Barrel Sauna Buying Guide: 7 Things to Check Before You Buy

7 things to check before you buy a barrel sauna

A barrel sauna is one of the best ways to get a real sauna in your backyard. The round shape heats up fast, sheds rain and snow, and looks great on a deck or patio. But barrel saunas are not all built the same. Here’s what to look at before you buy, from the wood and the floor to the roof, the heater and how it gets to your yard.

1. The wood

Most barrel saunas are made from one of three woods:

  • Western Red Cedar. The classic. It smells great, resists rot and insects naturally, and stays comfortable to touch when it’s hot. Grade matters: look for clear or knotty grades that are dried and sorted, not just “cedar.”
  • Thermo-Spruce or Thermo-Pine. Wood that’s been heat-treated so it holds up to moisture and weather. SaunaLife builds its Ergo barrels from Thermo-Spruce.
  • Pacific cedar and hemlock. Common in barrel sauna kits from larger brands.

2. Stave thickness and the bands

The staves are the long boards that make up the barrel. Thicker staves hold heat better and stay tighter over the years. Setri’s barrels use 1.2″ Western Red Cedar staves. The bands that hold the barrel together should be stainless steel and adjustable, because wood swells and shrinks with the seasons and you’ll want to snug them up.

3. The floor

Many barrel saunas have a curved floor that follows the barrel. It works, but it’s awkward to stand on. A flat floor is easier and safer to walk on. Setri barrels have flat cedar floors with removable sections and screened drains, so cleaning is simple.

4. The roof

A bare barrel will shed water, but a roof makes it last longer. Shingles are the standard. A metal roof sheds snow and rain fast. Look at how the roof edges are finished: winged edges carry water off past the staves instead of letting it run down the sides.

5. Size: how many people, really?

Barrel sizes are usually listed as diameter by length, like 6′ x 6′. As a rough guide from our lineup:

SizeSeatsGood for
6′ x 4′2Couples, small yards
6′ x 6′4Most families
6′ x 8′ or 7′ x 6′6Bigger families, friends over
7′ x 8′8Groups, rentals
6′ x 12′ or 7′ x 12′6 to 8, plus a changing roomYear-round use in cold climates

A front porch or changing room adds space to sit, cool off and change, which is a big deal in winter.

6. The heater

Electric, Wi-Fi electric, wood or gas: the right choice depends on power at your site and how you want to use the sauna. We wrote a whole guide on it: how to choose a sauna heater.

7. Kit or fully assembled?

A kit ships flat and you build it, which saves on shipping and works well if you’re handy. A fully assembled barrel shows up ready to heat. You need clear access to your spot, but there’s nothing to build.

  7. Decide on kit or fully assembled, and check delivery access.

Barrel sauna questions

How long does a barrel sauna last?

A well-built cedar barrel sauna with a roof, a good base and a little seasonal care can last many years. Keeping it off the ground, tightening the bands and treating the outside help the most.

What do I put a barrel sauna on?

A level base: a concrete pad, pavers, compacted gravel or a sturdy deck. It needs to be level and drain well.

Do barrel saunas work in winter?

Yes. The round shape heats quickly, and a roof, a porch or a changing room makes winter use even better. We’re in Minnesota, so ours get used all winter.

Can a barrel sauna be delivered fully assembled?

Yes. Our Setri barrel saunas are delivered fully assembled anywhere in the USA. Call us for lead time.
