I can cut marble for back and sidesplashes, so that’s not an issue.

It’s the back corner where it was taped that’s problematic. And in this particular instance I have both a piece of cultured marble that’s an exact color match in hand, and the tools to cut it close by.

So is the wall >90º or <90º? Not that I would think it matters. How thick in the marble? If you made a backsplash out of the marble, would it not cover the ½"? Or is the ½" gap including having a marble backsplash?

A vanity somewhat like the one pictured, except the corner isn't square (doesn't really matter how).



You install the vanity splitting the gap from the non-square corner across the two sides. Then you cut a backsplash that covers the gap between the wall and vanity on both sides similar to what is pictured below. I would think that the thickness of the marble should be enough to cover the gap, especially if the gap is evenly distributed across both sides.



Or is the issue the vertical edge of the vanity where there would be a gap (assuming corner is >90º). If so, then possibly some cove moulding there. The only thing that I'm not sure of is the top corner of the vanity. It's hard to know where the problems are without photos.
