Bought this in Feb and put in our garage. It would only get to 88-90 degrees and took 45 min to warm up. The garage always stays 60-70 degrees when it is below freezing so we didn't feel like it was having to work too hard. It was never used in the summer so it may have been more efficient in warmer weather. After reading the reviews we added a second humidifier and it works great! Stays about 102 when on the highest setting. Also only takes 10 min to warm up now. Currently it is about 37 degrees outside and about 60 in the garage when it is getting to 102.

I love a good steam and this is everything. This thing gets super hot and is just perfect. It took about 10 minutes to put together and it works exactly like any good steam room. I would recommend getting some good filtered water, set it on high, and give it about 15 minutes. Dive in and prepare to sweat. It is so good. I couldn’t be happier. Highly recommend.
Update: So I have been using this portable steam room for about two weeks now and it is still dynamite. I worry a little about the main zipper. The fabric is stretched pretty tight which causes the zipper to get snagged in spots. It is fine, just be careful. Otherwise, this really is a game changer for me. Used it today, post workout. My sinuses love me right now and winter has begun, so I am super thankful for finding this.

As a 5’10” gym rat who lifts 4x a week, I was skeptical of “cramped sauna” complaints – but this 35”x35”x68” model has plenty of room to stretch out post-workout. The folding chair feels sturdy under my 180lbs (no sagging at all), and the zipper glides smoothly every time (no tools needed to open/close). The steam stays locked in (zero leaks, even after 12 uses) and the 9 heat levels let me dial in the perfect intensity for muscle recovery. Way cheaper than spa visits, and my post-lift soreness fades way faster now. Total budget-friendly win

So assembly is actually quite easy. 3 minutes is a bit over optimistic, it took me about 10 minutes to assemble all the poles and get the fabric over the frame. I recommend laying the frame on its side as it makes it much easier to get the zippers closed. Mine was a very tight fit and I had to do a bit of stretching to ensure the zippers did not rip at the seams when closing it up. Once zipped up mostly, getting the entry door fully zipped can be a bit of effort when in the sauna. Perhaps the fabric will stretch a bit over time, but initially it is a VERY tight fit.The provided chair is handy, but not very comfortable. A pad for the seat is a good idea as it will make long term sitting much more comfortable. And the back is low so if you want to ease back and rest your head, you will need a different chair. It's nice that one is included, but it's not ideal for long term comfort.The steamer works really well. It heats up the water quickly and the sauna starts to come up to a very comfortable temperature in about 5-10 minutes. The display is a simple 3 number display, the first 2 numbers represent the timer in minutes, and the 3rd number is the temperature setting from 1-9. There is nothing in the manual describing the temperature ratings of each setting, so it will be trial and error to find the right setting for you.They call this portable, and it can be moved around pretty easy since assembly is pretty quick, but without a carry bag you would have to arrange to tote it around somehow. I'm also a little dubious of how well the zipper would hold up if it was constantly being assembled and disassembled. I'd set it up and leave it.It does keep the steam in the sauna and the temperature remains constant. While it looks small, its actually pretty comfortable, and the experience of using it was quite relaxing. The chair got uncomfortable after about 10 minutes so I'll need to find a pad, but otherwise is works as advertised.

I’m was worried about feeling cramped, but the size gives me plenty of room to sit back comfortably—no squeezing at all. The dual-head explosion-proof zipper works smoothly every time, even after 15+ uses, and the heat resistance is solid (never had any warping). The 1500W steamer heats up fast, and the 9 heat levels let me adjust to my preference—perfect for unwinding after a long day. The built-in pocket is super handy for my phone, and it folds up compactly to store in my closet. Way better than paying for spa trips—worth every penny!

Living in a tiny studio, I needed something compact and functional – this sauna checks both boxes. Setup takes 3 mins, and it folds down small enough to tuck in my closet when not in use. I was worried about steam leaking (per some reviews) but the insulation works great – zero steam escapes, so my apartment doesn’t get humid. A quick wipe-down after each use keeps it odor-free (no lingering weird smells), and the chair feels sturdy when I unwind after evening walks. So convenient to have spa-level detox at home!

I’ve already used it 20+ times. I have plenty of room to sit back. The chair stays stable, the zipper glides smooth, and the insulation locks in steam perfectly—zero leaks, even after 30-minute sessions.It heats up in 10 mins, has 9 adjustable heat levels for post-workout relief, and folds down tiny to tuck in my closet (ideal for my budget apartment). No gym membership fees, no spa commute—just solid, reliable sauna benefits at a fraction of the cost.

Good materials for the price.

1500W heats in minutes and the 4L tank lasts through multiple sessions. I usually do two shorter steams before needing a refill, which is super convenient.

Bought this for winter nights and it’s become my routine. The tent keeps heat in, the outside stays pretty dry, and cleanup is basically just a quick wipe.
