Wood Panelling (T&G) plasterboard underneath yes or no?

[swilli88]

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?

I would say you will need extra batten supports to stop the T&G bending when pushed or warping with the damp.
Have you thought about MDF wainscoting panels instead of T&G much thinner have a google this sort of thing.

I did consider but same difference really. They are only 1 mm thinner than the t and g I have.

will have vertical battens fixed rigid to concrete wall and then horizontal battens for the panelling to fix to
