Barrel vs. cabin outdoor saunas: prices, sizes and trade-offs

Last updated Oct 17, 2026. Figures come from our nightly price checks, as of the date shown in each section.

If you’re putting a sauna in the backyard, you’ll mostly be choosing between a barrel (a round tube of staves held together with bands), a cabin (a small rectangular building), and, more and more, a cube (a modern, square, often thermally modified shell). This guide compares them on price, size and practical details, using the outdoor saunas we tracked across 20 stores on October 17, 2026.

Price at a glance (outdoor models only)

“Outdoor” means the store says the model is meant for outdoor use. Prices are the lowest price we found for each model across the stores that sell it.

Barrels are the cheapest of the three and the most tightly grouped. Cabins cover a much wider range: they include everything from simple kits to large buildings with porches and changing rooms.

Size for size

Comparing by stated capacity narrows the gap:

Two things stand out. First, a 6-person barrel costs barely more than a 4-person barrel at the median, because barrels are often sold in a few lengths that share the same diameter and parts. Second, outdoor cabins cost more at every size we could compare, but the samples are small, and cabins vary much more in what’s included.

Capacity numbers are the store’s own claim. A “6-person” sauna in a brochure is often comfortable for fewer people in practice, so check the bench length and interior dimensions when they’re listed.

What you’re paying for in a barrel

• Simple shape, fewer parts. Staves, bands, two end walls, a door and benches. That’s a big part of why barrels cost less.
• Small interior volume for the bench space, which means a smaller heater can do the job. Among outdoor barrels stating heater power, 6 kW is the most common rating (12 models), followed by 8 kW (8 models).
• Wood: among outdoor barrels that state the wood, white cedar is the most common (9 models), then hemlock (5).
• Assembly: usually sold as a kit, and many owners assemble it themselves. Check whether the store sells assembly as an option.

Trade-offs to know about:

• Curved walls limit headroom near the sides and make it awkward to add upper and lower benches.
• Staves move with temperature and humidity. Bands may need adjusting from time to time, especially in the first year. Follow the maker’s guidance.
• Roofing: many barrels sell an optional roof covering (shingles, membrane). In wet or snowy climates, factor that into the price.

What you’re paying for in a cabin

• Upright walls and a flat or pitched roof mean more headroom, standard bench layouts, and room for windows.
• Bigger heaters. Among outdoor cabins stating heater power, 8 kW is by far the most common (33 models), then 6 kW (11).
• More options: porches, changing rooms, larger glass fronts and premium woods are common, and they drive the higher prices.
• More variety by brand. In our data, six different brands each have 7 or more outdoor cabin models.

Trade-offs: more material, often a bigger foundation, and higher shipping weight. And because cabins vary so much, two “6-person outdoor cabins” can differ by thousands of dollars for good reasons.

Cubes: the in-between option

Cubes are box-shaped outdoor saunas, often with a large glass front. In our data they sit between barrels and cabins at the median ($7,990). Among outdoor cubes that state the wood, aspen and thermally modified woods appear most often. Expect a more modern look and, usually, fewer included extras than a large cabin.

Price comparison is harder for barrels

Here’s a practical point from our tracking. Of the 33 outdoor barrels, none was matched at more than one store on October 17. For cabins it was 11 of 95, and for cubes 5 of 36. Barrel listings tend to differ by length, wood, heater and roof options, so they rarely line up as exactly the same product across stores.

What that means for you:

• Compare by spec, not model name. Line up diameter, length, wood, heater brand and kW, and what’s included (roof, bench layout, lighting).
• Ask for a full quote with the heater and shipping included.
• Watch the “compare-at” price. For why it doesn’t prove a discount, see how to tell if a sauna sale is real.

Site and installation questions (same for both)

• Foundation: most makers ask for a level, solid base (pavers, a concrete pad, or a deck rated for the weight). Barrels often sit on cradles, which spreads the load differently than a cabin floor does. Follow the maker’s instructions.
• Power: most outdoor saunas with electric heaters need a 240V circuit. Running power to a backyard is often a big part of the total cost (see what a home sauna really costs).
• Wood-burning heaters avoid the electrical work but add a chimney, clearances, and possibly local permit rules.
• Delivery: big saunas usually ship by freight to the curb. Moving the crates to the backyard is up to you unless the store sells that service.
• Local rules: some towns treat a backyard sauna as an accessory structure. Check setbacks and permits before you order.

Which one is right for you?

A barrel makes sense if you want the lowest price for an outdoor traditional sauna, are fine with a classic look, and want a smaller heater. A cabin makes sense if you want headroom, a standard bench layout, windows, a porch or changing room, or a specific premium wood, and are willing to pay for it. A cube suits you if you want a modern look at a price between the two.

Whatever you choose, compare total delivered prices, not list prices. Browse outdoor models with their stated style, capacity and wood on our all saunas page, and use the compare page to line up specific models.

Where these numbers come from
