Currently I have a bathtub that was installed by developers when house was a new-build about 14 years ago. I’m planning to remove the tub. The entire bathroom floor is currently what looks like tongue and groove chipboard and the floor is tiled upto the bathtub.
I’ve purchased a 1700x800x25mm Mira Flight Safe stone resin cast tray to get the wet room look. I want to install the tray as low as possible so that by the time the floor is tiled then both levels are very similar height. When I remove the bathtub I will cut away the chipboard as I’ve been reading that it’s not a good base for laying the tray on. Once I remove the chip board one option I have is to lay ply to replace the chip board but this will bring the tray up again so it will get a higher level. Instead I’ve seen people screw timber battens along the side of the joists sitting lower with the thickness of the ply so that then panels of ply can be slot in which then essentially makes the floor level the same as the surface level of the joist. I’ve the seen people tank over it before laying a bed of sand and cement.
Anyone have any tips on this method? What thickness ply to use? Battens are often quite thin so when the ply sits on it, how do you screw it to the batten without the batten splitting?
A bit like what Roger Bisby has done in the start of the following video:
