Place a useful decorative item, such as a trash can or container that holds items like toilet paper or hand towels, in front of the exposed pipes for a quick, easy fix. Match decorative items with others you are already using in the bathroom. For example, if you have a brushed chrome faucet and handle, use a brushed chrome trash can to cover the pipes beneath your sink.
Put a storage cabinet beneath the sink to cover up the piping. A storage cabinet is an excellent way to deal with a small bathroom or multiple people using a bathroom, as items like toothpaste, hand soap, body soap and shampoo tend to build up and make the bathroom look cluttered. Avoid picking a small storage cabinet that would protrude too far out past the front edge of the sink, to avoid bumping your legs or knees on it when brushing your teeth or washing your face.
Build a small, three-sided box from a cheap material like composite wood or pine and paint it the color of the wall. The box should only be large enough to cover the pipes, otherwise it may make your room feel cluttered. Make the box easy to move so you can access the pipes in case of damage. If you wish, you can put items that you don’t access on a daily basis, such as bathroom cleaning products and sponges, behind the box, next to the piping.
Paint the piping with specialty paint designed for metal the same or a similar color to your walls. Most hardware stores sell specialty paint that can be applied directly to clean metal piping for the purpose of making it less noticeable on the inside and outside of homes.
