It's great to have you join us, and I apologise for the delay in my reply.
Many thanks for sharing your project with us. Were there questions you had which we could assist you with? Do you know why the plasterboard is wet and whether an appropriate product suitable for wet-areas such as Gyprock CSR 2700 x 1200 x 13mm 3.24²m Aquachek Recessed Edge Plasterboard was used initially? I would suggest that if the plasterboard has become wet and saturated, it might need to be replaced. Alternatively, you could let it dry out completely and then coat it with paint suitable for bathrooms.
Please let us know if you have further questions or need help.
