Cedar vs. Thermowood Saunas: What’s Best for Your Outdoor Space?

Cedar vs. Thermowood Saunas: What You Need to Know

When choosing a luxury outdoor sauna, one of the biggest decisions you'll face is the type of wood. Two of the most popular options today are cedar and thermowood. Both are heat-resistant, visually appealing, and commonly used in high-end saunas—but which one is better suited for your backyard sanctuary?

At Sauna Luxuries, we specialize in premium wellness products and feature top-tier brands like Leisurecraft cedar saunas. In this guide, we’ll break down the pros and cons of each wood so you can make the best decision for your space and lifestyle.

What is Thermowood?

Thermowood is softwood (often pine or spruce) that has been heat-treated to enhance its durability and resistance to moisture. The treatment process gives it a darkened, caramel-like appearance and increases dimensional stability.

• Pros: Budget-friendly, visually sleek, less likely to warp
• Cons: Less aromatic, can feel harder, may not age as gracefully as cedar

Thermowood is a good mid-range choice for modern sauna aesthetics—but it lacks some of the natural benefits cedar provides.

Why Cedar Is the Gold Standard for Saunas

Used in traditional sauna-building for centuries, red cedar—especially Canadian red cedar—offers a unique combination of performance and luxury.

• Natural aroma: The wood releases a calming scent that enhances the sauna experience.
• Anti-fungal and rot-resistant: Cedar is naturally suited to handle moisture and heat.
• Stays cool to the touch: It insulates well and won’t overheat, even during long sessions.
• Long-term durability: Cedar weathers beautifully and resists warping or cracking over decades.

This makes cedar saunas the top pick for wellness lovers who want a timeless, low-maintenance outdoor solution.

Build & Maintenance: Which Lasts Longer?

While both woods are designed for durability, cedar saunas have the edge in longevity with less upkeep. Thermowood may require occasional re-oiling to maintain its appearance, especially when exposed to direct sun or snow.

Cedar’s natural oils act as a built-in preservative, making it a better long-term investment for outdoor environments—especially in humid or rainy climates.

Which Feels Better?

Thermowood has a smooth, modern feel, but lacks the warmth and softness of cedar. If you’re using your sauna frequently, you’ll appreciate how cedar remains gentle on skin—even in high heat.

Plus, the aroma of cedar adds a spa-like quality that thermowood simply can’t replicate.

Design & Aesthetic Differences

Thermowood has a dark, uniform tone that works well with minimalist or contemporary architecture. Cedar, on the other hand, features rich red and golden hues with a more rustic, natural appeal—ideal for blending into wooded or nature-inspired outdoor settings.

Popular Leisurecraft cedar sauna models like the Luna or Harmony Barrel Sauna combine traditional wood grain with sleek silhouettes, offering the best of both worlds.

Which Sauna Is Right for You?

If you’re after modern aesthetics and a lower price point, thermowood may work well. But for a high-end, sensory-rich sauna that lasts for decades, cedar remains unmatched.

At Sauna Luxuries, we recommend exploring our hand-picked collection of Leisurecraft cedar saunas to find your ideal fit—whether you're creating a cozy backyard retreat or a full spa installation.

Final Verdict: Cedar Reigns Supreme

While thermowood offers a sleek, functional alternative, cedar is the clear choice for anyone serious about wellness, design, and long-term value. Its superior aroma, natural durability, and timeless beauty make it the top material for luxury outdoor saunas.
