Choosing the right size
Choose the size according to the number of regular users. A short barrel is enough for a couple; longer models add seats, or even a changing area separated by a glass partition, which is welcome in winter.
Heating
The wood-burning stove remains the most authentic choice and needs no connection. The electric stove can be programmed and avoids smoke, but requires a dedicated electrical circuit installed by a qualified electrician. To choose, follow the same logic as for other outdoor saunas.
Timber and care
Thermowood stands up well to damp; spruce needs regular staining; red cedar is the most durable. A roof covering (shingles, membrane) protects the top of the barrel, the most exposed area. Ventilate after each session so the timber can dry.
Prices
The barrel sauna is often the most accessible way into outdoor saunas. The price varies with length, timber, stove and options (glazing, changing area, lighting). Compare delivered and assembled prices, like for like — and, for the UK, check whether import VAT and duties are included.
Frequently asked questions
Why is a sauna barrel-shaped?
The round shape reduces the volume of air to heat and circulates warmth evenly. The hooped staves also form a strong structure that is easy to deliver and assemble.
How many people fit in a barrel sauna?
Depending on its length, a barrel sauna generally seats 2 to 6 people. Longer models sometimes include a changing area or a covered porch at the entrance.
