Revolutionary Health Benefits
Unlike conventional saunas, our system addresses two major pain points: monotonous discomfort and lack of infrared therapy. The sauna actively releases negative ions to purify indoor air, neutralize allergens/pollutants, and eliminate bacteria, supporting respiratory health while boosting metabolism, cell regeneration, and anti-aging effects. Simultaneously, the integrated medium infrared color therapy lamp penetrates deep into muscle tissue, alleviating aches, enhancing circulation, and accelerating detoxification.
Holistic Wellness Advantages
- Mood Enhancement: Negative ions stimulate serotonin production, reducing stress and combating symptoms of depression.
- Skin Revitalization: Infrared therapy promotes collagen synthesis, improving skin elasticity and combating impurities.
- Weight Management: Deep-heat infrared waves aid calorie burning and metabolic efficiency.
- Pain Relief: Targeted thermal therapy soothes joint inflammation and muscle tension.
The Ultimate Therapeutic Experience
By merging steam sauna benefits with infrared technology and negative-ion air purification, this innovative system delivers unmatched therapeutic results. Step into your personal wellness retreat and emerge rejuvenated—body, mind, and spirit. Invest in lasting health with a sauna designed to evolve with your wellness journey.

Clean interior surfaces every two weeks or after every 5–10 uses with a soft, damp cloth. Leave the door open after each session to allow the sauna to air out and dry. Routine exterior cleaning is generally unnecessary, as the wood is protected with a factory-applied water-based varnish.
Avoid cleaners containing benzene, high-concentration alcohol, or other harsh chemicals, as they may damage the finish. Reapply a compatible water-based varnish to discolored or worn areas as needed.

Customers praised this 3-person steam sauna for heating quickly, easy assembly, and quality materials. Shoppers noted "heats up fast," "easy to assemble," and "worth every penny." The negative ion feature and spacious design were highlights. Some found setup instructions unclear and heating slower than expected.
Hi, my wife and I purchased this product 2 months ago. We use it every night!!! I highly recommend this product. Well put together! Holds temperature well!
We have had our 3-Person Indoor Negative-Ion Steam Sauna | Air Purification & Mid-Infrared Therapy | HKXSC 703ST for several months now. The sauna is used daily. Some days more than once as my entire family loves the sauna and its health benefits. My son says a sauna is not a luxury but a health necessity. :) The sauna gets very hot and steamy. Well constructed. We love the red light and Bluetooth speaker, too.
I highly recommend this product the price was right quality material heats up fast and very easy to assemble. We bought the 3 person and it’s perfect
I ordered this sauna for my wife as a gift. The freight shipping was not bad regular wait. We were so excited. It arrived in a single pallet of several boxes with some gifts and extras, thank you! Assembly was quite simple and their videos were straight forward. Their support team responds within 24hr every time i had a question! I had the misfortune of having my glass door break the next day after i assembled it. Their team was very prompt and professional about getting me a replacement. Their service is amazing! Their product is wonderful. Im delighted to enjoy some sauna time with my wife. Even our kids join us occasionally for a few minutes and everything has been working wonderfully. Before my purchase they had supported me in getting my proper 220v receptacle so all was plug and play ready as soon as it was assembled. Thank you so much HKXSC and team!
We are very excited to have an at-home sauna and thus far we are really pleased with our experience both with the sauna and with the customer service from HKXSC. I was a little bit apprehensive about how the build process would go, but overall it was smooth.
We have sauna for 3 weeks , really enjoying it. Had a slight problem with installation, service was very helpful.
One thing, to put 3 people sauna together need a two people.
I was nervous at first about buying a sauna on the internet, but I will tell you that I have zero regrets. This sauna comfortably seats 3
This sauna has exceeded all my expectations. It heats up quickly, the steam is soothing, and the negative ions really enhance the experience. It’s perfect for two people, and we’ve even fit three comfortably. The build quality feels premium, and I’m already seeing the health benefits in my skin and energy levels. Highly recommend!
I couldn’t be happier with this sauna! It’s spacious enough for two or three people, and the steam combined with the negative ions leaves me feeling refreshed and detoxified. The setup was straightforward, and it looks great in our home. This has quickly become our favorite way to unwind after a long day. Absolutely love it!
The sauna works as advertised and feels very high-end. The negative ions make the air feel fresh, and the steam is consistent. It fits two people comfortably, but three feels a bit tight. The only downside is that it takes a little longer to reach the desired temperature than I’d like. Still, I’m happy with the overall experience.
We love having this sauna in our home! It’s the perfect size for two people, and the negative ions add a noticeable freshness to the air. The materials feel sturdy, and the design fits well with our decor.
This 2-3 person negative ion steam sauna is great for relaxing with my partner or a friend. The steam feels clean and refreshing, and the space is cozy but not cramped. My only complaint is that the instructions for setup weren’t very clear, which made assembly a bit frustrating. Once we got it running, though, it’s been a fantastic way to unwind.
This sauna has everything I was looking for. The spacious design means I can stretch out comfortably, and the negative ions help clear my mind and refresh my body after a long day. Plus, the delivery was prompt and the sauna was easy to assemble
I bought this sauna for me and my two kids, and it’s been perfect for us. The delivery was seamless, and it didn’t take long to set up. The sauna’s spacious interior allows us to sit back comfortably. The negative ion feature helps with my energy levels, and the view through the windows is stunning!
Great sauna for the price. Was able to assemble in about a half hour with 2 people. Was contacted and thanked for purchase a day after ordering and to confirm shipping information.
This sauna combines beauty with functionality. The wood is stunning, and the adjustable temperature settings and LED light strip under the bench are fantastic features. Assembly was straightforward, and the customer service was helpful and responsive. We love our new sauna!
From the moment the sauna arrived, I was impressed with the quality and spacious design. The negative ion therapy helps clear my mind and relieves stress. My friends and I love the wide-open feeling inside — the windows really enhance the experience. Plus, the logistics and delivery were smooth and on time
I’m really happy with this sauna. The space is ideal for three people, and it’s incredibly comfortable. The negative ions make me feel more relaxed and less anxious. Delivery was super fast, and I was impressed with how easy it was to get everything set up. The wide view from inside the sauna is an added bonus!
Received it promptly, well packaged. Wife and I put it together in about 20 minutes. Heats up to 149 in about 40 minutes. We could not be happier with this unit, from all views-functional, aesthetic, and value for the price.
