In the attched image the pipe stack is well out of plumb. Watched some
video clips and thinking this is the best way to go.
Any suggestions welcome.

From the top to the bottom of the boxed in area the plumb is out by 15mm.
It is my intention to cut the tiles at 213mm all the way down and have
an overhang at the bottom, then level with tile cement. OR
Would I be best to level first with `one coat` ? Before tiling round
the corner.
I also have some 9mm plaster board cut offs that I could possibly use to
take up the worst parts and then level out with cement.

Any other suggestions.
