The saunas are among the highlights. Some are built close to the water, offering striking harbor views. After heating up, many cool off with a quick dip in the cold pool nearby. This simple ritual blends city life with traditional Finnish wellness.
The modern design of the pools fits naturally with the surroundings. Wooden decks, glass walls and clean lines create a peaceful, open space. When evening lights reflect on the surface, the scene feels almost cinematic.
The seawater pool does not use harbor water. It contains filtered Baltic Sea water that is brought in from cleaner areas and purified using UV technology.
