cost per square feet to sand ceramic tile
Cost breakdown. 1  Ceramic tile: the backsplash 1 material averages $10-$15 per square foot, although it is possible to spend much more than that on premium ceramic backsplash 1 tiles. It is recommended to always purchase 10%-20% more extra tile in case of breakage. Total tile cost (including extra materials) for this project would be around $240. Mortar 2 adds another $75-$125, and sealer adds another $60-$100. Laborâ: most tile installers charge based on the size of the space, not the time it takes. Expect to add $10 per square foot in installation costs or a total of $160.
