I am tiling a first floor bathroom which has a plywood floor. I have a small floor area at the end of a shower tray which is 900 x 600 and I want to raise this by 50mm so that it is just higher than the tray. What would be the best material to use? Is there anything I shouldnt use? Intending to cover it with 6mm Hardie Backer and then tile.
