Essentially, they are shower sprays in a slightly smaller format designed for cleansing the anal and/or genital area with water after using the toilet. When permanently installed in the bathroom, these sprays are connected to the water supply or an outlet valve using a flexible hose. Bidet sprays are equipped with an integrated shut-off mechanism. Pressing a lever or button generates a gentle water stream. Many people find this method of cleansing more effective and hygienic than using toilet paper alone. In the case of portable bidets (also known as travel bidets or camping bidets), the principle of water cleansing is applied to a portable bidet spray.
