Sisu Saunas

Finnleo’s Sisu series has become a classic of the sauna world. True to tradition, Sisu saunas are made in the Finnish style of exclusive fine-grained Nordic White Spruce — you’ll even notice a subtle scent of deep Finnish forests. Sisu — a clean, pure expression of sauna at its genuine best.

The Essence of Sauna

Free-standing Sisu saunas glow with genuine welcome. The room itself is light and well-ventilated. The wood for walls and ceilings is Nordic White Spruce (European Grade A from sustainably managed Finnish forests) or optional clear Western Red Cedar or premium Canadian Hemlock. The subtle scent of a Finnish forest combined with Scandinavian design provides a pure sauna experience.

Sisu saunas offer unlimited options, from personal size saunas to large club size saunas, making them equally ideal for private or public use. Custom designs and sizes are available as well, and interiors, windows, doors and much more can be personalized with a wide variety of options.

Abachi 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.
