The Ultimate Home Sauna for Full-Body Relaxation & Recovery
Looking for a luxurious, spacious infrared sauna to elevate your wellness routine? The Finnmark FD-3 Full-Spectrum Infrared Sauna delivers the ultimate detox, muscle recovery, and relaxation experience for up to four people.
Engineered with cutting-edge infrared technology, this sauna reaches 170°F in under an hour using advanced UL-listed Spectrum Plus™ and Carbon 360° infrared heaters.
Unlike traditional saunas that rely on intense ambient heat, Finnmark’s full-spectrum infrared technology penetrates deep into muscles and tissues for a more effective detox and sweat session—without overwhelming temperatures.
Built with an antimicrobial Western Canadian cedar interior and a Thermal Plus™ Aspen exterior, this sauna is naturally resistant to mold, bacteria, and warping, ensuring a fresh, long-lasting wellness investment.
With a built-in LCD touchscreen, Bluetooth audio system, medical-grade Spectrum LED red light therapy, and low-EMF, NASA-tested infrared heaters, the FD-3 Infrared Sauna delivers an unbeatable home sauna experience.
