The RelaxCube personal steam sauna is exactly what I hoped for! Assembly was straightforward, with clearly marked parts and easy-to-follow instructions. Gloves are included for setup if you prefer to keep your hands powder-free, which was a thoughtful touch. Although it’s a sturdy, full-size unit, it’s still easy to move or fold up when necessary. I also liked how smoothly the double-sided zippers work, allowing easy access from both inside and outside. The steam heats up quickly, and with the adjustable temperature, I can control the heat levels perfectly for a custom session. I set it up in my home gym near my yoga mat, and it’s quickly become my favorite way to wind down after a workout. The built-in thermometer is reliable, so I can easily check the temperature as I go, and the high-back chair is a great bonus for comfort. The ergonomic design supports my neck and back well, which lets me relax fully. I also appreciate the side window that allows me to check my surroundings without breaking the heat seal, keeping the warmth inside while giving a sense of openness. Plus, the size is spacious without feeling overwhelming—big enough for a comfortable steam session but compact enough to fit comfortably in my space. OVERALL - RelaxCube has nailed it with this steam sauna! From assembly to daily use, it’s been a fantastic experience and truly gives that spa-like feel at home. Highly recommend to anyone wanting a high-quality, personal steam sauna.

Steam pod is too small to be 3L 1200 watt and barely reaches 90* in the sauna. Doesn’t perform as advertised. Also no dry pad to put into the floor of the sauna to prevent water build up and mold. No instructions on proper cleaning were provided. Just a page on how to put it together. I’ve had a couple of these and this is the worst one so far.

The sauna is great, unfortunately after my 3rd use the chair has begun to rip at the stitching in the seat.

The RelaxCube sauna arrived well-packaged, and assembly was a breeze. The instructions were easy to follow. The sauna’s size provides plenty of room, and it feels stable and solid once set up. I love how it’s reinforced with extra crossbars, so it doesn’t feel flimsy at all. One thing I really appreciate is the powerful 1200W steamer. It heats up faster than other models I’ve used, and I can feel the difference in how quickly the sauna reaches my desired temperature. Plus, the insulation is top-notch. It retains heat really well, so I don’t have to worry about losing warmth, which makes my sessions more effective for muscle recovery and stress relief. The chair that comes with it is a standout. It’s ergonomic and super comfortable, with great support for my neck and back. I can sit in there for a while without feeling cramped or uncomfortable, which isn’t always the case with other saunas. I also like that it’s easy to control everything from inside the sauna with the remote. The thermometer and the side window make it easy to monitor the temperature, so I can relax knowing everything is running smoothly. And a huge bonus—it’s completely VOC-free, so I feel safe using it regularly without worrying about any harmful chemicals. Overall, I’m really happy with the RelaxCube sauna. It’s sturdy, spacious, and heats up fast. Definitely a great addition to my home wellness routine!

This was a good choice, I’ve used it about 10 times. I set it for 45 minutes and at maximum steam (9). After 30 minutes I turn it down to (8). The temperature gets to 100 degrees Fahrenheit. And the humidity gets to 90%. I weigh 265 pounds and the chair is fantastic, comfortable and roomy. I wipe the inside of the tent down with a towel after I use it, and open it wide so air can flow through the tent. There are hooks to hold the door open and hooks on the other side to wrap the door and 1 wall around the tent to allow it to dry. The whole process takes about an hour. The cell phone holder is really handy since my iPhone is water proof but not steam proof. 3/21/25 after about 20 uses the chair broke. Not a very good quality chair, hopefully the rest of the product is better, especially the steam generator

The very good quality the sauna itself. Very well made and if the roads are fiberglass then this will be long lasting. Same goes for the chair. Because steam causes rust. The only con is the boiler. It doesn't reach 110 °F. because of the height of the Sauna it takes longer to heat up and most of the heat is on top not low where the seat puts you. UPDATE!!! The chair arrived broken. ***2nd Update!!!! Received a replacement. The chair came brand new but after 2 weeks of use the chair again broke. One of the pins from plastic supports for the legs popped out. The chair again ripped in place's of support. The material shreds. The tent is okay but the chair is junk. I might return it again or get a discount. 3rd UPDATE☆☆☆BOILER BROKE.

If you told me I’d be raving about a personal steam sauna in my living room, I would have laughed, but here we are. This thing is a dream. First off, it heats up fast. I’m talking “let me just answer this text while it warms up” fast. The XL size is perfect if you are a normal human who actually wants to move your arms without feeling like a trapped rotisserie chicken. The chair inside is shockingly comfortable. High back, sturdy, and does not feel like it’s going to fold in half the second you get relaxed. I sat in it thinking “wow, this is nicer than half the dining chairs I’ve owned.” The steam output is no joke. In minutes, I was sweating like I just ran a 5K I never signed up for. The zipper keeps the heat in, the whole thing feels stable, and it packs down easy when you are done pretending you are at a high end Nordic spa even though you are 6 feet from your couch. If you want affordable self care that actually works, get it. I feel amazing after every session and honestly I’m mad I waited this long. Absolutely worth it.
