What is the average warm-up time for a sauna?
It varies depending on the ambient temperature outdoors, the power of the heater, and the preferred sauna temp, but it typically takes about 40-50 minutes to get to 170F.
What is the difference between a wet and a dry sauna?
The difference between a wet and dry sauna is when there is an increase in humidity. To experience a burst of humidity and to transform your sauna from dry to wet, sprinkle water over your heated sauna stones. Sprinkling water over sauna stones is an age-old Finnish tradition and safe for all ThermaSol sauna heaters.
How do you “take” / use a sauna?
Taking a sauna is traditionally a rotation of dry, wet, dry, wet, etc., with cool-down breaks in between. A cool-down break can be as simple as sitting outside the sauna until you’re ready to enter again, or it can be something as crazy as jumping in an icy lake. However, sitting in the sauna for an extended period with no breaks is not recommended. The rule of thumb for sauna usage is whatever makes you comfortable. The moment it ceases to be comfortable, it ceases to be the proper way to take a sauna. If you are a new sauna user, starting with lower temperatures and smaller time frames is best and gradually increasing until you find your ideal comfort zone.
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.

How complex is assembly?
While the homeowner or contractor is responsible for assembling the sauna, all ThermaSol indoor and outdoor saunas ship with the walls, roofs, benches, backrests, and end sections pre-assembled and all holes pre-drilled, making this a seamless project for two. All that is required is a few hours and a typical household tool kit.
What are the average operating costs?
The unit operates on an efficient 240v heater and draws no more than 40 amps of power. Since the heater only draws power when it is in use, keep your sauna off when not in use to save energy. As a result, under regular use, it is similar to a clothes dryer or electric oven.
What sort of electrical service is required?
A licensed electrician must hard-wire the heater to an electrical source. Communicate to them: “It will require 220v power. The 4.5kw and 6.0kw heaters require a 30-amp breaker and 10/2 wire (for runs up to 90′ from the breaker box), and anything beyond in kW’s requires a 40-amp breaker and 8/2 wire. The light will require 110v, 15-amp service.”
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?
Over time, the lumber will weather naturally due to sun and rain, but this doesn’t harm the wood or impair the sauna’s performance. If you wish to retain the natural color of the wood, you can apply a stain with a UV inhibitor that resists weathering. Note: never treat the room’s interior and apply paint or varnish to the exterior. Depending on your area’s humidity and weather conditions, the wood will shrink or expand based on the amount of moisture absorption. After some time, you may need to tighten the bands or add additional filler staves.
What are the best practices for maintaining the interior of my sauna?


  • 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.


  • 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?
Ensure the barrel sauna is placed on a firm, flat surface; a slight taper for run-off is okay. You can set your sauna on a deck, concrete, paved stones, pressed gravel, etc. Cradle sauna supports are included and protect the sauna from moisture when placed directly on the ground. Saunas are freestanding and can be disassembled and moved.
What is the warranty?
  • Saunas: Limited Lifetime Warranty – Manufacturing Defects
  • Heater Components: 5-Year Warranty
  • Heating Elements: 1-Year 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.
