Tile labor varies a bit from area to area, but you can figure in the $7 a s/f range for basic labor , thin set, grout and 1/2 cement board , which is generally need when installing over the common wood sub floors. Tile isn t figured in this price since a plain , average or discontinued tile can go from $1 a s/f to a very nice tile in that size at 4$ a s/f Extras such as rip out/ disposal and any floor prep isn t included either.
