One of the most popular colors for bathroom is grey. Bathrooms with grey color lend themselves to a wide range of design and decor choices. You can combine and create anything with grey bathrooms. There are several design ideas when it comes to grey bathrooms. For instance, spa bathrooms with grey colors. Grey is a color found in nature and is often associated with something cool and soothing, such as a silvery babbling brook. Recreate that soothing feeling by turning your grey bathroom into a relaxing spa. Fill a glass jar or cylinder full of smooth grey pebbles, and insert a few incense sticks into the rocks. Hang luxuriously large, soft fluffy grey towels on the walls, such as you’d find in a day spa. A natural rock fountain can sit on the vanity and add the gentle sound of water to the room.
