There are so many options/directions you can take in tiles so if you have a look or feel or even better, a reference, take it with you when you visit your big local tile store.
BUT once you’ve decided on a tile and it’s a more “common” variety, go home and do some research. Shop around. Yes, you may have to travel a little further to grab a bargain but if you are like me and working to a budget of next-to-nothing, then a little time and effort can save you big bucks. I saved a few hundred dollars on my subway tiles just but shopping around.
