Toilet

A toilet is a sanitary fixture designed to collect and remove human waste while helping maintain hygiene. A common household toilet consists of a bowl, a seat, a flushing mechanism, and a connection to a drainage system. In many modern toilets, water fills the bowl and a tank or valve releases a controlled flow when the toilet is flushed.

The moving water carries waste through the drain, usually toward a sewer system or, in some locations, a septic system. The bowl is often made from glazed ceramic, a hard and relatively non-porous material that can be cleaned easily. Some toilets use a siphoning or jet-assisted flushing design to help move the contents through the drain. Models differ in their shape, flushing mechanism, water use, and installation.

Flushing works mainly through the movement of water and the design of the trapway, the curved passage that connects the bowl to the drainage pipe. When water enters the bowl rapidly, it creates a flow that carries waste through this passage. The trap also retains a small amount of water after each flush, forming a barrier that helps prevent unpleasant gases from the drainage system from entering the room.

Modern toilets are designed to use water efficiently while providing enough flow for effective removal. Proper maintenance includes regular cleaning and avoiding objects or materials that can block the drainage system. By combining water flow, gravity, sealed plumbing, and carefully shaped passages, the toilet performs a simple but important function in sanitation and everyday hygiene.
