Should the first row of tiles on a shower pan be angled or flush?
Our shower is being tiled with subway tile above a Kohler Purist shower receptor and the first row of tiles is not fully against the wall because, according to the tile installer, the lip of the receptor (cast iron pan) is behind those tiles. I know you are supposed to stay 5/8" off the lip of the receptor. He stayed a distance away, though I didn't measure. He used a tile spacer between the bottom of the first tile and the receptor lip, so I'm not sure what that measurement is. Anyway, is it correct that the first row of tiles is not perfectly vertical, but somehow angled? I'll try to go tomorrow and take a picture.
