Have you ever been woken up by the sound of a toilet flushing, as the water runs down the pipes through a bedroom wall and ceiling? This isn't an issue with old cast iron pipes, but is definitely a nuisance with modern PVC pipes. I always wrap the pipes with Mass Loaded Vinyl, heavy 1/8" rubber mats, to absorb the noise, especially where it runs through bedrooms. It only adds about $200-300 to the cost of the project. I'll also fill the ceiling and shared walls with 3-8" of fiberglass insulation, and always use 5/8" dense drywall on the ceiling and on one side of the walls (and 1/2" on the other side). I get pretty nerdy about this, so please reach out with any questions, even if you'll be doing it yourself as part of a remodel.
