Good afternoon all,

I have just laid WR chipboard down in the bathroom, i know i know should have used 25mm marine ply but to late now so i am going to lay 6mm ply down befor i fit UFH and tile.

Question is, is 6mm ply ok or should it be min 8mm?

ufh and travertine tiles.....

your going to need an uncoupling membrane ...ditra....

mate rip up that chipboard and replace with 18mm wbp then a 10mm insulation board...will be cheaper in the long run....

with stone tiles/ufh and "chipboard" its a failure waiting to happen imo.
