Thanks, John...It does need to be enlarged. The plastic plate was not used as a template, however, that doesn't change that there is nothing to screw the long plate screws into once it's enlarged.
With this particular valve body, there is a bracket with those tabs that attaches to the valve body. It wasn't attached during the installation as you can see in the picture. And that is where the problem lies.
This is a Delta valve. You can see the brackets that attach to the valve in the stock photo. There are no mounting screw holes on the valve body itself. That is what the bracket is for. Yes, there are screw holes in the trim with the long screws that would fit nicely into the holes of the bracket if the bracket was attached to the valve. The black bracket on the front of the valve is the shape the opening is supposed to be. At this point, it looks like I'll need to have someone attempt to put the bracket on the back of the valve without disrupting the pipes. Worse case would be to remove the valve and start over. Which is not that big of a deal, just frustrating. Thanks for your input!What brand/model is this valve? I don't see any mounting screw holes in the valve body. Are there screw holes in the trim? Maybe that large chrome "nut" screws on to hold the trim plate snug against the wall. If that's the case the wall "hole" doesn't need to be enlarged. UNLESS the trim plate is "bowl" shaped and hits the fiberglass.
especially on a new product. Thank you for "seeing" the problem. I can go through the wall behind the valve. That seems to be the only way. Thanks again.I've been doing this a long time but every once in a while even I have to READ THE INSTRUCTIONS
Some of the product designers have never installed the product
Can you see any way of installing the bracket without removing valve? Can you open the wall behind the valve? Much easier to repair DW than tub walls.
