As part of the bathroom refurb, I'm putting up a false studwork wall around a chimney breast - the chimney breast curves in on the top 1/3 and it needs to be flat for the shower to go against.
A lot will be tiled, but I will be left with an external corner plasterboard edge. What is the best way to finish this? I don't want to bother getting it skimmed (as I have done before when plasterboarding) as I doubt it's really cost effective for the small area we are talking about. And the corner is not in a very vulnerable area of the room.
