How best to box in the soil pipe here

[samangin123]

Hi all,

I'm planning on boxing in the soil pipe that runs from behind the toilet underneath the floating cabinet, then I'll tile it with the blue wall tiles.

It's easy enough to build a simple rectangular box the whole way, but when it gets to the toilet, the edge isn't straight. As far as I can see I could either:

1) Just leave the little triangular gap and live with it, but don't think it would look great and would fill with dust quickly.
2) Make a tighter box that could finish directly behind the toilet (there's just about space) out of sight. The problem with this is, there's a few pipes in front of the soil pipe on the right hand-side where it meets the wall which also need to be boxed, so I'd have to adjust the shape on the right to include these.
3) White plastic trim scribed to the toilet to fill the gap - I've not scribed before so worried I couldn't pull this off well.
4) Scribe the box to the shape of the toilet and try to somehow get the tiles looking nice along a non-straight line at the end of the box.

Am I missing a simpler solution? Any advice would be really appreciated! Thanks

Close up showing the issue with option 2 - though i'm still inclined to think this is the best option. I'd just create an extension to the box coming towards the front of the cabinet, and have it meet the current wall tiling on the right.
