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?
