Rather irritated because I built cabinets with a 24 inch space thinking that would be more than enough for the 23 and 1316 advertised. When it arrived it did not fit and Im having to rebuild as the sink is a full half inch wider at 24 and 516 wide. Its also not square so the relief from the counter wont be the same on all sides. 2 instead of 1 because the sink looks quite good.
