We purchased a vessel sink that came with a faucet and the drain says "pop-up drain without over-flow". I don't like the faucet, so I purchased another one. However, it says "pop-up drain WITH over-flow".

Our sink sits on top of the counter and the plumbing is inside a cabinet. Does this drain difference matter in my case?

Srandall, it definitely matters. More than likely your vessel sink DOES NOT have an overflow hole on the front side of the sink like most typical lavatories. You will need the drain without the overflow because the drain assemblys are totally different and just suffice to say the drain with the overflow will not work on a vessel sink because of the way it's made.

If you like the new faucet you purchased you may use it provided you don't mind the little hole left open because, as malex points out, you don't have a bowl that will accommodate a pop up waste. You will have to purchase a drain that's designed for vessel sinks,(see image). Good luck, Tom

Thank you Malex and Speedball for the answers.

Can you provide a picture of the little hole that you are referring to? I wanted a grid drain. However, when we purchased one the grid is much smaller in diameter than the hole in the sink and the grid portion "sinks" into the hole and leaves an obvious unfinished look. Any suggestions to that?

My suggestion would be to nix the idea of a grid drain altogether -- There is too much surface area on a grid drain to adequately drain a sink without an overflow.

My personal preference for vessel sinks is a 'roll top' or 'flip top' drain, which will offer less surface area and allow better drainage.
