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.

What’s Included
Customers said this outdoor sauna heats up excellently and is relatively easy to assemble with just two people for the first wall and ceiling. One customer had shipping damage to the roof box, but replacement arrived within 7 days. Initial performance has been positive.
I have a 4 person outdoor sauna that I set up 2 weeks ago. I only needed two people for the first wall and the ceiling. It is super hot. My roof box was damaged by shipper, a new roof arrived in about 7 days. so far so good.
We love our new sauna! It has all the features that other units miss. It has infrared/ red light therapy, negative ion production but most importantly, it has the volcanic rocks & stove of a traditional sauna. One label of distilled water increases the humidity & the apparent heat. This really brings on the sweat. For a full steam bath we just attach the steam generator to the Sauna inlet & voila, it is now a steam room. Having it by the pool, hot tub & outdoor shower brings the full “Spa” experience to our outdoor area. With the optional cover it is protected from fading in the harsh Florida sun & keeps it all looking great when family visit. Assembling the unit was a breeze. With my wife’s help, it took us less than 1/2 a day from arrival to working. The side pieces just clip together and a simple screw gun locks the pieces in place. I would highly recommend this unit if you are looking for a personal Sauna as it has so many more features that others do not.
Just as advertised. Fairly easy installation. Would highly recommend.
I can’t say enough about this sauna! Delivery was quick, and the quality is truly outstanding. The appearance exceeded my expectations, and the size is perfect—spacious, comfortable, and absolutely beautiful in the yard.
Setup took about five hours with two helpers, and everything is designed with impressive craftsmanship. The heating is fantastic, and every detail feels high-quality. I use the sauna daily and have zero regrets—definitely the right decision!
I highly recommend this sauna to anyone. I did extensive research before purchasing, and it absolutely paid off. It’s affordable, reliable, and worth every penny. I’m so grateful for such a great product!
We just love it! Easy set up we were using it the next day. Love all the health benefits we are getting. We highly recommend it!
we were close to a supply outlet in southern california and were able to see the sauna. the girl in riverside was very accommodating, they did free delivery to fallbrook california
and set it up for a very reasonable fee. everything works great thus far.
This.
Song is everything they promised.It works perfectly and the wife and I love it.We go back and forth between the pool and the sauna.
Vary well built. Very nice👍
I have been wanting a steam outdoor sauna for a long time. Finally modifications to my house created an ideal place for ne - on a small porch ust outside my wife's and my bedroom. We have been using is almost dfaily with great joy. And, with help it was fast and easy to assemple, looks great, was amazingly inexpensive, and has already convincved several friends that they too should purchase one.
Since buying the sauna, my family has been using it at least three times a week, and it seems to have kept us warm this winter. We're already addicted to it. It feels so good to feel my tense muscles loosen up. Because I love the sauna so much, I clean it often and take good care of it. One tip: using a sauna diffuser seems to help relieve fatigue better.
Absolutely amazing! Easy to assemble and is a game changer!
Easy to put together, heats up in about 30 min. looks great in our space.
