I love these sinks. We did have one problem with them, however. Although the base of one of them worked fine with the pop-up drain, the base of the other sink was probably 3” thick and the threads on the drain weren’t long enough. We ended up having to saw a substantial part of the underneath side of our vanity top of to account for the thickness of the sink. They’re very heavy, about 60# each. They go beautifully with our cedar vanity.
