The Thera360 Plus is Therasage’s flagship product and the one most independent reviewers point to first: a portable infrared sauna at $1,428 that packs full-spectrum infrared, red and near-infrared light, tourmaline heating panels, and a grounding mat into a 24-pound folding unit. I went through the official spec sheet and a detailed independent review to see if it earns that reputation.
What it’s made of
The panels use natural tourmaline gemstones to generate negative ions while delivering full-spectrum (near, mid, and far) infrared wavelengths, rated at 98% emissivity. Two Tri-Lite red and near-infrared panels add light therapy on top of the heat. The unit runs on 900W, adjusts from 100°F to 170°F in 5-degree increments, and includes a 90-minute timer.
Therasage builds the shell from non-toxic bamboo with no VOCs, and the whole thing is rated for both 110V and 220V outlets. A grounding mat and EMF, ELF, and RF shielding round out the feature list, which is more than most portable saunas in this price range bother including.
What buyers and reviewers are actually saying
Biohacker and reviewer Michael Kummer, who has tested full cabin saunas and infrared blankets, rated the Thera360 Plus 4.9 out of 5 and called it “one of the best infrared saunas on the market.” His main praise: it gets “incredibly hot” and reaches temperature within about 15 minutes, weighs only 24 pounds with a carrying case included, and costs a fraction of what full-size cabin saunas run while offering comparable heat and light therapy.
He also noted a few real downsides. It fits one person at a time, you can’t stretch out or recline inside it, and he reported the fiberglass support rod occasionally detaching during use. It also needs floor space set up unless you fold it away after each session.
Size, setup, and daily use
Set up, the sauna measures 33″ x 33″ x 46″, roughly the footprint of a small chair when open. It folds flat with a carrying bag for storage between sessions, which is the whole point of a portable sauna over a cabin unit.
Most users start with 20 to 30 minute sessions a few times a week and adjust the temperature up as they acclimate. Kummer noted that having it easy to set up in a spare room, rather than dedicating a permanent space to a full cabin, “dramatically increased” how often his household actually used it, including his kids using it on their own. For general tips on getting more sessions out of any Therasage device, see my care and usage guide.
How it compares
Against a full-size cabin sauna, the Thera360 Plus trades room to stretch out for a fraction of the price and zero installation. Against other portable infrared brands, the combination of full-spectrum heat, red light, grounding, and EMF shielding in one unit is unusual. I compared Therasage’s approach to a direct competitor in Therasage vs HigherDOSE, and rounded up how it stacks against the rest of the Therasage catalog in my how-to-choose guide.
Should you buy it
If you want the fullest version of Therasage’s infrared and red light technology in a single portable device, and $1,428 fits your budget, this is the product independent reviewers rate highest in the entire catalog. If you’re not ready for that commitment, smaller products like the Tri-Lite panel or TherAid wrap let you try the technology for under $250.
Before you order, buy only from Therasage’s official site or an authorized retailer so your warranty is valid, and read the return terms since sauna products can take longer to process than smaller items.
