs cooler, from about 130–165°F. Traditional Finnish heat reaches 194°F+ with steam, and hybrid lets you use either. Chat with us and we'll help you decide.
Do I need an electrician or plumber?
Plan on a licensed electrician for any stone heater or chiller, and a plumber or builder for drain and fill connections on plunges where needed.
Should I check with my physician first?
Yes, especially if you have a heart condition or high or low blood pressure, are pregnant, or are recovering from an injury or surgery. Heat and cold exposure place real demands on the body.
