I'm renovating my old kitchen and turning it into a downstairs shower and WC.

My neighbour has their kitchen on the other side of the wall, the wall being a red single brick wall- Victorian era.

I have pulled the ceiling down, added, acoustic insulation, 2 sheets of staggered plasterboard I now need to do something to the wall.

Max distance from the existing surface is approx 75mm.

I was thinking of installing a timber partition fixed floor to ceiling only, with a layer of mass vinyl stuck to the existing wall, air gap, partition with acoustic slab and 2 sheets of staggered plasterboard.

Anyone done anything similar?

All gaps will be filled and first layer of plasterboard taped and filled prior to second layer.

From what I have read you want to mount the plasterboard onto resilient stips which decouples the board from the wall. Then acoustic plasterboard which is extra dense. With 75mm you might want to pack the resilient stip off the wall and leave room for some high-density Rockwool like RS 60 as well

Similiar situation as you (victorian single brick and kitchens!). We built a timber wall fixed to the floor and ceiling only- not touching the wall. Filled it in with dense rockwool and put two layers of soundboard on top- cut the sound drastically for what was a relatively cheap and easy solution!

When investigating I also looked into 'proper' resiliant bars- metal bars that fit ontop of your timber frame to provide more decoupling between the plasterboard- though didn't use them myself. There's also 'real' soundproofing rubber material, but it was rather expensive so again I didn't actually try it.

As I've previously noted there's lots of advice on these pages:

I used one of the rubber products on the floor of a bedroom over a kitchen, no problem sleeping with dishwasher, washing machine or tumble dryer coming on off-peak.
