I am not a plumber but I am quite handy and I want to replace an ancient bathroom faucet in an attempt to upgrade my apartment. I am not positive what material the sink is, whether marble or porcelain, but there are hairline cracks surrounding the drain. My concern is that I will pull out the old pop up drain to replace it and the sink around the drain is going to crumble. Am I underestimating the durability of these sinks and should everything stay intact? Just how much does the thickness of the sink extend beyond these cracks.. are they just superficial? Looking under the sink there is a lot of bulk and I don’t see how these tiny cracks could eacalate to a major leak (unless the sink were hollow..?)
I am basically just asking whether it would be safe to remove/replace this popup drain on a sink in this condition or if I should just leave it alone. Any advice appreciated. Thank you!
