1,200 W of heat

That's the power the listing states, steamer included. Give it a wall outlet of its own, never a power strip or an extension cord.

What it has going for it

What changes in a small apartment

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.

15 heat levels · 90-min timer · remote. You change the heat and the time from inside, per the listing, without unzipping and letting the warmth out.

Studio apartment or spare room?

Studio apartment: set up, it takes 71 × 32 × 32 in, per the listing, and it goes up without tools. Folded, it lives in a closet. At 1,200 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. With the steamer, give the room some air and let the inside dry after each session.

Great for you if…

You like a humid, steamy heat
You want to adjust the heat without getting up
You need the sauna to disappear into a closet after use

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

What I-THERA-U promises

The seller states, word for word, in the I-THERA-U Portable Steam Sauna (3L 1200W) listing:

Our portable steam sauna comes with a 3 L & 1200 Watt high-power steamer can generate steam quickly, the waterproof & thermal insulation fabric can locks in warmth.
Its waterproof inner material is easy to wipe dry, keeping it clean and comfortable for every use.
Equipped a high load-bearing foldable chair, features both interior and exterior pockets.

Their words and their figures, not our measurements. We leave out health promises, even when a listing makes them, and any low-EMF figure stays the seller's.

Frame, heat and what's in the box

What the I-THERA-U Portable Steam Sauna (3L 1200W) listing names:

71 × 32 × 32 in set up
1,200 W
3 L steamer
Folding chair
Remote control
15 heat levels
Timer up to 90 minutes
Tool-free setup
Red light lamp (660 nm and 850 nm)

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

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.

Two of you? The Amocane 2-Person Portable Sauna (5.6/10) is sold for two people.

Our take

The verdict

Our favourite thing about the I-THERA-U Portable Steam Sauna (3L 1200W) is a folding chair in the box, closely followed by a 3 L steamer. No buyer reviews yet, so the I-THERA-U Portable Steam Sauna (3L 1200W) has to win you over on paper. The catch with this I-THERA-U portable sauna: no word on the top temperature. We'd pick the I-THERA-U if you like a humid, steamy heat; otherwise, put it next to the iDOTODO Full Size Portable Sauna first.

Living with it

Setting up

No tools needed, per the listing. Open the frame, zip the cover on, unfold the chair, then plug it into the wall.

A session

The remote lets you change the heat from inside, and the timer runs up to 90 minutes. Keep a towel and a glass of water within reach.

Afterwards

Empty the steamer and wipe the inside dry. Let it air out before you fold it away, so it smells fresh next time.

The one thing we'd check first

One thing to settle before the I-THERA-U Portable Steam Sauna (3L 1200W) ships: check the floor space, because it takes 71 × 32 × 32 in once it is up, per the listing, plus room to zip in and out.

Before you buy

The floor space

Tape the footprint on the floor and leave a clear strip to step in and out. Our placement guide has the clearances.

The outlet

It draws 1,200 W, per the listing. Plug it into a wall outlet you trust, never an extension cord. Our 110 V vs 240 V guide explains what to read on the label.

Who it fits

Fabric tents are sized for sitting; check the height and the head opening against the tallest person who will use it.

Where it lives

With a steamer, the inside needs drying after each session before you fold it. Decide where it goes folded, and read our wood vs fabric guide if you are still torn between fabric and wood.

Frequently asked questions

Is the I-THERA-U Portable Steam Sauna (3L 1200W) any good?

We rate it 5.5/10 (fair). The rating comes from its documented listing alone, as no customer-review record is captured yet.

What outlet does the I-THERA-U Portable Steam Sauna, 3L 1200W need?

We found no voltage in the listing. Read the electrical requirement on the listing and in the manual before you order: some cabins plug into a standard household outlet, others want a dedicated circuit. Anything beyond an existing standard outlet is a job for a licensed electrician. Our sauna size planner checks the floor space.

What do you get with the I-THERA-U Portable Steam Sauna (3L 1200W)?

Its listing states a folding chair in the box, a 3 L steamer, 15 heat levels and a 71 × 32 × 32 in footprint. These are the seller's figures, not our measurements: how warm it really gets on a cold evening and how sturdy the frame feels can't be read from a listing.

What should I check before ordering the I-THERA-U Portable Steam Sauna (3L 1200W)?

The floor space: tape the footprint on the floor and leave a clear strip to step in and out. Our placement guide has the clearances. The outlet: it draws 1,200 W, per the listing. Plug it into a wall outlet you trust, never an extension cord. Our 110 V vs 240 V guide explains what to read on the label. Who it fits: fabric tents are sized for sitting; check the height and the head opening against the tallest person who will use it. Where it lives: with a steamer, the inside needs drying after each session before you fold it. Decide where it goes folded, and read our wood vs fabric guide if you are still torn between fabric and wood.

Where can I buy the I-THERA-U Portable Steam Sauna (3L 1200W)?

We link to the exact listing on Amazon, where today's price, stock and seller apply. It is an affiliate link, and it has no effect on the rating.

Have you used the I-THERA-U Portable Steam Sauna (3L 1200W) yourselves?

No, we haven't used it ourselves. Everything on this page comes from its listing, read line by line and weighed with our published formula.
