I love my glossy black penny rounds that are grouted black. They cover the surface of the bathroom into the shower floor and up the full wall behind the vanity. They are unique and add an updated look to my mid-century modern home’s master bath without being too contemporary. They look great next to the simple white subway tiles that line the interior of the shower. I originally saw the black on black idea from the modwalls gallery where it was used as a kitchen backsplash. The black grout in the bathroom is awesome for easy clean up.
