A toilet bowl is a plumbing fixture used for the disposal of human waste. It is typically made of ceramic and is designed to hold water, which helps to flush waste away through a connected drainage system. The bowl is usually shaped to provide comfort and efficiency during use. Toilet bowls are part of a larger system that includes a toilet tank, which stores water for flushing, and a drainage pipe that carries waste to a sewage system or septic tank. They come in various styles and designs, catering to different preferences and bathroom layouts.
