The optimal sauna temperature range is 70°C to 93°C. At these intense dry heat levels, your body experiences therapeutic stimulation through sweating, increased heart rate and deep heat penetration. That said, it’s important that you find what's most comfortable for you - some prefer it even hotter while others enjoy a more moderate traditional Finnish sauna session around the 70-80°C range. No matter your preference, our sauna heaters and their intuitive controls allow you to precisely dial in the perfect temperature for your needs.
