The wall around the countertop is called the backsplash, and is a good place to add a splash of flair to your kitchen. Its location makes it highly visible, and its relatively small size allows you to splurge a bit on materials. There are many options to decorate kitchen walls, but whatever you choose should be washable and not affected by heat, since it will be close to the stove and other food preparation areas.
Tile
Tile is the most popular kitchen wall decor, and with good reason. The sheer variety of tile types means there's something to fit nearly any style and budget, and because backsplashes are usually small, it can be installed fairly quickly. Use stone tile for a rustic look, brightly painted ceramic tile for a "cucina," or glass or metal tile for a contemporary feel. Look at different tile shapes --- square tiles are everywhere, so choose a round, oblong or octagonal tile to make your kitchen unique. Experiment with installing the tile horizontally, vertically or diagonally, or try a combination of the three if you're feeling adventurous. You may want to do a food-related mosaic.

If you have a bit of artistic skill, consider painting a fresco on your kitchen walls. You can use stencils and add embellishments yourself, or if your budget allows, hire an artist to paint a fully custom scene. Frescoes work very well with rustic Italian kitchens, but the painting can just as easily be done as a mural for a more arts and crafts feel. Be sure to use a semigloss or gloss paint, or a glossy sealer. These finishes offer maximum washability.
Pressed Tin
Pressed tin panels come in a variety of designs and finishes, and add an impressive touch to a rustic or retro kitchen. From charming to elegant, any style can be accommodated. Originating in the mid-1800s as an affordable imitation of expensive Victorian plasterwork, pressed tin has enjoyed a comeback. If you have a limited budget, most home improvement stores carry a selection of thermoset plastic panels that are nearly identical to the real thing, at a fraction of the price. They are very easy to install, requiring only adhesive and a pair of tin snips, that you may decide to do your ceiling to match.
Get Creative
Use your own imagination to create a unique kitchen wall. Try painting the area with magnetic paint, and sticking magnetized spice jars on the wall. You will never want a traditional spice rack again. Think about painting the
