Knocked bathrm/toilet into 1- Studwall insulation/sound prf?

Hi,

Can anyone offer me any advice please?

I am renovating a 50 year old ex council house and am in the process of removing a partition wall between a small toilet and small bathroom to make one big room on the 1st floor. (non-loadbearing).

I am then going to build a stud wall to block one of the doors up. My question is, do I need any sound proofing or insulation inside the stud wall and if there are building regulations, etc in regards to this? I am new to this so am a bit green.

Any advice appreciated,
Many thanks,
Rich

Building Regs, require sound insulation in a stud wall between a room containing a w/c & another habitable room (but not the room it serves if it’s an en-suite); if the door you’re blocking off is on a landing, they are not classed as habitable room so strictly speaking you don’t need sound insulation.

IMO, it’s worth doing though & the cost difference won’t be much; use 12.5mm Gyproc Wallboard 10 (not standard Wallboard) & some cavity wall insulation bats inside the void.

Richard,

Many thanks for your detailed answer, thats great. Yes, the door I'm blocking off, IS on the landing, but I will do what you suggest.

Thanks again,
Rich
