A Washlet is a type of advanced toilet seat that features a built-in bidet. It provides a gentle stream of water for personal cleansing after using the bathroom, promoting better hygiene compared to traditional toilet paper. Many models also include adjustable water temperature, pressure settings, and even air drying options. Originally developed by the Japanese company TOTO, Washlets have gained popularity worldwide for their comfort and cleanliness. They often come with additional features like heated seats, deodorizing functions, and remote controls, making them a modern upgrade to standard toilets.
