You may think that a shower curtain is only good for keeping water off the floor, but you'd be wrong. Oh, so wrong. A shower curtain plays an important role in a bathroom's decor. They come in a wide range of colors and design, from plain vanilla to designer chic. You can choose one that complements your bathroom's look and feel. The nice thing about shower curtains is that you don't need power tools to install them. You can hang them on hooks with your bare hands from shower curtain rods.
