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 Book a Ben consultation.

    Finnmark Designs FD5 Trinity XL Infrared + Traditional Finnish Sauna Hybrid

    FD-1 FD-2 FD-3 FD-6 FD-7 FD5 Trinity XL Trinity FD4

    We think traditional saunas are the best, but that doesn’t mean infrared doesn’t have benefits. The Finnmark FD-5 Trinity XL is the ultimate in thermal exploration.

    Full-spectrum infrared (Finnmark rates it to 170°F on its own), medical-grade red light therapy, and a Harvia Finnish sauna heater with rocks and built-in controls. A lot of tools at your fingertips.

    Walls are insulated up to 4” thick with mineral wool and a radiant barrier. Western red cedar on the inside, Thermo-Aspen on the outside. Built to the same European standards as the high-end saunas we sell here on the Marketplace.

    5-year warranty. All parts stocked in North America.
