What is a "shower curtain"?

A shower curtain is a waterproof or water-resistant curtain that is used to keep water from splashing outside of a shower or bathtub. It is typically made of vinyl, polyester, or nylon and is hung from a rod or hooks above the shower or bathtub. Shower curtains come in a variety of sizes, colors, and designs, and can be easily changed to update the look of a bathroom. They are usually machine washable, making them easy to clean and maintain. Some shower curtains come with built-in liners, while others require a separate liner to be hung behind them to provide additional water protection. Shower curtains are an essential bathroom accessory that can add style and functionality to any bathroom.
