How this quiz works
This tool turns the full spectrum versus far infrared decision into a simple score. Each answer adds points toward either full spectrum, which uses near, mid, and far infrared, or far infrared, which uses the far band alone. Buyers who want the widest wavelength coverage, use a sauna often, and have room in the budget tend to score toward full spectrum. Buyers who mainly want relaxation and a deep sweat at the best price tend to score toward far infrared. The result is a recommendation, not medical advice, and you can always reach our team to talk it through. The interactive result is free. Joining our email list is optional.

Both deliver the core sauna benefits that the Cleveland Clinic ties to regular infrared use, including relaxation and temporary muscle relief. Full spectrum adds near infrared, the band most associated with skin and surface tissue, which is why goal-focused buyers pay the premium.

Frequently asked questions
Is full spectrum better than far infrared?
Not strictly better, but broader. Full spectrum covers near, mid, and far infrared while far infrared covers one band well. Most measured sauna benefits come from far infrared; full spectrum adds wavelengths some buyers want, especially for skin, at a higher price.
How much more does full spectrum cost?
Usually $500 to $2,000 more than a comparable far infrared sauna, depending on size and the extras bundled in. Confirm the cabin includes genuine near and mid infrared before paying the premium.
How do I know which I need?
If you want every infrared band and use a sauna often, full spectrum fits. If you want relaxation and a strong sweat at the lowest sensible price, far infrared is the smarter spend. This quiz weighs those factors for you.
