Finnmark Designs FD5 Trinity XL Infrared Traditional Finnish Sauna Hybrid

Pre-Order Now. Ships by Late August 2026. Finnmark IR Cabins are backordered at the factory level. This applies to all retailers, not just us. No one will deliver a Finnmark sauna faster than Sauna Marketplace. New orders ship on or before August 28th. Beginning in September, Finnmark expects to maintain regular stock levels. Pre-Order Bonus (through July 31): Every order includes a complimentary curved backrest and sauna cleaner, automatically added. No code needed. We’re also holding 2025 pricing through August. Questions? We’re a small team and happy to help. Just reach out. 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 (the only IR technology we trust, capable of 170°F on its own, the highest in the industry), 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. 10-year warranty. All parts stocked in North America.
