Hi
I am remodelling my bathroom and will shortly be laying new ceramic 45x45 cm floor tiles. The existing floor covering is vinyl (which i'll get rid of) and chipboard sheets on to the joists, as opposed to traditional (in my mind anyway) smaller floor boards.
lots of websites recommend putting an exterior grade plywood (9-18mm depending on who you ask) screwed down on top of floor boards then tile onto that.
Is this really necessary? as i imagine the larger chipboard sheets don't move much at all as opposed to skinnier floor boards.
i have two reasons to ask, one i'm hanging the basin tomorrow and need to know what height to work on, and two, i'd rather not have the hassle of putting the ply down and having to plane the door to fit the higher floor.
any advice would be appreciated.
thanks!
