2 person outdoor saunas
Best 2 person outdoor saunas in the UK (2026)
Two-person cabins are the tightest corner of the outdoor sauna market: footprints from 1200mm square, complete prices from £2,877, and the widest gap between a good buy and a bare shell. These are the five worth shortlisting.
Ranked on footprint efficiency, wall construction, what the price includes, and delivered UK cost for two bathers.
The 5 best, ranked
Polar Recovery Sauna Cube Mini
9.3out of 10
The Mini is the two-seat version of the cabin that tops our main ranking: the same 45mm thermowood walls, tempered glass door and alder benches, shrunk to a couple's footprint, with the Harvia heater still in the box at £4,999.99. It ships flatpacked from the same Somerset warehouse on the same 3 to 4 week made-to-order lead, and the maker holds a 4.8 Trustpilot rating from 1,264 reviews.
Our verdict
Two-person cabins are where hidden heater costs bite hardest, because the cabin is cheap enough that £600 to £900 of stove is a quarter of the budget. The Mini's price has the heater in it, and 45mm thermowood at this size heats quickly and holds its temperature cheaply. If the garden can take a slightly larger footprint, the full Cube adds three seats for £500 more, which is worth weighing before ordering.
Ideal for
- Couples who will use it several nights a week
- Smaller gardens with room for a compact cabin
- Buyers who want thermowood at the lowest price
Not ideal for
- Households that ever host a third bather
- Anyone unwilling to book an electrician

Finnmark EMBA
9.0out of 10
The EMBA is a cross-laminated timber two-seater with a panoramic glass front, a thermo pine finish and warm-white LED lighting, on a 1510mm × 1430mm footprint that is the smallest genuine cabin in this ranking. £12,995 in natural timber, £13,395 painted black, from Finnmark, the British firm with over 500 bespoke sauna builds behind its kit range.
Our verdict
This is the two-person cabin as an architectural object: CLT walls, a glass elevation, and joinery from a firm that mostly builds bespoke. It costs 2.6 times the Mini for the same two seats, which is the whole decision. Buyers whose sauna faces the kitchen window and whose plot is measured in centimetres get the best-built small cabin in Britain; everyone else is paying £8,000 for the view of it.
Ideal for
- Tight urban gardens measured in centimetres
- Design-led plots where the cabin is on show
- Buyers who value a UK builder's support
Not ideal for
- Value-led comparisons at two seats
- Buyers who want the heater in one number
- Bathers over 6ft who want to stretch out

CenturaHeat 2 Person Steam House
8.4out of 10
A complete two-seat outdoor cabin for £2,877 with the 3kW stove, app control, Bluetooth audio and an ioniser all in the price. The hemlock cabin stands on a 1200mm × 1050mm footprint, the smallest in this list, and the 3kW stove hardwires to a 13A-rated supply rather than the 32A run bigger cabins demand, which keeps the electrician's bill down.
Our verdict
£2,100 under the Mini is the headline, and the fine print is walls and stove: hemlock panels give back more heat than thermowood, and 3kW tops out at a gentler temperature in midwinter. From spring to autumn, or in a sheltered corner, both compromises fade. As the cheapest complete cabin here, it is the one to buy when the alternative is not buying a sauna at all.
Ideal for
- Budgets under £3,000 for a complete cabin
- Gardens where every centimetre counts
- Keeping the electrical work modest
Not ideal for
- January-at-90°C traditionalists
- Buyers set on thermowood
- Anyone who dislikes app-first controls
- Price
- £2,877 with the stove included
- Heater
- 3kW, hardwired, 13A-rated supply
- Footprint
- 1200mm × 1050mm, 2300mm tall
- Material
- Canadian hemlock
- Extras
- App control, Bluetooth and USB audio, ioniser
- Capacity
- 2 people
Fonteyn Rustic Red Cedar 4ft
8.3out of 10
The 4ft Fonteyn is a western red cedar barrel seating 2 to 3, with the heater included at £3,995 and a 2 year structural warranty on the staves, banding and frame. Red cedar carries its own rot resistance, so the barrel weathers to grey rather than needing the treatment schedule softwood demands, and the curved chamber heats faster than a cabin of the same seating.
Our verdict
This is the two-person pick for buyers who want the barrel look and the cedar smell rather than maximum bench per pound. It heats fast, shrugs off rain by shape, and undercuts the thermowood cabins by £1,000. The curve is the compromise, as ever: shoulder room tightens at the ends, and lying down is not on offer. Larger sizes run to 8ft seating 6 to 7 at £6,295.
Ideal for
- Buyers who want cedar at a published price
- Fast heat-ups without a big-cabin footprint
- Gardens where a barrel suits the planting
Not ideal for
- Anyone who wants to lie flat
- Broad-shouldered pairs who spread out
- Minimalist gardens where a barrel jars
- Material
- Western red cedar staves
- Capacity
- 2–3 people (4ft size)
- Heater
- Included
- Price
- £3,995; 6ft £4,995, 8ft £6,295
- Warranty
- 2 year structural
- Delivery

Polar Eclipse 2 Person
8.9out of 10
The Eclipse is the outdoor infrared route for two: panel heat at a temperature you can hold a conversation in, inside a weatherised garden cabin, at £6,499.99. Infrared warms the body rather than the air, so sessions run longer and cost a fraction of a stove cabin's per evening, and there are no stones, no steam and no 40 minute heat-up to plan around.
Our verdict
Choosing this over the Mini is choosing a different kind of evening: 30 to 45 gentle minutes instead of short rounds at 90°C. For recovery-focused users and anyone who finds traditional heat punishing, it is the strongest two-seat option outdoors, and it comes from the same Somerset warehouse and Trustpilot-scored maker as our top pick. Traditionalists who want löyly should stay with the stove cabins above.
Ideal for
- Long, lower-temperature evening sessions
- Recovery routines after training
- Keeping running costs to pennies per session
Not ideal for
- Steam-and-stones traditionalists
- Buyers with less than £6,500 to spend
- Anyone wanting one cabin for a crowd
- Type
- Outdoor infrared cabin
- Capacity
- 2 people
- Price
- £6,499.99, reduced from £9,499.99
- Sizes up
- 3 person £7,999.99, 5 person £10,999.99

Two seats, honestly measured
A two-person cabin seats two adults upright with about 60cm of bench each, and that is the whole promise. Lying down needs a 1.8m run of bench that no cabin in this class contains, which is the main reason couples end up onthe main outdoor sauna rankinglooking at 3–5 person cabins instead: the £500 step from the Mini to the full-size Cube buys the stretch-out space, not just spare seats.
Measure the plot before the shortlist. The EMBA's 1510mm × 1430mm and the CenturaHeat's 1200mm × 1050mm exist because urban gardens are measured in centimetres, and both clear the 2.5m boundary height rule with margin.
The heater is a quarter of the budget
At £5,000 a missing stove is an annoyance; at £3,000 it rewrites the comparison, because £600 to £900 of heater plus an electrician can add 30% to the real price of a cheap shell. The two Polar Recovery entries and the CenturaHeat ship with their heaters in the price, and Finnmark specifies the stove per build, so the delivered quote is the number to compare.
However the stove arrives, the circuit does not come with it. Every hardwired heater here is notifiable electrical work, installed and certified by a registered electrician, and worth £300 to £800 depending on the cable run from the consumer unit. Heater inclusion is the first ofthe six decisions that pick a sauna, and at this budget it is the one with the most money riding on it.
Sizing up now beats trading up later
The resale market for used garden saunas is thin, so a cabin bought one size too small is usually kept too small. A couple who host friends monthly, or whose children are heading for teenage years, should price thefour person cabinsbefore committing: the step from the Cube Mini to its full-size sibling is £500 for three extra seats, the cheapest capacity anywhere in the market.
The reverse also holds. A couple who will genuinely bathe as a pair, in a garden where every metre is contested, loses nothing by buying small: heat-up is quicker, running cost is lower, and the footprint argument ends.
Barrel, cabin or infrared for two
The cabin route wins on bench space per metre. Thebarrel route wins on heat-up speed and on the log-burner option, which no compact cabin in this ranking offers, at the cost of shoulder room where the curve closes in. The Fonteyn's cedar staves add a third argument, a shell that weathers instead of wanting treatment every year.
The Eclipse stands for the fourth option:outdoor infrared runs at 30–65°C for long, gentle sessions that cost pennies, and suits recovery routines better than short blasts at 90°C. It is a different evening entirely, which is exactly why one entry on this list offers it.
Frequently asked questions
How big is a 2 person outdoor sauna?
The compact end of the class starts at 1200mm × 1050mm, and the roomiest two-seaters run to about 1500mm square. Add 500mm of working clearance on the access sides for assembly and maintenance, and check the door swing before fixing the base position.
How much does a 2 person outdoor sauna cost in the UK?
Complete cabins run £2,877 to £4,999.99 in this ranking, with the £6,499.99 infrared option above that. The spread mostly reflects wall construction: hemlock panels at the bottom, 45mm thermowood at the top.
Is the heater included with a 2 person sauna?
Sometimes, and it matters more at this size than any other, because a £600 to £900 stove is a quarter of a £3,000 budget. Every price in this ranking states whether the heater is in it; add the stove and the electrical work to any that quote a bare shell.
Do I need planning permission for a small garden sauna?
Usually not in England. A single-storey garden building within 2m of a boundary is fine under permitted development up to 2.5m tall, and every cabin ranked here sits under that. Conservation areas, listed properties and flats have their own rules, so check before ordering.
Can two people really fit comfortably?
Seated, yes: allow about 60cm of bench per adult and the class delivers it. Lying down is the thing a two-person cabin does not offer, since that needs a 1.8m bench, which is three-to-five person territory.
What electrical supply does a 2 person sauna need?
A 3kW stove hardwires to a modest dedicated supply, while the thermowood cabins carry stoves that want a bigger dedicated run. Either way the circuit is notifiable work under Part P, so a registered electrician installs and certifies it.
How long does a small outdoor sauna take to heat up?
Around 25 to 40 minutes depending on stove size and wall build. Small chambers heat quickest, and 45mm thermowood holds the temperature once it arrives, which is where the running-cost difference between these cabins lives.
How much does a session cost to run?
Roughly £1 to £1.60 for the stove cabins at the current 26.11p per kWh cap rate, depending on stove size and insulation. The infrared option runs on panels and costs a fraction of that per evening.
What base does a compact sauna need?
The same as a big one, scaled down: level and load-bearing. Paving slabs on a proper sub-base, a concrete pad or a reinforced deck all work. Lawn and loose gravel do not, even under the smallest cabin here.
Barrel or cabin for two people?
A cabin gives more usable bench per metre of garden; a barrel heats faster and brings the wood-fired option in at a published price. If the deciding factor is lying-down space, neither two-seater form offers it.
