The continuing saga of me and my broken plastic pipe and shower valve
lol...

So I am removing the sheetrock in pieces small enough that I can put them
back with minimal patchwork when I'm done - hopefully. As I open up the
wall behind the shower stall, I find that it is stuffed full of insulation.
Is this normal, typical, or even expected? Is there any reason to put
insulation in an interior wall simply because there is a shower stall on
the other side?


Probably for sound proofing.
