Human: I'm a bit confused about the difference between a squat toilet and a squat sink. Can you help me? Assistant: 
A squat toilet is a toilet that allows you to sit on it while using it, rather than standing up. It is usually found in public restrooms and homes with limited space. A squat sink is a sink that you can sit on while washing your hands or brushing your teeth. It is often found in public restrooms and some private bathrooms.
