why would it be damp under the lino?
I thought its waterproof.

If so then would floorbaords be better than OSB under the Lino
as any moisture could escape down the gaps between boards
(and cause mould where we can see it on the ceiling)

Erm, well, surely underneath your lino will be damp and a breeding ground
for mould. Main thing is to decide where the damp is getting in, also decide
if it can be vented, Bathroom steam goes everywhere of course so its not
uncommon to find what you describe in areas not often inspected.
More ventilation of the room can do a lot to help.

There's mould on the kitchen ceiling under the bath!
I'm thinking of pulling up the floorboards,
putting down 18mm OSB3 sloped to a point
with some kind of drain.
Then covering it with Lino or similar.
Much cheaper and quicker than a wetroom kit like

Advice please
