We recommend that you start by considering the number of people you’d like your sauna to accommodate. Outdoor saunas start at a capacity of 2 people and can by 6′ x 4′ or 7′ x 6′. From there they just get longer, with some saunas including porches and change rooms, they can get very long reaching 12′ or 16′ feet. But the most common footprint is 7’x7′ or 6′ x 6′. Let us know how much space you have and we will find the right option for you.
