If you just want another similar vanity, I’d price out installing a new vanity first. Then consider the painting option. Painting is quite a bit of work, but if you like the countertop and the number of drawers, doors, and other features of the vanity, then painting might be the way to go. There are various paint products for this purpose on the market. Just make sure to read the directions carefully and follow the directions for preparation of the surface precisely. I suggest that you take a door or drawer with you to the paint store to get expert advice about the specific finish on your vanity.
