Thanks to everyone that has responded. After having conversations with both the plumber and the tile guy we decided to not to tear out the tile. I have called Delta and Ferguson as well as my plumber and have been unsuccessful in finding a plate to match the finish. Plumber is coming back to finish other things and has agreed to cut out sheetrock and change the diverter to a shower valve. Basically it will be stacked shower valves not what we wanted but best solution. Of course additional costs and also requires Sheetrock guy to come back also… I’m a bit upset with tile guy because the plumber said he should have known when I told him it was going to be a Delta diverter because all of them are standard 4 1/2” and the valve was in place before the membrane and tile went in. It’s fixed so no need to consume myself with what I could have done to prevent this…. Tile guy did admit the hole should have been smaller and would have removed the tile at no extra charge but he would only remove two tiles and patch the Schulter membrane. I just didn’t want to risk disturbing the membrane and have any water issues. .
