Barrel Sauna Buying Guide
Shopping for a barrel sauna? Here’s what to look for—and what to avoid.
Not all barrel saunas are created equal. Before you buy, there are crucial factors that will determine whether your sauna lasts for decades or becomes a headache in a few years. We’ve assembled units from other manufacturers and seen firsthand what works—and what doesn’t.
01Thickness of Wood
What to look for:
The thickness of your wood dictates the natural thermal protection and insulating properties of your sauna. Look for 1.5” minimum.
Why it matters:
In colder climates, wood with only 1” thickness will not hold and retain heat to reach and stay at optimal temperatures. Thicker wood also protects against moisture damage in rainy climates.
Nomad Standard: All units use 1.5" TRUE thick staves.
02Type of Wood
What to look for:
There are many options: pine, spruce, aspen, hemlock, alder, and Western Red Cedar. For larger units, Redwood is an excellent choice.
Why quality wood matters:
Cedar and Redwood outlast other natural woods. Western Red Cedar is naturally resistant to decay and insect damage—no chemical treatment required. Its dimensional stability makes it excellent for the heat and moisture cycles of sauna use.
Nomad Standard: 100% Clear Grade Western Red Cedar for 8’, 10’, and 12’ units. Sustainably sourced Redwood for the staves on 16’ and 20’ units.
03The Stove
Wood-fired vs. Electric vs. Propane:
Each has its place. Wood-fired offers the traditional experience. Electric is convenient for permanent installations. Propane provides quick heat-up with easy fuel access.
What to look for:
Check the recommended cubic footage the stove can heat. Choose a stove where your sauna falls in the middle or low end of its range—this ensures the stove isn’t overstressed and reduces heat-up time.
Quality matters:
Steel is expensive. Cheap stoves may have thin walls that won’t hold up to heavy use. Some kit stoves won’t even hit temperatures above 170°F.
Nomad Standard: We use premium stoves from Iki, Homecraft, Torch, and more—always selecting the best option for your specific sauna.
04Glass Thickness
What to look for:
Many builders and kits use acrylic, plastic domes, or 1/4” glass. This is a large portion of your sauna’s surface area—don’t overlook it.
Why it matters:
Thicker glass holds heat much better and is far more durable. Thin glass or plastic alternatives lose heat quickly and can crack or warp over time.
Nomad Standard: All units feature 1/2” tempered glass overlooks.
05Exterior Finish
What to look for:
If using anything other than cedar or thermally modified wood, an exterior finish is essential. Unfinished pine or spruce will gray out and mold quickly outside.
About Yakisugi:
Yakisugi (Shou Sugi Ban) is a traditional Japanese wood-charring technique that protects cedar against mold, insects, and water while adding insulating value. Many companies paint their units black or add texture to imply a Yakisugi finish—but painted applications lack the functional benefits of the authentic process.
Nomad Standard: Every Nomad unit features authentic Yakisugi. We char the wood ourselves, and it won't fade in the sun—it’s not paint.
06Sizing
What to look for:
Look at actual dimensions—not just a company’s “person sizing chart.” Overall length and interior space matter more than marketing claims.
Nomad Sizing:
- 8’ — Seats 4-6 comfortably
- 10’ — Seats 6-8 comfortably
- 12’ — Seats 8-10 comfortably
- 16’ — Seats 12-14 comfortably
- 20’ — Seats 16-18+ comfortably

How much does a custom barrel sauna cost?
Custom barrel sauna pricing varies based on size, platform (backyard, mobile, or floating), exterior finish (natural cedar or Yakisugi), stove type, and options. Every Nomad sauna is built to order with a custom quote. Schedule a free consultation to discuss your configuration and get a personalized quote.
What is the difference between a kit sauna and a custom-built barrel sauna?
Kit saunas arrive as pre-cut pieces that you assemble yourself. They typically use thinner wood (3/4-inch to 1-inch staves), subpar stoves, lower quality wood — especially in the hidden framing where you can’t see it — and many require you to add insulation and vapor barriers. Kit windows are often thin glass or even acrylic plastic. The biggest structural problem with kits is how they’re assembled: screws and nails permanently affix the staves to one another and to the framing underneath, which prevents the wood from expanding and contracting naturally during heat-up and cool-down cycles. Over time, this leads to cracking and splintering. A custom-built Nomad barrel sauna uses 1.5-inch true thick clear grade western red cedar staves, half-inch tempered glass windows, and compression bands — not screws or nails — to hold the barrel together. The bands allow the staves to move freely with temperature changes, eliminating the cracking problem entirely. You receive a finished, professionally installed sauna built by Nomad craftsmen, not a box of parts.
How long does a barrel sauna last?
Everything varies based on application, but our placed backyard units should exceed 25 years with proper care — no question. Every Nomad barrel sauna comes with an industry-leading 5-year warranty, and the barrel itself — the staves, bands, and structure — is built to last well beyond that. Clear grade western red cedar is naturally rot-resistant and handles extreme heat and moisture cycles well, and the Yakisugi finish adds additional weather protection. The components you’ll maintain over time are doors, hinges, and electrical components if you have an electric stove — normal wear items on any structure. Mobile units carry the same build quality, but the trailer requires upkeep like any trailer — tires, axles, bearings, and hydraulic systems — to stay road-ready for 15+ years. How long your sauna ultimately lasts comes down to owner-level maintenance. We train every customer on our Bake & Breathe method at delivery: after each session, ensure the sauna reaches at least 150°F (Bake), then turn the stove off with the door closed and allow residual heat to evaporate any standing moisture (Breathe). Additional maintenance includes band tightening on a regular schedule, seasonal inspections every 3 months, restacking sauna rocks annually, and operating the sauna at least once every 30 days to prevent climate-related deterioration. Full care details are covered in your purchase agreement.
What barrel sauna size should I choose?
Size depends on how you’ll use it. For personal or couple use, our 8-foot or 10-foot models are a great fit and comfortably seat 4-8 people — perfect for family use and entertaining as well. For commercial or event use, the 12', 16', and 20' barrel saunas are popular choices seating 8 to 20+ people. All sizes feature 1.5-inch true thick clear grade western red cedar staves and half-inch tempered glass overlook windows.
Are there downsides to barrel saunas?
The most common concern with barrel saunas is long-term structural integrity — and it’s a valid one if you’re looking at cheaper kits. Kit saunas use screws and nails that permanently fix staves together, preventing the wood from expanding and contracting naturally during heat cycles. Over time, this leads to cracking, splitting, and gaps. Nomad barrel saunas solve this with stainless steel compression bands that self-adjust with the wood’s natural movement — the same principle used in wooden boat building. The other concern people raise is heat retention compared to a traditional square room. The barrel shape actually heats more efficiently because there are no dead corners where hot air stalls, and our 1.5-inch true thick clear grade western red cedar staves provide excellent natural insulation. When built with quality materials and proper construction, a barrel sauna is a 25+ year investment.
