Having a look in Wickes earlier at ply for the bathroom flooring, they do hardwood WBP at about £32 a sheet and they do structural spruce plywood for about £25 a sheet , what difference will it make in my application is the hardwood ply beter or not ???

If you are overboarding the existing floor Can you not use aquapanel ?

Sorry forgot to mention, its to replace the old soggy weetabix floor that used to be chipboard. as advised i was going to use 18mm ply but just wanted to confirm type and see if i could save a few quid , but if its going to be a false economy then would rather use the more expensive one.

Not well up on the structural spruce plywood, so if it was me I'd go for the WBP ply to be sure. The savings will be minimal, unless you have a massive bathroom!

I have always used 12mm WBP. Screw the existing boards securely to the joists and then screw ply every six inches to the chipboard.
If the chipboard has gone soggy, then it needs to be replaced with Green chipboard which is moisture resistant. The ply then needs to be screwed on top to avoid deflection.
It may be possible to use inch ply in place of the two layers but it won't save you any money.
Aquapanels or hardibacker are more expensive. Structural ply is for load bearing applications but I'm not sure if it is suitable for bathroom floors.
