When people ask about the best wood for a sauna, one name always comes up: red cedar.
More specifically, Western Red Cedar.
But is red cedar for sauna construction really worth it? Or is it just hype? Let’s dive deep into its qualities—history, beauty, comfort, and even its environmental impact. By the end, you’ll know whether this wood is the right match for your sauna project.
Why Choose Red Cedar for Sauna Building?
Red cedar has been valued for centuries, especially among Indigenous peoples of North America. They knew what modern wellness enthusiasts are rediscovering: cedar is strong, aromatic, and long-lasting.
That’s exactly why today’s sauna room manufacturers still use it in so many builds.
Here’s what makes red cedar stand out in sauna construction:
Durability – It naturally resists decay and rot.
Comfort – Surfaces don’t get scorching hot.
Aroma – The wood releases a soothing scent.
Beauty – Rich color and grain patterns make every sauna inviting.
Red cedar isn’t just a practical choice. It creates an atmosphere.
Thermal Performance: How Red Cedar Handles Heat
Think of red cedar as a buffer between you and the harshness of sauna heat.
This wood has low thermal conductivity, which means it doesn’t store heat the same way dense materials like concrete or steel do. In practice, this means:
The benches stay comfortable to sit on.
The walls don’t radiate burning heat.
The sauna retains warmth without wasting energy.
This is why many wellness centers and even traditional sauna room distributors prefer cedar. It’s not just about the heat itself—it’s about making the heat enjoyable.
Aesthetic Appeal: The Look of Red Cedar
Looks matter, even in a place where you’ll be sweating.
Red cedar has natural reddish tones that shift toward silver-gray with age. Some owners love the deep warm color when the sauna is new. Others adore the weathered, rustic look that develops over time.
The grain patterns add a sense of natural luxury. It feels more like a retreat than just a room with heat. That’s why designers and traditional sauna room dealers often recommend cedar—it’s practical and stylish.
Stability and Longevity
Heat. Steam. Cool-down. Repeat. Saunas go through extreme cycles, and not every wood can handle it.
Red cedar can.
It resists warping, cracking, and shrinking. Its cellular structure and natural oils protect it. With basic care, a red cedar sauna can last 40 to 50 years.
That’s not just long-lasting. That’s a generational investment.
History of Red Cedar in Wellness
For thousands of years, Western Red Cedar has held cultural importance. Indigenous communities used it for clothing, canoes, and even medicine.
When modern wellness culture adopted the sauna, cedar was an easy choice. It brought strength, beauty, and a natural sense of peace to the sauna environment.
Even today, sitting in a red cedar sauna connects you with a tradition that stretches back centuries.
Health Benefits of Red Cedar in Saunas
Let’s get real—many people pick red cedar for more than looks and strength. They pick it because of how it makes them feel.
The essential oils in cedar release a gentle fragrance when heated. Many say it:
Relieves stress
Clears the mind
Helps them breathe easier
Some even describe it as nature’s aromatherapy session.
It’s not just about scent. The oils also deter pests and mildew, which means fewer chemicals are needed for protection. This makes cedar not only healthy for you but also better for the environment.
⚠️ But a note of caution: always choose high-quality cedar. Low-grade wood can sometimes release unwanted chemicals when exposed to heat.
Maintenance: Keeping Your Red Cedar Sauna in Shape
The good news? Red cedar doesn’t need much babying.
To keep your sauna fresh and strong:
Wipe benches after use.
Use towels to protect surfaces.
Sand lightly if the surface looks worn.
Skip harsh sealants—chemicals and heat don’t mix well.
Some sauna fans prefer to let cedar age naturally. The faded look tells a story of years of relaxation.
If you’re building your own project, consider custom traditional sauna room options. They let you design around cedar’s strengths while adding your own touch.
Environmental Impact: Is Red Cedar Eco-Friendly?
This is a big one for modern buyers.
Most red cedar comes from the Pacific Northwest, where sustainable forestry is practiced. Many companies replant trees or harvest selectively to protect forests.
Because cedar naturally resists rot, it doesn’t require chemical treatments like other woods. That’s fewer toxins for the planet.
When sourced responsibly, red cedar for sauna construction is a win for both wellness and sustainability.
