The Relax Black Pro is a portable far infrared sauna that delivers deep, penetrating far infrared warmth in a compact, easy-to-use design — the experience of a full sauna session in any room of your home.

The Black Pro features an upgraded, thicker, reinforced tent material lined with silver on the inside for enhanced reflectivity and heat retention. The result is faster warm-up times, greater heat intensity, and better overall efficiency — built for frequent, heavy use, including professional settings where the sauna may run 15–20 sessions per day. Its superior insulation also allows for shorter sessions at the same heat intensity.

Silver Elite vs. Black Pro: both models use the same patented dual FIR conductor system, so the core heating elements and infrared output are identical. If you need a sauna built for frequent, heavy use with faster heat-up times and enhanced durability, the Black Pro is the better investment.

Please note: current inventory features the Relax legacy logo on the tent. Same technology and trusted quality — an updated logo is coming soon.
