A barrel sauna is a round outdoor sauna built from curved wooden staves held together with steel bands. The shape means less air to heat than a square cabin, and the curved roof sheds rain and snow. Unlike the infrared cabins elsewhere on this site, barrel saunas are traditional saunas: an electric or wood-burning stove heats rocks, and you can ladle water on them for steam. Here are five on Amazon now, with the specs each listing gives.
Our quick picks
- Best overall: INFRADELUX Premium 4 Person Cedar Barrel. Cedar, a Harvia 6kW heater and an asphalt shingle roof, 59 x 79 x 73 inches.

The best barrel saunas on Amazon
1. INFRADELUX Premium 4 Person Cedar Barrel: best overall
A cedar barrel for four, 59 x 79 x 73 inches, with a Harvia 6kW electric heater and a waterproof asphalt shingle roof. INFRADELUX says it comes with a starter set of sauna accessories, but sauna stones aren’t included, so order those too. Its warranty covers personal use only.
2. Bathology Eurosauna 8159: best for up to 3
Designed and made in Estonia, the Eurosauna uses extra-thick Nordic spruce: 1.65-inch barrel staves and 1.1-inch end walls. It has alder benches and backrests, a tempered glass door, intake and exhaust vents, and measures 81 x 59 x 84.6 inches assembled. It’s sold in several kits with different heaters; KIT-1 includes a Harvia KIP60B and sauna stones. The listing says the heater must be connected by a licensed electrician.
3. SunSwell 4-6 Person: the biggest
At 85 x 72.8 x 91.7 inches, the SunSwell seats four to six. It has a full glass door and side windows in 8mm tempered glass, a 6kW electric heater with a controller and timer, a waterproof insulated roof cover, and sauna stones, a thermometer and wooden steps in the box. It needs a 220V supply and comes without a power cord, so plan for an electrician.
4. Royal Saunas 4 Person Vertical Barrel: small footprint
A vertical barrel stands on end, so it takes a 63 x 63 inch square of ground and stands 78.7 inches tall. This one is cedar, with an ETL-certified Harvia 6kW heater and 5-color LED lighting on a remote. Sauna stones are sold separately.
5. AURGOD 4 Person Barrel with Porch: wood-burning
If you’d rather not run power to the garden, this AURGOD barrel uses a cast iron wood-burning stove with a chimney kit. It’s red cedar, 71 x 95 x 71 inches outside with a covered front porch, a half glass back window and a three-layer waterproofing system, and AURGOD says the bench is long enough for a 5 foot 6 inch person to lie down. Volcanic rocks, a bucket and a ladle are included. When we checked, Amazon listed it with a lead time rather than ready to ship.
Before you buy a barrel sauna
- A level base: barrel saunas sit on cradles, so they need a flat, solid pad such as concrete, pavers or a deck rated for the weight.
- Power: electric heaters in this size usually need a dedicated 220V to 240V circuit, wired by a licensed electrician. Wood-burning models skip the wiring but need clearance for the chimney.
- Stones: several listings here leave out the sauna stones. Check what’s in the box.
- Weather: a shingle roof or roof cover adds protection over bare staves. Cedar weathers to silver over time unless you treat the outside with a UV-protecting stain; never treat the inside.
- Assembly: expect a day with two people. Check whether the seller offers installation help.
Barrel sauna or cabin?
A barrel heats a little faster because there’s less air inside, and the round shape handles weather well. A square or rectangular cabin gives more headroom and more room to move. If you want an infrared sauna for the garden instead of a traditional one, see our outdoor infrared sauna picks. Traditional saunas run much hotter than infrared ones, so read our guide to using a sauna safely before your first session.
Two small accessories for a barrel sauna
In a traditional sauna the air near the ceiling is much hotter than at bench level, so many people wear a wool hat to keep the heat off their head and hair. Halsa’s is 2 mm wool felt, and its listing says it suits traditional saunas, steam rooms and infrared saunas.
A sand timer on the wall keeps track of each round without bringing a phone into the heat. The YLTIMER runs 15 minutes, with 5 and 10 minute marks, and mounts with the hardware included. Its listing says it’s made for sauna heat and humidity, and that the sand can run about 10% fast or slow.
Frequently asked questions
What is a barrel sauna?
A round outdoor sauna made from curved wooden staves held by steel bands. It’s a traditional sauna: a stove heats rocks, and you can pour water on them for steam.
Do barrel saunas need a 240V circuit?
Electric ones usually do. The SunSwell 4-6 Person lists a 220V supply, and a 6kW heater like the Harvias here normally needs a dedicated circuit fitted by an electrician. A wood-burning barrel needs no electrical hookup.
How big is a 4 person barrel sauna?
The INFRADELUX 4 Person is 59 x 79 x 73 inches, and the AURGOD 4 Person with porch is 71 x 95 x 71 inches, per their listings. Allow extra space around it for access and airflow.
Are sauna stones included with a barrel sauna?
Not always. The INFRADELUX and Royal Saunas listings say stones are sold separately, while the SunSwell, Eurosauna KIT-1 and AURGOD include them.
What wood is best for a barrel sauna?
Cedar and spruce are the most common. Cedar resists rot and has a strong scent; thick Nordic spruce, as in the Eurosauna, is dense and holds heat well. Leave the inside untreated.
