    Hi there,

    not much to add beyond the question in the thread title other than context

    currently building out the stud framework for a new understairs WC (toilet and basin only). Tight for space on the width and trying to claw back every cm I can. We are planning tongue and groove panelling all the way around about a metre high and then the top half of the room a paintable skimcoat.

    question is if the wood panelling NEEDS plasterboard underneath it or can it be placed directly onto the studwork & battons underneath?

    Is there any advantage to having plasterboard under panelling?

    There are requirements under building regs relating to surface spread of flame, however due to the small size of the room this does not apply. There is a possibility that the stairs requires fire resistance if it is a protected stair and the WC is entered for another room rather than the stair hallway.

    the WC is entered directly from the hallway. does that change anything?

    is plasterboard typically behind paneling though or are battens directly onto the block wall enough to mount the panels onto? then i only put plasterboard above them?

    Sound proofing !

    @b4xtr do you mean that plasterboard offers sound better soundproofing than panelling? one side is a solid block between us and neighbours but the other is obviously a wall to the hallway.

    I am planing insulation in that hollow wall though for soundproofing improvement

    It's just that every thread about soundproofing on here generally recommends plasterboard ( it is a good sound blocker) but i suppose if there are say, gaps around the door, it might not be that important anyway

    i hear ya. makes sense to be fair, its dense material. I can put it on the full stud wall to hallway side possiby then avoid on the solid block wall to give me 12.5mm back to the width of the room. marginal difference but every little helps

    Dense slab fibreglass is a pretty good sound suppressor too, you could put it in the stud wall
