Steam & Oak

"Gas saunas can't do proper löyly" — we hear this a lot, and it's just not true.

Löyly is physics, not heater type: water hits hot stones, flashes to steam, and that's the deep heat you feel. Every sauna type — gas, wood-fired, electric — uses stones the same way. Our FinSteam heaters ship with a 40kg stone cage built in, so you get the same authentic löyly, just without the electrician or the wait.

We broke down the actual physics of what's happening when you throw water on the stones: https://steamandoak.co.uk/blogs/news/loyly-what-sauna-stones-do

Every time a sauna door opens, the room loses heat — obvious. What's not obvious is that not every heater recovers the same way.

Stone-based heaters (electric and wood) store heat in thermal mass. Open the door and the stones themselves cool, so the whole room has to re-warm before it's back up to temperature. Gas heaters just keep burning — they replace the lost hot air immediately.

Field data from one of our busiest gas-heated barrel saunas (35–55 hours a week, doors opening constantly) backs it up. We break down exactly what happens in the seconds after a door opens and why it matters more than heater output: https://steamandoak.co.uk/blogs/news/sauna-door-problem-heat-recovery

Your neighbour doesn't need to see smoke to be annoyed by it — they just need to smell it.

In May 2026, Brighton and Hove News reported a cluster of complaints about wood-sauna smoke drifting into next-door gardens, coating washing lines and making weekends unusable for the people next to you. It's becoming its own dispute category.

We still sell wood-fired saunas — plenty of people are in the right setting for it. But if your sauna sits close to a boundary, this is worth reading before you buy, not after: https://steamandoak.co.uk/blogs/news/wood-sauna-smoke-neighbour-complaints

Want a sauna without booking an electrician? You have exactly two options, and we have compared them properly.

An electric heater draws 25 to 32 amps, so it always needs its own circuit, an RCD and Part P sign-off. That is £800 to £1,500 and a one to two week wait before anything gets warm.

Gas needs a propane bottle outside and a hose. A portable setup needs no paperwork at all, and gas is exempt from smoke control rules, so it is legal in London or Manchester. Wood needs no wiring either, but it needs a chimney, an annual sweep, and a postcode outside a smoke control area, which rules out most towns.

The full comparison covers heat-up, running cost, maintenance and legality side by side.

We have ranked the sauna heaters actually sold in the UK, and the honest answer is that the best one depends on what you are trying to avoid.

Harvia, Huum and Sawo electrics from £400 to £2,000, but every one of them needs a dedicated circuit and Part P sign-off, typically £800 to £1,500 on top. Harvia's wood stoves win on ritual, then lose 28 to 43 percent of their heat up the chimney in independent lab tests and are generally not permitted in smoke control areas. FinSteam's Botnia 81 from £1,695 and Aurora 81 from £1,895 need no electrician and no chimney.

Running costs are roughly level across all three at £2 to £3 a session. You choose on install, legality and how much you like tending a fire.

Harvia Vega BC60 against the FinSteam Botnia 81. A budget 6kW electric heater versus an 8.1kW off-grid gas one.

On the shelf it is not a close contest. The electric is far cheaper to buy. Then you add the electrician and a dedicated circuit, and the installed gap narrows a long way.

We have set the two side by side on what each costs to get working, how they deliver heat into the room, and what they need from you to run. Same job, two completely different sets of requirements.

The bill nobody quotes you alongside the sauna.

An electric sauna heater needs its own dedicated circuit, and in most cases that is notifiable work under Part P. Once you are running armoured cable down a garden it commonly lands at £800 to £1,500, and more if the sauna is at the far end.

Our guide covers what actually drives that number, when you can avoid it, and the honest alternatives if a trench across the lawn is not happening.

An uncomfortable article for a company that sells wood-fired saunas to publish.

DEFRA's 2024 figures put domestic wood burning at 12 percent of UK PM2.5 emissions, and there is no level of PM2.5 that is considered safe. LPG produces 100 to 200 times lower particulates.

We still sell wood-fired. Plenty of people are in the right setting for it, and the ritual is genuinely part of the appeal. But if you are choosing a heat source and your sauna sits in a dense street, this is the data you should see before you decide, not after.

A wood-fired hot tub has no pump, no control panel and no electrician. Water moves round by convection alone: cold water sinks, passes through the stove, warms, rises. That cycle runs on its own for as long as the fire burns.

The honest trade-off is heat-up time. From cold it is 1.5 to 4 hours depending on volume, so it is a soak you plan rather than one you fall into at 10pm.

What you get back: roughly £3 to £8 of logs per session, and nothing at all when it sits idle. An electric spa costs about £40 to £80 a month to hold at temperature whether you use it or not. You also skip the £400 to £1,200 of running a dedicated supply down the garden.

If you use a tub every day, electric closes the gap. A few times a week, and wood wins comfortably.

Most of what goes wrong with a garden sauna goes wrong before it is switched on. A base that was not quite level. An access route nobody measured. An electrician booked for the wrong week, or not booked at all.

Our installation guide covers what actually has to happen: the base, the access, the build and the heater connection, with real UK costs. Construction from £500. Base £300 to £2,000 depending on type. Electrical supply £400 to £1,200 if you go electric.

One thing you can sort out today: measure the narrowest point of your access route, including the gate posts. That is where deliveries genuinely fail.
