Allas Sea Pool

Opened in 2016 on Katajanokka quay next to the Market Square, Allas has a heated 25 m outdoor pool at 27 °C and a sea water pool that isn't heated, so its temperature follows the sea. There are five saunas from 70 to 90 °C, three of them floating on the pool deck with separate women's and men's rooms.

About Allas Sea Pool

The sea water pool is filled with water pumped in from further out to sea, where it's cleaner, then filtered and treated with UV light, and it uses no heating energy at all. It sits on the pool level beside the floating saunas, which look across to the Market Square. In the Corner Sauna you throw water on the stones yourself and look out on the Baltic, while the Panorama Sauna makes steam at the press of a button and faces the sandy beach area and the sea. At night the heated main pool is covered to save energy.
