Hi,

 

Just about to purchase the sub floor for my new bathroom, I'll be using 18mm ply straight onto the joists which are at 350mm centres. I'll also be using 12mm tile backer board then tiles on top.

 

I was going to order the below ply from wickes but it's not got great reviews, does anyone have any experience with it? Or recommend another supplier or type?

Why plywood?

 

I only use T&G P5 22mm standard flooring material (chipboard). 
 

Then 6mm plywood over that, glued and screwed.
 

Then adhesive + tiles.

I’m creating a wetroom and need a finished size (before tiles) of 30mm and already got my 12mm tile backer boards so require 18mm for subfloor. A lot of people online recommended ply.
