Shoppers comparing outdoor sauna woods often ask about Sugi cedar vs Western Red Cedar: which belongs on a backyard cabin that will see sun, snow, heat, and humidity for years? Both are real cedars with a long outdoor reputation, but they are not identical species. This guide covers practical differences for traditional outdoor saunas, why Blazin Saunas builds with Sugi cedar, and how to choose without marketing noise.
We handcraft outdoor saunas in East Idaho. Free shipping to the contiguous U.S. (Hawaii and Alaska shipping is quoted) on our pods, barrels, cubes, and Timberline. Teton and Blackwood arrive fully built and ship on a quoted rate based on your location and whether a crane is needed. Start with our Outdoor Sauna Buying Guide. Wood context: Sugi cedar outdoor saunas.
Quick answer
- Western Red Cedar (WRC): A well-known North American cedar used in decks, siding, and many sauna kits. Soft, aromatic, and naturally weather-tolerant when properly detailed.
- Sugi cedar: Japanese cedar (Cryptomeria japonica), valued for outdoor durability, classic cedar aroma in the hot room, and stable performance in outdoor cabins. This is the wood Blazin uses.
- Blazin’s choice: Sugi for outdoor builds (thickness, weathering, aroma, and day-to-day cabin performance), not a claim that WRC is “bad wood.”

What outdoor sauna wood has to do
An outdoor sauna is not indoor furniture. The shell cycles through UV, rain or snowmelt, freeze–thaw, and high interior heat with humidity when you ladle water onto stones. Species, thickness, roof detailing, and care all have to match the climate.
What matters in practice: moisture behavior as wood wets and dries; heat and aroma in the hot room; dimensional stability in thick wall stock; and build grade. Wall thickness and joinery beat thin import skins regardless of the cedar name on the brochure.
Pods, barrels, cubes, and Timberline have 1 5/8" thick Sugi cedar walls. Teton and Blackwood are insulated cabins; inside, you can choose Sugi cedar, Thermo Spruce, or Thermo Aspen, and exterior siding is chosen per build (Teton vs Blackwood). Species and thickness work together; neither replaces the other. How we join it: clean build, no glue.
Western Red Cedar: strengths and honest limits
Western Red Cedar earned its reputation for a reason. It is lightweight for its class, naturally aromatic, and commonly specified for outdoor architectural wood. Many sauna builders use WRC successfully when design, roof, and maintenance match the site.
Honest caveats (not attacks): grade and grain matter; “cedar” on a product page can mean different species; and outdoor performance still depends on roof, drainage, pad, and seasonal care. Wood alone does not forgive a wet base or a missing metal roof package.
If you already own a well-built WRC cabin that is performing, keep caring for it. This page is about choosing wood for a new Blazin build, not rewriting every cedar project on the market.
Sugi cedar: why we use it outdoors
Sugi (Japanese cedar) is a traditional outdoor and construction wood in its home range. For Blazin’s East Idaho builds, we chose Sugi because it fits how we design backyard saunas: thick wall stock, black-metal outdoor roof packages on many models, and traditional electric, wood-burning, or gas and propane heat, not infrared.
What we care about in the field:
- Outdoor durability: A species with a track record for exterior exposure when milled and detailed correctly
- Aroma in the hot room: That recognizable cedar character when the cabin reaches temperature
- Outdoor performance with thick walls: Pairing Sugi with 1 5/8" walls on pods, barrels, cubes, and Timberline (Teton and Blackwood are insulated cabins) and proper outdoor packages so the cabin climbs to heat and ages as a backyard structure
We do not invent lab percentages or “X times more durable” claims. Performance is species + grade + thickness + roof + site + care. Our job is to pick a cedar we trust for that stack and build it carefully in East Idaho.

Side-by-side for buyers
| Topic | Western Red Cedar | Sugi cedar (Blazin) |
|---|---|---|
| Common reputation | Popular North American outdoor / sauna cedar | Japanese cedar chosen for our outdoor cabins |
| Aroma | Classic cedar scent when hot | Classic cedar aroma in traditional heat sessions |
| Outdoor use | Widely used outdoors when graded and detailed well | Selected for durability and outdoor shell performance on our builds |
| On a Blazin cabin | Not the species we mill for production | Sugi; handmade East Idaho |
| What still matters either way | Wall thickness, roof, pad, heater sizing, and maintenance | |
If a competitor lists WRC, ask about wall thickness, roof package, grading, and maintenance: the same questions you would ask us. Species name alone is not a complete outdoor sauna spec.
Heat, smell, and daily use
Traditional outdoor saunas aim for a hot-room experience with stones and löyly, typically about 175–230°F (as listed for our pods, Pod Mini, cubes, 2 Person Barrel, XL Barrel, and Timberline) once the heater is sized correctly, under normal conditions. Cedar’s job is structural and sensory: hold the shell and contribute that familiar scent when the air is hot.
Both WRC and Sugi can deliver a cedar-forward smell. We standardized on Sugi so our Outdoor Saunas collection shares one outdoor wood story: consistent sourcing, build practice, and care advice.

Maintenance for any cedar
Whatever species you choose, outdoor cedar ages. UV softens color; wet bases and trapped leaves speed wear. Wipe benches after sweaty sessions when practical, crack the door briefly after use, keep roof and base clear, and keep the pad level. We don’t prescribe a single stain brand. Ask us for finish ideas matched to your climate.

How to decide
- Buying a Blazin outdoor sauna: You’re choosing Sugi by design. Focus next on shape, capacity, heater, pad, and electrical.
- Comparing brands that advertise WRC: Fair. Compare wall thickness, roof, warranty language, assembly support, and shipping, not just the cedar label. Our handmade vs imported checklist lists 10 questions to ask any seller.
- Already set on WRC elsewhere: Respectable when the builder grades and details it well. We’re simply clear that Blazin production is Sugi.

Frequently asked questions
Is Sugi a real cedar?
Sugi is Japanese cedar (Cryptomeria japonica). It is a different species from Western Red Cedar, and it is the wood Blazin uses for its outdoor saunas.
Does Blazin use Western Red Cedar?
No. Blazin production is Sugi cedar. Pods, barrels, cubes, and the Timberline have 1 5/8" Sugi cedar walls, joined without glue and fastened with stainless steel screws.
What wood is inside the Teton and Blackwood?
The Teton and Blackwood are insulated cabins. Inside, you can choose Sugi cedar, Thermo Spruce, or Thermo Aspen, and the exterior siding is chosen per build.
Is Sugi or Western Red Cedar better for an outdoor sauna?
Both can work outdoors when graded and detailed well. Wall thickness, roof, base, heater sizing, and care matter as much as the species name. We chose Sugi for our outdoor builds and do not claim lab numbers for it.
How do I care for a Sugi cedar sauna?
Wipe benches after sweaty sessions when practical, crack the door briefly after use, keep the roof and base clear, and keep the pad level. See our cedar sauna maintenance guide for seasonal steps.
What should I ask a seller who lists cedar?
Ask which species, the wall thickness, the roof package, the warranty, assembly support, and shipping terms. A species name alone is not a complete outdoor sauna spec.
