I recently spoke to a friend who needed a change in her kitchen. She lives in a 700 square foot condo, and the kitchen is open concept. Her cupboards are a light beige which match the color of her walls, the appliances are silver and the counter is black granite with a hint of dark green in it. She had a designer come by to  add suggestions on how to improve the space. One of his recommendations was to add a new backsplash. He recommended green glass tile for her backsplash. Something so simple, yet such a dramatic change. Here are some places in Toronto that my friend went to when shopping for tiles:

And of course there are stores like Home Depot and Rona

Tip: If you live in a condo please check with condo rules and regulations. Your tradesman has to cut the tiles to be precise. This can be loud and your condo may have time restrictions.
