If you’re considering adding a sauna to your home, backyard, or wellness space, you may be wondering which type is right for you. Two popular options are thebarrel sauna and thetraditional sauna.
While both provide the relaxing heat and wellness experience saunas are known for, their design, construction, space requirements, and overall experience can be quite different.
Here’s everything you need to know before choosing between a barrel sauna and a traditional sauna.
A barrel sauna is a sauna designed with a distinctiverounded, barrel-shaped structure. Traditionally made from wood such as cedar, hemlock, or other sauna-grade timber, the curved design gives it a unique appearance while also serving a practical purpose. Unlike a traditional sauna, which typically has straight walls and a flat or angled roof, a barrel sauna has a curved interior. This allows heat to circulate efficiently throughout the sauna while minimizing the amount of unused space.
Barrel saunas are especially popular forbackyards, gardens, patios, and outdoor wellness areas because of their compact footprint and natural appearance.
A traditional sauna, sometimes called aFinnish sauna, generally features a rectangular room with straight walls, benches, a sauna heater, and a ceiling.

Traditional saunas can be installed indoors or outdoors and are often built as part of a home, gym, spa, hotel, or wellness facility.
Because they use a conventional rectangular layout, traditional saunas can provide more flexibility when it comes to interior design, multiple seating levels, and larger capacities.
Although both types provide a traditional heated sauna experience, there are several differences worth considering.

|---|---|---|

| Typical Location | Primarily outdoors | Indoors or outdoors |
