Intricate, custom backsplashes, which require tile to be cut into specific shapes, will always cost more than basic backsplash configurations.
David Portales, Spanish Tile Association: Any installation requiring multiple cuts or complicated on-site layout can affect cost. If you're not working with a designer, we would always suggest consulting a certified tile installer (visit the National Tile Contractors Association to find a certified, reliable installer) to help you decide if these design ideas are worth the installation cost.
Lori Kirk-Rolley, Tile Industry Professional: Typically, the layout of the tile design does impact the installation cost. Laying tile on a diagonal will result in more cuts, which, depending on the area of the country, could increase installation cost between 10 to 20 percent.
Verdict: Every expert said costs will rise when tile has to be cut. It's hard to predict how much costs will increase, because each backsplash project presents its own unique set of challenges. If you're placing tile in a diagonal fashion, or using multiple tile sizes and accent pieces, there's a decent chance some tile cutting will need to take place. And you can be sure these cuts will result in extra costs. Also, all our experts recommend hiring tile installers when it comes to these types of complicated backsplash installations.
