As saunas continue to grow in popularity across North America, we’re seeing a clear pattern in what people are searching for, and what they really want to understand before they buy or build.
From health benefits to materials to installation, these questions come up again and again. Here’s how we answer them, based on what we’ve learned working with thermally modified wood and premium sauna builds for years.
“Are Saunas Good for You?”
This is one of the most common and important questions.
The short answer: yes, when used properly, saunas can offer real health benefits.
People who use saunas regularly report lower stress, less pain, better sleep, and higher overall well-being—even with as little as 1–4 sessions per month. This comes from a study of nearly 1,000 adults in Sweden, showing that even moderate sauna use is linked to noticeable improvements in day-to-day health, not just long-term outcomes.
We always encourage people to think of sauna use the way Scandinavians do: not as a luxury, but as a regular wellness routine.
“Traditional Sauna vs. Infrared”
This is where we tend to spend a lot of time educating. (Check out our full guide here!)
Traditional Finnish saunas, like Thermory’s, heat the air (typically 160–200°F), creating a full-body experience that encourages deep sweating and full thermal cycling.
Infrared saunas operate at lower temperatures and heat the body more directly.
Both have their place, but many of the long-term studies, including the Finnish research, are based specifically on traditional sauna use. That’s why we focus on building materials for traditional saunas. The experience is immersive, time-tested, and rooted in centuries of use.
“How Long Should You Stay in a Sauna?”
Most experts recommend 15–20 minutes per session, depending on heat level and personal tolerance.
We typically suggest:
- Start shorter (5-10 minutes)
- Cool down between rounds
- Hydrate consistently
Consistency matters more than duration. The health benefits seen in studies come from repeated, long-term use, not one long session.
“What Are the Real Health Benefits of Sauna Use?”
Beyond cardiovascular benefits, research has linked regular sauna use to:
- Reduced risk of stroke (up to 61%) in frequent users
- Improved circulation and vascular function
- Muscle recovery and reduced soreness
- Stress reduction and improved sleep
There’s also growing evidence around mental health benefits, particularly tied to relaxation and routine. We’ve seen firsthand how incorporating sauna into a weekly rhythm can change how people feel, physically and mentally.
“What’s the Best Wood for a Sauna?”
This is where our expertise really comes in. Explore our guide to the best wood species for saunas.
Not all wood performs the same in high-heat, high-moisture environments. Traditional options like cedar and spruce are common, but thermal modification takes performance to another level.
Through thermal modification, we heat wood to over 400°F in a controlled environment, permanently changing its cellular structure. The result:
- Improved dimensional stability (up to 50% more stable)
- Significantly increased resistance to rot and decay
- Lower moisture absorption
- A smoother, splinter-resistant surface
At Thermory, we’ve built our reputation around this process. It allows us to offer real wood that performs predictably in one of the most demanding environments: a sauna.
“What Does a Home Sauna Cost?”
This varies widely, but here’s a realistic range for Sauna Kits by Thermory:
- Barrel Saunas: $8,000+
- Sauna Squares: $12,000+
- Mod Series: $15,000+
- The Luik: $25,000+
What moves price the most?
- Size (2-person vs 6–8 person)
- Heater choice (electric vs wood-burning)
- Glass front/window upgrades
- Porch additions
- Insulation + interior finish level
- Freight + install complexity
Where we see the biggest difference is in materials and longevity. Investing in better materials from the start results in a longer-lasting, better-performing sauna.
We also offer an extensive line of sauna materials for custom saunas.
“What Makes a Great Outdoor Sauna?”
Outdoor saunas face constant exposure—moisture, UV, temperature swings. That’s why material choice matters so much.
Thermally modified wood is particularly well-suited here because it:
- Holds its shape in changing climates
- Resists rot without chemical treatments
- Maintains a consistent appearance over time
We’ve seen projects across North America, from humid Southeast climates to freeze-thaw cycles in the Northeast, where performance consistency is critical.
“How Do You Build a Sauna at Home?”
There are two main paths:
Either way, the key components remain the same:
- Proper insulation and vapor barriers
- Ventilation for airflow and comfort
- A sturdy and level surface
- A reliable heater
- And most importantly, materials that can handle the environment
This is where we work closely with partners and builders, to ensure the materials going into a sauna are built to last, not just look good on day one.
Final Thoughts
What we’ve found is that most sauna questions fall into two categories:
“Is this good for me?” and “What should I build it with?”
Both matter.
The health benefits are real and well-documented, but the experience itself is shaped by the quality of the environment you create. Materials, craftsmanship, and design all play a role.
At Thermory, we’ve spent years focused on one piece of that puzzle: making sure the wood performs as beautifully as it looks – session after session, year after year.
