About outdoor saunas

Red cedar barrel sauna on a lakeside deck at dawn

Outdoor saunas are built to stand in a garden, on a deck or at a resort. Barrel saunas use curved staves held by steel bands; cube and cabin designs use flat walls with a roof system and large glass fronts. Heat comes from an electric stove or a wood-burning stove, so they run at traditional sauna temperatures.

Several models in this line can be built to custom sizes, from 1–2 person cubes to 6–10 person cabins with porches. Plan the foundation, drainage, stove clearances and electrical supply with a local installer, and ask us for the drawings of the exact build.

Electric or wood-burning stove

An electric stove is simpler to control and suits homes and resorts with power available; a 6 kW stove, common on barrel models, needs a dedicated 220–240V circuit. A wood-burning stove suits off-grid sites and cold-climate cabins where buyers want a fire, and needs a chimney and safe clearances. See the wood-burning sauna stove guide.

Outdoor infrared sauna options

Most outdoor saunas here are traditional stove saunas, but one barrel uses a far infrared heater, and some infrared cabins, such as the MS-FS38 3-Person Full Spectrum Infrared Sauna, are listed for indoor and outdoor use under a covered area. An exposed outdoor infrared sauna needs a roof and protection for the electrics.

What to plan for a backyard sauna

  • Base: a level, well-drained concrete pad, pavers or timber deck.
  • Weather: red cedar resists decay; roofing, an anti-UV finish and good drainage extend life in wet or snowy climates.
  • Capacity: from 1–2 person cubes to 6 and 8 person outdoor saunas for families and resorts.
  • Power or flue: plan the electrical supply or chimney route before delivery; check loads with the power calculator.
  • Permits: local rules on structures, chimneys and electrical work apply.

For a custom outdoor sauna with porch, window or layout changes, send the space and capacity you need.

FAQ

Do outdoor saunas need a foundation?

Yes. A level, well-drained base such as a concrete pad, pavers or a timber deck is needed. Barrel saunas sit on cradles that spread the load. Ask for the base drawing for your model so your installer can prepare the site before delivery.

Electric or wood-burning stove for an outdoor sauna?

Electric stoves are simpler to control and suit resorts and homes with power available. Wood-burning stoves suit off-grid sites and buyers who want a fire. Local rules on chimneys and electrical work apply to both, so plan the stove with a local installer.

Can outdoor saunas be customized in size?

Several cube and cabin models are offered in custom sizes and layouts, from 1–2 person cubes to 6–10 person cabins, including porch and window options. Send the space and capacity you need, and we reply with drawings of the build.

Is there an outdoor infrared sauna?

Yes. One barrel model uses a far infrared heater, and some indoor infrared cabins are listed for indoor and outdoor use under a covered area. For fully exposed sites, choose a weatherproofed outdoor model or ask for a roof option, and keep the electrical connection protected.

What is the best outdoor sauna for a cold climate?

In cold climates, buyers often choose red cedar for its decay resistance, a design with a roof that sheds snow, and a stove sized for the room and glass area. A wood-burning stove suits off-grid sites. Plan a well-drained base and insulated, protected services.
