So. I have managed to fit shower panels directly over tiles. My issue however is I had to cut the shower panels more than I had liked around where the water pipes come in due to the metal fixings that attached them to the wall. This now means when I screw the pipe collars back over the pipes, I’m some parts there is a 15.5-20mm gap. I don’t really want to try and bridge the gap just by siliconing it’s as would look shoddy. Any ideas? I have tried to find other chrome pipe collars that fit a 26mm pipe, but have a diameter of 80-100mm that are flat rather than cone shaped ,not higher than 10mm but am struggling but this would be ideal as would branch the gap and allow me to then silicone around edges.
