Cedar outdoor saunas
Best cedar outdoor saunas in the UK (2026)
Cedar is the timber the sauna market aspires to: rot-proof by chemistry, treatment-free by nature, and the smell everyone remembers. UK buyers reach it three ways, list-price barrels from £3,995, dealer imports, and British commissions. These are the five worth shortlisting.

The 5 best, ranked
Out of the Valley
9.5out of 10
Cedar is this Devon workshop's native material: commissioned cabins drawn for their site, built by hand in western red cedar with sheep's wool insulation and detailing nearer furniture than garden building. The range runs from the compact Forest to the towable Aquila, with HUUM heaters among the options.
Our verdict
If the search is for the best cedar object money can put in a British garden, this is where it ends. Every build is one-off, the material work rewards standing close, and the waitlist is the proof. The practical caveats are the usual commission ones, months of lead time and per-project pricing, which is why the ready-made cedar below exists.
Ideal for
- One-off builds drawn for the site
- British craft in western red cedar
- Buyers with patient timelines
Not ideal for
- A sauna in the garden this season
- Budgets that need a list price
- Simple installs a kit already serves

Fonteyn Rustic Red Cedar barrels
8.4out of 10
Ready-made western red cedar at list prices: four barrel sizes from £3,995 to £6,295, heater included, 2 year structural warranty. This is the counterpoint to the commission route, cedar you can order today with a delivery date attached.
Our verdict
For most cedar buyers this range answers the actual question, which is how to get real red cedar into the garden without a commission's timeline or mystery pricing. The barrel shape does the weathering work cedar is famous for, the heater is in every price, and the 8ft size seats a family. The compromise is form: it is a barrel or nothing.
Ideal for
- Cedar this season at a published price
- Any size from couple to family of six
- Buyers who want the heater included
Not ideal for
- Cabin layouts with L-shaped benches
- Wood-fired configurations
- One-off design ambitions

Dundalk LeisureCraft
8.6out of 10
Dundalk builds in clear western Canadian red cedar, barrels and cabins both, backed by a 5 year warranty that doubles most of the market's cover. Wood-fired and electric configurations run across 2 to 6 seat models, sold in Britain through specialist dealers.
Our verdict
The 5 year warranty is the stand-out line in the whole cedar tier and says what the maker thinks of its own timber. Against that stands the import route: dealer pricing, longer waits, and delivered costs that need pinning in writing. Worth the enquiry for buyers who want cedar as a cabin rather than a barrel, which the ranges above cannot offer.
Ideal for
- Cedar cabins, not just barrels
- The longest warranty in the category
- Wood-fired cedar configurations
Not ideal for
- Ordering from a price list
- Short lead times
- Entry-level budgets
- Material
- Clear western Canadian red cedar
- Forms
- Barrels and cabins
- Warranty
- 5 years
- Heating
- Electric or wood-fired, Harvia options
- Capacity
- 2–6 people by model
- UK route
- Specialist dealers
Heartwood Saunas Arbor X
8.7out of 10
Heartwood builds from FSC-certified timber grown in Wales and the wider UK, and the Arbor X is its flagship: an insulated cabin with a full-height glass wall, built to order rather than shipped from a container. Certified British timber in this category is rare enough to be the story.
Our verdict
Between the catalogue imports and the full commission sits this: a repeatable model, built in Britain from British-grown certified timber, with real insulation rather than bare staves. For buyers whose cedar question is really a provenance question, it is the strongest answer here. Pricing is per build, so the usual advice applies: fix the delivered scope in writing.
Ideal for
- FSC-certified British-grown timber
- Insulated walls and a glass elevation
- Buyers between kit and commission
Not ideal for
- List-price comparisons
- The lowest cost route into cedar
- Off-the-shelf delivery times
- Timber
- FSC-certified, Wales and UK grown

Almost Heaven barrel range
8.3out of 10
Solid cedar barrels from Harvia's American brand, manufactured since 1977 and paired with Harvia stoves, in electric and wood-fired configurations from 2 to 6 seats. UK availability runs through wellness dealers.
Our verdict
A known quantity in cedar: the timber is right, the stove pairing is right, and the heritage is real. It ranks fifth for the same reason it ranks last on our barrel list, which is that a buyer cannot see a UK price without an enquiry, and dealers set their own. If a quote comes back competitive with the Fonteyn range, the extra size options make it worth the wait.
Ideal for
- Cedar with Harvia stoves as one package
- Six-seat cedar barrels, rare elsewhere
- Buyers already using a wellness dealer
Not ideal for
- Price-first shortlists
- Quick UK delivery
- Anyone allergic to enquiry forms
- Material
- Cedar barrel construction
- Built since
- 1977
- Heating
- Harvia electric or wood-fired
- Capacity
- 2–6 people
- UK route
- Wellness dealers
- Pricing
- Dealer-set, per quote

What cedar actually buys
Western red cedar's oils do the job that a treatment schedule does on softwood: rot, insects and warp are handled by the timber itself, and the only decision left is cosmetic, whether to oil for amber or let it silver. Against the thermowood cabins that leadthe main outdoor ranking, cedar trades a little winter insulation for grain, scent and a shell that looks better at year five than year one.
The premium is real but narrower than assumed: the 4ft Fonteyn at £3,995 with its heater included undercuts several softwood cabins, and the cost gap only opens at the commission tier, where the money buys the build rather than the species.
Barrel cedar against cabin cedar
Most affordable cedar isbarrel-shaped, because staves suit the timber and the shape sheds British weather without asking the wood to do anything but exist. Cabin-form cedar, flat walls and L-shaped benches, lives almost entirely in the import and commission tiers, which is Dundalk's territory and the reason its range earns a place despite dealer-only pricing.
The choice is the usual one, plus scent: barrels heat faster and cost less, cabins seat more per metre and take a lying-down bench. Cedar just makes either version pleasant to stand next to.
Cedar at family size
Six and seven seats exist in cedar without a commission: the 8ft Fonteyn runs £6,295 with the heater in, and Dundalk and Almost Heaven both build to 6 seats through their dealer channels. A family weighing cedar against thefour person cabinsis mostly weighing bench layout against timber, since the prices overlap more than either tier admits.
At every size, cedar's weight sits close to softwood's, so the base requirement does not change: load-bearing, level, drained.
Buying quote-only cedar well
Three of the five entries here price per quote, which is normal for the category and manageable with one discipline: fix the delivered scope in writing, cabin, stove, controls, stones, delivery to postcode, and any crane or carry, before comparing numbers. A quote missing the stove is not a lower price, it is a different product, and spotting that is the core ofthe decisions that pick a saunaat this tier.
Lead times deserve the same treatment: dealer imports run weeks, commissions run months, and a build wanted for winter needs ordering while the garden is still in bloom.
Frequently asked questions
Why choose cedar for an outdoor sauna?
Western red cedar carries natural oils that resist rot, insects and warping, so a cedar shell lives outdoors without the yearly treatment softwood needs. It is also the scent most people mean when they remember a sauna.
How much does a cedar outdoor sauna cost in the UK?
Ready-made cedar starts at £3,995 for the 4ft Fonteyn barrel with the heater included and runs to £6,295 at 8ft. The commission tier, Out of the Valley and Heartwood, prices per project above that.
Does cedar need any maintenance at all?
Structurally, almost none: the timber weathers to silver-grey and keeps performing. Owners who want to keep the fresh amber colour oil it once or twice a year, which is a cosmetic choice rather than a preservation job.
Is cedar better than thermowood?
They solve the same problem differently. Thermowood is heat-treated to insulate and stabilise; cedar does its weatherproofing by chemistry and wins on scent and grain. Winter running cost slightly favours thick thermowood; looks and longevity untreated favour cedar.
Why is so much of the cedar market quote-only?
Because most cedar arrives as an import or a commission. Canadian makers sell through dealers who price delivery per postcode, and British workshops price per site. The Fonteyn range is the main exception with published UK prices.
Are cedar saunas sustainable?
Ask for the certification rather than the species. FSC-certified western red cedar exists, and Heartwood builds from FSC timber grown in Wales and the UK, which also removes the shipping leg entirely.
Do cedar saunas come with the heater included?
The Fonteyn barrels do at every size. The dealer and commission tiers specify the stove per order, so compare delivered quotes with the heater, controls and stones written in.
What base does a cedar sauna need?
The same as any outdoor sauna: level and load-bearing, concrete, paving on a sub-base or a reinforced deck. Cedar's rot resistance does not extend to standing water, so drainage around the base still matters.
How long does a cedar sauna last?
Decades is the honest answer when the base drains and the bands or fixings get their seasonal check. Dundalk's 5 year warranty is the category's longest written promise, and well-kept cedar outlives its paperwork.
Can I get a wood-fired cedar sauna?
Yes, through Dundalk and Almost Heaven, both of which offer Harvia wood-fired configurations. The published-price Fonteyn range is electric only.
