Expert help that stays with you

Small details become expensive problems once installation begins. We ask the questions early, so a mismatched part, an overlooked requirement or an installation issue gets caught while it is still easy to fix.

Our job does not end when your order ships. We stay available through installation and beyond. If something needs attention, we stay involved, work the problem, and help see it through.

We want you to feel good about choosing Sauna Marketplace long after your first session, and confident recommending us to a friend. That standard guides the advice we give, the products we sell, and the way we take care of our customers.

Sauna and heater customers also receive free shipping on sauna accessories for life.

Planning a sauna, or need help with one you purchased from us? Our founders have built saunas from the crate up and both run saunas at home. New customers and existing Sauna Marketplace sauna and heater owners can Open the 3D planner.

    Thermory 1×4 SHP Thermo-Alder Bench, Backrest, and Skirt Sauna Wood

    Thermo-Alder 1×4 SHP Bench material is a popular choice for sauna benches, backrests, and skirting. This mid-tone is more brown and woodsy looking than thermo-aspen. Great for a more traditional sauna or cottage feel.

    1×4 Bench Boards are an easy and low-cost way to build a premium sauna bench framed with standard 2x4s and decked with these.83″ thick boards horizontally or vertically. See below for our framing suggestion.

      Building Benches Using Standard 2x4s

      This sauna wood is fairly thin and requires dimensional 2x4's to build the frame underneath.  That makes it cheaper, more sturdy, and you can construct it in a way that you won't see the wood. 

      We also like this method becuase there's no tablesaw involved.  

      If you are concerned about light wood showing through, you can use Western Red Cedar 2x4's or paint the 2x4s black using Supi sauna wax or SaunaLife Sauna Wax.

      Include cross bracing every 16" on center.  For extra long spans, consider using 2x6 material for the frame or bracing it from underneath with metal running the full length.

      The recommended gap is at least 1/4" to allow airflow and drainage. It's important to note that wider gaps, up to 3/4" is best for airflow and heat distribution. This is where you'll have to weigh aestetics vs performance.
