Finnmark FD-4 Trinity Infra-Steam Sauna

Finnmark FD-4 Trinity Infra-Steam Sauna

The Trinity Combination Sauna is the only sauna available that combines Finnmark’s UL listed Spectrum Plus infrared heaters combined with a traditional 120V sauna heater, plus true medical grade Spectrum Red Light™ Therapy.

No need to compromise. Finnmark’s FD-4 Trinity is the only combination sauna with true UL listed infrared heaters together with a traditional sauna heater. Furthermore, the IR panels, red light therapy, and the traditional sauna heater are all powered by a standard 120V and can be plugged into a common outlet, so no electrician is needed. Get all the benefits of infrared combined with traditional rocks with steam.

Get hot fast! The only IR heaters that have passed the rigorous tests from Underwriter Laboratories used in tandem with a traditional steam sauna stove. Short wave far-infrared penetrates muscles, joints, and makes you sweat 25 times more than carbon panel heaters. The traditional 1.9kW sauna heater lets you splash water onto the rocks for an authentic steam sauna experience. Enjoy the benefits and the intensity only offered by a steam sauna.

Red light therapy is a type of phototherapy that uses low-level light wavelengths to penetrate the skin and stimulate the production of collagen and other proteins, which can lead to numerous potential health benefits. It’s a perfect enhancement to your sauna wellness ritual.

Ships from a US warehouse — no overseas wait.

Health Benefits

• 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.
