I have installed Schluter DILEX EKE profiles around the perimeter of the Schluter shower tray and tiled the floor. The DILEX EKE serve the purpose of a movement joint at the junction of the shower wall and floor. In preparation for tiling the wall, I dry-fit a 24 x 48 tile on top of the DILEX EKE, and I note a ~1cm height gap between the tiled floor and the bottom of the wall tile; only about half the gap is filled by the EKE. Also, the 24 x 48 tile is convex at floor level, so the tile is sticking out from the wall about 0.5cm deep near the middle.
I am now concerned that the gap is quite large and the final result will be not be esthetically appealing. How would you go about compensating or correcting for the height and depth gaps to yield an esthetically good result?
