uimahallien

Uimahallien is the genitive plural form of uimahalli in Finnish. It is used when referring to several indoor swimming halls or to describe something relating to them, for example uimahallien käyttö (the use of swimming halls) or uimahallien remontit (renovations of swimming halls).

An uimahalli is a facility that provides indoor swimming pools and related services. Typical features include one or more heated pools, changing rooms, showers, saunas or steam rooms, and sometimes a shallow children's pool, water slides, and gym spaces. Many uimahallit are designed for year‑round use and are open to the public, schools, clubs and private groups. They are commonly located in urban areas and operated by municipalities or public organizations.

Finland has a long tradition of municipal swimming facilities as part of public health and recreation policy. The development of uimahallit has focused on accessibility, safety and energy efficiency, with renovations often aimed at improving ventilation, water treatment, and toddler access. They also function as venues for swimming instruction, fitness classes, clubs, rehabilitative programs, and social activities.
