There are several types of ceramic tiles, each with its own unique characteristics: 1. Glazed ceramic tiles are coated with a glass-like surface that makes them water-resistant and easy to clean. 2. Unglazed ceramic tiles have a natural, matte finish that makes them slip-resistant and ideal for high-traffic areas. 3. Porcelain ceramic tiles are made from finer clay than traditional ceramic tiles, making them denser and more durable. 4. Terracotta ceramic tiles are made from natural clay and have a rustic, earthy appearance that is popular in Mediterranean-style homes.
