Any advice on what we can do to update these yellow stone bathroom countertops in two different bathrooms? Was planning to replace with white marble top veined with both beige and grey with square built in sink but looks like the yellow ones will be difficult to remove without damaging wall tiles. Any way to change the color of these stone countertops with dyes / bleaches / chemicals / epoxy / other? Could we also modernize with a rectangular raised sink? Plan to paint the cabinets (and walls) as they're too yellow as well. Also dislike the giant mirrors with electric outlet in the center :( Any advice on how to update these bathrooms without spending a fortune would be greatly appreciated!
