The most wear-resistant type of tile is porcelain. Porcelain tiles are known for their exceptional durability and resistance to wear, making them ideal for high-traffic areas. This is due to their dense composition and low water absorption rate, which prevents them from chipping, cracking, or wearing down over time. According to the Porcelain Enamel Institute (PEI), porcelain tiles are rated on a scale from 0 to 5, with a rating of 5 indicating the highest level of wear resistance. Most porcelain tiles fall into the 3 to 5 category, making them suitable for any room in the home, including kitchens and bathrooms. In contrast, ceramic tiles, while also durable, have a higher water absorption rate and are rated lower on the PEI scale, typically between 1 and 3. This makes them less suitable for areas with heavy foot traffic or exposure to moisture.
