Posted By: djhMake sure you don't use ordinary plasterboard. Use moisture resistant or one of the special water-resistant boards.
How do you plan on finishing the surface? One option is to use XPS shower panels as both insulation and surface finish. The modern ones look good IMHO and are much better than products of yore.
FWIW I have clay paint on lime plaster on straw bales in my showers. But I do have MVHR which reduces the humidity. I painted Stormdry on those bits of wall that I thought were most likely to get splashes and it seems to work.
Posted By: daveking66Am I right in saying that water proof plasterboard wouldn’t be necessary if I go down the PIR insulated plasterboard route?

No, the point of moisture resistant plasterboard is that ordinary plasterboard can be ruined if it is exposed to a lot of moisture such as can be found in bathrooms. Waterproof boards such as Hardiebacker or Aquapanel are something else again - they are cement rather than plaster-based and are stronger. And then there are XPS insulated boards.

In my view it is better to stop moisture movement through or round insulation by using. A pour barriers on the warm side of the insulation, if the wall beyond the insulation is vapour open it will carry away moisture generally freeing the little there that remains safely away into the atmosphere and even when dew forms it will be on the very outside of the outer layer

Sorted! Thanks Ed 👍

I am puzzled
My understanding is that the house is a straw bale construction as such it should be very well insulated .

In general I’m leaning towards breathable systems as they seem to reduce the risks of interstitial condensation, but the Steico supplier (Ecomerchant) has advised that their boards should be covered with a layer of waterproof plasterboard if used in a bathroom - even though the wall will be dry (Ie with no adjacent shower)
