If you want to understand the soul of Helsinki, start with a sauna. The Finnish capital offers everything from century-old bathhouses to sleek architectural marvels by the sea. Here are the best saunas in Helsinki—whether you’re seeking steam, style, or a barefoot dip in the Baltic.
Kotiharju Sauna – The Most Traditional Sauna in Helsinki
If you’re after the most authentic sauna in Helsinki, head straight to Kotiharju Sauna—no frills, no spa music, just steam, stories, and the solid hiss of water hitting hot stones. Tucked into the gritty-but-lovable Kallio district, Kotiharju has been doing its thing since 1928, making it one of the last proper public bathhouses left in the city.
Walking into Kotiharju is like stepping into a black-and-white photo. The scent of smoked wood clings to every surface, and the steam hangs thick in the air. Old-school Helsinki locals gather here to catch up on life, politics, and who’s getting married or divorced this week.
The sauna is split into separate men’s and women’s sections, where you’ll bathe the Finnish way—naked, of course. Cooling off happens out on the street, steam still rising from your skin as trams rattle by.
And if you’re lucky—or smart enough to book ahead—you might meet Kotiharju’s legendary washing lady, Merja Holopainen, who’ll scrub your back with professional flair and a no-nonsense attitude. For many, her washings awaken childhood memories of being bathed by a parent or grandparent. For Merja, the washing bench is almost sacred—a quiet, meditative space where the world slows down and the moment takes over.
Kotiharju isn’t trendy, and it doesn’t try to be. It’s honest, hot, and as Helsinki as it gets. So much so that even the Finnish Heritage Agency has stepped in to protect the interior as a piece of living cultural history.
Löyly – The Guggenheim of Finnish Saunas
“The Guggenheim of saunas”—that’s how the editor-in-chief of a Finnish trend magazine once described Löyly, and the comparison is spot on. Opened in 2016 and co-founded by actor Jasper Pääkkönen (yes, the one who made it to Hollywood), Löyly marked a turning point in the evolution of Finnish sauna design. Nothing quite like it had ever been built—here or anywhere. Architecturally striking and culturally bold, Löyly instantly became Helsinki’s newest landmark. In fact, the city protected it by zoning law just four years after its construction—a pace of preservation practically unheard of in Finland.
But Löyly isn’t just a pretty face. Located on the waterfront in Hernesaari, this sleek wooden structure offers one of the best sauna experiences in Helsinki—especially for first-timers or design lovers. Its name refers to the soft, rising steam created when water hits hot sauna stones, and the saunas here are heated traditionally with real wood. Among them is an authentic smoke sauna, a rare treat in an urban setting.
The atmosphere at Löyly is sophisticated yet relaxed. Swimsuits are required in the mixed-gender saunas, making it an accessible and comfortable option for tourists and families alike. After your sauna session, you can step straight into the Baltic Sea—year-round, if you’re brave—or unwind on the spacious terrace with a drink in hand, watching the ferries glide past.
Löyly’s commitment to sustainability extends beyond its architecture and energy use. The actor turned sauna entrepreneur Mr. Pääkkönen is a known advocate for fish conservation—so when you order the “Catch of the Day” from the restaurant menu, you can be sure it’s been responsibly sourced. It’s a rare place where design, tradition, and conscience come together on one stunning shoreline.
Löyly isn’t just one of the best saunas in Helsinki—it’s a symbol of how Finland reimagined an age-old tradition for the 21st century, without losing the soul of the steam.
Allas Pool – The Best Sauna with a View in Helsinki
If you like your saunas with a view—and maybe a latte afterward—Allas Pool is your spot. Just a few steps from Helsinki’s historic Market Square, this year-round urban spa is a favorite among visitors who want to try Finnish sauna culture without hiking into the woods or decoding locker room etiquette.
Allas serves up the full experience: modern saunas, warm outdoor pools, and one brisk seawater pool. While you’re cooling off, you can admire the view—ferries gliding by, tiny islands dotting the horizon, and Helsinki’s neoclassical skyline posing for your Instagram.
The saunas here are clean, stylish, and social—a great place to chat, unwind, or just stare blankly into the steam after a long museum day.
Sompasauna – The Most Bohemian Sauna in Helsinki
For the truly adventurous, Sompasauna offers a one-of-a-kind, grassroots sauna experience. Run entirely by volunteers and open 24/7 year-round, this is one of the most public—and most free—saunas in Helsinki. There’s no staff, no ticket booth, and no showers. Just a hot stove, a pile of firewood, the sea, and the sky. Anyone can walk in, chop wood, and fire up the heat.
You can bathe nude or wear a swimsuit—whatever feels natural. Just remember to bring your own towel, drinking water, and a padlock for the communal lockers. In summer, Sompasauna feels like a low-key beach festival: people chatting, guitars strumming, sausages sizzling, and the sun refusing to set. In winter, it turns into something beautifully surreal—a wooden hut glowing in the snow, with steam rising into the frozen night and fearless bathers diving into the inky sea through a hole in the ice.
It’s no wonder that Sompasauna has become a magnet for open-minded travelers. Some even call it the most international place in Helsinki. One thing’s for sure: it’s not for everyone—but if it’s for you, you’ll never forget it.
Kulttuurisauna – The Zen Master of Helsinki Saunas
Not all saunas are about small talk, sizzling heat, or cannonballing into the sea. Some are about silence. Reflection. Steam rising slowly in a room where nothing happens—and everything happens. That’s the world of Kulttuurisauna, a minimalist haven tucked along the Merihaka waterfront, just a short walk from the Helsinki city center.
Created by architect Tuomas Toivonen and artist Nene Tsuboi, Kulttuurisauna isn’t trying to be trendy—it’s trying to slow the world down. This place was built as a quiet rebellion against the idea of sauna as just another wellness product. Here, it’s a cultural ritual. A way of being.
The space is small, pared-down, and calm to its bones. Phones are off. Voices are hushed. The sauna is unisex and wood-heated, and the rhythm is meditative: warm up, cool down, take a dip in the sea, repeat. Robes are worn between the sauna and the dock, which adds to the atmosphere of gentle, respectful solitude.
If your idea of a perfect sauna involves silence, soft light, architectural purity, and maybe a philosophical thought or two, Kulttuurisauna might just be your personal temple.
Sipoonjoen Perinnesauna – Steam, Silence, and Sauna Rituals in the Forest
If you’re after something truly Finnish—like deep-forest silence, wood smoke, and a sauna that looks like it was built by forest elves with excellent craftsmanship—Sipoonjoen Perinnesauna might just be your happy place. Hidden in the village of Hindsby, on the edge of Sipoonkorpi National Park, this is not your average Friday-night sauna. It’s a full-on experience.
The smoke sauna here is the real deal: stone-built, low-lit, and filled with soft, aromatic steam that feels like a warm, ancient whisper. After a proper sweat, you can cool off in a cold plunge pool or ease into a hot tub, surrounded by towering trees and birdsong. It’s peaceful, elemental, and just the right amount of mysterious.
What sets Sipoonjoen Perinnesauna apart is its focus on sauna as ritual. On certain days, trained sauna guides lead traditional sauna ceremonies complete with birch whisking, herbal steam, and a good dose of Finnish folk healing vibes. You don’t have to believe in magic—but after one of these sessions, you might start to.
Public sessions are held on weekends (with separate times for men, women, and mixed groups), and you can also book the whole place privately if you’re after a quieter, slower sauna journey. It’s a little off the beaten track—but then again, that’s the whole point.
