Description
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 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.
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.
Traditional Sauna Heater Included.
