What is the difference between a wet and a dry sauna?
How do you “take” / use a sauna?
How is a traditional sauna experience different than an infrared experience?
A traditional sauna uses water to generate steam, so technically, the infrared experience is not a sauna at all. Infrared does not warm the room but penetrates the body only where the infrared rays are in direct view of the body, “direct heat.” The proper definition for the infrared experience is to refer to it as an “infrared therapy room,” a low-temperature space that helps relieve sore joints and muscles. A traditional sauna is a total body experience, providing not only joint and muscle relief but other health benefits, such as respiratory relief, endorphin & stress relief, skin rejuvenation, detoxification, caloric burn & weight loss, and better sleep.

Can an outdoor barrel sauna go indoors?
Yes, while our barrel saunas are designed with the outdoors in mind, they will work equally as well indoors as it does outdoors.
Can an indoor sauna go outdoors?
We do not advise it, but it is possible. A shelter is needed since indoor saunas have a flat top and are not designed to shed water. It is also recommended to increase the heater size due to the higher amount of glass used in indoor saunas and climate variables.
Increase the heater by one size if:
- The indoor sauna is enclosed and non-climate-controlled, like a garage.
Increase the heater by two sizes if:
- The indoor sauna will be in a non-climate-controlled area, like a garage, with freezing temperatures and/or an elevation of over 5k feet.
- The indoor sauna is placed outside under a covering (canopy) but still exposed to weathered elements.
How do I maintain the exterior of my outdoor barrel sauna?
What are the best practices for maintaining the interior of my sauna?
Regularly
- Saunas should be kept clean and odor free.
- When not in use, leaving the door & vents open allows the sauna to “breathe.”
- Bathers should always sit on a towel; otherwise, perspiration may penetrate the softwood.
Every Few Weeks
- Wipe the benches with a damp cloth and use warm water when necessary.
- Vacuum the interior.
- Clean glass always enhances the sauna’s appeal.
Annually
- Remove the stones from the heater cavity, and check for any cracks. Replace stones as needed.
- Use a hand vacuum on the heater cavity to remove dust, debris, or small chipped stones.
- Rinse the sauna stones and thoroughly dry them before returning them to the heater cavity.
- Use fine-grit sandpaper on any tough bench stains.
How do I decide where to place my outdoor barrel sauna?
What is the warranty?

What health benefits can I expect to experience and gain from regular sauna use?
The health benefits attributed to sauna usage are directly linked to the level of heat that the rooms can obtain. These benefits include pain relief, muscle relaxation, respiratory relief, endorphin & stress relief, skin rejuvenation, detoxification, calorific burn & weight loss, and better sleep.
