This could work in a tiny bathroom. Love the tiled floor/painted wall combo and the fact that the tiles in the shower match the wall colour but are different from the floor. The niche for storage works well for us too.
All of the apartment’s fixtures are by Kohler, including the kitchen sink and faucet as well as the Tea-for-Two bathtub, Vox square sink, and Catalan mirror in the bathroom. The Thassos marble subway tile is by Ann Sacks.
