Finnmark FD-3 Full-Spectrum 3-4 Person Infrared Sauna

Stretch out and relax in Finnmark Design’s FD-3 Full-Spectrum 3-4 Person Infrared Sauna. Create a daily wellness retreat in the comfort and convenience of your own home.

Finnmark FD-3 Fullspectrum Sauna

It's the only Low EMF infrared sauna in the industry that combines UL Listed short-wave Spectrum Plus™ infrared(IR) heaters with long-wave Spectrum Carbon 360° IR panels. This allows you to reach temperatures of 170° in less than 1 hour.

The Finnmark FD-3 provides full spectrum IR heat by combining near-, mid- and far-IR heaters. This combination provides higher temperatures, full body coverage, deeper penetration, and a better sweating experience. Each heater is strategically placed to offer the highest level of therapy possible.

Finnmark FD-3

Spectrum Plus™ short-wave IR heaters are tested by UL to be 100% safe. Short-wave IR heaters create deep, penetrating heat--up to 25x more than standard carbon panel heaters. Spectrum Carbon 360° long-wave IR heaters are engineered to produce 360° of pure infrared. Spectrum LED near-IR ceiling lights combine with medical grade color therapy--pick from six different colors, including the new 650nm red light therapy option.  

The anti-microbial Western Canadian Cedar interior resists mold, bacteria, and fungus to keep your sauna free from unpleasant odors. Thermal Plus™ Aspen exterior is organically treated with heat and steam so it won’t rot, warp, decay, or chip. This makes the Finnmark Designs Full Spectrum IR Sauna one of the most durable and longest-lasting saunas on the market

*The infrared panels require at least a 15 amp power outlet. However, for optimal performance Finnmark recommends running them on a 20 amp circuit. While this may cost more up front for installation of the outlet, it will save you money in the long run on your electric bills, and will heat the infrared panels up faster and hotter.


In the USA, the “lifetime” of an infrared sauna is considered 7 years. Many sauna brands offering a “lifetime warranty” know this and use it against you after 7 years of ownership. Your Finnmark Design’s sauna comes with a 10-year warranty, giving you peace of mind that after 7 years you are still covered.

Spectrum Plus™  infrared heaters (UL Listed) have an estimated operational life of 40,000 hours and the Carbon 360° heaters have an estimated operational life of 30,000 hours. Using your sauna 5 times per week, your Spectrum heaters can last up to 130 years. 

The Spectrum Plus™ Incoloy heaters have an unconditional lifetime warranty. No other sauna brand is that confident in their heating elements. 

The Finnmark Limited Lifetime Warranty

Finnmark Designs warrants to the original purchaser (“you”) the following regarding your new sauna, when (a) is installed in accordance with installation instructions provided, (b) is properly and reasonably maintained, and (c) has not been subjected to damage, misuse, or abuse, and (d) is for residential use only (for residential warranty to apply.)
