Hi I have 3 bathroom floors currently Lino over ply substrate recommendations on what to use over the top of the ply prior to tiling I'm thinking of a ditra membrane !? Any other suggestions

I'am with the local on this - as I said earlier ' had to look twice to see what forum we were in' thought it was DIY!
Always amazes that people charge for a service that they are not skilled in.
