The customer service was really great. We couldn’t decide between three models and we called and spoke to Pedram who took care of us. He really cared about making us feel good. Thanks and wish you all the best. :)

About This Collection
Explore SaunaLife Cube saunas designed for outdoor home use. The Cube Series combines a modern Scandinavian profile with thermally modified wood, comfortable benching, outdoor weather protection, and a range of footprints for different spaces and household needs.
When choosing a cube sauna, consider more than capacity alone. The overall footprint, interior depth, bench layout, glass configuration, heater requirements, and available installation space can all affect which model is the right fit for your property.
Why Choose an Outdoor Cube Sauna?
A cube-style sauna offers a different layout from a traditional barrel sauna. The taller sidewalls and more rectangular interior make efficient use of the available floor space while creating a modern architectural look for a backyard, patio, or outdoor wellness area.
SaunaLife Cube saunas are built specifically for outdoor use and combine this space-efficient shape with materials and exterior details intended for changing outdoor conditions. For buyers who prefer clean lines and a more contemporary appearance, an outdoor cube sauna can also integrate naturally into modern landscaping and residential outdoor spaces.
Thermo-Spruce Construction for Outdoor Use
SaunaLife uses thermally modified spruce throughout the Cube Series structure. Thermal modification uses heat and steam to change the properties of the wood without relying on chemical preservatives. The process improves dimensional stability and helps the wood resist decay and pests, making Thermo-Spruce well suited to an outdoor sauna environment.
Full-length wood staves create the main structure, while the exterior roof system includes shingles and drip rails to help manage rainwater. These details matter when comparing outdoor sauna designs because the enclosure must handle moisture and changing weather over time.
Designed for a More Open Sauna Interior
The Cube Series is designed to make practical use of its interior dimensions. SaunaLife combines contoured Thermo-Aspen seating with supportive backrests and planned ventilation to create a comfortable bathing space without requiring an oversized exterior footprint.
Glass also plays an important role in the Cube design. Depending on the model, large tempered-glass surfaces bring more natural light into the sauna and create longer sightlines to the surrounding outdoor space. The result is an interior that can feel more open while maintaining the compact form of a backyard sauna.
Choosing the Right SaunaLife Cube for Your Space
The SaunaLife Cube Series includes several sizes and layouts, so the right choice depends on how the sauna will be used and where it will be installed. Start with the available footprint on your property, then consider how many people will regularly use the sauna, how much interior room you prefer, and whether you want a more compact layout or additional space for seating and movement.
For a detailed breakdown of footprint, bench layout, capacity, heater options, and the differences between the main models, see our SaunaLife Cube Series Buying Guide.
SaunaLife Cube Series Design and Finish
Across the Cube Series, SaunaLife combines natural wood with dark exterior details and glass to create a simple, modern appearance. Thermo-Spruce forms the structure, while smooth Thermo-Aspen is used for seating and backrests inside the sauna.
Many Cube models also include an integrated LED lighting system that can be controlled by remote or Wi-Fi app. Details such as lighting, glass, bench design, and exterior finish help create a more complete outdoor space without changing the core purpose of the sauna itself.
Plan the Complete Outdoor Sauna Installation
The sauna structure is only one part of the project. Heater selection, electrical requirements, site preparation, clearances, drainage, access, and local installation requirements should be considered before the sauna is ordered.

SaunaLife Cube Sauna FAQs
What type of foundation does a SaunaLife Cube sauna need?
SaunaLife specifies a stable, level foundation with enough support for the complete sauna. Keeping the base level is important for proper door and window operation and for keeping the structure square during assembly.
The site should also allow water to drain away rather than leaving the wooden structure in constant contact with standing water. A concrete pad, properly prepared patio, or adequately supported deck may be suitable, but the supporting structure must be able to carry the weight of the sauna, heater, stones, and occupants. Structural suitability should be confirmed before installation.
Do SaunaLife CL4G and CL5G outdoor saunas require on-site assembly?
Yes. The SaunaLife CL4G and CL5G are outdoor sauna kits that are assembled on site. The manufacturer installation manuals include the base, walls, glass front, roof system, benches, ventilation components, lighting, and finishing steps.
The manuals call for common construction tools such as a drill, measuring tape, level, circular saw, rubber mallet, ratchet strap, and additional help during assembly. The sauna enclosure can be assembled according to the supplied instructions, while SaunaLife directs buyers to use qualified professionals for electrical work, including heater and lighting installation.
Does SaunaLife Thermo-Spruce still need wood treatment?
Yes. Thermal modification improves the stability and outdoor durability of the spruce, but it does not eliminate maintenance. SaunaLife recommends treating the wooden parts after assembly and applying a suitable wood preservative as part of ongoing maintenance.
The CL4G and CL5G manuals recommend renewing the protective treatment at least once a year, or more often when conditions require it. SaunaLife also advises against unsuitable finishes and cleaning methods such as harsh disinfectants, pressure washing, or excessive running water on the wood.
How should a SaunaLife Cube sauna be cleaned after use?
SaunaLife recommends wiping the benches with a clean, damp cloth rather than washing the wooden surfaces with running water. Use cleaning products intended for sauna wood and allow the interior surfaces to dry completely after cleaning.
The manufacturer also recommends ventilating the sauna after use. Its maintenance guidance calls for running the heater for at least 30 minutes with the vent open after cleaning so moisture can dry from the interior. Avoid pressure washers and excessive water, which can damage the wood structure over time.
Is cracking or movement in the wood normal in an outdoor cube sauna?
Some natural movement can occur. SaunaLife notes that wood is a natural material and may develop minor cracks or slight changes in shape as it is exposed to repeated temperature and humidity changes.
Wood near hot steam may also darken over time, and thermally modified wood has a characteristic smell that usually becomes less noticeable with heating and ventilation. These natural changes should be distinguished from installation problems, persistent water exposure, or structural damage that requires inspection.
How should I prepare a SaunaLife Cube sauna for its first heating?
After assembly, wood treatment, heater installation, and electrical work are complete, check the sauna and heater against their installation instructions before the first heating. New sauna stones should be cleaned and arranged according to the heater manufacturer's directions so the heating elements are not left exposed.
The SaunaLife CL4G and CL5G manuals call for the first heating to be supervised for about two hours at approximately 210°F, with the sauna well ventilated during and after heating. The temperature must still remain within the limits specified by the heater manufacturer.
What maintenance should be checked each year on a SaunaLife Cube sauna?
Annual maintenance should include inspecting and re-treating the wood as needed, cleaning the interior with sauna-appropriate products, and checking the bench and support hardware for loose fasteners caused by repeated heat and moisture changes.
Door and window hinges, locks, and other moving hardware should also be inspected and adjusted when necessary. Heater stones should be checked periodically because stones can crack and settle with use and may need to be rearranged, replaced, or topped up according to the heater manufacturer's instructions.

What Customers Are Saying
As an older adult starting to use my Power Plate Move I first enjoy the increased circulation of my lower extremities! Then comes balance work, stretching and toning! I love the machine so much I bought two!
This device helps to keep me comfortable. I am also using it after my recent surgery to help with healing. I will continue to use it daily since I see the benefits first hand and I love it.
I use my power plate at least once a day. Feel so relaxed after using it and my muscles are getting very toned especially in my arms and legs. Had an imitation vibration plate before and there’s no comparison. Power Plate blows it out of the water. Such a difference and definitely worth the extra money.
Smooth delivery process. We spoke to other companies and the response was vague. What I liked most about our conversation was that Pedram asked me what was my intention and why I wanted to buy a sauna instead of pushing a sale. This was very different. Appreciate the honesty.
I got an email from Pedram and he mentioned how we could add a sauna to our business. At first, I wasn’t much for it but when we set up an audit and reviewed my business, I liked what I saw. It was definitely an investment on our part but the service has been great for our clients. Thanks again for your support and caring.
I needed something for my basement but didn’t know what to buy. I saw this brand before but couldn’t make a decision. I called Pedram and he walked me through it and we even looked at my floor plans for my basement. This was really fun and I am enjoying it. You guys rock!
My body is not the same as it used to be, but I wanted something that would be ok for me and also give me a good workout. I liked how I was recommended to go with STEPR because it is a low impact fitness machine. Looks good in my garage and my son uses it too.
I was honestly on the fence for weeks because it is not a small purchase. I kept looking at different brands and reading reviews. What made the difference was actually getting on the phone and talking through my space and what I wanted out of it. It feels solid, heats up fast, and has become part of my nightly routine. No regrets at all.
I bought this mostly for recovery after workouts but ended up using it way more than I expected. I sit on it while reading and sometimes just lay on it before bed. It is calming in a way I did not expect. Shipping was smooth and everything came well packaged. Very happy with it so far.
I was not sure if I really needed a massage chair or if it was just one of those things that sounds nice but never gets used. I can honestly say this gets used almost every day. I work long hours and my lower back is usually tight by the end of the day. I sit in it for about twenty minutes in the evening and it actually helps me unwind.
