I purchased the Signature 2 in June 2026. First of all, customer service was great and they explained everything throughout the process. Delivery and assembly was all very easy (you will need 2 people for assembly). The quality of the sauna seems very good and I love using it! The only thing that is bothersome is that it takes a very long time to heat up, I usually have to preheat it for about an hour before use.

The product is well built making it relatively easy to put together. I was disappointed that it did not come with more information on using it: where to start temperature wise, how long to stay at a temperature, more scientific information and less ”how you feel” information about using the different lights. I haven’t really sweated much, and don’t feel much of the benefits listed on the chromotherapy chart. Sorry, I just don’t feel like there’s enough information once you buy the product. There’s certainly a big push that it’s really healthy, but not much information or support once you buy it.

I've been using infrared saunas for more than 20 years, so I've experienced a number of different brands over the years. I can honestly say that my Sunlighten sauna is the best one I've ever owned or used. From the very beginning, the entire experience was exceptional. The purchasing process was easy, and everyone I worked with was knowledgeable, patient, and genuinely interested in helping me choose the right sauna. After the purchase, their customer service continued to be just as responsive and supportive, which made me feel confident that I had made the right decision. The sauna itself has exceeded my expectations. The heat is deep, even, and incredibly comfortable. Every session leaves me feeling relaxed, refreshed, and recharged, and it's become an important part of my daily wellness routine. The craftsmanship and overall quality are outstanding. After using infrared saunas for over two decades, I've developed high standards, and Sunlighten has surpassed them. It's clear they care about both the quality of their products and the people who buy them. If someone asked me which infrared sauna I recommend, my answer would be Sunlighten without hesitation. It's been one of the best investments I've made in my health, and the excellent customer service made the entire experience even better.

Like as much as my previous Signature II

Exactly what I was looking for!

Signature 1 has met my expectations. It is well built and so far no issues.

We LOVE the sauna! It has it's home in our office/study and looks like a piece of furniture. Pleasant to sit in because one entire side of the sauna is a glass door so it feels open...not claustrophobic . The sound system is rich, very pleasant listening whether it be a podcast or relaxing music. We have had the sauna for about 6 weeks....I delayed writing a review until we had put in some serious sauna time. This is what I have learned....Sunlighten has been helpful in answering any questions or concerns we had. The assembly, although not difficult, requires strength to move the four panels due to the ceramic panels in the walls and height to lift the top, ceiling, into place. It definitely increases your "sweat factor" which we know is great for getting rid of toxins. Don't forget to take a towel in with you! Overall, it has been a great addition to our "help our bodies best we can" routine.

Very heavy you must be very strong to move pieces. Impossible to do alone. Does not get hot enough only 135 degrees

Travis was great in helping select the sauna. My only complaint is it takes 50 minutes to get to 110 degrees.

When I'm in the sauna, I am quite relaxed and all my aches and pain seem to go away. I'm very happy with the purchase.

If you're looking for a good quality sauna for your home, you are at the right place. Super easy to assemble. This is better than I dreamed, I can't help but use it every day. The different lights you can choose for each session, the Bluetooth, I set the timer to go on for 45 minutes before I want in, that way it is at the heat I like. A true pleasure!

Very pleased, great quality.

Came cracked and customer made no attempt to return phone calls or emails to make it right.

I am struggling to get it to 150 degrees. I have to preheat it for 1.5-2 hours to get to 135. I’m not sure how to fix the issue.

Works great. Thanks

Works great. Thanks

I love my infrared sauna so much! I am happy we decided to get the 2 person model because I can stretch out. I am 5’3” and a one person would have been too small. I love the Bluetooth, lights, how I feel afterwards; calm and relaxed. It is the best self care purchase I have ever made!
