Suggestions for best way to solve this problem please. Long edge of bath sits flush against wall, short edge is about 20mm gap down to 0mm. Build up the plaster? It's getting tanked and tiled
Skim the wall before tiling. You could chase the wall at the tight end if you didn't have the time or materials to skim in the corner. I know you know how to plaster though!
I hope you have batten fixed to the wall under the edges of the bath or plan to install it.
