Black is a very strong color for the bathroom. If you completely black the bathroom walls, you get a pretty moody place that looks modern but isn’t practical at all. The combination of black and white in bathroom design is much better as it also makes the room stylish and cozy at the same time.
Here’s another idea on how you can use black and dark gray tiles to decorate your bathroom without making it dark and creepy. This bathroom is 8.3 m² and has access to a small terrace that lets in natural light. It also visually expands the space. If you like dark ceramic tiles this idea could really come in handy for you.
