Traditional Saunas — Real Finnish Heat
A traditional sauna is a hot, dry timber room with a stove full of stones. You heat it to 70–90°C, throw water on the stones, and a brief wave of steam — löyly — moves through the room. That is the whole thing, and it has not needed improving in a thousand years.
It is not a steam room, which runs cool and wet. It is not an infrared cabin, which warms your body directly and leaves the air cold. A traditional sauna heats the room, and the room heats you.
What makes a sauna genuinely traditional
-
A stove with real stone capacity. 20 kg or more. Stones are the thermal mass that makes löyly soft rather than a scalding hiss — a heater with a token handful of rocks cannot do it.
-
Thick timber walls. 42 mm minimum, up to 70 mm solid logs. Thin panels reach temperature quickly and lose it just as fast.
-
Tiered benches in low-conductivity timber. Aspen and alder stay touchable at 90°C. Heat rises, so the upper bench is the hot seat and the lower one is where you start.
-
Controllable ventilation. Air needs to move through a sauna, not sit in it. Every cabin here has proper inlet and outlet grids.
-
Dry heat. 10–20% humidity between löyly, rising briefly when water goes on the stones.
Electric, wood-fired or gas
All three give you genuine traditional heat — the difference is how you get there.
-
Wood-fired is the original. No electricity at all, the crackle and smell of a real fire, and a slow build that many people prefer. It needs a flue and someone to tend it.
-
Electric is the convenient version. Set it, leave it, come back to a hot room. Needs a garden supply and an electrician.
-
Off-grid gas runs on a standard propane bottle — no cable, no trench, no consumer-unit work. It is the option that makes a sauna possible at the bottom of a garden with no power, and most retailers do not offer it.
Traditional sauna FAQs
What temperature should a traditional sauna be?
70–90°C is the normal range, measured at the upper bench. Finnish practice tends towards the higher end with brief löyly; a first-timer is usually more comfortable at 70–75°C on the lower bench. Humidity sits at 10–20% between throws.
What is löyly?
The Finnish word for the wave of steam that rises when water is thrown on hot stones — and, more loosely, for the quality of heat in a sauna. Good löyly is soft and enveloping; bad löyly is sharp and stinging, and usually means too few stones or too little of them being properly hot.
Traditional sauna or infrared — which should I choose?
They are different experiences. A traditional sauna heats the air to 70–90°C and gives you steam, sweat and the full ritual. Infrared warms your body directly at 45–60°C, so it is gentler, cheaper to run and quicker to warm up, but there is no steam and no löyly. If you want the thing people mean by "a sauna", it is traditional.
How long does a traditional sauna session last?
Typically 8–15 minutes in the heat, then a cold shower or plunge, then a proper rest — repeated two or three times. The rest between rounds matters as much as the heat.
Are these Finnish saunas?
They are built in the Finnish tradition, in Estonia — same Baltic timber, same construction, same heat. Estonia has one of the largest concentrations of sauna manufacturing in Europe and supplies across the Nordic region. We would rather tell you exactly where they are made than imply otherwise.
