Reducing sound in bathroom.

Sound deadening drywall

Sound system.

Sound deadening drywall and a solid core door.
Or just install a noisy fan!

Use staggered 2x4 studs on a 2x6 base plate if you can fit it. Pack the cavity with fiberglass batts. Insulation helps, sound deadening drywall helps, reducing the acoustical bridging is a BIG help. If you aren't messing with the other side of the bathroom walls then you could just tack a shim piece to the inside and add new studs on the inside only.

Anything is better than nothing, it amazes me that builders don't even think to at least offer insulation at bathroom walls (IMHO it should be standard in any "nice home"). Who wants to hear/be heard in the bathroom anyways?

That's key. If you hang sound deadening drywall from metal studs staggered between the existing wood studs it helps, since there is less mechanical transfer than wood studs.

Sill gasket, ripped to 1/1/2 stapled to the studs can help with the bridging issue.

If you any modify the wall to get staggered studs, I'd fill with sound batts (no vapor barrier) and use resilient channel on the walls. Then hang board.

Resilent channel on the walls...fairly cheap and effective solution!

Less fiber....

I remodeled my own bathroom last winter and insulated all the walls....I changed my floor from vinyl to tile and put in a solid core door....its probably louder than my old bath..its like a eco chamber in there....I think all the sound goes through the door..doesn't matter how much you insulate

I'd agree with just insulation doing little to nothing...the resilient channel is what separates the two layers of drywall from being a vibration microphone for each other (think of the kid's styrofoam cup & string phone...yarn transmits sound great...). The resilient channel separates the two surfaces, creating a sound barrier. Does it soundproof the room? absolutely not...but it sure does help!

Rockwool or the insulation from Menards made out of blue jeans are the only insulations I know of that help with sound. There's not any "one" thing that completely works. It's usually a combination of steps that work best. Adding resilient channel will help. Double the drywall. Use "green glue" from Menards between the two layers of drywall. All these things will do the trick.

Oh god, I've gotta follow a scrap blue jeans menards insulation post?

So....my experience with bathroom soundproofing is to make sure the hvac vents are closed or else everyone else in the building will hear what you two are doing in the bathroom......:innocent:

Almost forgot about these!!!!

Bathrooms are usually an echo chamber because of all the hard dense surfaces. Maybe some rugs or something similar will help deaden the echoes.

How about an elevator radio?

#2 post is the answer, Also cast iron pipes. Fiber glass batts have no real sound deadening efffect

What?

You're kidding, I hope. I've been in a lot of homes with batts in walls................big difference. One of many ways to deaden sound. probably the most common and least costly.

Where's Ted White when you need him?
