Any ideas on sound proofing a restroom...?

Question

As many people, I really don't like for anyone to hear me pooh. I know, I know it doesn't bother you. Well, ok, it's just me. How do you sound prood a bathroom?

Answer 1

Insulate the walls with Roxul, use resilient channel on the framework before drywalling, and use a "safe and sound" door at the entrance. These will all help cut the "noise" down a lot.

Answer 2

If you can , insulate the walls with roxul insulation, or if that is not feasible you can try this paint,http://www.hytechsales.com/prod150.html?OVRAW=soundproof%20paint&OVKEY=sound%20proof%20insulation&OVMTC=advanced&OVADID=3456691522&OVKWID=31222426022

Answer 3

Use a 2x6 bottom plate and stages the 2x4 studs inward and then out ward 16 on center, insulate and Sheetrock. This is how they do hotel walls.

Answer 4

Install foam insulation (the pink stuff) within the walls that you want insulated. Assuming you have 2x4 studs, you'll be able to fit in there 3.5" of foam, so get sheets of 2" and sheets of 1.5". Then the real fun begins!!

Oh BTW, if there's fiberglass in the walls already, take it out. Also, this is a rather medium/heavy job because it involves demolition and rebuilding of your walls. A lot of waste could be created and you might loose the usage of your bathroom in the process of this job.

You need to basically take down the walls. If they're plaster, knock it off the lathe and take down the lathe. If they're drywall, you *might* be able to find the screws (assuming you put them in and know generally where they are) and remove the walls that way, thus perhaps saving on material and time.

Anyway, when one side of the wall is out, you may have piping within the wall, you might not. There might be conduit in there too. If the house is old, there might be garbage or obsolete piping/conduit that was never removed w/ subsequent remodeling, thus adding to things to be removed and thrown away. Clean out the void spik-and-span of all debris. Now, you'll basically be putting the foam into the wall almost like you're putitng in a jig-saw puzzle, because you want to make the wall as solid and filled as possible. Going around the pipes will especially be fun.

Once it's all in, be sure that the drywall (especially if it's new d.w.) is moisture-rated for baths. If a wall that needed to be insulated was a wall w/ tile or durock backer, or if the side(s) has countertops, cabinets, vanities, mirrors on it, WHOA!! Your work would obviously increase BIG-time. Like I said, this is not a small/simple job. Maybe in cases like that you ought to remove the wall on the other side and fill it up from the opposite side. Maybe you ought to consider remodeling at this point. Filling in a wall is not something you could easily do because most baths don't have open walls to just knock down, fill, and re-wall. And who knows what's along the walls in the adjacent rooms. You'd then loose two rooms for this project.

So you put up new d.w., joint it up (tape and all), paint as necessary, and you ought to be set.

Blowing in cellulose doesn't help for sound insulation and you'd need to cut holes between all the studs. Sound proofing is not a simple task, but it can be done effectively depending on your logistics. Hope this helps.

Answer 5

Add insulation to the walls before you drywall.

Answer 6

unfortunately theres not much you can do on the plumbing side- i will say that spray foam will not resolve your issue for this will not insulate the noise as its being conducted through the water in the bowl not the toilet itself. spray foam can actually lift the toilet due to its expanding capabilities.

Answer 7

buy celotex ceiling tiles, glue them to the walls and ceiling,
or sound proofing panels
