A lavatory is a room or space equipped for personal hygiene activities, primarily for using the toilet. It typically includes a toilet, a sink for handwashing, and sometimes additional features like a shower or bathtub. Lavatories are found in homes, public buildings, and various facilities, providing essential sanitation services. In many places, the term "lavatory" is often used interchangeably with bathroom or restroom. The design and amenities of a lavatory can vary widely, from simple and functional to luxurious and elaborate, depending on the location and intended use.
