to a friend
We are very happy with our Cube. The team helped us decide which configuration would be best for our needs and they were spot on. They were extremely helpful throughout the entire process from purchase through the DIY kit build. Shout out to the rep who was on top of every question we sent over — she went above and beyond, even walking us through care and maintenance of the cedar. The curbside freight delivery was painless and the half-glass front looks stunning in our yard.
If you're looking for a quality traditional sauna I highly recommend this Cube. We wanted something clean and traditional without chemicals, and the Cube was exactly it. We don't have a large backyard so fit mattered — it sits beautifully and still seats my husband and me comfortably. Assembly of the kit took a few days and, aside from a couple of fuzzy spots in the instructions, went smoothly. The wood smells amazing and the build quality is high. Our HUUM 7.5kW heater takes it from 60 to about 175°F in 15-20 minutes. I'm actually excited for my 5am workouts now knowing the sauna is waiting after.
We love our new Cube. The LTL freight driver was great and even helped me move the pallet up to my carport so it wasn't on the street overnight. The construction feels solid and it smells delightful — buy the maintenance kit so you can oil and wax before first use. We got the Harvia heater and it's solid, though in colder California nights I'd want a little more power since the front is mostly glass and heat escapes fast when you open the door (it does heat back up quickly). My only real gripe is the instructions could be clearer, but our installer figured it out. Satisfied customers so far!
The best service you can ever imagine. My electrician wasn't the best, and the support team was patient, explained every step in detail, and even sent replacement parts to make sure everything was wired and working properly. The sauna itself heats evenly and the cedar interior is gorgeous. Highly recommend buying here.
Just got the CL4G Cube and couldn't be happier. Customer service was supreme — very knowledgeable, and the freight arrived pretty quickly. After getting the kit assembled it feels solid and built to last. It heats up really well and I finally get to relax in my own sauna in peace, or with my wife after a long day. An amazing sauna and an amazing buying experience.
Elegant looking sauna and a great addition to our backyard and lifestyle. The kit went together over a weekend, the glass door is beautiful, and the benches are wide enough to lie down on. Thanks to the team for their support and communication from order through delivery.
We absolutely love the quality of our sauna. The directions need some improvement — not as clear as they should be — so you have to get creative, but overall the build went fairly smooth. Quality has been excellent: it looks very attractive from the outside and the cedar bench wood is top notch. We've used it a handful of times with no issues. Easy to communicate with before arrival and the freight came quickly. Only complaint is the confusing instructions.
We bought the CL4G ahead of winter and it has become our nightly ritual. From 50°F it climbs to around 180°F in under 25 minutes with the upgraded heater, and the cabin holds heat well even on snowy nights. The clear cedar smells incredible and the half-glass door makes it feel open rather than boxed in. Two of us fit easily for recovery after skiing.
SaunaLife Cube CL4G — great kit, panels were well packaged on the pallet and everything was labeled. Heats fast and feels premium.
Who the SaunaLife CL4G Is Built For
The SaunaLife CL4G is a 3–4 person outdoor cube sauna built for backyards, patios, and garden settings. Its compact Thermo-Spruce cabin suits couples and small families who want an authentic Finnish sauna at home without a large footprint. Because it ships as a pre-cut DIY kit, it is a practical choice for homeowners comfortable assembling with basic tools and a 2–3 person team, and the weather-treated exterior is made for year-round outdoor use.
DIY, On-Site
CL4G Assembly & Site Preparation
The SaunaLife CL4G ships as a pre-cut DIY kit you assemble on-site in about 4–8 hours. Here's what to expect, step by step.
Site Preparation
Choose a level, well-drained location and clear 2–3 feet around all sides for airflow and access before assembly.
Frame Assembly
Assemble the pre-cut wood frame using the included manual and hardware, checking that everything is square and level as you progress.
Panels & Insulation
Add the interior insulation, attach the wall and roof panels, and seal gaps with the provided weatherstripping.
Heater & Electrical Hookup
Mount the electric heater on an interior wall and run the power cable; hardwired hookup may require a licensed electrician per local codes.
Thermo-Spruce & the Cube Sauna Design
The CL4G is built from Thermo-Spruce — spruce heat-treated to improve dimensional stability, moisture resistance, and durability, making it well suited to an outdoor sauna exposed to the elements. Its cube-style cabin maximizes interior bench space in a compact outdoor footprint, seating 3–4 across upper and lower benches, while the modern silhouette fits contemporary backyards and still delivers traditional Finnish steam heat.
More About the SaunaLife CL4G
Can the CL4G be used outdoors year-round?
Yes. The CL4G is an outdoor sauna with a weather-treated Thermo-Spruce exterior designed for year-round use on a level, well-drained site.
Does the CL4G come with a heater?
The heater is selected separately so you can match the output to your needs, or you can buy the CL4G as a complete bundle with a compatible electric heater.
What tools are needed to assemble it?
Basic hand tools — a wrench, screwdriver, and level. All wood is pre-cut and pre-drilled, so no cutting or fabrication is required.
How is the sauna maintained?
Keep the interior wood clean and dry between uses, treat the exterior as recommended, and keep proper ventilation and drainage around the cabin.
