Best Saunas in Finland

Löyly Helsinki

Hernesaarenranta 4, Helsinki • Design sauna • Year-round

Löyly is the sauna that put Helsinki on the world's design map. Designed by Avanto Architects, the building itself is a sculptural masterpiece of sustainably sourced heat-treated wood that cascades toward the Baltic Sea. Time Magazine named it one of the “100 Greatest Places in the World” — and for once, the hype is justified.

The sauna experience includes a wood-heated sauna and a smoke sauna (savusauna), both built to the highest Finnish standards. The smoke sauna is the real treasure here — the löyly is impossibly soft, the kind that makes you close your eyes and forget where you are. After heating up, you walk down to the Baltic Sea terrace and ease yourself into the water, which ranges from refreshing in summer to truly bracing in winter.

Löyly also has an excellent restaurant with a terrace that overlooks the harbor. My recommendation: book for an evening session, sauna first, then dinner as the sun sets. It is the most civilized evening Helsinki has to offer.

Allas Sea Pool

Katajanokanlaituri 2a, Helsinki • Outdoor pool & saunas • Year-round

Floating in the heart of Helsinki's harbor, Allas Sea Pool is where locals and visitors mix in the most democratic way possible. The concept is brilliantly simple: three outdoor pools (one filled with heated fresh water, two with filtered sea water) plus saunas, right in the center of the city with views of the cathedral and market square.

The saunas here are solid, with good löyly and enough space that you never feel cramped. But the real magic is the contrast experience — heating up in the sauna, then stepping out to swim in the Baltic Sea pool with the city skyline stretching out in front of you. In winter, the sea water pool drops to near-zero temperatures, making the sauna-to-swim cycle genuinely exhilarating. There is also a cafe, a terrace, and regular events. It is Helsinki at its most social.

Kotiharjun Sauna

Harjutorinkatu 1, Helsinki • Public sauna • Wood-heated since 1928

This is the real deal. Kotiharjun Sauna is the last remaining wood-heated public sauna in Helsinki, operating continuously since 1928. There is no design concept here, no Instagram-worthy architecture. What there is, is one of the finest wood-burning stoves in Finland, enormous old benches worn smooth by nearly a century of use, and the kind of authentic neighborhood atmosphere that money cannot buy.

The heat here is glorious — steady, deep, and wonderfully humid when you throw löyly. The crowd is a mix of long-time regulars from the Kallio neighborhood and sauna pilgrims from around the world. You pay at the desk, grab a bench, and become part of a tradition that has survived wars, recessions, and the rise and fall of public sauna culture in Finland. If you can only visit one sauna in Helsinki, many Finns (myself included) would tell you to make it this one.

Lonna Sauna

Lonna Island, Helsinki Archipelago • Island sauna • Summer season • SAUNA37 Award Winner

Taking a short ferry ride to a small island in the Helsinki archipelago to sit in a wood-heated sauna and then swim in the sea — this is the Finnish dream compressed into an afternoon. Lonna is a tiny island that was formerly a military site and has been transformed into a public park with a beautiful sauna and a restaurant.

The sauna itself won a SAUNA37 award, and rightfully so. It is intimate, beautifully built, and the contrast of the hot sauna with the archipelago sea is extraordinary. The ferry ride from the Market Square takes about 15 minutes and is part of the experience. Book ahead during peak summer — Lonna is well-known, and spots fill up.

Kulttuurisauna

Hakaniemenranta 17, Helsinki • Minimalist public sauna • Year-round

Where architecture meets sauna philosophy. Kulttuurisauna (Culture Sauna) was designed by artist Tuomas Toivonen and architect Nene Tsuboi as a public art project. The building is a stark, beautiful concrete and wood structure that sits right at the waterfront in Merihaka.

The approach here is deliberately stripped back: no talking above a whisper, no phones, pure focus on the sauna experience. The heat is excellent, the silence is meditative, and the post-sauna swim in the sea is mandatory. It is not the most social sauna experience in Helsinki, but for those who appreciate sauna as a contemplative practice, Kulttuurisauna is perfection.
