Charles Posted October 23, 2013 Report Share Posted October 23, 2013 New construction. National builder. All the vanity sinks have a 1-1/2 inch lip to the sink (four bathroom house). It certainly appears to this inspector that a lip this large is not correct. I have scoured the internet to look for a standard and cannot actually find a standard on the lip. I know that the vanity counter top fabricator should use the template provided my the basin/sink manufacturer. Opinions? Thanks in advance.

Jim Katen Posted October 23, 2013 Report Share Posted October 23, 2013 You could call it a concealed fouling surface. Mostly it's just stupid, though. Quote Link to comment Share on other sites More sharing options...
Jim Baird Posted October 24, 2013 Report Share Posted October 24, 2013 ...never thought about too much lip, except from certain individuals. There is no code requirement for an overflow go figure. Quote Link to comment Share on other sites More sharing options...
Jim Katen Posted October 24, 2013 Report Share Posted October 24, 2013 Both the IRC and the UPC prohibit "concealed fouling surfaces." I can see this being such a surface. Personally, I don't mention this in my reports when it's done on bathroom sinks. I often mention it when it's done at kitchen sinks, though. The instructions for the undermount sinks that I've seen say that the countertop is supposed to be cut slightly larger than the interior diameter of the sink, not smaller.
