Annapurna – 4 person outdoor sauna

Custom fit and professional installation

Exterior 3D ModelThe Annapurna is a fully insulated, handcrafted outdoor sauna. With a 5’ x 6’ footprint, the Annapurna optimizes smaller spaces yet comfortably holds 4-5 adults sitting or two adults lying down.

Quality craftsmanship and premium materials combine to produce a stunning sauna that excels for comfort and performance in the harshest of weather.

The Annapurna, like all Saunabuilder saunas, is customized to fit the site, cut and constructed on site by a journeyman carpenter.

Although the architectural design work has already been completed, there are several available options for materials and finishing details, including siding, trim and shingles, allowing you to customize the final look of your new sauna. Upgrade options include a cedar cool plunge pool.

Ideal for small residential properties, the Annapurna is guaranteed not to disappoint.

Saunabuilder saunas are not available for self-install.
