Although they look similar and are made from clay, porcelain and ceramic tiles have different manufacturing processes that result in distinct performance attributes. Porcelain is fired at higher temperatures and pressure, making it denser, highly impervious to moisture, and suitable for outdoor sub-zero applications.

Because porcelain is denser and has a water absorption rate of less than 0.5%, it is highly frost-proof and suitable for outdoor patios, pool surrounds, and high-moisture bathrooms. Ceramic tiles, while still highly durable and easier to cut, are more porous and are best restricted to indoor wall and low-traffic floor installations.

When it comes to cost, ceramic tiles are generally more affordable and budget-friendly, making them popular for large kitchen backsplashes or bathroom walls. However, if you are looking for long-term durability in high-traffic hallways, commercial floors, or outdoor living spaces, investing in high-quality porcelain tiles will save you money on replacement and maintenance in the long run.
