Perfect Matching Size and Seamless Integration: This 22x4 inch (length x height) side backsplash is specifically designed to match the Calacatta white quartz countertop, featuring the same 20mm (0.79-inch) thickness and consistent color/veining. It perfectly complements the main countertop and 4-inch high backsplash, creating a cohesive, seamless look for your bathroom vanity and eliminating gaps where water or debris can accumulate.
