A shower curtain is a piece of fabric or plastic that hangs around a shower or bathtub to keep water from splashing onto the bathroom floor. It usually comes in various colors and patterns, allowing you to add a personal touch to your bathroom decor. Many shower curtains are designed to be water-resistant and can be easily cleaned. To use a shower curtain, it is typically hung on a rod with hooks, allowing it to be opened and closed as needed. Some people also use a shower liner behind the curtain for extra protection against water. Overall, a shower curtain is both functional and decorative, making it an essential bathroom item.
