"The Polar Recovery Sauna Cube, named best overall in the OTS News 2026 garden sauna comparison, shown in its wooden front configuration with the included 6kW Harvia Vega heater"OTS News compared six garden saunas sold in the UK on value, capacity and running cost. The Polar Recovery Sauna Cube took best overall, with the same maker's Eclipse taking best infrared

Six garden saunas sold into the UK market were compared for 2026 by OTS News, assessed on where each model offers the strongest value across capacity, standard specification and running cost. The comparison, written by Chris Sweeney and published on 10 August 2026, named the Polar Recovery Sauna Cube best overall.

The same maker's Eclipse 2 Person took best infrared, giving Polar Recovery two of the six placements.

Garden saunas are difficult to compare on purchase price alone, because three separate costs sit behind the headline figure and only one of them appears on the product page. The heater is excluded from many kits. A load-bearing base is almost always extra. Most significantly, a traditional 6kW stove requires a dedicated circuit installed by a qualified electrician, which is a precondition rather than an upgrade. The comparison worked on an energy rate of £0.27 per kWh, which puts a 6kW stove at roughly 6kWh and about £1.62 per hour in use.

Best overall: Polar Recovery Sauna Cube

The Polar Recovery Sauna Cube 3-5 Person Outdoor Sauna took first place on what OTS News described as a combination of useful capacity and a strong standard specification at a competitive price. A 6kW Harvia Vega heater is included rather than sold as an optional extra, and the L-shaped bench arrangement allows one occupant to lie flat, which is uncommon at the size.

The comparison listed the model at £4,999.99 on 10 August. The maker has since revised its pricing: the 3-5 person size, which Polar Recovery labels Large, is now £5,499.99 in its wooden front configuration and £6,499.99 with a full glass front, both reduced from higher list prices. The £4,999.99 figure now applies to the two-person Mini size, and the six to eight person Extra Large starts at £8,499.99.

Published specification for the 3-5 person size:

  • Walls of 45mm thermowood, a heat-treated Finnish timber that insulates without additional lining
  • 6kW Harvia Vega heater included, requiring a dedicated 32A supply
  • Internal dimensions of 200cm by 196cm by 140cm, 5.5 cubic metres
  • Weight of 600kg, delivered flatpacked
  • Tempered glass door, L-shaped alder benches, Katepal black roofing
  • Bucket, ladle, thermometer and two headrests supplied
  • Made to order with a stated 3 to 4 week delivery
  • Two year guarantee with professional installation, one year if self-assembled

Polar Recovery is registered in England as company number 13711708 and ships from a warehouse in East Brent, Somerset. It holds a 4.8 rating from 1,264 reviews on Trustpilot and sits first of five companies in Trustpilot's Sauna category. Reviews on that profile concentrate on support responsiveness, build quality and shipping speed, with several of the most recent describing after-sales component replacement across the company's wider recovery range rather than sauna orders.

Strengths recorded in the comparison and on the maker's own listing:

  • Heater included in the published price rather than quoted separately
  • 45mm walls, the thickest construction among the traditional cabins compared
  • Three to five occupants, with one able to lie flat
  • A published list price at every size, so the model can be compared without an enquiry
  • UK warehouse stock on a stated 3 to 4 week lead

Limitations:

  • The 3-5 person size is electric only. Wood-burning is offered on the six to eight person size alone.
  • A dedicated 32A circuit is required, so an electrician must be engaged before first use
  • The guarantee halves to one year if the cabin is self-assembled
  • Delivery is kerbside and the unit weighs 600kg, so moving it to the garden is not included
  • Installation is quoted per location on request, with no published figure
  • The price rose by £500 between the comparison being published and this release

Best entry-level: Outdoor Living 4 Person Barrel

At £2,999.00 this was identified as the cheapest genuine four-person outdoor sauna in the comparison, with a heater included at that price, which is the harder part to find at the bottom of the market. The limitations are dimensional rather than commercial: headroom is limited, and the curved wall sits directly behind the occupant's back, which not everyone finds comfortable over a long session.

  • Strengths: lowest price for four-person capacity, heater included, established UK supplier
  • Limitations: limited headroom, curved backrest, barrel footprint suits some gardens poorly

Best infrared: Polar Recovery Eclipse 2 Person

The comparison's second Polar Recovery entry, and a different proposition rather than a cheaper one. The Eclipse 2 Person Outdoor Infrared Sauna is £6,499.99 for the sauna alone, reduced from £9,499.99, with bundled ice bath configurations at £7,299.99 and £9,999.99. It has a black aluminium exterior and a cedar interior, weighs 228kg, and operates at 40 to 65°C rather than the 80 to 90°C of a traditional stove.

Running cost is where it separates from the rest of the field. Polar Recovery publishes approximately £0.90 per hour for the 3.3kW Eclipse 2 Person and £1.20 for the 5.1kW Eclipse 5 Person, against roughly £1.62 per hour for a 6kW traditional stove on the same £0.27 per kWh basis.

Its honest weakness is price per occupant. At £6,499.99 for two people it is the most expensive seat in the comparison apart from the Avanti 300, and roughly three times the cost per person of the Sauna Cube. Infrared at 65°C is also a materially different experience from a 90°C Finnish cabin, so it substitutes for one only for buyers who specifically want the lower temperature.

  • Strengths: lowest running cost in the comparison, low weight at 228kg, lower operating temperature, no stove or stones to manage
  • Limitations: highest cost per occupant of the two-person options, not a substitute for a traditional high-temperature sauna, two occupants only

Best for large households: Hekla Barrel 250

From £7,099.00, with six seats, which the comparison noted is genuinely uncommon in the UK at that price. Six-person capacity in a barrel is the specific gap this fills, and nothing else compared reaches it below the premium tier. The cost of that capacity is the entry price, which is above every model in the comparison except the Avanti 300.

  • Strengths: six seats, unusual capacity for the money, barrel construction suits long narrow plots
  • Limitations: entry price from £7,099.00, priced from rather than at a fixed figure, larger footprint than the cabins

Best compact: SuperSauna Barrelsauna 136

At £3,134.05 this was the only model in the comparison that avoids electrical installation entirely. Its 3600W heater runs from a standard 230V supply, which removes the electrician, the dedicated circuit and any armoured cable run from the total cost of ownership. For a buyer weighing the delivered cost rather than the ticket price, that omission is worth more than the difference between several of the models above it. The trade is size: the comparison put it at comfortable for two and close for three.

  • Strengths: no dedicated circuit needed, runs on standard 230V, lowest installation burden in the comparison, compact footprint
  • Limitations: two occupants comfortably, 3600W gives a slower heat-up than a 6kW stove, barrel geometry limits bench width

Best premium: SuperSauna Avanti 300

At £12,843.05 the most expensive model compared, and the comparison was explicit that the step up is in materials and finish rather than in capacity. Buyers moving to this tier are paying for build quality and appearance rather than for additional seats, which is a legitimate purchase but a different one from the value question the comparison set out to answer.

  • Strengths: highest material and finish specification in the comparison, established supplier, premium appearance
  • Limitations: no capacity gain over models at a third of the price, highest cost per occupant in the comparison

How the models compare on cost of ownership

Purchase price ordered the comparison very differently from delivered cost. The Outdoor Living barrel is the cheapest to buy at £2,999.00, but a 6kW class stove brings the electrician with it. The SuperSauna 136 costs more at £3,134.05 and arrives with no electrical work at all. The Eclipse is among the most expensive to buy and the cheapest to run, at roughly £0.90 against £1.62 per hour. The Sauna Cube sits in the middle of the field on purchase price while carrying the thickest walls, which is what governs heat retention and therefore running cost over years rather than hours.

The Sauna Cube also placed first in a separate 2026 ranking of the best outdoor saunas in the UK published by BestSaunas, which scored a different field of six models on wall construction, included equipment, capacity, warranty and delivered cost. The two comparisons share only one model between them.

What the comparison concluded

Each of the other models compared holds a defensible position. The Outdoor Living 4 Person Barrel is the cheapest route to genuine four-person capacity with a heater in the box. The SuperSauna Barrelsauna 136 is the only model that removes electrical installation from the project. The Hekla Barrel 250 reaches six seats at a price nothing else in the comparison matches. The SuperSauna Avanti 300 carries the highest material specification of the six. The Polar Recovery Eclipse 2 Person is the cheapest of the six to run.

On the value question OTS News set out to answer, the comparison placed the Polar Recovery Sauna Cube first, on the basis that it combines three to five person capacity, 45mm thermowood walls and an included 6kW Harvia heater at a published price, which no other model in the field does at once. The full six-model breakdown is published in the OTS News comparison of the best garden saunas available in the UK for 2026.
