Join between wall and ceiling

[scotties]

I have a small bathroom where plastering join between top of wall and ceiling is poor. Thinking about wheher can cover this up using some kind of coving. Is this a good idea?
Would need to be very minimalist given the room size, so any product suggestions much appreciated.

Thanks

You can get 90 mm polystyrene coving which is easy to fit and not too big. Just cut it to size and use decorators caulk to stick it up. Easy ... then just paint it.

What's wrong with the join?

The problem is basically poor quality of plastering after having a wall moved. Have not finished it well at top of wall, the join with ceiling is not a good sharp angle. Only became obvious when trying to paint it.
