SaunaLife CL3G - Compact 2-Person Outdoor Cube Sauna

The SaunaLife CL3G is the most compact cube sauna in the SaunaLife lineup, delivering a modern Scandinavian sauna experience in the smallest footprint possible. Perfect for urban backyards, patios, rooftop decks, or poolside installations where space is limited, the CL3G comfortably seats two bathers inside a beautifully designed thermo-spruce enclosure with a full glass front wall. Despite its compact dimensions, the interior offers over 6 feet of headroom and thoughtfully contoured benches for genuine all-session comfort.

The cube design delivers a distinctly different aesthetic from traditional barrel saunas. Clean architectural lines complement modern homes, contemporary landscapes, and minimalist outdoor living spaces. The full glass front connects you to your surroundings and makes even the smallest spaces feel open and airy. Handcrafted in Northern Europe, the CL3G is engineered for simple two-person DIY assembly and year-round outdoor durability in all climates.

Frequently Asked Questions

Do I need a permit to install it?

Permit rules vary by municipality. Many areas treat freestanding saunas like sheds, which are often exempt below a certain footprint. Electrical work typically requires a licensed electrician. We supply spec sheets that make the permit conversation straightforward.

I love the Sauna and cold plunge I purchased from Sweat Decks. In addition to providing great products, their office is extremely helpful. My backyard is now a delightful retreat.

We had a great experience overall working with this team. They built and installed our sauna and also constructed a staircase leading up to it, and the final result exceeded expectations. I’ll note that things were a little bumpy right after purchase — the original person we worked with ended up leaving without notice, which caused some initial confusion. That said, the team handled it really well. Huge shoutout to Heath and Brandon for stepping in, taking ownership, and getting everything back on track. They were incredibly professional, thorough, and easy to work with throughout the rest of the process. From there, everything ran smoothly. The craftsmanship is excellent — the sauna looks beautiful, feels high quality, and the staircase ties everything together perfectly. You can tell a lot of care went into both the design and execution. They showed up when they said they would, communicated clearly, and kept everything clean and organized during the build. In the end, they absolutely delivered. Really happy with how everything turned out and would definitely recommend them.

I got a sauna and a plunge in the backyard from Sweatdecks. It was a one stop shop. After delivery, build, and execution they continue to be responsive for questions, and recommendations. Top shelf company. 5 stars! Many thanks, Heath.

Sweat Decks was incredible to work with! They built out my hot tub, sauna, and cold plunge and everything turned out amazing. The whole process was smooth, the team was professional, and they went above and beyond to make sure everything was perfect. What impressed me most is that the service didn’t stop once the build was done — they’ve been super responsive and helpful with any follow-up. Couldn’t recommend them more! ⭐⭐⭐⭐⭐

We went with Sweat Decks for our sauna installation and couldn’t be happier with the decision. They started with a site visit to figure out the best placement. We prioritized views and access to power and water and fortunately the best spot was also the least expensive for the build. There was a rough work visit from the electrician a few days before install, where he met with the courier to secure delivery of the sauna and heater. Then the guys came out and installed it in one day that weekend. For the longest, I had in my mind this idea that I could just DIY this project (and I could!), but why do that when you’ve got some experts who can get the job done right the first time! After getting the sauna my sleep stats are improved and my resting heart rate is down significantly. As parents, I believe this was one of the best investments we could’ve made! If you’re looking at Sweat Decks for the work, my guess is you’re already sold on their quality based on the reviews, but you’re not sure about the cost. That’s where we were for a while before just pulling the trigger. My only regret is waiting so long to get this sauna!

We love our sauna and cold plunge! We have used them without fail everyday since they have been installed. Working with Brandon has been super easy, he is very responsive and happy to answer any questions along the way.\ I’ve owned other saunas and a different cold plunge that required manual chilling. The difference is undeniable. The sweat decks products are superior and 100 times easier to use on a daily basis. The whole family loves them both.
