Do You Need to Waterproof a Sauna?

You generally do not have to waterproof an outdoor sauna, as most saunas are constructed in such a way that they can handle high humidity and extreme temperature fluctuations. The type of wood used on the sauna, including cedar or hemlock, has a natural resistance to moisture and will not rot; thus, it also stands strong over time. On the other hand, it does need proper ventilation and maintenance to last and work properly.

How to Maintain Sauna Protection:

• Seal the Outside: While the interior does not require sealing, a waterproof coating on the exterior of the sauna safeguards against rain, snow, and UV.
• Check for Leaks: Periodically check the roof and joints for any areas where water may enter the sauna.
• Proper Drainage: Ensure that the base directs water away from the sauna.

Avoid the temptation to seal or waterproof the wood inside, as this will simply trap moisture and prevent the sauna from breathing naturally.
