new tongue n groove - bathroom

[Pac]

hello again, after that last lot of great help i am back for another question if i may.

i have recently replaced the bathroom floor at my daughters. the floor was left for a week to adjust to room temperature and then isntalled with joist vises. they have been cramped very tightly so it will not shrink and leave gaps.

now i have tiled many floor but as this is the 1st time i have done it on new floorboards, i thought i would ask if there was anything i need to be aware of?

do i just ply sheet the floor as normal and screw it down or is there something else i need to do?

any special thickness of ply? or anything to be aware of?

thanks
