Don't know if there is such a thing available but we have just had a back to wall toilet fitted and the fitter cut a round hole for the waste to go into the back cabinet. Problem is that there is a one inch gap around the waste as the hole is a bit too large. Is there anything I can buy to cover the gap.
I was thinking something like a flat ring (white) which could fit into the hole around the waste. It would need an opening to be able to fit onto the waste.
Any suggestions would be gratefully appreciated.
