I-THERA-U 2-Person Sauna Box Review

What it has going for it

What changes in a small apartment

2-person tent. Seats for two people, per the listing, so you don't have to take turns. It also makes the footprint noticeably bigger than a solo tent.

Chair included. The seat comes with it, per the listing, so you can set up and sit down the same evening.

3 L steamer. Steam inside the tent means warmer, wetter air than infrared panels alone. It also means wiping the inside dry and emptying the steamer after each session.

Studio apartment or spare room?

Studio apartment: set up, it takes 71 × 49 × 36 in, per the listing. Folded, it lives in a closet. At 1,400 W, it wants a wall outlet of its own.

Spare room: leave it up and the evening starts with a switch instead of a setup. It is sold for two people. With the steamer, give the room some air and let the inside dry after each session.

Great for you if…

• You want a fabric sauna that two people can use at once
• You like a humid, steamy heat
• You want to adjust the heat without getting up

Skip it if…

• You want to sit in a wooden room: this is a fabric tent
• You don't want to dry the inside after every session
• You'd rather wait for buyer reviews: none are captured for this listing yet

Frame, heat and what's in the box

What the I-THERA-U 2-Person Sauna Box listing names:

• Seats two people
• 71 × 49 × 36 in set up
• 1,400 W
• 3 L steamer
• Folding chair
• Remote control
• Red light lamp (660 nm and 850 nm)

In the box, per the listing: D remote-adjust temperature, Timer settings with one touch.

The manual decides the surface, the outlet and the care routine; it goes before anything above.

Price and availability

On Sep 30, 2026, that price put it around the middle of the 27 portable saunas we have a recent price for.

The button opens the exact listing (ASIN B0GT7Q3CFK), where today's price, stock and seller apply.

A better fit for your apartment?

Cold feet? The SereneLife Portable Sauna Box (8.6/10) has a heated foot pad, per its listing.

No steamer to dry out? The Durherm Portable Infrared Sauna (7.7/10) is infrared only, per its listing.

Our take

The verdict

What we'd buy the I-THERA-U 2-Person Sauna Box for is room for two people, with a folding chair in the box as a bonus. No buyer reviews yet, so this I-THERA-U portable sauna has to win you over on paper. The catch with the I-THERA-U: no word on the top temperature. We'd pick it if you want a fabric sauna that two people can use at once; otherwise, put it next to the Amocane 2-Person Portable Sauna first.
