Thermasol Unveils New Collection of Exceptional Saunas.

Thermasol® announces a new collection of indoor and outdoor saunas that are unparalleled in craftmanship and functionality. As a pioneer in luxury wellness technology for over 66-years, Thermasol’s new and innovative collection of Nordic-style saunas fuse the brilliance of Finnish technology with striking Northern European design. Enhancing an already impressive collection of steam, sauna, and plunge offerings, this new collection magnifies Thermasol’s longstanding commitment to wellness innovation and to offering their clients and customers the most sophisticated and immersive spa experience.

“Thermasol new collection derives from the company’s dedication to redefine the sauna for indoors and outdoors with exclusive wood finishes, Nordic designs and advanced heating systems with Wi-Fi enabled digital controls,” states Jennifer Thayer, Head of Region, North America & President of Harvia US Inc. “The collection also highlights Thermasol’s commitment to wellness with each new sauna providing a space for relaxation, recovery and rejuvenation.” 

The three new indoor saunas carefully combine natural woods with glass, enhancing the feeling of space and light for a complete wellness experience. The Aalto, named after the Finnish word for wave, brings Scandinavian luxury to life through fluid, sculptural design and a seamless blend of glass and wood. This indoor sauna is a true architectural statement—merging artistic elegance with advanced performance. The Astra, from the Latin for “stars,” invites you into a luminous indoor sauna experience where warmth meets serenity. Its glass-panel design and corner layout create a spacious, elegant feel while fitting seamlessly into modern interiors. The Lumaria, named from “Lumina” (light) and “Aria” (melody), blends light, warmth, and design in a refined indoor sauna experience. Available in two sizes—Medium (2–3 people) and Large (4-5 people)—Lumaria fits a variety of home wellness areas while maintaining a sleek, modern footprint. 

The five new outdoor saunas designed by Bojan Črešnar, the award-winning creator behind our sauna collection and a recipient of both the Red Dot and BIG SEE design awards. Each sauna reflects his signature blend of innovation, craftsmanship, and global perspective—and is thoughtfully designed as a private, light-filled retreat built for year-  round use.

The Fortis, meaning strength in Latin, is a sleek, is an enclosed outdoor sauna designed for 3–4 people. Its thermally modified brushed wood walls and aspen benches create a warm, inviting space, LED color light therapy adds ambiance, and multi-layer insulation and a protective roof ensure energy-efficient performance in any season. The Ombra, named after the Italian word for “shadow,” has signature reflective, tinted glass panels that create a soft, ambient glow—blending light and privacy to form a peaceful escape, day or night. Floor-to-ceiling windows invite nature in while preserving a sense of solitude, perfect for immersive relaxation under the sky. The Vue redefines outdoor wellness with a striking, panoramic glass front that connects you to nature while surrounding you in comfort. The full-glass façade is framed in black enamel and thermally treated wood, while the interior features brushed thermo-aspen benches and wood walls for a warm, inviting atmosphere. The Spectra is a compact, design-forward outdoor sauna that blends bold aesthetics with restorative wellness. Its sleek, single-glazed facade—available in natural or black wood—complements any garden setting. It’s a modern statement piece built for all-season use. The Vera is a compact, stylish outdoor sauna designed for patios, balconies, rooftops, garden corners, and other small outdoor living spaces.

The new collection comes on the heels of Thermasol’s brand refresh, which reflects their continued leadership in steam, sauna, and high-end bath and spa design. This evolution strengthens their presence across the wellness, and design industries, ensuring that they remain the premier choice for consumers, designers, and developers who seek the ultimate in relaxation, innovation, and craftsmanship. This transformation is also an exciting step forward for Thermasol, allowing their partners to better share their story and showcase their product offerings. While the look has been refined, the mission remains the same: to provide cutting-edge wellness solutions and unparalleled customer satisfaction.

“Thermasol has long been a leader in the plumbing industry, and our refreshed identity expands our presence into the worlds of design, commercial development, and hospitality,” states Jennifer Thayer Head of Region, North America & President of Harvia US Inc. “This powerful combination allows us to deliver not just exceptional products, but transformative wellness experiences that redefine relaxation and rejuvenation.”
