Hello everyone,
I'm in the process of renovating my apartment, and the new placement of the bedroom will be adjacent to the bathroom. The wall between these rooms is a typical interior wall; drywall + 45 stud + drywall.
I want to avoid disturbing noises from the plumbing and taps (which of course don't run through the wall in question, but can still be heard). Therefore, I wanted to ask you - what is the best material to fill the cavity between the drywall sheets? Regular insulation probably won't cut it. What do you think, should I go for high mass (like filling the cavity with drywall sheets) or some kind of sound-absorbing (preferably heavy) material?
All tips/thoughts are welcome!

Mineral wool is used for walls with very high sound requirements. Do you possibly have the option to widen the wall to 70 or 95 mm for thicker insulation? Double gypsum boards make a big difference. Seal around the new wall against walls, ceiling, and floor with special rubber-lined metal studs or latex sealant. Or has the wall already been built? Don't put in too much effort if the sound can bypass the wall through any beams, over or under the wall.
Ok, thanks Jonieboi for the detailed response!
It's probably halfway built you could say; the side facing the bathroom I can't touch, but I can open the drywall towards the bedroom and possibly widen it there / add mineral wool and extra drywall.
It's true that the sound can probably go "around" the wall in floor joists etc., so I will likely choose the simplest possible solution that still provides better sound insulation than just empty space between the drywall.
I think I have a clear idea of how to proceed in any case. Thanks.
