I hate to differ with ARI001 but we do kitchen countertops with tiles almost exclusively...I mean by that, that we would install a $100 eight-foot length of Home Depot's best - but most of our customers have gone with our suggestions using Schluter Ditra and Rondec...even had a class on doing so and we had an 4-foot island from plywood-to-tiled in 20 minutes. OK someone had to cut the Ditra and mix the thinset but that was it from A to Z...stainless steel edging and all.
Had a customer this moring asking if we could tile her 20' of laminate, since she heard it can be done. Said nope, we only start from scratch. So we have the order to take out the existing, put down two sheets of 5/8" CDX, Ditra, modified thinset for below the Ditra, regular for above and standard tiles. The edging is finicky but looks great, altho' expensive (~$300).
The choices are limitless - that's the beauty. Granite tiles are about $5 each but porcelain is cheaper.
