Barrel saunas for sale

A barrel sauna is the fastest outdoor sauna to heat and the easiest to place. The round shape has less air to warm, and rain and snow run straight off.

What to check before you buy

Length decides capacity

Almost every barrel is about 6 feet across. Length sets how many people fit: 4 to 5 feet for two, 6 feet for four, 7 to 8 feet for six.

Electric or wood heat

Most electric sauna heaters from 4.5 to 9 kW need a dedicated 240V circuit wired by a licensed electrician. Budget for that work on top of the sauna price. A wood burning stove needs no power and suits a cabin or off-grid lot.

Cedar or thermowood

Western red cedar is light, rot resistant and aromatic. Thermally treated spruce or pine costs less and moves less with moisture. Both last outdoors with basic care.

Barrel or cabin sauna?

Pick a barrel if you want quick heat, a small footprint and the lowest price per seat. The curved walls mean the top bench has less shoulder room, and there is no flat wall for a tall person to lean on.

Pick a cabin or cube sauna if you want full headroom, upper and lower benches, or a porch and changing room.

An outdoor sauna needs a flat, level base that drains: a compacted gravel pad, concrete pavers, a concrete slab or a solid deck all work. Most barrels ship as a pre-cut kit on a pallet and two people can build one in a day.

Common questions

How much does a barrel sauna cost?

Most barrel saunas from US dealers sell for about $5,000 to $10,000, depending on length, wood and heater. Panoramic glass, a porch or a larger heater add to the price.

How long does a barrel sauna last?

A cedar or thermowood barrel that sits on a draining base and gets its bands checked once a year can last 15 to 20 years or more.

Does a barrel sauna need a roof?

No. The staves shed water on their own. Many owners add a shingle or metal cover over the top half to protect the wood from sun and standing snow.
