Six sauna models, three formats, two heater types — deciding where to start can feel more complicated than it needs to be. This guide breaks it down by the things that actually determine whether a sauna fits your life: space, setting, household size, and how much involvement you want in running it. By the end, you should know exactly which model in C11’s range is right for you.
The Three Formats, in Plain Terms
Before comparing individual models, it helps to understand the three shapes C11’s sauna range comes in:
- Cube — an outdoor, glass-fronted sauna with a modern, sculptural silhouette. Sits in the garden, doesn’t touch your home’s interior square footage.
- Barrel — the classic outdoor Nordic barrel shape, in thermo-treated timber. Also fully outdoor, with a more traditional look than the Cube.
- Traditional — an indoor, quick-build cabin designed to install inside your home, with a slim wall-mounted heater that saves bench space.
The single biggest decision most buyers face is outdoor vs indoor, and it usually comes down to one question: do you have garden space you’re happy to dedicate to it, or would you rather it live inside?
What to Consider Before Choosing a Model
- Indoor or outdoor? Garden space vs a dedicated room, utility space or converted area indoors.
- How many people will actually use it regularly? Not the maximum on a good day — your realistic, week-to-week number.
- Electric or wood-fired? Convenience and precise control, or the traditional off-grid ritual.
- How much power do you have available? Some heater options need more capacity than others.
- Is this a first sauna or a confirmed habit? If you’re not certain you’ll use it several times a week, starting smaller is the more sensible move — you can always upgrade once the habit is proven.

Best Sauna for a First-Time Buyer
If you’re not yet certain how often you’ll actually use a sauna, the Traditional 160 is the sensible starting point. It’s the smallest, most affordable model in the range, installs indoors without needing garden space, and gives you the real Finnish sauna experience — stove, stones, steam — without committing to a larger outdoor build before you’ve confirmed it’s a habit you’ll keep up. If you outgrow it, the outdoor Cube and Barrel ranges are there to move up to.
Best Sauna for a Tight Indoor Space
The Traditional 160 and Traditional 210 are both designed as quick-build cabins that fit inside an existing room — a utility space, garage conversion, or dedicated wellness room — without the footprint of an outdoor structure. Because the heater is a slim, wall-mounted unit, they don’t eat into bench space the way some floor-standing heaters do.
Best Sauna for a Garden (Outdoor, Compact)
The Cube 160 is the smallest outdoor option, with a glass front that frames the garden while keeping the footprint manageable. It suits smaller gardens or anyone who wants an outdoor sauna without dedicating a large section of the space to it.
Best Sauna for Groups or Larger Households
The Barrel 210 comfortably seats 4–6, making it the largest-capacity model in the range. Its classic barrel shape and half-panoramic window (or solid back panel option) give it a distinctly traditional look, and like the Cube 210, it can be heated electrically or with a wood-burning stove.
Best Sauna for Flexible Heating (Electric or Wood-Fired)
Both the Cube 210 and Barrel 210 can be configured with either an electric Harvia Cilindro heater or a wood-burning Harvia Linear 18 — useful if you’re not yet sure which you’d prefer, or if your garden doesn’t have a power supply nearby and wood-fired is the more practical route.
Electric vs Wood-Fired: A Quick Recap
- Electric: ready to bathe in 30–45 minutes, precise digital temperature control, optional WiFi scheduling, no fuel or flue to manage.
- Wood-fired: the traditional ritual — the crackle and aroma of a real fire — with no power supply required, ideal for off-grid gardens.
Both reach full bathing temperature. Neither is objectively better; it’s a genuine preference between convenience and authenticity.
Best Sauna for Commercial or Multi-User Settings
For gyms, clinics or wellness studios expecting regular use by multiple people per day, the Barrel 210 or Cube 210 offer the best combination of capacity and durability for daily throughput. Indoor Traditional models also work well for studios with dedicated indoor space and want a quick, low-footprint installation.
Frequently Asked Questions
Which sauna is best for a first-time buyer?
The Traditional 160 is the natural starting point — it’s the smallest and most affordable model, installs indoors, and lets you confirm the habit before committing to a larger outdoor build.
What’s the difference between the Cube and Barrel ranges?
Both are outdoor saunas built from thermo-treated timber. The Cube has a modern, glass-fronted, sculptural design, while the Barrel uses the classic Nordic barrel silhouette. Capacity and heater options are similar across comparable sizes.
Can I have a wood-fired sauna instead of electric?
Yes. The Cube 210 and Barrel 210 can both be configured with either an electric Harvia Cilindro heater or a wood-burning Harvia Linear 18, depending on your preference and whether you have power available in your garden.
How much space do I need for an outdoor sauna?
It depends on the model. The Cube 160 has the smallest outdoor footprint at 225×165cm, while the Barrel 210 needs roughly 215×205cm. All outdoor models need a firm, level surface — the included foundation beams handle the rest.
What’s the best sauna for a larger household or group?
The Barrel 210 has the highest capacity in the range at 4–6 people, making it the best fit for larger households or frequent group use.
Do indoor saunas need special installation?
The Traditional range is designed as a quick-build cabin, typically assembling in a few hours, with a slim wall-mounted heater. It’s more straightforward than an outdoor build, though the right electrical supply still needs to be confirmed beforehand.
