Gap between trim and wall

[PETERHA]

Hi,
I have an issue here. My tiler has left a gap between the trim and the wall. No doubt the wall wasn’t true.

I have put some pics of this, but it’s hard to show well. The gap can be up to 6mm in places.

Two questions:
1 is this common practice? I would have thought that walls were generally not totally true. Wouldn’t the tiler correct this with new plasterboard or something?

2 is there anything I can do. Should I try and plaster this? Silicon would be uneven I think?

You could caulk it and paint it. would look fairly straight also did your tiler tile over paint?? But no a tiler isn’t going to fix slabs to straighten a wall. the studs could be off and it’s a lot more work and money to correct.

I would usually grout it and then it gets painted in with the wall, looks fine then.
