There are several types of toilets commonly used today. The most common is the flush toilet, which uses water to remove waste. These toilets can be found in homes and public restrooms. Another type is the composting toilet, which breaks down waste using natural processes and is often used in areas without plumbing. Additionally, there are pit latrines, which are simple holes in the ground, and portable toilets, often seen at outdoor events. Bidets are also popular in some cultures, providing a water spray for cleaning after using the toilet. Each type serves different needs and environments.
