Domestic and hotel tap water supplies in Mallorca are safe to drink but, because the sources of water are usually in concentrations of limestone, the water is inclined to be hard, and may have a mineral taste. It may also be quite heavily chlorinated in some areas.

Yes, the tap water in Majorca is officially safe to drink and meets all European Union health and safety standards. Most of the island's water is sourced from reservoirs and deep aquifers, but because it is filtered through limestone, it is "hard" water with a high mineral content, particularly calcium. This gives the water a distinct, often slightly metallic or chlorinated taste that many tourists find unpalatable compared to the water back home. While it won't make you sick, many locals and visitors prefer to use a water filter jug or purchase inexpensive bottled water for drinking. In some very rural or older properties, the plumbing may not be as modern, so it is always worth checking with your host or hotel. Additionally, water is a scarce and precious resource on the island, so while it is safe for consumption, travelers are strongly encouraged to use it sparingly and avoid wastage during their stay in the Balearic Islands.
