uneven bathroom floor

[brian c]

Got a bathroom to tile and the floor is uneven,when i say uneven i mean a belly in the middle.The floor is T&G WOODEN boards.Just want to know how you would deal with the floor to get it level before tiling.i have my thoughts but also open to other techniques.

movement,joints cracking 6mm ply used to put it down apparantly,as i say will let you know when im doing the job but was just open to suggestions as how to level off,cheers .

Could it be a joist thats thats bowed and pushing up with a supporting wall underneath

I'd remove floor tiles and see exactly whats causing the bowing, and if its just the boards tha have gone, up they come and ply.
