When you're showing a home for sale [1], one of the main priorities is to present a neutral but appealing space in which potential buyers can envision their own day-to-day lives. So even if you love bold color or a wallpaper print in your bathroom, tone it down for the sake of the sale. Painting walls a neutral shade or a pale, soothing blue or green will make the bathroom appear larger and give it a peaceful feeling. Paint the entry door, cabinetry and trim a crisp white for a clean look and renewed focus on the room's built-in details.
