Depending on the type of floor tile, the grading of that tile, and the brand, tile can cost anywhere from $0.45 to $10 per square foot. The lowest cost type of tile is ceramic, and it typically costs around $2.50 per square foot, though it can cost less than $1.00 per square foot. Natural stone tile and porcelain tile generally fall within a similar range of each other: $5-$7 is the average per square foot. However, Grade One or artisan brand stone tile can cost far above the average or even the high-end ($10 per square foot). Imported Italian stone, for example, might cost more than $20-25 per square foot.
