Tiled kitchen countertops
Not all tiled kitchen countertops are bad, but if the tiles look like they belong on the floor, then we’ve got a problem. And it’s twice as bad if they look like outdoor floor tiles, sort of like the ones in the picture below. They’re certainly not the ugliest thing in the world, but they definitely do make the kitchen look weird.
Stick to something neutral with a shiny finish. Matte tiles are nice, but you don’t need that sort of traction if cooking or eating on a kitchen island. Also, avoid using the same tiles on your kitchen countertops that you used to tile your kitchen’s walls.
