tiling a bathroom floor

[fluffyblond]

Hi we're going to tile our upstairs bathroom floor, our house is less than 5 years old, anyone know anything about preping the floor, I here you have to put a 18mm plywood base down to stop the spring in the floor, is there anything else we need to put down before we start, as 18mm of plywood and then the tile already create a step into the room.

IIRC that was about all I did when I tried my bathroom floor tiling.

Don't do what I did and use non-standard grout. I bought some sort of resin based one that needed a catalyst in the belief it would better seal out the wet; but it didn't look right, and proved impossible to easily wear down and redo.

I assume that you're going to use vinyl tiles. I tiled my kitchen floor a few years ago, and I used plywood as a base (following advice from the tile makers). That's all that you have to do, and you don't have to put anything else down. Place the nails 6 inches apart along the edges of the boards, and 9 inches apart in the middle. Placing nails at these positions helps to avoid any tendency for the boards to "spring". "... a step into the room": If it's a step up (or a step down) into the bahroom, you can put a carpet edging strip (made of metal, from carpet shops) down, in the doorway, to prevent people catching their toes on the edge of the tiles.

Apart from anything else Fluffy, using Ditra gives you a much smaller "step" into the room.......... even with the adhesive.
If you can't find a carpet strip the right thickness, then a hardwood threshold looks classy. If you're making a threshold, you can make it so that it "ramps up" to exactly the new finished floor height.

If it's vinyl, then you only need a 3mm hardboard underlay. If ceramic, then 18mm ply, or go for Ditra as suggested. Note that hardboard comes in more than one hardness - go for the hardest. The 'Oil tempered' type is best, but has become difficult to obtain.
