So the floor looks a bit tatty in the bathroom and is lined with part loft board, part ply and part chip board. Since I'm renewing the bathroom, I thought it maybe a good idea to pull everything out and refresh. The board appears to be 22.3mm thick.

Floor needs replacing.
Could sister joists to strengthen.

If you watch this you will see everything you need to do.

so its a good clip for education but doesnt really explain much esle than using pinewood planks for subflooring? I dont mind using that if gives me a solid floor. My idea was to use 15mm marine ply and 6mm cement board on top then your final covering??
