One thing people often overlook is insulation. If it’s done poorly, your sauna will take longer to heat and lose energy quickly.

How Outdoor Saunas Work
Outdoor saunas heat stones using a stove or heater. These stones then radiate heat into the air.

- Water creates steam
- Body begins sweating
Many first-time users notice the heat builds gradually. After about 10 minutes, sweating becomes much more intense.
