Why Rogue Sauna Builds With Lunawood

Why Rogue Sauna Chooses Lunawood for Unmatched Outdoor Sauna Craftsmanship

Born in Southern Oregon and inspired by centuries of Finnish sauna tradition, Rogue Sauna creates handcrafted sanctuaries designed for connection, restoration, and enduring beauty. At the heart of every Rogue build is a commitment to sustainability, wellness, and world-class materials—and that’s why we use Lunawood ThermoWood® in all of our premier home outdoor saunas.

Sourced responsibly from Finland, Lunawood’s thermally modified spruce is 100% chemical-free and engineered for lasting performance in any climate. Its natural resistance to decay, exceptional stability, and beautiful aging process make it ideal for both the interior and exterior of our saunas. Whether it’s the warm caramel tone or the smooth tactile feel of the wood, Lunawood elevates both the look and experience of every Rogue sauna.

Combined with a rugged steel frame and timeless design, Rogue Sauna delivers a modern wellness retreat built to last—where tradition, craftsmanship, and nature come together in perfect harmony.

A LUXURY SAUNA STARTS WITH THE BEST MATERIALS ON THE MARKET

Rogue Sauna selects Lunawood ThermoWood® as the cornerstone of its sauna design because it represents the perfect balance of natural beauty, resilience, and sustainability. Crafted from certified Scandinavian timber grown in the Nordic forests for nearly 80 years, Lunawood is thermally modified using only heat and steam—no chemicals—preserving its organic integrity while enhancing its durability.

This process results in wood that’s exceptionally stable, resistant to decay, and ideal for both interior and exterior use, even in the harshest conditions. Lunawood’s rich texture and warm tone bring a refined, Nordic aesthetic to every Rogue sauna, while its maintenance-free nature makes it an environmentally responsible choice throughout its long life cycle.

From its natural origins to its architectural elegance, this is why Rogue Sauna trusts Lunawood—to deliver saunas that are not only built to last, but crafted to inspire.

What is Thermowood?

ThermoWood® is a patented wood material processed entirely without chemicals, using controlled temperatures ranging from 180°C to 230°C. This thermal modification significantly enhances the wood's chemical and physical properties, boosting its durability and stability. As a result, ThermoWood® exhibits superior resistance to decay, reduced moisture content, and minimized tendencies for warping, swelling, and shrinking compared to untreated wood
