Quick answer
For the closest match to the Finnish research linking regular sauna use with heart health, choose a traditional sauna: our top pick is the Finnmark Micro Thermowood Barrel Sauna. Infrared cabins are gentler but have only small trials, and the Finnish findings are associations, not proof that saunas themselves improve health.
Our picks
Finnmark Micro Thermowood Barrel Sauna (2 Person)
Finnmark Sauna
- • £5,371 with 6kW electric heater (£3,995 kit only)
- • 40mm thermally modified spruce
Honest caveat: It is an uninsulated outdoor structure, so heat-up is slower in a British winter, and a 6kW heater needs a dedicated hardwired supply. The timber warranty is two years. You assemble it yourself or pay for installation.
£5,371
Finnmark Sauna
Clearlight Sanctuary 1 Person Infrared Sauna
Clearlight Saunas UK
- • Publishes EMF readings (brand-measured)
- • FSC-certified okoume wood
Honest caveat: The EMF figures are the brand’s own, with no named lab, and the page contradicts itself (calling 3 mG a WHO ’threshold’ while listing 7 to 8 mG at the front heaters). The UK site shows ’request pricing’; £8,999 is the listed store price at the time of checking. The warranty does not cover on-site labour.
£8,999
Clearlight Saunas
LUMI Therapy Sauna PRO (1 Person)
LUMI Therapy
- • £2,799 (was £3,499)
- • Hemlock wood, carbon far-infrared panels
Honest caveat: The page gives no EMF figures and no CE or UKCA details, and the warranty is only one year, which is short for a £2,800 appliance. It draws up to 2,150W, so check your socket and circuit with an electrician.

Infrared cabin or traditional sauna?
The research that most people quote comes from traditional Finnish saunas: hot, dry rooms at around 80°C or more, heated by an electric or wood stove, sometimes with water thrown on the stones for steam. In a 20-year study of about 2,300 men in eastern Finland, those who used a sauna four to seven times a week had lower rates of fatal heart disease and death from any cause than those who used one once a week (Laukkanen et al. 2015). This is an association, not proof that saunas are responsible, but it is the strongest evidence there is.
Infrared cabins heat your body directly with panels, so the air stays cooler, usually 40 to 65°C. Many people find them easier to tolerate. The trials are smaller and mostly involve patients with heart failure (PubMed), so the evidence is Early.
If you want to match the Finnish research as closely as possible, choose a traditional sauna. If you prefer gentler heat, an infrared cabin is closer to the trials than a sauna blanket, because you sit upright and can step out easily. For the evidence in detail, read our sauna benefits guide.
How we chose
We looked for cabins and saunas sold in pounds to UK buyers, checked in October 2026, and compared them on published EMF data, materials, electrical requirements, temperature range and warranty. UKCA and CE marks are mostly self-declared, so we gave more weight to named standards and measured figures.
The picks
Finnmark Micro Thermowood Barrel Sauna: best traditional sauna
If you want what the Finnish studies looked at, this is it: a two-person outdoor barrel in 40mm thermally modified spruce (heat and steam treated, not chemically preserved), £5,371 with a 6kW electric heater or £3,995 without. Caveat: it is uninsulated, so it is slower to heat in winter, and it needs garden space, a hardwired electrical supply fitted by an electrician, and assembly. The timber warranty is two years.
Clearlight Sanctuary 1: best for published EMF data
The only product we found with actual magnetic field figures: 1.5 mG (0.15 µT) at the far-infrared heater surface and 7 to 8 mG at the front full-spectrum heaters, falling to near zero within about 10cm. It is built from FSC okoume wood, runs from a UK 13A plug and carries a 25-year residential parts warranty. Caveat: the figures are the brand's own, with no named lab, and the page calls 3 mG a WHO threshold, which it is not. It was listed at £8,999 at our check, and the UK site asks you to request a quote.
LUMI Therapy Sauna PRO: best mid-price infrared cabin
A one-person hemlock cabin with carbon far-infrared panels, 30 to 65°C, at £2,799. Caveat: no EMF figures, no UKCA or CE details on the page, and only a one-year warranty. It draws up to 2,150W, so check your circuit.
What do EMF figures mean for a cabin?
Magnetic fields from heating panels fall away quickly with distance. UKHSA puts typical UK home background levels at about 0.01 to 0.2 µT, and the public guideline it follows is 100 µT. A figure is only useful with a distance, so Clearlight's surface and 10cm readings are more helpful than "low EMF" with no number.
Before you buy
- Electrics: traditional heaters of 6kW or more need a dedicated hardwired circuit. Cabins with a 13A plug are simpler. Ask an electrician either way.
- Space and ventilation: indoor cabins need a dry, ventilated room. Outdoor saunas need a level base and planning checks if they are large.
- Materials: solid timber with no glued panels is a better sign than MDF. FSC certification covers forestry, not emissions.
- Running costs: a 6kW heater for an hour uses about 6kWh, plus warm-up time.
Who should take advice first
Speak to your GP before regular sauna use if you are pregnant, have heart disease, unstable blood pressure, a pacemaker or other implant, or take medicines that affect blood pressure or sweating. NHS guidance advises avoiding significant overheating during pregnancy. Avoid saunas after alcohol, and drink water before and after. Stop at the first sign of heat exhaustion.
Bottom line
For the closest match to the research, a traditional sauna like the Finnmark barrel is the one to choose. Clearlight is the only infrared cabin we found that publishes EMF readings, at a premium price. LUMI is the mid-price infrared option, but it publishes little. If you want something smaller and cheaper, see our sauna blanket guide.
Frequently asked questions
Sauna blanket or infrared sauna cabin: which is better?
+
A cabin is closer to the setups used in infrared sauna trials, where people sit upright with their whole body in warm air. Blankets are cheaper and fold away but keep your head out and wrap you in plastic layers. If you have the space and budget, a cabin or a traditional sauna is the better choice.
Do I need an electrician for a home sauna?
+
Blankets and many one-person infrared cabins use a standard 13A plug, though high-wattage cabins may need a dedicated circuit. Traditional saunas with 6kW or larger heaters need a hardwired supply installed by a qualified electrician. Always check the wattage and installation instructions before buying.
Is an infrared or traditional sauna better?
+
For matching the research, a traditional sauna: the large Finnish studies linking regular use with heart health used hot, dry traditional saunas. Infrared cabins run cooler and many people find them easier, but their trials are small and mostly in heart failure patients.
How much does it cost to run a home sauna?
+
A 6kW traditional heater uses about 6kWh an hour plus warm-up time, so each session costs roughly the price of 6 to 9kWh of electricity. One-person infrared cabins of around 2kW cost about a third of that per hour.
