Thermasol, a Round Rock, Texas-based manufacturer of steam showers, has introduced a new collection of indoor and outdoor saunas featuring hip design and European craftsmanship. The company says the collection of Nordic-style saunas fuse the brilliance of Finnish technology.
“Thermasol’s 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,” says Jennifer Thayer, head of region, North America and president of Harvia U.S., which acquired Thermasol in 2024. “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 users into a luminous indoor sauna experience where warmth meets serenity. Its glass-panel design and corner layout create a spacious feel while fitting seamlessly into modern interiors.

The Lumaria, derived from Lumina (light) and Aria (melody), blends light, warmth and design in a refined indoor sauna experience. Available in two sizes—Medium (two to three people) and Large (four to five people)—Lumaria fits a variety of home wellness areas while maintaining a sleek, modern footprint.
The five new outdoor saunas were designed by Bojan Črešnar, the creator behind the company’s sauna collection and a recipient of both 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, enclosed outdoor sauna designed for three to four 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 ensures energy-efficient performance in any season.

The Ombra, named after the Italian word for “shadow,” has reflective, tinted glass panels that create a soft, ambient glow—blending light and privacy to form a peaceful escape. Floor-to-ceiling windows invite nature in while preserving a sense of solitude, perfect for immersive relaxation under the sky, the company says.

The Vue redefines outdoor wellness with a dramatic, panoramic glass front that connects users to nature while surrounding them 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.
