The Relax Black Pro is a portable far infrared sauna designed for single-person use with higher-frequency durability. This is a foldable tent-style FIR sauna powered by dual 700W ceramic semiconductor radiator generators, operating on standard 120V household power, with a 7–14 micron far infrared wavelength range. The Black Pro uses a thicker, reinforced insulated tent material with a silver-lined interior and embroidered logo, which delivers faster heat-up (3–5 minutes vs. 5–8 minutes on the Silver Elite) and a shorter recommended session time of 15–17 minutes. It ships as a complete kit including a folding chair. No installation required.
Why This Portable Far Infrared Sauna
- Reinforced insulated tent with silver-lined interior — thicker, heavier-duty material compared to the Silver Elite; silver lining increases heat retention for faster heat-up and more consistent operating temperature.
- 3–5 minute tent heat-up — faster than the Silver Elite (5–8 minutes) due to the denser insulated material.
- Dual 700W FIR radiators — two ceramic semiconductor radiator generators, 1,400W total; 7–14 micron far infrared wavelength range; FIR emission is instant at power-on.
- 120V standard plug-in — runs on any standard US 120V household outlet; no dedicated circuit, no electrician, no installation.
- Higher-frequency durability — construction rated for up to 15–20 sessions per day; suitable for household environments with multiple daily users.
- Complete kit — folding chair, dual FIR radiator towers, support poles, digital controller and stand, two washable foot pads, and canvas carry bag all included.

Common Questions
Does the Relax Black Pro portable far infrared sauna require any installation or special electrical setup?
No. The Black Pro plugs directly into a standard 120V US household outlet. No dedicated circuit, electrician, or installation is required.
Is a chair included?
Yes. Every Black Pro ships with a heavy-duty folding nylon chair rated to 220 lbs. If you weigh over 220 lbs, the manufacturer recommends substituting a heavy-duty metal folding chair covered with a towel.
How long does it take to heat up?
FIR emission begins the moment the unit powers on. The Black Pro’s reinforced insulated tent reaches full operating temperature in 3–5 minutes — faster than the Silver Elite (5–8 minutes) due to the denser insulated material.
What is the difference between the Black Pro and the Silver Elite?
The Black Pro uses a thicker, reinforced insulated tent with a silver-lined interior and embroidered logo, delivering faster heat-up (3–5 min vs. 5–8 min) and a shorter recommended session time (15–17 min vs. 20 min). The Black Pro is also slightly deeper (33" vs. 32") and both weigh 33 lbs. Both use the same 1,400W dual FIR radiator system and ceramic chip technology. The Black Pro is rated for up to 15–20 sessions per day; the Silver Elite is designed for personal and family home use.
Can this sauna be used commercially?
The Black Pro is rated for up to 15–20 sessions per day and is suitable for high-frequency household use. However, unapproved commercial use on residential-spec models voids the manufacturer’s warranty. Contact us at support@luxuryzenliving.com before purchasing for commercial deployment.
