Yrjönkatu Swimming Hall

Yrjönkatu Swimming Hall, at Yrjönkatu 21 in the centre of Helsinki, Uusimaa, Finland, is the country's oldest public indoor pool, opened in 1928 and reopened in February 2026 after renovation. The setting is a classic municipal pool hall, run by the City of Helsinki, with a traditional atmosphere that has made it a landmark of Finnish public bathing culture. The traditional feature that sets it apart is its single-sex bathing: women and men use the hall on alternating days, and bathing is traditionally without swimwear. In the autumn season from 31 August 2026, women's days are Monday, Wednesday, Friday and Sunday, and men's days are Tuesday, Thursday and Saturday. The hall includes the main swimming pool and saunas on the first floor, and a locker is included with the ticket. There is no treatment menu or therapist service; the experience is swimming and sauna bathing in a historic civic building, and its reputation rests on its heritage, its low prices and its status as a living piece of Helsinki's public-bath tradition. A single ticket covers two hours and costs €6 (about $7 USD) for an adult, with a 10-visit card at €48 (about $55 USD). Weekday hours are roughly 06:30-20:00, with swimming ending at 20:30, though exact times should be checked on the hel.fi page. The hall is closed for summer from 24 May to 30 August. Tickets are bought at the entrance and no reservation is needed. Because the hall is single-sex on any given day, visitors should check the calendar before going so that the day matches their gender. The building is a short walk from Helsinki's central railway station and the main shopping streets, which makes it an easy and inexpensive addition to a city visit and a useful contrast to the commercial sauna venues on the waterfront.
