Public saunas in Finland are increasingly being treated as a new kind of happy hour, as urban “sauna worlds” mix heat, cold plunges and restaurant services to create social meeting points—especially for younger visitors. The trend, highlighted by Finland’s public broadcaster Yle in early March 2026, reflects a broader post-pandemic wellness boom that is reshaping how Finns—and an expanding international audience—use sauna spaces.
From Hickarö to Helsinki, sauna worlds are filling up
On a February Tuesday morning in Kokkola, the Hickarö sauna world is already busy. A morning sauna paired with breakfast draws in customers—particularly women—and the women’s side is often sold out on Tuesday and Thursday mornings, according to Yle’s reporting. Visitors move between the sauna and ice swimming through an opening in the ice (avanto, an ice hole used for winter swimming), turning what was once a private routine into a structured, bookable outing.
The appeal is partly practical—many venues combine saunas with cafés or bars—but it is also cultural. As Carita Harju, executive director of Sauna from Finland, told Yle, urban sauna culture is still relatively young in Finland even if sauna traditions are deeply rooted. The past decade has seen a wave of high-profile openings: Löyly in Helsinki, followed by venues such as Kuuma in Tampere, Viilu in Jyväskylä, and newer projects in other mid-sized cities.
Why young people treat public saunas like a weekend ritual
For many younger Finns, public saunas have become a place to meet friends in a setting that feels both relaxed and structured. In Yle’s description, people queue for weekend sessions in public saunas and sauna worlds, where the “happy hour” logic is less about alcohol and more about being together.
Two factors help explain the shift.
First, public sauna venues offer a low-pressure social space that sits somewhere between nightlife and exercise culture. Sauna visits can be paired with cold-water dips, short walks along the waterfront, or a meal—activities that fit the broader European trend toward wellness-oriented socialising.
Second, the format matches how many young adults plan their free time: bookable time slots, themed sessions, and “sauna rituals” (such as guided Aufguss ceremonies, where heat and scents are choreographed by a sauna master). These elements give a familiar structure to what is, in Finland, also a tradition associated with informality.
A Finnish tradition that is being reinterpreted in cities
The sauna is not new in Finland. Sauna culture in Finland is recognised on UNESCO’s Representative List of the Intangible Cultural Heritage of Humanity, and the UNESCO description underlines both the everyday nature of sauna and key concepts such as löyly (the steam/spirit released when water is thrown on hot stones).
What is new is the urban packaging. For decades, public saunas in Finnish cities declined as household saunas became more common, but the current boom is bringing shared sauna experiences back—often with contemporary architecture, waterfront locations, and hospitality services.
This shift also changes the social norms around sauna. In private settings, groups often share an implicit understanding of how much water to throw on the stones, when to speak, and how to move between the hot room and cooling down. In public settings—where strangers share benches—those norms have to be negotiated in real time.
Sauna etiquette is becoming the next big issue
As public sauna attendance grows, etiquette is emerging as a point of friction. Harju told Yle that behaviour in shared saunas “still leaves something to be desired”: some visitors speak loudly about matters that others may not want to hear in a sauna setting, and conversations can drift into overly personal topics.
In Finnish sauna culture, courtesy often means asking others how much steam they are comfortable with—how much löyly can be thrown—and keeping the shared space functional by refilling the water bucket (kiulu, a sauna water bucket) when it is empty.
Harju also floated the idea of introducing quiet sessions in public saunas. The proposal reflects a tension at the heart of the new “happy hour” sauna culture: saunas are becoming social hubs, but many people still come primarily to relax.
The international sauna boom, from Oslo to New York
Finland’s urban sauna boom is part of a wider international wave that accelerated during the pandemic years, when outdoor and semi-outdoor wellness activities became more attractive.
Yle points to rapid growth in the United Kingdom, but measurements vary depending on definitions. Some sources describe a sharp rise in the number of public sauna sites since 2023, while Yle’s figure suggests a much higher overall estimate. What is clear is that sauna is increasingly marketed abroad as a social and cultural experience, not only as heat therapy.
In Norway, the trend has become visible through the spread of floating saunas along the coastline. In Oslo, the Oslo Sauna Association (Oslo Badstuforening) operates multiple locations and promotes shared sessions throughout the day, turning the fjordside sauna into an all-weather urban activity.
Across the Atlantic, sauna has started to show up as a cultural event format. In February 2026, New York hosted its first sauna festival, described by organisers as a multi-day “village” of 17 saunas with guided sessions, performances and arts programming—an illustration of how sauna can be reframed as a lifestyle and community experience in cities that do not have a Nordic sauna tradition.
