Thanks Nick, I will get the level out again, I was hoping for a miracle fix but I guess there is only the correct way to do things

12 by 4 inch Nick across a 3.5 metre span

That is an option that I didnt think of Russell, there are eaves cupboards and a stud wall covering the floorboards, if I can find the joist and its near enough to the edge I could cut the floorboards and re lay them

Just to add there will be very little foot fall on this area as its the end under the eaves and headroom there is 1.2 metres

Hi, I have a bathroom in a converted barn we bought which has limited headroom as its in the roof, I am in the process of converting it into a wetroom and in general have no issues troubling me apart from the floor from the middle of the floor to the edge falls away about 20mm in 1000mm. where the former for the shower is going is perfectly flat but the floor falls away from its edge, I know I need to raise the level to get a slight fall the other way, whats the best way to build up the floor as I`m on floorboards, Do I spend ages planing down a sheet of 18mm ply or can I build it up another way, Cheers All
