Outdoor infrared saunas
Best outdoor infrared saunas in the UK (2026)
Outdoor infrared is the shortest list in the UK sauna market: panel heat needs a weatherised building, and few makers bother to build one. Five do it credibly, from £3,171 to £15,999. These are those five, ranked.
Ranked on panel specification, weatherproofing of the shell, electrical demands, warranty terms and delivered UK cost.
The 5 best, ranked
Polar Eclipse 2 Person
9.2out of 10
The Eclipse puts infrared where it usually is not: outside. A weatherised two-seat garden cabin running panel heat at conversation temperature, £6,499.99 from the same Somerset warehouse and 4.8-rated Trustpilot operation behind our top-ranked Sauna Cube. Three sizes cover two, three and five bathers.
Our verdict
Outdoor infrared is a short list in the UK and this is its strongest entry: a real garden building rather than an indoor cabin gambled against the weather, priced £3,000 under the imported alternative, with UK stock and a maker whose after-sales record is scored in public. No stones and no steam, as ever with panels; that is the choice being made, not a flaw in it.
Ideal for
- Panel heat in a garden setting
- Long sessions at 30–65°C
- Recovery-focused daily users
Not ideal for
- Löyly and the water-on-stones ritual
- Budgets under £6,500

CenturaHeat 3 Person Outdoor Infrared
8.5out of 10
Three seats of outdoor infrared for £3,171: carbon-fibre panels totalling 3.5kW inside a hemlock cabin, running 18 to 65°C on a 16A hardwired supply. The 1500mm × 1100mm footprint keeps it inside small-garden territory, and the panel wattage keeps sessions at pennies.
Our verdict
Less than half the Eclipse's ticket for a third seat more, which makes it the value answer of the category. The gap is in the shell and the finish, hemlock panels rather than a weatherised premium build, so site it with some shelter and treat the exterior on schedule. As the affordable route into garden infrared it stands alone at this price.
Ideal for
- Outdoor infrared under £3,500
- Three bathers in a compact footprint
- Modest 16A electrical requirements
Not ideal for
- Fully exposed, wind-hammered sites
- Buyers wanting premium build quality
- Traditional-heat loyalists
- Price
- £3,171
- Panels
- 3.5kW carbon-fibre
- Temperature
- 18–65°C
- Footprint
- 1500mm × 1100mm, 2300mm tall
- Electrics
- 16A hardwired
- Material
- Canadian hemlock
CenturaHeat 4–6 Person Cube Hybrid
8.4out of 10
The hybrid runs both systems in one cube cabin: a 6kW stove for proper 90°C sessions and 3.5kW of infrared panels for gentle evenings, seating 4 to 6 at £5,569. The cost of having both is wiring, with separate 30A and 20A circuits to install.
Our verdict
For a household split between a steam loyalist and an infrared convert, this settles the argument in one building at a fair price for the capacity. The electrics are the real bill, two dedicated circuits, so get the install quoted before comparing tickets. Committed single-camp buyers do better spending the same money on the best version of their one heat.
Ideal for
- Households that want both heats
- 4–6 bathers in one cabin
- Testing infrared without giving up steam
Not ideal for
- Simple single-circuit installations
- Purists of either heat
- Minimal-wiring budgets
- Heating
- 6kW stove plus 3.5kW infrared
- Capacity
- 4–6 people
- Price
- £5,569
- Electrics
- Separate 30A and 20A circuits
- Size
- 2000mm × 1800mm × 2000mm
- Form
- Flat-pack cube cabin
Clearlight Sanctuary Outdoor 2
9.0out of 10
Clearlight's outdoor Sanctuary runs full-spectrum heaters, near, mid and far infrared together, inside a purpose-built two-seat garden cabin with a weather cover included, currently £9,599.20 against an £11,999 list, under a 25 year warranty. A 5 person version runs £15,999.
Our verdict
This is the endgame purchase of the category: the only full-spectrum outdoor cabin here and the longest cover, 25 years, at £3,100 over the Eclipse. That premium buys spectrum coverage and a warranty that outlasts most mortgages, not more seats. Buyers planning a decade of daily use can justify it; buyers still finding out whether infrared suits them cannot.
Ideal for
- Full-spectrum panels specifically
- The longest warranty in the category
- Decade-horizon daily users
Not ideal for
- First infrared experiments
- Budgets under £9,000
- Anyone content with far-infrared only
- Spectrum
- Near, mid and far infrared
- Capacity
- 2 people (5 person £15,999)
- Price
- £9,599.20, list £11,999
- Warranty
- 25 years
- Setting
- Purpose-built outdoor cabin, cover included
- UK route
- Clearlight UK
Sunlighten garden range
8.6out of 10
Sunlighten's SoloCarbon panels are the fit-out choice of commercial wellness studios, and its garden range brings the same panels and app-led session programmes outdoors, with a limited lifetime warranty behind them. UK buying runs through a dealer channel at quoted prices.
Our verdict
Studio-grade durability is a real signal, machines that survive commercial schedules survive families, and the app programmes are the most polished in the category. It ranks fifth on access alone: no UK list price, dealer quotes that land in Clearlight territory, and lead times set by the channel. Quote it against the Sanctuary and let the delivered numbers decide.
Ideal for
- Commercial-grade build for home use
- App-led session programming
- Buyers comparing at the premium tier
Not ideal for
- Published-price comparisons
- Quick delivery from stock
- Budgets under £6,000
- Panels
- Proprietary SoloCarbon
- Range
- Far infrared and full spectrum
- Warranty
- Limited lifetime
- Extras
- App control, session programmes

Built for outside, not moved outside
The category's defining fact is the shell. Panels themselves do not care about frost, but cabinetry, seals and electrics do, and an indoor cabin wheeled onto a patio fails at its first wet month. The entries here are garden buildings first, panel saunas second, which is also what separates this list fromthe general infrared rankings, where socket-powered indoor cabins from £1,500 make the running.
Weatherisation is also where the price spread comes from: £3,171 buys real panels in a hemlock shell that prefers a sheltered corner, while the premium tier builds for full exposure.
Panel heat is a different evening
A stove sauna is 15 minute rounds at 90°C with cool-downs between; panels run 30 to 45 continuous minutes at 40 to 65°C, warm bodies rather than air, and cost 40p to 90p a session doing it. Neither reproduces the other, andhow the two heats differis worth understanding before spending £6,500 on either, because the buyers who regret their sauna almost always bought the wrong heat, not the wrong brand.
The practical tells: people who love the löyly ritual want stones; people who want a nightly 40 minute decompression, or share the cabin with someone heat-averse, want panels.
What the evidence does and does not cover
The long-run cohort data behind saunahealth claims comes from Finnish stove saunas used at 80°C and above, while infrared's own trial literature is younger and smaller, mostly around heart function, pain and fatigue. Both heats raise core temperature and heart rate, which is the mechanism researchers point to; neither body of evidence crowns a winner, and no cabin at any price is medicine.
Buy the heat you will actually sit in three times a week. Frequency, not spectrum, is the variable every study agrees on.
Where the stove cabin still wins
Group bathing, steam, and the 90°C hit stay with the stove cabins that leadthe main outdoor ranking: five seats behind thermowood costs £5,499.99 there, £1,000 under this category's two-seat pick, and no panel cabin fills with löyly when the water hits. Buyers wanting the garden building without the panel commitment have that list; buyers reading this one already know why they are here.
Frequently asked questions
Can infrared saunas go outside?
Only if they are built for it. Outdoor infrared cabins carry weatherised shells, sealed electrics and roofing that an indoor cabin lacks, and every entry in this ranking is a purpose-built garden unit. Putting an indoor infrared cabin outside voids it, usually quickly.
How much does an outdoor infrared sauna cost in the UK?
This ranking runs from £3,171 for three seats of carbon panels to £15,999 for the 5 person full-spectrum flagship. The lead pick sits at £6,499.99 for two seats with 3 and 5 person sizes above it.
How hot does an outdoor infrared sauna get?
Panels run the cabin at 18 to 65°C and heat you directly rather than the air, which is the point: sessions run 30 to 45 minutes at temperatures you can talk through, instead of short rounds at 80 to 100°C.
What does an infrared session cost to run?
Panel wattages of 1.6kW to 3.5kW mean roughly 40p to 90p per session at the 26.11p per kWh cap rate, against about £1.57 in a 6kW stove cabin. Frequent users feel that gap; weekend users barely do.
Do outdoor infrared saunas need an electrician?
Mostly yes at this size: the 3.5kW cabins hardwire to a 16A supply, and the hybrid needs two circuits. It is lighter electrical work than a stove cabin's 32A run, but it is still notifiable and still a registered electrician's job.
Does infrared work in a British winter?
Yes, with a caveat: panels heat bodies, not air, so the cabin interior stays cooler than a stove sauna and a weatherised shell matters more, not less. The premium builds hold their session temperature in frost; the value builds prefer a sheltered site.
What is full spectrum infrared?
Panels emitting near, mid and far infrared together rather than far only. In this ranking full spectrum exists only at the Clearlight tier from £9,599.20. Far infrared is what everything else runs, and it is what the bulk of home-use evidence is based on.
Is a hybrid sauna worth it?
For a household split between steam and panels, one £5,569 building beats buying twice. For anyone committed to a single heat, the same money buys a better version of that one heat.
Do I need planning permission for an outdoor infrared cabin?
The rules are the same as any garden building: usually fine in England under permitted development at up to 2.5m tall within 2m of a boundary. The panel electrics make no difference to planning.
Infrared or traditional for the garden?
Traditional gives the 90°C hit, the steam and the ritual; infrared gives long, gentle, cheap sessions with no stove to manage. It is a preference split, not a quality split, and the wrong answer is the one you will not use three times a week.
