The best type of floor tile for most residential and commercial applications is porcelain. Porcelain tiles are superior to ceramic tiles in several key aspects. Firstly, porcelain tiles are denser and more water-resistant, making them ideal for high-moisture areas such as bathrooms and kitchens. According to the Tile Council of North America, porcelain tiles have water absorption rates of less than 0.5%, which is significantly lower than ceramic tiles, which can have absorption rates as high as 7%. This low water absorption rate makes porcelain tiles less prone to cracking and warping due to moisture exposure.

Secondly, porcelain tiles are harder and more durable than ceramic tiles. They have a higher PEI (Porcelain Enamel Institute) rating, which measures the tile's resistance to abrasion. Porcelain tiles with a PEI rating of 5 or 6 are suitable for heavy traffic areas, while ceramic tiles typically have a lower rating. This durability ensures that porcelain tiles will maintain their appearance and integrity over time, even in high-traffic settings.

Additionally, porcelain tiles offer a wide range of design options, including various colors, patterns, and finishes. They can mimic the look of natural stone, wood, and other materials, providing a versatile and aesthetically pleasing option for any space. According to a study by the Tile Council of North America, porcelain tiles are the most popular tile choice among homeowners due to their combination of durability, design flexibility, and ease of maintenance.

In summary, porcelain tiles are the better choice for floor tile due to their superior water resistance, durability, and design options. Their low water absorption rate and high PEI rating make them suitable for a wide range of applications, while their design versatility allows for customization to fit any style preference.
