Easy Assembly & Factory Tested

Easy Assembly

All Sun Stream saunas include an invisible fastening system where the panels simply slot together to create a solid connection. Installation is quick, easy and requires only a screwdriver to fix the handle to the door along with a couple of additional minor tasks. There are no special electrical requirements. Depending on the model purchased, installation can take anywhere from 30 – 90 minutes. Almost all of our customers install their saunas without an issue, however should you be unable to carry out this task due to age, health restrictions or the fact that you just can’t be bothered, please contact us for an installation quote.

After doing some research on IR saunas I ended up choosing a SunStream Evolve 20. It was much better value than some of its competitors. The sales guys were very helpful with any questions I had and didn't push me into making a purchase. I wasn't sure whether to go for the mini the 10 or the 20, but I'm glad I went for the 20. I still use it as a one person sauna but its nice to have extra space if your budget allows for it and your room can accommodate it. Assembly was fairly straight forward but it is a two man job. I am using the sauna pretty much every day and the benefits to me are general relaxation and increased recovery from workouts. Once I turn on the power it is already pretty hot within 15 minutes and then I go in the sauna. I am sweating profusely after 10 minutes...

Great communication - prompt, clear and always helpful. Managed to visit a local ‘Health and well-being Centre’ who had recently purchased the Evolve 20 - tried out the sauna and had a really helpful chat with the manager. Great experience and all positive. Installation was fine but definitely needed two people as some parts are quite heavy. Have been using it regularly now for a few weeks and really happy with everything.

Very nice professional experience with the people from sun stream saunas. I am loving my infrared sauna and quality is fantastic. Don’t let the the flat pack scare you as it was super straight forward.

Had the sauna for about a year now and I love it. I use it atleast twice a week, some times more depending on shifts. It was easy to put together, looks great and hasn't given any issues since we got it. I would highly recommend.

When I moved from USA to Europe I was looking for an alternative to a hot tub I had used for years. Not having the room I looked for an alternative and after much research I discovered Sun Stream Saunas. After a couple of emails back and fourth. I placed an order knowing that they were waiting for new stock to arrive. When the new stock arrived at the warehouse, I promptly paid the balance and my Sauna was shipped and arrived 7 days later. Service from my initial inquiry through install and use has been spot on. I highly recommend their product.

I finally bought the Evolve 20 after months and months of research. I am so delighted with it. Sun Stream customer service was brilliant and the sauna itself is amazing. My only regret is not buying it sooner! It arrived well packaged and was easy enough to put together with the detailed instructions. It is excellent quality, very well built.

Best infra-red sauna on the market!

Sun Stream was great to deal with, my sauna arrived only after a week and was very easy to out together. Myself and my wife are now using the sauna all the time, which is great to clear the head after a poor night's sleep with 2 small boys 🙂 Finally, I can't believe the level of sweating I get after a 20 min session. Highly recommended!

We searched for a low EMF sauna with no chemicals in materials (such as particle boards or plywood). I'm really impressed with the quality of Sun Stream sauna which is good value for the money invested. The sauna was delivered from the UK to the Czech Republic without any problems within a couple of days. Also, the setup was very easy. Thanks for the great service!

Fantastic experience with Sun Stream! We did a lot of research about infrared saunas before making our purchase and we are so glad we went with Sun Stream. The ordering process was easy and customer service throughout was spot on. Delivery and assembly was seamless. We have been using our sauna for over a year now and love it. We use it almost daily and it is a quality product, requires almost no maintenance and is very easy to use. Highly recommend Sun Stream Saunas!

Customer service is outstanding. They kept us fully informed of the delivery status and the sauna (Evolve 10) was delivered on the scheduled date. Russell went above and beyond to get it shipped to Ireland without any fuss to us. Assembly instructions were clear and it took about an hour to assemble, with the main difficutly being caused by a slightly uneven floor. The sauna looks superb and has been working almost ever day for the last 6 months without any issues whatsoever. Highly recommended

Very pleased with the purchase of our Sun Stream infrared sauna. It is a well constructed quality product. The Evolve 10 model fits perfectly in the small space that we had available. Assembly is straightforward as per included instructions and online video. Although some of the wall panels are quite heavy, my husband and I put it together with no great difficulty. The whole process of unpacking, carrying the panels to an upstairs room and assembly took just over one hour. We are delighted with our purchase and now enjoying the benefits of the infrared sauna.

Great service . Even had a reply from my email on a bank holiday. Extremely helpful. Had to wait 6 weeks for delivery as it was out of stock but kept up to date on delivery. The sauna is amazing . It heats up very quickly and I actually sweat which I have found very difficult in traditional saunas. Fitting was straightforward with very comprehensive instructions. Just be aware when carrying in the side panels that the glass decorative strips are not held in place once the packaging is removed and one of ours fell out and smashed. The company offered to replace it but it was on the side next to the wall so it can’t be seen anyway. I did a lot of research before buying this and I couldn’t be happier with my sauna. Been in nearly every night , love it !
