Finland is internationally recognized for world-class wood construction and advanced wood processing, traditions we proudly continue at OTSO Sauna.

Respect for nature is at the heart of everything we do. Our collections are thoughtfully designed to minimize the use of screws and glue, allowing the natural beauty and integrity of wood to stand out. We avoid plastic entirely in our packaging, choosing recycled cardboard and paper tape instead.

This conscious choice helps reduce plastic waste and protects the natural environments we value so deeply. To further reduce our environmental footprint, our bench elements are delivered as compact components, optimizing transportation efficiency and lowering carbon emissions. Built with durability in mind, OTSO Sauna benches are designed to stand the test of time – both in quality and in style.

OTSO – Strength rooted in nature.

The intelligent PURO bench structure is based on a wooden dowel construction. Each board is fitted with 8 mm wooden dowels at each end, allowing the bench elements to be packed tightly for efficient transport and enabling quick and easy assembly.


Each dowel joint is engineered to carry a load of up to 150 kg, ensuring exceptional strength and long-term durability. This structure also allows the elements to be easily shortened or modified as required.

Bench elements sit freely on the bench
frames for improved ventilation and hygiene. This design prevents water from being trapped between the bench frames and bench boards, reducing the risk of rot or mold. As a result, the benches dry efficiently, helping to prevent unwanted odors and ensuring a healthier sauna environment.

Individual bench elements are connected with through bolts guaranteeing a solid, silent connection. The bench frames are mounted to the walls using stainless steel brackets, which are fixed directly to the wall or to self-supporting bench end elements, offering flexible installation methods.
