Not all saunas are the same. The room, the stove and the way heat is produced all change how a sauna feels. Whether you are building one or simply choosing where to sauna, knowing the types helps you pick the experience you want.
Here is a practical comparison of the most common sauna types.
Finnish wood-fired
The traditional wood-fired sauna is the archetype: a wood-lined room heated by a stove that burns real fire. It produces deep, enveloping heat and a satisfyingly earthy löyly. Wood-fired saunas take longer to reach temperature but hold it beautifully, and many people find the heat softer and more comfortable than any electric alternative.
Electric saunas
The electric sauna is the modern favourite for homes, apartments and gyms. A heater takes care of the stones and heat, turning on with a switch rather than a fire. It reaches temperature quickly, is clean and convenient, and still offers full löyly by pouring water over the stones. For most people building today, the electric sauna is the practical choice.
Smoke saunas
The savusauna (smoke sauna), the oldest Finnish form, has no chimney. The smoke fills the room, and once the fire has burned down and the smoke has been let out, the accumulated heat in the stones stays for a long, gentle session. The löyly is famously soft and the experience atmospheric — a real treat, usually shared at special times.
Portable and infrared
Infrared saunas use panels to warm the body directly rather than heating the air. They run at lower temperatures, heat up fast, and fit easily into a spare room — but they do not produce the classic steam-based löyly. Portable sauna tents are a low-cost entry into the ritual, though they are a compromise on the full Finnish experience.
Frequently asked questions
Which sauna type is most authentic?
The wood-fired and smoke saunas are the most traditional, with the smoke sauna offering the softest, most famous löyly. The electric sauna replaces the fire but keeps the essential ritual of heat and steam.
Is an electric sauna as good as wood-fired?
Faster and more convenient, and perfectly enjoyable — many people cannot tell the difference once it is hot. If authentic softness and ceremony matter most, wood-fired edges ahead.
Do infrared saunas give the same experience?
No. Infrared works at low air temperatures and produces no steam löyly, so it feels and works differently. Consider it a quiet warmth rather than a traditional sauna.
