I'm currently having Rockwool Safe'n'Sound installed around my bathrooms to help with soundproofing. The crew doing the work has more general skills, and I'm not confident they've worked with Rockwool before. I've attached a picture of the installation progress. I also plan to provide some Green Glue Noiseproofing Sealant and acoustic putty pads for the electrical boxes. I'm concerned they might not know how to use these materials effectively, and if the Rockwool installation isn't done right, the soundproofing won't be effective. Before they close everything up with drywall, I could really use some feedback about whether this looks like a proper soundproofing job or if there's anything I should address now. Thanks!

It looks pretty good, but you might want to check around that S-shaped pipe. Sound can seep through any gaps, so stuffing Rockwool in those spaces would help. Most of the sound will get out through places like ducting or doors, though, so keep that in mind. If you have extra Rockwool, consider filling in the ceiling space too! Regarding the Green Glue, are you doubling the drywall or just applying it as a seal? There's a lot of debate on its effectiveness without extra layers of drywall, but it can definitely help.
What you have looks fine, but remember that soundproofing isn’t just about insulation—it’s about sealing gaps. If you leave any openings, sound can sneak through, rendering your efforts less effective. Think of it like trying to waterproof a room: if there’s a hole, it sort of defeats the purpose. You might want to address air gaps in the doors and be mindful of how you're handling ventilation, especially since bathrooms need good airflow.
Exactly! I want to keep the bathroom comfortable while adding privacy. Thanks for that analogy; it really puts things into perspective!
Rockwool should provide decent sound dampening, but don't expect miracles if you have pipes and vents in the way. If you really want to cut down on noise, think about swapping to a heavier wooden door instead of a hollow one. Just filling the wall won't completely soundproof the area, but it should muffle those awkward sounds when guests are around. Also, make sure to check for any missing insulation spots—like above the door—since that can make a difference too.
Good point about the door! I hadn't considered that. I’m just aiming for enough privacy for guests without going overboard.
Thanks for the tip! I'm also worried about that gap around the door—any way to seal it without trimming or replacing? I want to maximize the sound dampening without creating major changes to the bathroom.
