what should a single sauna's temp be set at
- The sauna has very low humidity which means it can be much hotter than a steam bath. Saunas are usually between 176Â°F (80Â°C) and 212Â°F (100Â°C) with low humidity +/-10%, while a steam bath is usually around 104Â°F (40Â°C) to 116Â°F (46Â°C) with a relative humidity of around 100%.
