There are several public toilets in Bruges (e.g. Station, Bargeplein, Lake of Love, Old Saint John site, ’t Zand Square, City halls, Gruuthuse Museum, Historium Brugge, Liberty of Bruges and Kuipersstraat). Some are accessible to the disabled, others offer baby-changing facilities. When locals require a toilet, they also often pop into a café, order something, and meanwhile make use of the facilities.
Here you can find an overview of all public toilets. All adapted public toilets for people with disabilities can be found here.
