Porcelain tiles are denser, more durable, and less porous than ceramic tiles, making them suitable for high-traffic areas and outdoor use. They are also more resistant to moisture and wear. Ceramic tiles, while generally lighter and easier to cut, are better suited for indoor use, such as in bathrooms and kitchens. They offer a wide range of styles and are typically more affordable, but porcelain tiles tend to have a longer lifespan and greater resistance to damage.
