Unless you're in the market for a renovation or installation of a glass shower door, shower curtains are generally practical and they are certainly affordable. For a more streamlined solution, however, there's an alternative worth checking out: roll-up shower curtains offer sturdier performance, out-of-sight storage, and they can even make a small bathroom space seem bigger. Roll-up shower curtains are commonly made from waterproof PEVA and are designed to mount on the ceiling of your bathroom. These curtains generally span most of the width of bathtubs and feature generous drop-down coverage. One example of this kind of product is the Jakooz Ceiling Mounted Bathtub Curtain, which retails for $119.99 on Amazon and has a current 4.5-star rating.
