Yes, all ICE (Intercity-Express) trains in Germany are equipped with multiple, high-quality restrooms in every carriage. As the flagship high-speed service of Deutsche Bahn, ICE trains are designed for long-distance comfort, and the restrooms are usually found near the entrance doors of each car. In 2026, the newest ICE 4 and ICE 3neo models feature spacious, barrier-free (accessible) restrooms with baby-changing tables. Unlike some regional trains, ICE restrooms are "vacuum-seal" systems similar to those on airplanes, making them functional even when the train is stopped at a station. While most are well-maintained, a peer-to-peer best practice for German rail travel is to check the digital display at the end of the aisle; it will show a green or red light to indicate if the nearest restroom is occupied or out of service, saving you from a long walk through the tilting train cars during high-speed travel.
