In 2026, asking for "regular" (tap) water in an Italian restaurant requires specific phrasing, as the default is almost always bottled water for which you will be charged. To request tap water, you should ask for "acqua del rubinetto" (AH-kwah del roo-bee-NET-toh). If the waiter asks "naturale o frizzante?" (still or sparkling), they are referring to bottled options; you should clarify by saying "Semplice acqua dal rubinetto, per favore" (Simple water from the tap, please). While it is safe to drink, many Italian restaurants are still culturally resistant to serving it for free, often citing the cost of washing the glass or the superior taste of bottled mineral water. To avoid confusion, you can also look for public water fountains known as "nasoni" in cities like Rome, which provide free, cold, high-quality drinking water to fill your own bottle. In 2026, sustainability trends have made asking for tap water slightly more common, but being polite and using the specific "rubinetto" term is still the key to getting what you want.
