Worst purchase ever.  Absolutely do not purchase this one or any other knock off sink.  Firstly, the instructions for installation were in a language I don’t speak or read.  The plumbing parts are cheap and not typical standard plumbing parts.   Thing will match up to traditional plumbing.

My mistake was not inspecting it upon delivery since I wasn’t ready to install it until later in my project.  I went past the 30 days return window and now I’m stuck with a piece of junk.  I’ll either donate it or get rid of it.  Buyer beware!
