Hi everyone!
New to this most informative forum, and here goes for my firs post/question!
Done a little bit of research and it seems the informed opinion tha marine, or at least exterior grade ply of about 1/2 inch thick shoul be screwed down first to give a good base.
I am a little concerned that this and the thickness of tiles an adhesive would raise the level of the floor too much, (somewhere aroun an inch) such that it might be be significantly higher than th adjoining landing floor.
As the existing floorboards are in less than perfect condition, woul it make sense to remove them and replace the entire area to be tile with a slightly thicker plywood sheet screwed directly to the joists and then tile over that?
If so what thickness would be adequate? - It would make life easy if could use the same thickness as the existing floorboards - the fac that it would be a single sheet and screwed down instead of naile would mean that it ought to be stronger and more rigid than th existing floor, but would that be enough?
As the bath is already installed and I do not propose tiling underneat it I would be keeping the exising floorboards under the bath. It i also a fairly small bathroom so the area to cover is not huge.
Many thanks for your input
