Don't ply it then. Use plasterboard - D&D with drywall addy then tile over that.

Plasterboard too thick,hence I am using ply,I don,t want it to be any thicker than 6mm.

6mm ply is nowhere near rigid enough to provide a stable substrate for tiling unless you want the tiles all over the floor in due course. If it's a depth issue get a spread in and get that bit plastered or do it yourself if you are comfortable with the task.

i agree. ply is a last resort method. using thin ply for tiles is very dodgy.
and marine ply is best/better in a bathroom.
expensive.

Hardibacker produce a 6mm board which is designed to overboard flooring. It would be quite suitable for what you require but I'd fit it with cement based tile adhesive to the wall (allow this to set at least overnight) then tile directly over it.

Hardibacker is a Tile backer board so perfectly suited or this application.

Get it a Travis Perkins or similar.

Don't use ply.

Thank you that,s great,the tile hardibacker looks just the thing.When you say cement tile adhesive,do you mean adhesive which is normally used for floors?

Hardiebacker really isn't suitable for D&D installation even with a polymer modified adhesive (you certainly should NOT use drywall addy) and as it seems your tolerances are very tight I can't see how else you would get it to line up perfectly with the plasterboard without an enormous amount of faffing about.

I still stand by my earlier advice - plaster it!

Cheers
