I bought two of these sinks for my master bathroom; they sit about three feet apart on the same vanity. As others have commented, the sizes vary slightly between individual sinks, but the difference is not at all noticeable when they are more than a few inches apart. I'm a very picky architect and if this was a problem I would be the first to notice. The finish of the sinks was decent for this price but not up to the five-start standards of the expensive brand names. One feature I like is that unlike some other low-rise vessels this one does NOT require an oversized cutout in the vanity, just the standard little drain hole.
