Mosaic tile floors are having a renaissance. Of course, as many of you will point out, they never really left — lots of bathrooms, including the one in my New York studio, have floors like this that have been there for years. So these floors are not so much a trend as a classic that’s getting a (well deserved) moment in the spotlight. The bona fides of this particular kind of floor are many: they’re classic, they’re beautiful, they work with almost any style of bathroom.
