Hi guys hopefully someone can help I’m tiling a splashback starting in center of wall which is below extractor fan.I set full tile there and put laser on on it but when I follow laser line at sink/window on return the lazer line is bout 2cm above tile(I set another tile there to check) will I just go off that point (full tile at sink ) ...and cut the tiles in below extractor.I just imagine it to look funny.thanks...
