Shower Arm Plastered to Wall
I just moved into a new home and the shower head is too low for my family. We bought a new one that raises the shower head up by about a foot. Took off the wall plate and it looks like the old shower arm is plastered all the way around the hole. Basically it's the shower wall (tile) with a hole cut in it and then plaster filling up the hole and the shower arm sticking out.
Do I remove the plaster to get to the shower arm end that is inside the wall? How do I remove the plaster? Is this even possible without damaging the pipes?
Any advice would be most appreciated.
