Subway tile is everywhere. I would say it's having a moment, except that subway tile never really went away. It's a classic. Of coure, most of the subway tile you see in kitchens and in bathrooms is white — like the tile you see on, well, the subway. But lately I've spotted a few instances of black subway tile, and I'm intrigued and I want to know more.
Black subway tile has many of the same advantages of plain old white subway tile —inexpensive, super versatile, classic shape — with a dramatic, unexpected feel. Use a little bit to liven up a kitchen or a bathroom, a lot for full-on glamour.
