Making sure that my levels are correct

    Hi

    I have gutted a property and am now making it habitable.

    Upstairs I have put down new flooring. With the chipboard, underlay and engineered flooring, the height of this floor lays at 300mm.

    In the bathroom, a lot of the old floorboards were damaged by woodworm. So I will replace them with a marine plywood.

    The standard size for this is 180mm. I know you can get it in 220mm.

    However once the adhesive and tiles go down in the bathroom, I expect the floor should raise up a bit.

    Not being a tiler, I don't know by how much. I am using 60x30 tiles from Topps Tiles, link attached.

    I may be over thinking a problem that doesn't exist. However any advice would be good.

    Cheers

    Mind your head on the door casings!:p:D

    The floor tiles for the bathroom will raise the level by about 15mm (150mm, if you prefer). But it does depend on the tile thickness. Normally about 10mm + 5 for adhesive.

    Make sure the joists are ok then!

    Also, when tiling on a wooden floor, which can move, (as opposed to a concrete floor), make sure you use a suitable adhesive and grout... something that can deal with flexing!

    I would spray the joists with Everbuild Lumberjack triple action wood treatment, excellent product,from competitors.

    Use a garden sprayer.:)

    That sounds a little thick - guess you mean 18 or 22mm

    Don't use Marine Ply if you are going to tile on it. Yes, it is water resistant and stable however there is a better alternative Hardie Flooring.

    It is available in both 19 and 22mm and the boards are 2400x500 with a T&G interlock. You can tile directly on them, they are stable and easy to fit.

    Yes I meant 18mm.

    Is James Hardie flooring easy to come by?

    The time I have needed it, no problem. I found I needed a couple of days notice to allow it to be moved between branches, but if you are planning well ahead - no problems.
