Starting bathrom refit soon and have a few questions. I will be removing old plaster and either aqua paneling the shower area and plaster boarding the rest using dot/dab method. I have considered doing the whole bathroom in aqua panel but dont like the idea of loosing the space for the battens. Is it ok to tile (travertine)directly onto plaster board rather than having it skimmed and is there any alternative to using wooden battens to fix aqua panel that take up less space, I'm sure I read somewhere that someone used plaster board adhesive with screws added for strength but I can't find the post.
