Finnmark FD-4 Trinity Infrared & Steam Sauna Combo

The Ultimate Combination Sauna Experience

Discover the unparalleled features of the Trinity Combination Sauna, a sauna that stands alone in its versatility. It's the only sauna on the market that seamlessly integrates Finnmark’s UL-listed Spectrum Plus infrared heaters, a traditional 120V sauna heater, and authentic medical-grade Spectrum Red Light™ Therapy.

No Compromises Necessary

With Finnmark’s FD-4 Trinity, you don't have to make sacrifices. This exceptional combination sauna boasts genuine UL-listed infrared heaters in tandem with a traditional sauna heater. What's more, all these components operate on standard 120V power and can be conveniently plugged into a regular outlet, eliminating the need for an electrician. You get the best of both worlds: the benefits of infrared combined with the traditional steam experience using sauna rocks.

Experience Rapid Heating

Our Trinity sauna features IR heaters that have passed rigorous Underwriter Laboratories tests and work harmoniously with a traditional steam sauna stove. Short-wave far-infrared technology deeply penetrates muscles and joints, inducing a sweat 25 times more effective than carbon panel heaters. For those who love the ritual of splashing water onto hot rocks, our 1.9kW traditional sauna heater provides an intense and luxurious steam sauna experience.

Enhance Your Wellness

Red light therapy, a form of phototherapy, employs low-level light wavelengths to penetrate the skin and stimulate collagen and protein production. This therapy offers numerous potential health benefits and serves as the perfect complement to your sauna wellness routine. Experience the next level of relaxation and rejuvenation with the Trinity Combination Sauna.

Benefits of Infrared:

  • The technology of the Spectrum Plus incoloy heaters warms your core body temperature, producing a cleaner, healthier sweat while lowering blood pressure, and maintaining heart health.
  • The natural heat produced by the Spectrum Plus heaters is designed to achieve a more controlled hot climate much like a traditional sauna without the unbearable heat temperatures. This deeper penetration through sweating goes beyond the muscle and fat rather than a traditional or hot air sauna.  As a result, you're able to work up the best possible sweat in the least amount of time.
  • Spectrum Plus heaters remove 17% more toxins such as cholesterol, fat-soluble toxins, toxic heavy metals, sulfuric acid, sodium, ammonia and uric acid.
  • Full Spectrum Sauna combination of long-wave Spectrum Carbon 360 infrared panels with UL-listed short-wave Spectrum Plus™ infrared panels. This combination provides higher temperatures, full body coverage, deeper penetration, and better experience than any other sauna.
  • Reap the benefits of a more natural pain relief remedy with every infrared sauna session.
  • Athletes can appreciate a faster muscle recovery with increased blood flow to the muscles, delivering more concentrated oxygen and creating more energy to heal.
