Want the granite look for less? Swap out the enormous slab for smaller tiles. It's much cheaper, too. Although tiles can be purchased for as little as $7 per square foot, a slab countertop costs upwards of $60 per square foot.
You'll need a wet saw to cut the tiles to fit, but installation is the same as any other tiling project. Spread thin-set mortar on your surface, use spacers to separate the tiles, and grout in between.
