Sound reduction in bathroom wall

[font=verdana, geneva, lucida, "lucida grande", arial, helvetica, sans-serif]I'm aware that if rolls of floor insulation are installed below a timber floor that one also has to use a net to hold the roll up to the floor to allow continued air circulation.[/font]

[font=verdana, geneva, lucida, "lucida grande", arial, helvetica, sans-serif]I think there is a similar product roll which can be purchased but which reduces sound. I was considering installing this in the cavity of the wall beside where the bath/shower is.[/font]

[font=verdana, geneva, lucida, "lucida grande", arial, helvetica, sans-serif]Does some sort of similar net have to be installed to keep the roll affixed to one side of the cavity wall, and allow air circulation, or is it simply nailed against one of the walls meaning it won't block the entire cavity?[/font]

Is it a noisy shower that's bothering you or is it general sound proofing?

The cavity wall will be open during the installation of the bath/shower, so it seems like a good time to put some sound insulation in there to insulate any noise from the shower away from the bedroom immediately next door and adjoining the same wall.

Usually only a small part of the partition wall would be opened to move pipes. Usually not enough removed to bother with soundproofing. If you end up removing all the plasterboard from one side you could fill with rock wool and put up blue plasterboards. The blue boards are for soundproofing.
The term soundproofing can be misleading here as you wont totally soundproof but it can deaden the sound somewhat.

The wall is covered in 1930s timber tongue & groove wall pannelling, so this will all have to be removed since there will be a shower splashing water onto the wall, and it would probably rot fairly rapidly.

Therefore the wall will be "open" as a result of this.

I've been recommended Rockwool RWA45 Acoustic Insulation Slab, as apparently rolls of soundproofing material can have a tendency to sag.

What are blue plasterboards, and how do these differ from standard plasterboard?

They are designed for soundproofing
