Sauna is not something Finns debate very often — we just go. But visitors arriving in Finland for the first time, or planning a summer cottage trip, always ask us the same thing: is a smoke sauna vs electric sauna really that different? The answer is yes. Genuinely, fundamentally yes. We’ve spent years in both, and we want to give you the honest comparison nobody bothers to write down.

This is not a “both are great, it depends!” answer. We’ll tell you exactly what each experience feels like, what the practical trade-offs are, and which one is right for your trip.

What is a smoke sauna, and why is it so special?

The ancient original

The smoke sauna — called savusauna in Finnish — is the oldest type of sauna in Finland. Before chimneys existed, it was simply the way saunas were built. You light a large wood fire inside a stone-and-wood structure, let it burn for four to six hours, then ventilate the space and enter once the temperature is right and the smoke has cleared.

There is no chimney. The smoke fills the room during heating, seeps into the dark wood walls, and the logs. By the time you go in, the smoke is gone — but the warmth radiates from every surface in a way that no other sauna type can replicate. The rocks stay hot for hours. The humidity is naturally balanced. The whole structure is alive with stored heat.

The sensory difference

If you’ve only ever been in an electric sauna, you may not realize what you’re missing. In a smoke sauna, the heat is round — it comes from all directions, not just from one heater below you. The steam you throw on the rocks (löyly) feels silkier, somehow more generous. The scent is subtle birch smoke layered with hot wood, and it stays on your skin. Some people find the first time in a smoke sauna almost emotional — it feels ancient in a way that is hard to describe.

UNESCO added Finnish sauna culture to its intangible cultural heritage list in 2020. The smoke sauna is the heart of that recognition.

What is an electric sauna — and where you’ll find them

The modern default

The electric sauna is exactly what it sounds like: a wood-panelled room with an electric stove (sähkökiuas) heating a pile of rocks. You turn it on, wait 30 to 45 minutes, and it’s ready. This is the sauna most Finns use every week. It’s in apartment buildings, hotels, gyms, and virtually every Finnish summer cottage built after 1970.

Modern electric saunas are excellent — don’t let anyone tell you otherwise. They reach high temperatures quickly, the löyly from a good electric stove is genuinely satisfying, and many newer electric stoves have large stone reservoirs that come close to replicating the soft heat of a wood-burning sauna. The difference is smaller than it was 20 years ago.

Wood-burning electric vs straight electric

A middle ground exists: wood-burning saunas with a proper chimney, common in Finnish lake cottages. These feel warmer and more authentic than electric, but nothing like a smoke sauna. The temperature climbs more slowly and unevenly, but the birchwood scent and the ritual of building a fire add real atmosphere. Worth knowing when you’re choosing a cottage rental.

For the purposes of this comparison, we’re treating electric as the “standard modern sauna” — which is the type most visitors will encounter in Finnish hotels, holiday parks, and urban saunas.

Smoke sauna vs electric sauna: the honest side-by-side

Here is the comparison as honestly as we can make it:

Our honest mistakes (and what we’ve learned from other people’s)

• Going in too hot, too fast. Both of us have done this. Ten minutes at 100°C with no experience is not impressive — it’s uncomfortable. Start at a lower bench, work your way up, and do shorter rounds until your body adjusts.
• Underestimating how a smoke sauna smells on your skin. The subtle smoke scent stays for an hour or two after leaving. We love it, but if you have evening plans, time your smoke sauna session earlier in the day.
• Throwing too much löyly at once. The first instinct is to ladle generously. The result is a blast of heat that drives everyone off the upper benches and is forgotten in two minutes. Small ladlefuls, one at a time, build a sustained steam that feels much better.
• Assuming the smoke sauna is hotter than electric. It is often cooler, actually. Smoke saunas usually run 70–85°C. The heat feels more intense because it radiates from all surfaces and the humidity is higher, not because the thermometer is higher.
• Skipping the cooling-off step. We have seen visitors sit on the bench for 30 minutes straight thinking that is the point. It is not. Go cool off. The contrast is the ritual.
• Not budgeting enough time for a smoke sauna. We once tried to fit a smoke sauna session into a 90-minute window. It did not go well. Block out the afternoon.

Frequently asked questions

A final word from Rovaniemi

We have a wood-burning sauna at our cottage, and we heat it every Friday. It is not a smoke sauna — it has a chimney — but the ritual is still the same: the fire, the wait, the heat, the lake, the cool night air, and the conversation that only happens in a sauna. Sauna is not a spa treatment in Finland. It is time.

If you visit Finland and someone invites you to their sauna, say yes. If you can get yourself to a smoke sauna even once on your trip, do it. And if you end up in a perfectly good electric sauna on your cottage porch, watching the Finnish summer night stretch on past midnight — know that this is exactly how most Finns experience it, and that it is quietly wonderful.
