A barrel sauna is an outdoor sauna shaped like a horizontal cask: curved wooden staves held together by steel bands, with a flat front wall and door. People like them for the look, the compact footprint and the traditional heat and steam from an electric or wood stove. This guide covers what to check before you buy: size, wood, heater, cost and site preparation.
How a Barrel Sauna Works
A barrel sauna is a traditional sauna: a heater warms sauna stones and the air, and you can pour water on the stones for steam (see what löyly is and wet vs dry sauna). The round shape means less air to heat than in a box of the same capacity. The trade-off is lower headroom toward the sides. Browse our barrel saunas or the wider outdoor saunas range to compare.
Choosing a Size
Barrel saunas in our catalog are listed for 2, 3, 4, 5, 6 and 8 people. The capacity is in each product name, for example the Golden Designs St. Moritz 2 Person, the Dundalk CTC Luna 3 Person and the Golden Designs Klosters 6 Person. Seating counts assume people sitting close together, so if you like to stretch out, size up one step. Our sauna size guide explains how to decide.
Choosing the Wood
The barrels we list use a few woods, named in the product titles:
White cedar: the Dundalk CTC Harmony, Luna, Serenity and Tranquility models.
Rustic cedar shingle: the Aleko 4 and 6 person outdoor models.
Red cedar: the Aleko 8 person model.
White pine / Finland pine: the Aleko 4 person and 5 person models.
Cedar is the traditional choice outdoors because it is naturally resistant to decay; see our best wood for a sauna comparison. Check each product page for the wood used on the interior as well as the exterior.
Choosing the Heater
The barrel saunas in this range use electric sauna heaters with stones. Where the product title states it, the heater is 4.5 kW (Aleko 4 and 5 person), 6 kW (Dundalk CTC and Aleko 6 person) or 9 kW (Aleko 8 person). These need a dedicated 240V circuit, so plan the electrical work before delivery. If you would like to see heater options on their own, see our electric sauna heaters. For target temperatures, read how hot a sauna should be.
What Barrel Saunas Cost
At today's prices, barrel saunas in our catalog run from about $3,869 to $6,999, using the current sale price where one applies (read 2026-10-27).

Prices change, so confirm on the product page. Budget separately for the foundation and electrician; our home sauna cost guide covers the full picture.
Preparing the Site
Base: a level, well-drained pad such as concrete, compacted gravel with pavers, or a strong deck. The barrel rests on its own support cradles.
Power: a dedicated 240V circuit installed by a licensed electrician.
Clearance and permits: rules vary by town, so ask your local building department before you order.
Access: measure gates and paths; the barrel arrives as a large unit or kit.
Looking After a Barrel Sauna
Wood moves with the weather, so check the steel bands seasonally, keep the interior dry between sessions and follow the manufacturer's advice for the exterior finish. Our how to clean a sauna guide covers the inside.
Is a Barrel Sauna Worth It?
A barrel suits you if you want a traditional hot sauna with steam outdoors, a compact footprint and a distinctive look. It is less suitable if you want an indoor sauna, plan to move it often, or want a plug-in 120V unit. If you want a plunge afterwards, see cold plunge before or after sauna and our cold plunge tubs.
