If you’re considering black tiles for your bathroom, you may want to first consider how much sunlight your bathroom gets. Black absorbs heat more, so black tiles can become uncomfortably warm on a pretty sunny day if they’re being hit with tons of natural light. A window with large windows, a south-facing bathroom, or a home in a hot climate may not want to have black tile floors. However, if you’re still set on black tile floors, consider the material of the tiles. Ceramic and porcelain have high thermal conductivity, which means they retain heat longer than other materials.
Black tiles can make an interior look larger, but when not done right, black floor tiles can be overwhelming, making a room look smaller and darker. An all-black bathroom can look sleek and modern, but it can also look cave-like and monotonous. Natural light can help combat this by adding some brightness back into the space, allowing you to illuminate the bathroom. You can pair black tile floors with a lighter color on the walls. Or, if you want both black walls and floors, consider using lighter fixtures to help break up the darkness.
