The Saltbox Sauna takes its form as a modern interpretation of one of New England’s most enduring rooflines. Designed for use in coastal homes and maritime buildings, the saltbox profile provided the ability to shed snow and resist heavy winds with a simple, asymmetrical roof. Clad in our flagship Weathered Grey Cedar, the Saltbox Sauna carries forward this iconic profile, providing a structure that will weather gracefully over time while maintaining a purposeful, timeless presence.
Within, the Saltbox features our largest sized standard interior heating room, comfortably seating six with the introduction of our thoughtfully designed L-shaped bench seating. Surrounded on all sides by glass, the interior space provides close connection to the landscape. On the exterior, standard Harbor antique brass fixtures tie together our vision for blending the centuries-old practice of sauna with the maritime heritage that has long inspired our work.
A HUUM HIVE 12kW electric heating element warms the interior space. Exceptional heat retention is ensured by using ROCKWOOL insulation with a vapor barrier. Ventilation follows traditional principles and is achieved passively from the floor, with airflow exiting through a sliding vent under the top bench.
Just like the structures that endure in coastal regions, we envision the Saltbox aging timelessly with purpose over the decades ahead.

Featured Exterior Treatment
Weathered Grey Cedar
Our standard Saltbox Sauna is clad in cedar that has been treated in a hand-selected exterior finish that echoes the natural silvering process found across coastal architecture.
Just as wharf buildings and boathouses quietly weather to a timeless grey over decades of exposure, this treatment provides the look immediately while ensuring long-term performance in the elements.

How do I prepare my site for delivery?
There are several options to choose from to prepare your site prior to delivery. We recommend preparing a level pad of either stone or concrete in the area you want your sauna to be placed upon delivery. The size of the site will vary based upon the footprint of the model you purchase. Depending on proximity to the closest power source, installing a power line may also be required.
We recommend consulting with a local contractor or 3rd-party site prep service to ensure this is done correctly prior to delivery.
If you wish for your sauna to be placed in a difficult or precarious location, a more involved site prep and service involving cranes and additional team members may be necessary. Please let our team know if feel your delivery site may fall outside the normal installation scope and we will coordinate with you prior to delivery.
At this time, our team is unable to perform site preparations ourselves. Please consult our Site Prep Guide for more details on site requirements for your sauna.

How do I clean and maintain my sauna?
We designed our saunas to age in the outdoors and harsh environments without any necessary cleaning and maintenance. If the event that you wish to provide supplemental or periodic treatment to the exterior of your sauna, please consult our Cleaning & Maintenance Guide.
If you wish to clean the interior benches or floor of your sauna after personal or guest use, you can easily clean your sauna by wiping down with either a damp cloth or sponge with a mild soap, avoiding any products containing strong or harsh chemicals. You may wish to do a more thorough cleaning once a year.
