Hello all

I'm looking to put in a WC in a right-angled-triangule shaped section of an old house bordering onto the dining room / family room and hence would like to sound proof it (for the sake of the user and the listeners!) as best as I can. The long side (hypotnuse) is solid already, the shortest side will be all door and the last side is the one that will be a stud wall that needs building and insulating.

I imagine there is an issue that whatever I do to insulate the stud wall, the noise will still travel through the door too so any suggestions there too please?

I don't want to go over the top, but I also don't want to hear everything that goes on in there...

Thanks

You will never make it sound proof.

To reduce noise a bit
Stud wall with interlocked studs (ie two sets of studs, every other stud slight Infront of next. That way oplaterboard on one side of wall is not connected to the plasterboard on other side of wall.
Lookup staggered stud wall

Sound absorbing insulation between plasterboard.

Heavy sound absorbing plasterboard, not normal plasterboard. If you have space doable up boards.

(Note that if a wet area for tiles best to use concrete board, which will not get damp and will still absorb noise due to its density).

Green glue ( I have never used)

Use a fire door not a normal door. If not practical, go for heaviest door you can use.

Hang lots of thick towels in bathroom to absorb noise. Put mat on floor (yuck).

Do not use an expensive silent fan, use a cheap noisy fan (not joking - does mask the noise).
