Relax Sauna has been making infrared saunas for years, focusing on portability over permanent installation. The FIR9008 is a far infrared portable sauna that sets up in about two to five minutes. That’s the main appeal here: you don’t need a dedicated room or an electrician. You just unfold it, sit down, and plug it in.

The unit heats up in roughly 20 seconds. No pre-heating required. It uses far infrared rays, which are safe and absorbable by the body, to deliver even heat throughout the enclosed space. At 26 pounds and 31.5 inches square, it fits in a corner of a bedroom or home office. The 45-inch height accommodates most users sitting in a standard chair. You can use it for 15 to 30 minutes daily to promote sweating, which helps discharge toxins like heavy metals, and may support metabolism and circulation over time.

The build feels functional but not luxurious. The fabric is durable and the zippers work smoothly, but the frame is lightweight and can feel a bit wobbly if you shift around. It’s best for someone who wants the health benefits of a sauna without the space commitment. If you’re after a premium spa experience, this isn’t that. But for daily detox and relaxation in a small apartment, it gets the job done.
