Have you removed your bathroom sink? Still have it? I would like to buy it from you. Ours is cracked and stained. I haven't gone the replacement stainless sink route yet. I figure if one is sitting around collecting dust I can take it off your hands.
If you don’t find one, cracked sinks are repairable with polyester resin and fiberglass. Mine had cracks and holes from the previous owner and now structurally stronger and looks close to as-new. Good luck.
