I am not even sure what the name of this would be but here it goes. Coming out of the wall going to the toilet is the copper fitting which a flex tube is connected to. My question is about the copper pipe coming out of the wall. The hole around it is much bigger than the actually circumference than the pipe itself. That is because the plumber put a plug on the end while the remodel is going on. Is there any type of cover other than just mud that a person can get to be decorative and cover the hole? Thanks.
