Why do you need so many screws? What would happen if you just had a few screws round the edges of the board for example? I love your channel by the way - I have learned so much.
The screws make certain that the plywood cannot flex or come loose, which would mean that the tiles would come loose or the grout would crack. When ever you do a job like this it is always better to over engineer, that way you are sure that nothing will go wrong! It took bloomin ages driving all those screws in LOL
I'm glad you like the channel, thanks for the comment ;-)
Your website states that for most tile types 12 mm over ply is enough. I have seen too many cracked tile floors. Floor boards differ in thickness, joist spacing differs (at least in the old houses I work in), boards may have shrunk so that tong & groove are no longer connected making the floor less rigid in one direction, and floor loads differ. I'd not recommend less than 18 mm in any case. Removing the boards and pouring a cement floor on lewis plates is a very secure alternative.
Yes, that was written by a guy that used to do lots of commercial tiling. 12mm does seem a bit thin but I am sure it is adequate for ceramics or porcelain. It's difficult getting decent quality ply in many towns and the stuff sold in the sheds is expensive and poor quality in many cases. There is one floor tiling video on youtube that uses 6mm ply :-0
It depends really. You could see the condition of the floor before it was ply lined. This floor used to have linoleum/vinyl down and it was not a problem for years, so unless you are having amtico or Karndean fitted hardboard should be fine.

Would you need WBP down if laying vinyl flooring in a bathroom, or would hardboard be good enough?
