To tile a floor, first snap a line from the middle of the doorsill to the opposite wall. Mark the line into tile widths, leaving a VI 6-inch gap between tiles. At the edge mark off the last full tile, nail a room-width wooden batten 90 degrees to this line.
Nail a second batten 90 degrees to the first. Using floor tile adhesive, start tiling at the 3-foot width measurements square area within the batten corner. After pressing the tiles into place, insert 1/16-inch plastic spacers (available from your tile dealer) between them. Install the fractional tiles last.
After you are finished, grout.
