Where are you guys buying these things? I found one here:
So I call my local Ace Hardware, and the guy says he shows an inventory of 91 of those...total...in the entire United States at any Ace Hardware-affiliated store. So then I call two more local plumbing supply stores (J&H Aicheson, Ferguson Enterprises). Ferguson doesn't have any, and J&H Aicheson was able to look it up, and said they've never sold one in over 30 years.
Clearly, not everyone is using these for their double vanity sinks. So what other code-legal options are there?
