S-Series S-870 Infrared Sauna (Corner Unit 3-Person Portable Infrared Sauna)

Picture yourself carving out a calm daily reset in the corner of a bedroom, home gym, or bonus room. The S-Series S-870 Infrared Sauna is made for the person who wants that “always available” at-home routine, but also wants the flexibility to share it. This 3-person portable infrared sauna is space-smart, comfortable, and easy to live with in a real home layout.

If you’re hesitant because corner units sometimes feel like a compromise, this one is built to avoid that. The S-Series S-870 Infrared Sauna is designed with wall-to-wall heat coverage to help eliminate hot and cold spots, so the session feels consistent no matter where you sit. And because it’s rated to seat up to 3, it works as a roomy solo option, a comfortable two-person routine, or a true 3-person portable infrared sauna when you want the full corner layout.

Another common concern is controls and daily usability. This model uses the InfraLogic2 (IL2) control system with Wi-Fi, designed to set and schedule sessions, with the option to extend control to your phone using the mobile app. In everyday life, that means fewer steps between “I want a reset” and actually being inside the sauna.

Space planning is usually the final question, and this is where the S-870 shines. The S-Series S-870 Infrared Sauna measures 51 7/8″ W x 51 7/8″ D x 76 1/2″ H and is explicitly positioned as a corner unit optimized for space efficiency. If you want a 3-person portable infrared sauna that tucks into a corner without feeling cramped inside, this footprint is the point.

Build quality is premium and practical. The cabin uses Canadian Hemlock inside and out, responsibly harvested and sealed with a bio-friendly furniture-grade finish, along with a “Pin-and-Hook” wall locking system for a stable enclosure feel. It is also ETL listed for safety, which is the kind of peace-of-mind detail buyers appreciate when this becomes part of the home routine.

Comfort details are designed for real sessions, not showroom-only features. You get full-sized calf emitters for better lower-body warmth, an in-bench far-infrared emitter, and a matte black metallic floor emitter so your feet stay comfortable. Add the innovative all-glass clear front, elegant LED lighting with 6 color options, and an integrated Bluetooth sound system with heat-resistant speakers, and the S-Series S-870 Infrared Sauna feels open, inviting, and easy to use day after day.

For practical ownership planning: this 3-person portable infrared sauna is inside only and runs on a 15-amp 120V standard outlet (listed at 1710 watts, 15 amps, 120V) with a 6’ cord. Installation requires 3″ side and 5″ overhead clearance. If you are not certain the outlet and circuit are a good match for the dedicated draw, it is smart to have a licensed electrician confirm the circuit before installation day.

Important planning note: Minimum clearance needed for assembly is listed as 83 1/2″, and the manufacturer notes measurements may change over time. Also plan for door swing and access, since the door is all-glass clear with a 90° full swing shown on the drawing.
