Tile is by far the most popular choice for the backsplash. Tiles come in alot of colors, tones, and textures, and are available in several materials. You could use tile that is related to your floor tiling, or pick something totally different. Glass and metal tiles may be used as borders or accessories, or scattered throughout stone or other tiling to develop patterns. You don't need to cover the entire backsplash with tiles, by the approach. You could just covers two-third with tiles, and leave the other third simple, painted wall surface area. Another option is to increase the countertop material up several inches, and then use tiles or something else for the remaining.Your Bathroom Needs Glass Tile30 Ways to Display Art and Photosbacksplash
