Hi all. I am moving from a three valve system to a single valve but the issue is the three valves arent side by side. I have a hot and cold tub valve and then three feet up a centered shower valve. The plumber at my house is saying in order to cover the holes created by removing the hot and cold tub turn ons/offs (valves) I need an adhesive goof plate. I cannot find anything. It is a 2 inch or so hole. What can I do here? Please and thank you.
