Ceramic and porcelain are two popular materials for tile backsplashes, each with its unique characteristics. Ceramic tiles are made from clay and have a glaze on the surface, making them available in various colors and patterns. They are generally more affordable and suitable for most bathroom applications. On the other hand, porcelain tiles are denser and more durable due to their composition, making them highly resistant to moisture and stains. They are an excellent choice for bathrooms with high traffic and moisture levels. While both options can be used for bathroom backsplashes, the decision depends on the specific requirements, budget, and desired aesthetic of the project.
