Why a gas sauna?
No electrician needed
No 32A circuit, no Part P, no rewiring. It runs off a propane bottle — so it works the day it's delivered.
Heats in 15 minutes
The 8.1 kW heater brings the stones to full heat in 15–20 minutes, lit at the press of a button.
Goes anywhere
No mains power means the bottom of the garden, an off-grid plot, a field or a beach are all fair game.
A real sauna. The heat just arrives differently.
Sauna purists are right about one thing: löyly — that soft wave of steam off hot stones — is what makes a sauna a sauna. Here's the part most people don't realise. That heat comes from the mass of the stones and the water you throw on them, not from how the stones were warmed. A FinSteam gas heater holds over 20 kg of real sauna stones and brings them to full heat with a clean propane flame. You get the same rolling löyly and the same deep, enveloping heat — you just skip the smoke, the embers, the ash, and the hour spent feeding a fire.
Safe, simple & built in Finland
- The cylinder stays outside. A UK propane regulator + hose (included) runs to the heater — the gas bottle never sits inside with you.
- Oxygen Depletion System. If the flame goes out or oxygen drops, the gas shuts off automatically.
- Press-button ignition. Piezo ignition — no open flame to light, no kindling, no matches.
- CE-certified. FinSteam is the first LPG sauna heater in Europe certified under the EU Gas Appliance Regulation, and it's tested to −20°C.

A typical session uses roughly half a kilo to a kilo of propane. With a 47 kg propane bottle — the cheapest common refill at around £90 (about £1.90 a kilo) — that's roughly £1–£1.90 a session. A smaller 13 kg patio bottle is handier but works out dearer per session. Either way it's in the same ballpark as electric or wood. The real saving isn't the fuel — it's the £400–£1,200 you don't pay an electrician, and the weeks you don't spend waiting for one.

Gas sauna questions, answered
Is a gas sauna safe?
Yes. The cylinder sits outside, the heater has an Oxygen Depletion System that cuts the gas if the flame fails or oxygen drops, and it's CE-certified under the EU Gas Appliance Regulation.
Do I really not need an electrician?
Correct. There's no 32A circuit, no Part P work and no rewiring — it runs off a propane bottle and works on delivery day.
How much does it cost to run?
Roughly £1–£1.90 a session on a 47 kg propane bottle (~£90, the cheapest common refill) — comparable to electric or wood, without the install bill.
Can I use one in a smoke control area?
Yes. Gas produces no smoke, so it sidesteps the wood-burning restrictions that apply across most UK cities.
How long does it take to heat up?
15–20 minutes to full heat.
How long does a gas bottle last?
A 13 kg propane bottle gives roughly 15–20 sessions; a 47 kg bottle lasts most of a season. (Directional — varies with use.)
Where does the gas bottle go?
Always outside, connected through the wall with the UK regulator + hose we include.
