Machining Marble SideSplash for Vanity
I have a Bath vanity which is surrounded by 3 walls, ie, set into alcove.
The vanity top is of course 49" wide Vanity Top, marble (marble-like) by RSI Home Products, available from Lowes. The left end of it, is stuck into a hole in wallboard (which existed when home was built. I want to fit a sidesplash, but they are meant to slip into the "Ogee'd" edge formed into the vanity top's edges.
Since this sideplash, and vanity top, looks like a cementous-type material, with only a marble gloss finish on the surface, is there a ay i can machine (cut, belt sand, grind) the bottom of the sidesplash to remove its matching "Ogee" relief and make it flat, and also reduce the height to match the vanity backsplash?
