BARREL SAUNAS - FOR EASY SAUNA INSTALLATION

Outdoor barrel saunas are curved wooden structures popular for UK gardens, offering efficient heat circulation and quick assembly for DIY enthusiasts. They suit UK's weather with water-shedding designs and thermo-wood for durability. The barrel shape rolls hot air evenly, reducing cold spots and energy use compared to cabin saunas; walls are typically 40-48mm thick thermo-wood or spruce. Many include bronze glass doors, L-shaped benches, and options for verandas or changing rooms; heaters (electric 3-9kW or wood-fired) are extra, often £500-£1,500. These need no foundation—just level pavers—and heat in 1-2 hours for 15-20 minute sessions.

​

In general barrel saunas offer a compact, rustic design ideal for outdoor DIY setups, but they come with notable trade-offs in comfort and efficiency. For quick assembly these saunas ship as flat-pack kits with pre-cut wood, making them easy to install without major tools or foundations, often at a lower upfront cost than cabin-style options. The curved shape reduces air volume by up to 23% compared to square saunas, allowing faster warmup (30-45 minutes) and natural convection that circulates heat evenly without cold corners. Their compact footprint suits small yards, and the barrel look adds rustic appeal to gardens.

​

Having said that, the single-layer wood walls lead to rapid heat loss, especially in cold climates like the North of England, requiring more energy or fuel to maintain temperature. Curved walls provide no upper benches, low seating causes "hot head, cold feet," cramped headroom for tall users, and poor back support. Many poorly designed or installed barrel saunas lack proper vents, causing stuffy air; and exposure to elements can lead to leaks, warping, and higher maintenance without added roofing.

 

Good quality barrel sauna ​prices start from £6,000 for self assembly and the running costs are typically less than £2.50 per hour.
