The best floor tile for flooring in the United States is generally porcelain tile. Porcelain tiles are highly durable, water-resistant, and less prone to cracking compared to ceramic tiles. They are also easier to clean and maintain, making them a popular choice for both residential and commercial spaces. According to the Tile Council of North America, porcelain tiles have a water absorption rate of less than 0.5%, which makes them suitable for all types of flooring applications, including outdoor use. Additionally, porcelain tiles are available in a wide variety of designs and colors, allowing for customization to suit any aesthetic preference.
