Bathroom floor advice
Anonymous user 23 February 2024 - 3.48 PM
I haven’t lifted the floor tiles yet but can see under the bath that the floor is chipboard that has been tiled onto. My question is can I just put 6mm no more ply on to the current chipboard or will these be too high as 6mm no more ply plus 9mm tiles? The chipboard will have to come up for the plumber anyway so am I best replacing it with say 15mm ply and then putting the 6mm no more ply on top. If the is the case will I need to leave a gap between the wall and ply and the same with the no more ply? Thanks in advance for advice.
Are you a tradesperson and able to answer this question?

Hi, first off work out how high the FFL (finished floor level) needs to be. If it is being re-tiled the best option here would be:
Remove existing chip board.
Noggin the joints if they aren’t already
Lay 9mm ply (lots of screws to new and existing floor joists/noggins
Ensure the floor is level, and then tile and seal.

Hi,
If the plumber is going to be lifting the floor anyway or at very least cutting sections out of it.
I would remove all of the old chipboard as that is not what you want on a bathroom floor and replace the whole lot with 18mm ply, backer board, decoupling membrane tile.

If you are taking the floor up and replacing it you don't need to line it. Use 18mm moisture resistant flooring glue all the joints and tile straight on top, using flexible adhesive and grout.
