True to tradition, Finnleo saunas are made in Finnish style exclusively of fine grained Nordic White Spruce. Sisu rooms are light and well-ventilated, with a subtle hint of deep Finnish forests. The extensive use of Abachi white wood makes it comfortable to the touch even at high temperatures. Abachi has no knots or splinters and resists stains as well as odor absorption. Pamper yourself with the soft, even heat from Finnleo’s exclusive heater design. Direct contact between the elements and rocks eliminates the harsh metallic feel characteristic of lower-quality heaters.

The Essence of Sauna

Sisu saunas glow with genuine welcome. The room itself is light and well-ventilated. The wood for panels, frame and flooring, in Nordic White Spruce or optional clear Western Red Cedar or premium Canadian Hemlock, is clean, unpretentious, strong — a perfect frame for the pure sauna experience.

Beautiful and Functional

Abachi wood is used extensively throughout the sauna — wherever skin touches wood — on benches, backrests, head rests and door handles. Abachi wood remains comfortable to the touch even at high temperatures, resists stains and odor absorption, and has no knots or splinters. It is the ultimate sauna bench material and is used in the finest saunas of Europe.
