I have been fond of cement tile from afar for a long while. I love its geometric simplicity and muted tones. The motifs aren't printed on the surface. Rather they are instrinsic to the cement material. Whether you call it Cuban tile, Moroccan tile, or Encaustic cement tile there are a few companies that have been the go to sources for this timeless building material for a few years: Granada Tile, Cement Tile Shop, and Kismet Tile. I'm sure you will recognize some of these patterns from your favorite retail shops and restaurants.
In the last few weeks I have noticed the use of cement tile exploding for modern bathrooms, kitchens, and outdoor patios on the interwebs. It is not cheap, but it is also a durable tile that packs a punch with its eyeful of sharp geometrics. Here some of my favorite lately.
Bathrooms are an obvious choice because their small square footage means you don't have to spend quite as much to get the effect you are after. These tiles look amazing with clean white subway tile too.
In general it offers Old World charm in a modern way. Win-win.
