Thick Wall Design for Heat Retention

A snowy landscape at sunset features a log cabin and a barrel-shaped outdoor sauna. Bare trees stand in the background, and the sky glows with warm colors as the sun sets, casting long shadows on the snow.

Our barrel sauna kits use thicker staves than most barrel saunas on the market. The added mass improves heat retention, reduces temperature fluctuation, and minimizes exterior noise. Once heated, the sauna stays consistent, efficient, and comfortable throughout your session.

Thermally Modified Nordic Spruce Staves

The staves used in our kits are thermally modified using only heat and steam, permanently altering the wood at a cellular level. This process reduces moisture absorption, eliminates shrinkage, and increases resistance to rot. The result is a sauna that maintains its shape, seal, and performance year after year in changing outdoor conditions.

Precision Built Barrel Construction

A modern, black, barrel-shaped garden shed with a tall glass door, surrounded by lush green hedges and trees, sits at the end of a stone path in a landscaped backyard.

Each Thermory barrel sauna kit is engineered as a complete system. The staves are milled to exact tolerances so the barrel locks together under tension, creating a naturally strong and self-supporting structure. This construction allows the sauna to remain tight and stable without relying on excessive hardware or future adjustments.

Frequently Asked Questions

Our most common sauna questions from homeowners and customers.

If you're not ready to build a custom sauna but you still want to use one, there are many places where you can experience saunas in Vancouver, WA. If you don't want to deal with people, the Automated Wellness Center provides a private, no-contact sauna and other amenities. You can find saunas at many local hotels like Heathman Lodge or Red Lion Inn & Suites Vancouver. Or book sessions with small businesses like Connect Wellness and Uptown Sauna House for a unique experience. Wherever you go to try a sauna, make sure you read reviews and understand the rules and etiquette for that location.
We recommend staying in the sauna for 15 to 20 minutes per session. This gives you plenty of time to enjoy the benefits without overdoing it. If you're new to saunas, start with 5 to 10 minutes to ease into the heat.

For regular users, sessions can last up to 45 minutes, but it’s important to take breaks. A common practice, especially in Finland, is to step outside into the cold or take a cold plunge for a quick cool-down between sessions. This helps regulate your body temperature and enhances the sauna experience.

The number of calories burned in a sauna varies based on factors like your weight, metabolism, the sauna’s temperature, and how long you stay in it. On average:

  • In a 30-minute session, you can burn between 300 and 500 calories.
  • In a 1-hour session, the range is typically 300 to 600 calories.

When you're deciding what to wear in a sauna, here are a few things to keep in mind:

  • Loose-fitting clothing made of natural fibers like cotton or linen is ideal, as it allows your skin to breathe and helps regulate body temperature. Avoid synthetic materials or tight-fitting workout clothes, as these can trap heat and sweat.

  • A fresh pair of short-length compression shorts or performance material underwear can also work well for maintaining comfort.

  • In many cases especially in the Nordic countries, going into the sauna naked is common and even preferred, as it allows your body to sweat freely.

We recommend keeping the temperature in a traditional sauna between 155–195°F (70–90°C), with 180°F being a good balance between comfort and intensity.

For a more relaxing session, 160°F works well, while those who prefer a stronger heat might enjoy the 180°F range for a more invigorating experience.

We asked one of our IT guys if you should bring a phone into a sauna at about 180 degrees. He looked very concerned and shook his head. We would not recommend bringing a phone into a sauna as the heat would drive the internal temperature of the phone to unhealthy levels.

Also the humidity which is around 40%-60% in a traditional steam sauna could cause malfunctioning with the internal electronics. This not only applies for modern phones but also smart watches and other gadgets.
