after getting 4 of my friends together to bring this 350 pound vanity up to a second story bathroom, having it installed, caulked, and ready to go, we discovered a factory defect. the porcelain in the drain was chipped. it leaks. after all that work i have a double vanity with one working sink. i called wayfair and they said that even though the broken sink is a separate piece that can be removed and replaced, they cannot send a replacement part. i would have to remove the vanity return it and have a new one installed. this would cost me thousands. the best they could do was a 25% refund. i feel sick to my stomach that i placed so much faith in this product, spent alot of money and time,  and i have a broken sink for the the indefinite future.
