How do you begin a discussion about bidets? If you don’t know what they are or have never seen one in person, you might be a little surprised by the idea. They have been used in countries around the world for over three centuries as a way to clean up after going to the bathroom. In some European countries, you will see both bidets and toilets in hotels, although this is becoming rarer in recent years. Asian countries have adopted bidets as a way of keeping clean without the hassle and expense of toilet paper, and as a way to help the environment as well.
