New floor in bathroom for tiling Page: 2

[tom_t]

Hi,

I'm replacing part of the floor in my bathroom in preparation for tiling. Current floor has got big "hill" in the middle probably due to not enough space left for expansion.

Current floor is 22mm thick chipboard and I'm planning on replacing with 12mm chipboard topped with 9mm ply screwed 25-30cm centres, is it gonna be ok?
I'm trying to keep new floor as thin as possible to avoid big step into the bathroom.

Is 5mm gap on the edges enough for expansion?

Is it OK to tile just part of the floor? I want to leave area underneath the bath untiled.

I'm planning to prime ply with BAL Prime APD and then use BAL Rapidset Flexible adhesive Grey/White can I use same combination for walls?

I'm planning on installing shower over bath, do I have to tank wall where showerhead is going to be?

Thanks in advance.

thanks for all your replies...

I'm going to use 18mm Ply (unless I find something thicker)
BAL BOND SBR + BAL RAPIDSET FLEXI + BAL FLEXI GROUT
I might be putting some noggins although bathroom is rather small (1.90x1.70m) and joists are 400mm centres so it should be ok.

I'm also planning to tile bath panel using 9mm Ply, question is how to mount it to keep access under the bath in case of emergency? Magnets/hinges/screws?

You could just make an access panel rather than the whole bath panel itself and affix that with magnets. Somewhere on here there was a thread about access panels, maybe worth a search mate.

tom if your using bal fast flex then you dont prime the plywood face you can prime the edges but not the face read instructions on the bag.
