Frequent Sink Stoppages

[EdwardL]

We remodeled our bathroom years ago. However, since that time our sink becomes stopped up very frequently. I do not shave at this sink and my wife is careful not to brush her hair there. Plumbers come in and snake it out and it gets better- never allowing a full rush of water - it seems less than my other sink - to go down but it does drain. Then it becomes stopped up again.
I understand venting may be an issue but plumbers have said if the shower drains easily – which it does – then venting would not be the problem. One said maybe the stopper is a bit thicker than usual and that "catches“ hair. Since it is a copper custom sink I do not want to replace the stopper and matching faucets because it does not seem probable.

Ideas anyone?

Since it is obviously not a standard lavatory sink, it is kind of hard to guess at what the problem may be. If you can post some pictures of the sink, the plumbing arrangement underneath, etc, perhaps we can see something that might help us help you.
