Cultured marble. Ask $50 and be willing to take $25.

Ha, I have the exact same thing! Was your home built in the early 1990s? I was figuring it'd be dumpster time for that thing but maybe there's someone out there who wants it..?

Mine was built in 2004. I was asking $40 for the 49" and $30 for the 36". 2 people interested passed because it's not new. You know, because people normally have brand new vanities with faucets already installed sitting in their garage.
