Which plumbing fixture is specifically designed to provide a space for personal washing?

The bidet is specifically designed for personal washing and hygiene. Unlike sinks, showers, and bathtubs, which are primarily used for cleaning different parts of the body or for bathing, a bidet is tailored to provide a strong focus on washing the genital and perineal areas. Typically found in bathrooms, bidets can include a faucet or a water nozzle that allows users to control the direction and flow of water for effective cleaning.

While showers and bathtubs offer a place for overall washing and can certainly aid in personal hygiene, their design and function are not as specialized as those of a bidet. Sinks are generally used for handwashing or to clean items and do not provide the same type of personal cleansing function that a bidet does. Thus, the bidet stands out as the fixture specifically intended for personal washing.
