How to cover the gap at one side of bath? - Tile Advice

[momer79]

HI, we are redoing our bathroom and looking for a second opinion.

We are having an issue with the bathtub fitting snugly to the wall, as our wall seems to not be a 90 degree angle. There is 2cm gap at one side as shown on the picture with red line.

What are the options to cover the gap?

I do not like those gaps around the bath. How thick is the tile?
What does it look like on the other side of the tub?
