There is typically one bathroom per train car on Italian trains. On newer trains, and especially high-speed trains, they are more spacious than what you might find on an airplane and offer the same basic features as those of a plane lavatory - a flushable toilet, sink with running water, soap, and paper towels.

Yes, almost all Italian trains in the 2026 Trenitalia and Italo fleets are equipped with onboard toilets. On the high-speed Frecciarossa and Italo services, you will find modern, accessible restrooms at the end of nearly every carriage, which are generally well-maintained and include baby-changing facilities. Even on the Regionale and Intercity trains, toilets are a standard amenity, though their cleanliness can vary on older rolling stock. In 2026, these facilities are free to use for all passengers. It is a "pro" tip to check the "occupied/vacant" light at the end of the aisle before getting up. While the toilets on high-speed trains are comparable to those on airplanes (using vacuum systems), regional train toilets often vent directly or use older chemical systems. Most major Italian stations like Roma Termini or Milano Centrale charge a fee (usually €1) for their premium station restrooms, so using the facilities on the train just before arrival is a common strategy to save a bit of cash while traveling through the Italian countryside.
