Backsplash tiles are available in hundreds of materials.
The most popular ones are ceramic and porcelain. They have excellent resistance to grime, grease and water and are available in hundreds of colors, finishes and edge treatments. The best part is that there’s a wide range of price points to choose from.
Glass and metal are equally popular but pricier than the other two. Also, they tend to scratch easily and you have no option to sand it either.
Travertine tiles mimic the look of natural stone but need to be resealed frequently. Also, they are quite expensive.
Eventually, it’s based on personal preference and the look that you wish to achieve in the kitchen.
