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.

RED LIGHT THERAPY

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.

Finnmark FD-1 Construction

The 2-person infrared sauna from Finnmark Designs uses high-quality materials for both aesthetic appeal and durability. The interior is constructed with Western Canadian Red Cedar, valued for its antimicrobial properties, aromatic quality, and natural resistance to decay. The cedar is clear meaning it is knotless.

The exterior is made from Thermal Plus™ Aspen, which is known for its stability and resistance to warping, rot, and decay, making it ideal for long-term use in saunas. Thermal Plus means the Aspen has gone through a thermal modification process that makes it withstand high temperatures. These materials create a natural and luxurious environment, enhancing the sauna's overall longevity and performance.

The FD-4 has fully insulated walls for maximum heat retention.

Frequently Asked Questions

How many people does the Finnmark FD-3 sauna fit?

The FD-4 comfortably fits two people, with ergonomic seating and infrared heater placement optimized for shared use.

What makes the Finnmark FD-3 different from other infrared saunas?

The FD-4 combines a powerful infrared heating system, including UL-listed infrared heaters similar to Spectrum Plus™, with a traditional sauna heater/steam element, offering a unique hybrid experience that blends deep-penetrating infrared heat with classic hot-air and steam sauna benefits.

This hybrid design delivers a versatile range of heat sensations that go beyond what conventional infrared saunas can provide

How quickly does the sauna heat up?

The FD-4’s infrared system can reach up to 170 °F in less than an hour using its UL-listed infrared heaters on a standard household outlet, and when the traditional sauna heater is also engaged, it can produce even hotter steam-based heat (up to 190 °F) more quickly

It also includes traditional sauna elements (steam/heat generated from the rock heater), giving a hybrid heating experience that can combine the subjective comfort of infrared with the intensity of conventional sauna heat.

Benefits supported by full spectrum infrared & traditional steam technology include:

- Increased circulation and improved heart health
