I used vinyl floor tiles (12 X 12) for wall behind stove and microwave. They are very easy to keep clean. I did use extra contractors glue on the backs of them to make sure they wouldn't fall off with the heat and moisture.
Yes and if I took a picture of the wall border you would swear its the same backround as the border. I have also used vinyl flooring at the bottom half of my chair rail. With two big dogs coming in and out of the wet it sure makes for an easy cleanup.
