Minimalism and simple colors are always the best choices when changing a room. The white color may be easy to stain, but it looks so cool in an interior with a lot of small black details.
Now, instead of boring tiles on the wall, there is a matte pearl color. This is a great background for photos, paintings (yes, in the bathroom) colorful towels, and bathrobes. And an interesting idea is the initials above the towel hooks.
