On-board toilet

An on-board toilet is like a potty in an airplane, train, or boat that you can use when you need to go to the bathroom. It is like having your own special bathroom that you can use while you travel. Instead of going to a public restroom or holding it in until you arrive at your destination, you can use the on-board toilet. This helps you stay comfortable and clean while you travel. The on-board toilet has a small tank where your waste goes, and it gets emptied and cleaned when you arrive at your destination.
