118 outdoor saunas listed for up to four people, from £2,300, with the size, height and heater each retailer states.
These are the 118 outdoor saunas in our dataset that the retailer lists for up to four people, from 18 UK retailers, with prices from £2,300 to £29,999 and a median of £5,993. Where a listing gives a range, such as “2–4 person”, we count the top figure, so treat four as the most it seats, not the number who’ll have room to stretch out. Every price was checked on 30 September 2026. Sauna tents are left out: see sauna tents.

Prices include VAT. Each row shows the date we checked it against the retailer's own page; the latest check was 30 September 2026. Prices change: the retailer's checkout price is what counts. Height chips show the retailer's stated height: green 2.5 m or lower, amber taller. That's before your base, and it isn't a planning check (see why 2.5 m matters). “Not recorded” means we could not confirm the figure on the retailer's page.
The median 4 person sauna in our data costs £5,993, but that mixes saunas sold with a heater and without. With a heater in the price the median is £4,946 across 29 listings; without one it’s £5,841 across 73. By type:
| Type | Listings | From | Median |
|---|---|---|---|
| Barrel | 52 | £2,300 | £5,185 |
| Cabin | 40 | £3,763 | £7,725 |
| Cube | 20 | £3,289 | £5,425 |
| Pod | 4 | £5,450 | £8,088 |
| Infrared | 2 | £3,240 | £5,117 |
The ticket price leaves out the base, the electrics and, often, assembly. Add them up with the garden sauna cost calculator.
Across the 4 person saunas with a stated size, the median footprint is 5.2 m², with a median length of 2.36 m and a median width of 2.20 m. The smallest are:

Leave room to walk round it and for the door to open. Enter your space into the sauna finder to see which models fit.
Of the 83 with a stated height, 71 are 2.5 m or lower and 12 are taller. In England and Wales, an outbuilding within 2 m of a boundary must be no more than 2.5 m high overall to be permitted development, and that includes the base. Test your own garden with the planning permission checker.

Where the heater’s output is stated, the 4 person saunas here come with 2 kW to 9 kW, and the median is 6.8 kW. Heater makers size by the room’s volume, not the seat count: Harvia’s rule of thumb is about 1 kW for each cubic metre, with extra for glass and uninsulated walls. Work yours out with the heater size calculator, then see what that output draws with the electrical supply calculator.
