I personally find bathrooms a bit overwhelming when they are primarily one material, like being in a cave. Even a darker tile on the floor vs walls is an improvement. The blue vanity will help, but if the surface is the same marbled looking stuff as the walls, I'd find that not great.
Many on this page look too much, but the ones with darker floors end up less, I dunno, cave like?
