Very common in homes in the last 25yrs are acylic marble based vanities with the sink part of it .These vanities yellow and fade rather quickly. The bowls tend to have hairline cracks that develop.

For a fraction of replacement we can refinish with 2 options.

1. do entire vanity a single color or stone fleck
2. Give the vanity a two toned effect:bowl white with flat part a stoefleck. Identical to what you would buy at Lowes for a lot more than refinishing what exist.

It most often takes one trip to refinish bowl.next trip tape bowl off and stone fleck the top
