Soundproofing an en suite toilet

[lfnfan]

Hi All

i'm looking for some advice on materials for soundproofing around an existing en suite toilet that already has some soundproofing in the stud wall it's made from.

The main problem is the sound coming from the wastewater from the toilet flush and cistern refilling that can be heard in the next door bedroom (bedroom 2), and the 'scoosh' of the waste water that can be heard directly below in the living room.

I am putting a cupboard on the adjoining wall in bedroom 2 and thought I could sandwich some sort of soundproofing material between the stud wall and the back of the cupboard. Would welcome suggestions.

To minimise the sound of the flush from the living room, I was thinking about adding - blowing? - some sort of material into the voids between the ceiling / floor joists, probably via the living room ceiling so I don't have to get someone to take up the carpet in the second bedroom. Would welcome any suggestions on materials too please.

Many thanks

Paul

Wrap nsulation around the waste pipe, double up plasterboard where possible

When we had a water tank in the loft and the wc was fed from that, the sound of the loft tank filling after a flush in the night was quite loud and went on for some time so perhaps our method which we still use even though we don’t have a tank any more might be of use to you. Don’t flush the toilet during the night! Perhaps you could consider using the main bathroom instead?

Thanks elite123.

Mottie - that's the approach we've been taking for the last ten years! Thought it might be time for a change....
