When choosing an outdoor sauna, the first question is usually shape: barrel, cube, cabin or semi-circular? The short answer: a barrel sauna is compact, heats up fast and looks classic; a cube sauna gives you more headroom and a modern look; a cabin sauna brings the view inside through a panoramic glass front; and a semi-circular or elliptical sauna combines the barrel’s curves with more space. Barrel and cube saunas seat 2–6 people; cabin and semi-circular saunas seat 4–8.
Below we compare the main types by shape, heat, interior space, appearance, capacity and price.
Sauna types compared
| Model | Shape | Capacity | Approx. price | Strength | Keep in mind |
|---|---|---|---|---|---|
| Barrel sauna | Cylinder | 2–6 people | 6,000–12,000 AZN | Fast heat-up, classic look, compact | Ceiling is lower along the sides |
| Cube sauna | Cube, straight walls | 2–6 people | 6,000–12,000 AZN | Headroom, modern design, easy layout | Slightly more volume — size the heater correctly |
| Cabin sauna | Rectangular, panoramic glass facade | 4–8 people | 8,000–15,000 AZN | The view, spacious interior | Glass means a slightly more powerful heater |
| Semi-circular / elliptical | Oval, soft arch | 4–8 people | 8,000–15,000 AZN | Barrel looks + more room | Needs a little more ground than a barrel or cube |
Prices are approximate and depend on size, interior wood, heater and extras.
Barrel sauna: the classic that heats fast
Shape and heat
The barrel’s round cross-section helps hot air circulate smoothly along the curved ceiling. Compared with a rectangular room of the same length, there’s less air to heat, so a barrel sauna usually warms up quickly and uses the heater efficiently.
Interior space
The highest point is in the middle, and the ceiling drops towards the sides. Benches typically face each other — a cosy, sociable layout for a family or a group of friends.
Construction
Our barrel saunas come with adjustable metal bands: when the wood naturally shrinks with weather changes, the body can be re-tightened. More on our barrel sauna page.
Best for: people who want a classic look, a compact footprint and fast heat-up.
Cube sauna: modern design and usable space
Shape and heat
A cube sauna has straight walls and a flat ceiling, which means more headroom — especially welcome if you’re tall. Hot air collects under the ceiling, so the upper benches are the hottest zone; with a properly sized heater and good ventilation, heat spreads evenly.
Interior space
A rectangular plan lets you fit L-shaped or multi-tier benches and use every centimetre well.
Appearance
The cube suits modern architecture, minimalist gardens and villas. The cube sauna we built in Gakh/Ilisu (Qax/İlisu) is a good example.
Best for: people who prioritise modern design, more interior space and a higher ceiling. See models on our cube sauna page.
Cabin sauna: the view from the bench
A cabin sauna is rectangular, and its defining feature is a panoramic glass facade. It’s ideal for plots with a mountain, forest, lake or sea view — you sit in the heat and look out at nature.
- Capacity: 4–8 people — roomy for family and guests.
- Heat: glass loses more heat than timber, so the heater is sized with the glass area in mind.
- Example: our cabin sauna at Sea Breeze.
Best for: owners of scenic plots, hotels and resorts.
Semi-circular and elliptical (oval) sauna
This model keeps the soft, arched shape of a barrel but offers more width and height. You get the barrel aesthetic with room for more people.
- Capacity: 4–8 people.
- Advantage: more comfortable seating and movement than a barrel.
- Best for: people who love the barrel look but need a sauna for a bigger family or group.
Bigger plans: cottage sauna and outdoor spa complex
If a single sauna room isn’t enough:
- Cottage sauna — house-shaped; can combine a sauna room, steam room, salt room, Turkish hammam, massage room, hot/cold tub or pool, bathroom and a relaxation room. 4–20 people, 10,000–50,000 AZN.
- Outdoor spa complex — a “5-star-hotel-level private spa in your yard”. 4–15 people, 15,000–45,000 AZN.
See every model on our outdoor saunas page.
What every model has in common
Whatever the shape, our outdoor saunas are built to the same standard:
- Exterior cladding: water-resistant, thermo-treated larch (“listvenica”, also called ship timber).
- Interior lining: linden by default; cedar, abachi, African abachi or teak on request.
- Walls: multilayer build with mineral stone wool and a special moisture-blocking membrane.
- Roof: tegola shingles over roofing felt; ondulin or profiled metal sheet on some models.
- Heater: Harvia, SAWO, Teplodar, TMF or Fanlan — wood-burning or electric.
Before you choose: site and installation
Choose the shape with your plot in mind, not just your taste:
- Space and footprint. A barrel or cube fits even a small garden; cabin, semi-circular and cottage saunas need more ground.
- Base. The sauna should sit on a level, solid surface with no water pooling underneath.
- View and orientation. Point a cabin sauna’s glass front at your best view — while keeping privacy from neighbours in mind.
- Power or chimney. Plan a suitable circuit for an electric heater, or a chimney outlet and wood storage for a wood-burning stove.
- Path and access. Make the route from the house comfortable and safe in winter too, and leave room for a cold plunge or shower.
Which sauna is right for you?
- You want a compact 2–4 person sauna that heats fast → barrel sauna.
- Modern design and a high ceiling matter to you → cube sauna.
- You have a great view → cabin sauna.
- You love the barrel shape but need more room → semi-circular or elliptical sauna.
- You want a sauna, hammam, plunge tub and lounge under one roof → cottage sauna or outdoor spa complex.
FAQ
Barrel vs cube sauna — which is better?
A barrel is more compact, looks classic and usually heats up faster. A cube offers more headroom, straight walls and a modern look. Capacity and price ranges are the same: 2–6 people, 6,000–12,000 AZN.
How much does a cube sauna cost?
The approximate price range for a cube sauna is 6,000–12,000 AZN. The exact cost depends on size, interior wood, heater and decor.
Doesn’t a cabin sauna get cold in winter because of the glass?
Glass loses more heat than wood, but that’s offset by choosing the right heater output. The walls are protected by multilayer insulation, so a cabin sauna is comfortable in winter too.
What size sauna should I choose?
Count how many people will use it at the same time and add one or two seats of margin. For a family, a 2–6 person barrel or cube works well; for hosting guests, look at a 4–8 person cabin or semi-circular sauna.
Can I choose the interior wood?
Yes. Linden is standard, and you can choose cedar, abachi, African abachi or teak instead.
