    Lavatory sink overflow codes
    Is there a buiding code that requires a lavatory undermount sink to have an overflow hole?

    Plumber is telling me that without this vanity overflow, it is code violation and therefore when time comes to sell my house, I need to get the sink replaced.

    I have never heard of a code violation for this application. You will have to have him prove to you that there a code.

    Whether kitchen undermount or bathroom undermount, they are making all kinds of sinks with no overflow hole, so how can it be a problem with code ?

    No, I would have to say no because I can't find anything that says there is a code for that.

    Edit: Loretta, enter 'undermount sinks' in Google and you will see sample sinks, kitchen or bathroom, with no overflow hole.

    Tickle nailed it.

    Ask your plumber if he has ever seen a vessel sink lavatory? They don't have overflows and more and more undermount bowls are being manufactured without a overflow.
