What is the difference between the two model numbers?
I think it’s the width.
Yeah, it’s a sizing difference. One is 33" and the other is 36". Sale has now been updated with this info.
I just purchased the 36" Dbl Bowl Sink, which was over 120$ cheaper than any place (Home Depot, Wayfair, Amazon)… well done!
What does the R20 mean on the item code?
The R20 refers to the corner radius of the sink. The 2014 models have a slightly larger rounded corners R20 (20 degree radius corner).
