Tilling A Bathroom Was Painting Bathroom And That's When I Noticed Crack In Sink- Now Do I Finish Painting Then Replace Sink Or

Was painting bathroom and that's when i noticed crack in sink- now do I finish painting then replace sink or - tilling a bathroom

First replace sinks? I have my own bathroom and empty their houses only. And I have to wait to get to payday for a new fountain. So thats a week and a bathroom with new wnna together only to be undone again, but I do not want to ruin the paint or help!
