In the course of your research, check out the laminates. Wilsonart makes some 15 1/2 inch tiles that look like stone, slate, etc. as well as the wood look that is popular. Formica also makes them. I've done several tile kitchens and it is an ambitious project. The laminates are definitely do-it-yourself and are as attractive as ceramic. You can find info at www.wilsonart. com.
