The answer to 'what is shower' is a plumbing fixture that is used to bathe or clean the body. Showers typically consist of a showerhead, which is mounted on the wall or ceiling, and a water supply that can be turned on and off to control the flow of water. Showers are a common feature in modern bathrooms and are often used as an alternative to bathtubs.
Showers can be designed in a variety of styles, from basic and functional to luxurious and spa-like. They can be equipped with features such as adjustable water pressure, temperature controls, and even built-in speakers or lighting. Showers can also be designed to be accessible for people with disabilities, with features like grab bars and seats.
