What type of board and thickness is applied to a bathroom floor prior to laying tiles.?
Question:
Answers:
I think that it would be best to put down some marine plywood. It is a little more expensive, but will last in the long run.
You probably want concrete backerboard. You need to decide the thickness - is there an existing floor underneath? is the floor warped or uneven?
It's called concrete backer board. It comes in 2 different thickness, and if you ask at Lowe's, Home Depot, etc..they will tell you which will be best for your project:) It is the BEST thing to put down before tiling..it will keep your tiles from moving, grout cracks, etc, and is waterproof. It's not overly expensive either, and not too difficult to put down:)
Good Luck!!
I'd use Hardibacker. Lots of good info here:

And anticipating your next question this is a great resource for tiling.

Check out the reference library.
10mm minimum. When you lay you need to seal it before you tile.
It depends how firm the existing floor is, but at least 10mm ply, and ideally 12mm, SCREWED at 100mm centres, not nailed. No need to use tile backer unless you are putting electric underfloor heating in.
depends on the tile that you are using but if its ceramic you don't use wood you use hardybacker or a concrete board. If wood gets wet it swells and will pop all the tiles up.
some barmy answers here! Use 6mm pylwood screw it to the floor every 6-7inches.When you tile make sure you use the right products,primer, flexible adheves and grouts, most tile shops will supply and advise.
6mm if the boards are reasonably flat, 10mm if not, screw at 150mm centres using screws no longer than 20mm for 6mm ply and 25mm for 10mm ply or you might hit hidden pipes or cables. prime ply with a pva glue 1 part pva 2 parts water. use a flexible adhesive to lay tiles. good luck.
Hardy backer board works, but you should use cement board. They come in half and quarter inch thickness. Half is what you want, but if you want the floor lower, you can get away with quarter inch. The best way to set the cement board is use the cheap thin set with a very small trowel. A carpet glue trowel works best. Then stick some inch and a quarter galvanized roofing nails about 8 inches apart. You want to use mesh tape and thin set to cover the joints. If you are putting tile on the walls, you should take down the drywall and put up half inch cement board directly on the studs, with glue inbetween. Always use the galvanized nails, because the water from the thin set will rust them. There is glue you can use to set wall tile that is a lot easier to work with.
1/2 bc glued and screwed
You will require 3-6mm plywood screw down in to floor boards and check it is level. You will require flexible adhesive and grout to use with laying the tiles as this allows for movement of the wooden floor. It stops the tiles from popping up or cracking. Some adhesive do require the floor to be primed first always read the packet of adhesive before buying. Good luck
6mm ply fixed with ring necks every 150mm to existing floorboards, tiles laid on flexi adhesive and using flexi grout
Use ply wpb only, 1/2" will do, screw down and secure ensuring tight level joints.
Must be waterproof impregnated board.
