Premium Spruce & Thermally Treated Aspen Timber

The Kuusi blends the best of both worlds: a light-toned spruce exterior and a thermally treated Aspen interior for true spa-level comfort. Spruce offers a strong yet lightweight structure with low thermal conductivity, helping retain heat efficiently while maintaining a clean, modern Scandinavian look. Its pale finish also gives you the flexibility to stain or customise the exterior to suit your home.

Inside, thermally treated Aspen shines. Designed to withstand repeated heating cycles, it resists warping, shrinking and cracking. It stays comfortable against the skin, doesn’t overheat like dense hardwoods, and features a soft, neutral scent perfect for those who prefer a calm, balanced sauna environment.

Light Spruce Exterior

Finished in a beautiful, light-toned spruce timber, the Kuusi’s exterior delivers that clean Scandinavian sauna aesthetic straight out of the box, but it doesn’t stop there. The natural grain and pale colour make it ideal for staining or finishing to suit your home’s interior style. Whether your space leans coastal, contemporary, minimalist or warm and earthy, you can tailor the look to blend seamlessly. It’s wellness that doesn’t just feel good; it fits beautifully into your home.

Active Ventilation For Cleaner, Full-Body Heat

Unlike many other traditional saunas that rely on vented floors, often leaving your feet and legs noticeably cooler, the Kuusi uses an Active Ventilation System that draws and circulates air more effectively. This allows for fully sealed flooring that retains heat evenly from head to toe, staying true to authentic Finnish sauna principles. Fresh air is drawn in through intake vents beneath the heater, while an induction fan discreetly located under the bench helps extract excess CO2, keeping the atmosphere clean and oxygen-rich. At the top of the sauna, a strategically placed exhaust vent stimulates natural air movement, encouraging the even circulation of hot air throughout the space. The result is up to 6 to 8 full air changes per hour, delivering a fresher, more balanced environment that enhances your comfort and the overall effectiveness of every session.

ThermaShield Wall System For Superior Heat Performance

Designed to create a true Finnish sauna environment, the kuusi features a robust 15 mm ThermaShield insulation core paired with 10 mm internal timber panels. This layered wall system locks in heat more efficiently, allowing the sauna to warm faster and maintain stable temperatures throughout your session. For busy households, this means less waiting, reduced energy use, and a more consistent, comforting heat that penetrates deep into muscles and joints. It’s the perfect balance of tradition and modern thermal engineering.

Double-Tier Seating For Flexible Sessions

Every sauna session is different and the Kuusi gives you the flexibility to tailor your experience. The double-tier bench design allows you to choose between the hotter upper bench or the slightly cooler lower level, depending on your preference or tolerance that day.

Whether you’re easing into a gentle wind-down after work or pushing for a more intense heat session post-training, you’re in control. It’s ideal for families or shared sessions too, allowing everyone to find their comfort zone while enjoying the same restorative benefits of traditional sauna therapy.

Complete Accessory Kit Included

Everything you need for the ultimate sauna session comes included with the Kuusi. From day one, you'll be fully equipped with a curated set of quality accessories designed to complement both form and function. Each kit includes a sand timer, precision hygrometer, matching bucket and ladle, and more – all crafted to enhance your ritual and elevate your home spa experience. It’s the finishing touch that makes every session feel effortless and complete.
