"It's become a daily ritual… I ordered from real Finns at Saunamo — one of the best saunas I've ever seen… It's an investment in health, longevity and quality of life."
Materials chosen for clean Nordic design and efficient heat
In the Usko line, radiata thermo pine, thermo aspen benches and a waterproof insulated roof create an outdoor sauna that feels simple, efficient and ready for regular use.
🇪🇺
Designed and made in the EU
Tempered glass front
The 8 mm tempered glass gives Usko its open front view while keeping the cabin clean, strong and easy to place.
Waterproof insulated roof
The insulated roof helps hold heat efficiently and protects the cabin from rain, supporting stronger, steadier steam.
Radiata thermo pine, built for outdoors
Clean Nordic timber. Built to last outside.
Unlike ordinary outdoor timber, radiata thermo pine is heat-treated for dimensional stability and long outdoor life. With basic care, Usko is built to stay sound for 25-30 years while keeping its clean Nordic look.
