From dream to reality – The story of Höyry

Saunalaituri Höyry was born from a love of sauna bathing, open water swimming and community spirit. We wanted to create a place where everyone can pause for a moment, breathe deeply, and enjoy the good that nature and water do for you.

We noticed that the area near Uusikaupunki town centre lacked a place where you could go swimming — and especially to the sauna — easily, flexibly, and whenever the mood struck. We decided to make our dream real and build a sauna that offers an experience every single day of the year.

Planning for the project began back at the end of 2023, and we carefully scouted for a suitable location. Planning for the Pilssitie site got underway in late 2024, and the location turned out to be ideal — easy to reach on foot, by bike, by car, or even by boat in summer. In the design, it was important to us to combine functionality with atmosphere: we wanted a sauna with an sea view, and a pier that gives easy access for swimming.

Construction began in February 2025, and in March 2025 the first sauna-goers got to experience Höyry's atmosphere for themselves. The first phase of the project brought changing rooms, WC facilities, a 15-person electric sauna, a shower for a quick rinse in the steam room, and a swimming pier. This forms the operational foundation and allows for a quick start right in the middle of winter. As the project progresses, plans include expanding operations with a wood-heated sauna, shower facilities and additional changing rooms as demand grows. We're also investing in creating spaces suited to relaxing and cooling down.

Frequently asked questions about Saunalaituri Höyry

Where is Saunalaituri Höyry located and how do I get there?
Saunalaituri Höyry is located Janhuanniemi, right by the sea, at Pilssitie 23, Uusikaupunki.

You can easily reach us by car, motorcycle, bicycle or on foot. Turn from Laivarakentajantie into Märssytie, continue for about 120 metres, and turn left onto Pilssitie. Drive to the end of the road and you'll arrive directly at the shore. There's a free parking area next to the sauna.
How do I book a sauna or swimming session?
Saunalaituri Höyry is a self-service sauna that's ready and warm when your session begins. All public and private sessions are booked in advance through the booking service on our website.

Höyry is open every day of the year from 10:00–22:00. Sessions start every half hour and last one hour — you can book as many consecutive sessions as you like. Booking in advance means you know exactly when your session starts, and there's never any crowding, since the number of spots is limited.

Uusikaupunki is about an hour's drive from Turku and about two hours from Tampere. For companies and groups, we'll put together a package tailored to your needs on request.
Is Höyry a good stopping point for travellers, cyclists, motorcyclists or caravanners?
Absolutely. Höyry is easy to add to a coastal route, a cycling trip, a motorcycle tour, or a day off in Uusikaupunki. After a long day of driving or a cycling leg, warm steam and a refreshing swim in the sea really hit the spot.

A session needs to be booked in advance at booking system. The nearest campsite, Santtioranta Camping, is less than two kilometres away.

Uusikaupunki has enough to see to fill more than just a short visit. Places worth visiting include the Bonk Museum, the Uusikaupunki Automobile Museum, the Maritime Centre, Art House Pilvilinna, and the town's extensive Empire-style wooden house district.
What is the cold pool, and is it included in the price of a sauna session?
The dip pool is a one-person cold water pool. In the pool, you can sit shoulder-deep in cold water and enjoy a calm but effective cool-down right by the sea.

In summer, the dip pool offers an ice-hole-like cold experience. Combined with the outdoor shower, you can build your own contrast circuit: first warm steam, then a cold shower, and finally a dip in the pool. Use of the dip pool is included in the price of both public and private sessions.
What is Höyryn Hellin, and what can it be used for?
Höyryn Hellin is a covered, atmospheric extra space located right next to the sauna. It adds room around your sauna visit for meals, refreshments, socialising and small events.

Helli is a great fit for birthdays, bachelor/bachelorette parties, staff wellbeing evenings, client meetings, and get-togethers for families, groups of friends and associations. The space can be booked alongside a private sauna session. See the options in the Private Bookings section of the website, or ask for more information: info@saunalaiturihoyry.fi or tel. +35840 649 1261.

Janhuanniemi has been part of Uusikaupunki's history for centuries

As late as the early 1800s, the area was an uninhabited, rocky island, but by the late 1800s it had become a industrial area. In 1898, a sawmill was established on the site, making use of the sea's deep natural channel to transport raw materials and sawn timber. The sawmill got its power from a steam power plant, which produced electricity for the surrounding area as well as the sawmill.

Many also remember Janhuanniemi from the era when it was used by the Finnish Defence Forces. The area, closed off for a long time, began to open up again in the 2000s, and in recent decades it has grown into a seaside residential and recreational area.

Now, decades later, it's entering a new phase — this time as a place for wellbeing and relaxation close to nature. Saunalaituri Höyry brings new meaning to the area, combining traditional Finnish sauna culture with the sea and with history. Just like the power plant once did, Höyry once again brings energy to the people of the area and to visitors alike!

We want you to be able to enjoy the sauna experience exactly when it suits you best. That's why Höyry is open from morning to evening, almost every day of the year.
