While the water in St. Barts (Saint Barthélemy) is generally treated and safe for showering and brushing your teeth, most locals and visitors prefer to drink bottled water. The island has no natural springs or rivers; all fresh water comes from a sophisticated desalination plant or from rainwater collection systems (cisterns). Because of this, the tap water can sometimes have a slightly "flat" or mineralized taste that many find unappealing. Furthermore, during peak tourist seasons, the demand on the desalination plant can be extreme, leading to variations in water pressure and quality. In most high-end villas and hotels, you will find a "water cooler" or plenty of bottled sparkling and still water provided. If you do choose to drink from the tap, it is unlikely to make you ill, but the local "gourmet" culture definitely leans toward bottled brands like Evian or Badoit.
