Need some advice
I have attached a couple of pictures. When they fabricated my marble slab this wall was off square, hope that is correct term....what would you do? They are thinking of building it up with mud. Also if you will notice the bathtub, my faucets have to go right there at the edge....any comments I also have a handheld. This is a design flaw but it is too late now, have to figure it out.
