I purchased my tiles on my own, prepped the shower with Kerdi, & installed the mosaic tiles on the shower floor. I realized that the tile saw I borrowed could not cut 24" tiles. I hired Ron to complete the job. He quickly noticed that the tints of 12" & 24" tiles were not the same. He had me return all the tiles and re-order all 24" at his discount. It was a very difficult install because the walls were not true. He did an excellent job.
