A home sauna brings dry, radiant heat into your house or garden to ease tired muscles, support sleep and turn recovery into a daily habit. UK buyers choose between four main types: infrared cabins that warm the body directly at lower temperatures, and traditional steam saunas in barrel, garden or larger outdoor form. Guide prices run from about £1,800 for a two-person infrared cabin to £4,500 or more for a traditional outdoor cabin, before installation. This page compares all four, what each costs to buy and run, and how to choose the one that fits your space and budget.
Radiant panels warm your body directly at 45 to 60°C, so it runs cooler and cheaper than steam. The most efficient home type, and many models plug into a normal socket indoors.
A curved cedar or thermowood cabin that heats fast and sits on level ground with almost no groundwork. The easiest and best-value route into a traditional garden sauna.
Compact, design-led cabins for smaller plots that reach a full 70 to 90°C with an electric or wood stove. A tidy centrepiece where a big cabin will not fit.
Larger traditional cabins for the garden, with room for four to six and the highest heat. The most authentic steam experience, and the biggest install.
Pre-cut panels or logs, benches and door on a pallet, built by two people over a weekend. The cheapest route to a proper sauna if you can do the assembly and arrange the electrics.
How the four main home sauna types compare on price, heat and effort. Guide prices are indicative.
| Compare | Infrared | Barrel | Garden | Outdoor |
|---|---|---|---|---|
| Guide price | From £1,800 | From £3,200 | From £3,900 | From £4,500 |
| Typical heat | 45 to 60°C | 70 to 90°C | 70 to 90°C | 70 to 110°C |
| Install effort | Plug in, easiest | Low, minimal base | Medium, level base and power | Medium to high, base and often a dedicated circuit |
| Best for | Indoor use and lowest running cost | Best-value garden sauna | Compact, design-led plots | Larger cabins and the most authentic steam |

Infrared cabins suit an indoor room; barrel, garden and outdoor saunas go in the garden. Measure your space and delivery access before you buy.
Infrared panels run cooler and cheapest; an electric stove gives authentic steam and may need a dedicated circuit; a wood-burner is off-grid but needs a flue.
One to two person cabins suit couples and small spaces. Four to six person cabins work as a family sauna or a garden centrepiece.
Infrared costs the least to run and a larger electric stove the most, so check the heater's kW draw and compare it against your electricity rate.
Cedar and thermowood stand up to UK weather. Check insulation, stave thickness and build quality if the cabin lives outdoors year-round.
Anything above roughly 3 kW should be checked by a qualified electrician, and fixed wiring is notifiable under Building Regulations Part P.
Before you buy: sauna heat and your health
What the research really supports for the heart, relaxation and recovery, what is only promising, and what a sauna will not do, with the risks worth knowing first.
The safe, beginner-friendly method for using a home sauna: how hot to set it, how long to stay in, rounds, hydration, what to expect, and who should check with a GP first.
An honest DIY sauna guide: the three routes (build, kit or buy), what a build involves, heater sizing, the Part P electrics and real UK costs.
Heat then cold is where real recovery happens. Add an ice bath for the cold half of contrast therapy, finishing on cold.
There are four main types. An infrared sauna warms your body directly with radiant panels at a lower 45 to 60°C, runs cheaply and is the easiest to site indoors. A barrel sauna is a curved outdoor cabin that heats fast and installs with minimal groundwork, the best-value route to traditional steam heat. A garden sauna is a compact, design-led cabin for smaller plots, and an outdoor sauna is a larger traditional cabin for the garden with the highest heat and the most room. Barrel, garden and outdoor saunas all reach a full 70 to 110°C with an electric or wood stove.
As a guide, a usable two-person infrared cabin starts around £1,800, a barrel sauna from about £3,200, a garden cabin from about £3,900, and a larger traditional outdoor cabin from about £4,500, with big or bespoke cabins running to £6,000 or more. Smaller single-person infrared cabins start lower, from around £1,200. Those are cabin prices before delivery, a base if you need one, and installation. Guide prices, not live prices.
It depends on the heater's power and your electricity rate. At the Ofgem price-cap rate of 26.32p per kWh for 1 October to 31 December 2026, a 2 kW infrared panel costs about 53p an hour at full draw, a 6 kW electric or barrel stove about £1.58 an hour, and a 9 kW cabin stove about £2.37 an hour. Real sessions usually cost less, because once up to temperature the thermostat cycles the heater on and off rather than drawing continuously. A wood-burner costs only firewood plus a little electricity for lighting. Guide figures, correct as of October 2026, and the cap changes quarterly.
Infrared if you want the lowest running cost, a gentler 45 to 60°C, and the easiest indoor install, often plugging into a normal socket. Traditional (barrel, garden or outdoor) if you want authentic high heat and steam, poured over hot stones at 70 to 110°C, and you have garden space and a suitable power supply. Infrared warms you; traditional heat warms the room around you, and the feel is quite different.
Infrared cabins run cooler, roughly 45 to 60°C, warming you with radiant panels. Traditional barrel, garden and outdoor saunas run hotter, about 70 to 110°C, heating the air and stones. As for how long, general guidance is short sessions of around 15 to 20 minutes, building up gradually and listening to your body rather than pushing it. For a full routine, see our guide on how to use a sauna.
For the electrics, yes: an electric stove above roughly 3 kW usually needs a dedicated circuit, and any fixed wiring is notifiable under Building Regulations Part P and must be done by a qualified electrician. For planning, a garden cabin in England often falls under permitted development within height and siting limits, but listed buildings and designated land such as conservation areas and National Parks are exceptions, and Scotland, Wales and Northern Ireland differ, so check with your local planning authority.
Not meaningfully. A sauna makes you sweat, so the scales may drop straight after a session, but that is water you regain as soon as you rehydrate. It does not burn fat or cause lasting weight loss, and it will not "detox" your body. The genuine draws are muscle relaxation, comfort, and for some people better sleep.
Regular sauna use is linked to lower cardiovascular and all-cause mortality in Finnish cohort research, and many people find it relaxing and helpful for sleep. That evidence is observational and mostly from traditional saunas, so it shows an association, not proof that saunas cause the benefit, and it may not transfer directly to infrared. Saunas are not for everyone: speak to your GP first if you have a heart condition, poorly controlled high blood pressure or low blood pressure, and read the risks above. This is general guidance, not medical advice.
Take care. Heat raises your core body temperature, and overheating in pregnancy can be harmful, so the cautious approach is to avoid it or stay well within comfortable limits. Speak to your GP or midwife before using a sauna while pregnant.
