I’ve had a 30” Shaw at a second home for 10 years and still love it but decided on the 33” Kohler Whitehaven for our new kitchen reno at home - it was such a price difference and looked so similar. I actually like it better! I especially like the slight slant of the bottom to the offset drain. Much easier to rinse scraps into the disposal. It’s still new but it does seems like the Kohler finish is easier to keep clean. We removed the Kohler logo (which was crooked anyway) so it’s just all white and looks great!

I've got the Kohler cast iron (and love it.) I'm sure if you dropped a glass in either the Kohler or the fireclay, the glass would likely break. I doubt there is an appreciable difference between the two. I haven't tried dropping a cast iron pan in my sink, but I did beat a Kohler display sink with a SS frying pan-no chips or scratches-though a non-enameled cast iron surface could possible scratch (just guessing here.)

@cpartist How do you like the DXV Hillside? Any pros/cons with it? Anyone else have one? We were originally considering the 36" Shaw farmhouse sink but the salesman said they all end up crazing over time. He said that Shaw makes their sinks they same way they did 100 years ago and it takes 3 days to dry. In those 3 days the sink settles and thats why the bottom can not consistently drain towards the drain (thus puddling) and that the settling enables the crazing to happen over time. He showed us several sinks like the Franke and Home Refinements Julien but those two were too modern for our kitchen (thinner walls). He said if you're going for a really worn in kitchen with lots of character in a 100 year old house, then those crazing spider webs on the Shaw won't matter. Our house is built in the 1930's with white inset shaker cabinets but I still don't want to look at cracks in my sink. The Hillside has almost the same dimensions and thicker walls like the Shaw. He said they poke a hole in the bottom front in the drying process and all the liquid fireclay pours out and leaves a shell of a sink. That leaves the sink sounding a bit more hollow when you knock on it, but also allows it to dry in one day so that it retains its shape. The water will drain toward the drain and the sizes don't vary like the Shaw (+/- 2%). I'm worried if something went wrong with the Shaw and we had to replace it, that it wouldn't fit exactly in the original cutout for the sink. I'm not too aware of the DXV brand though. Any good?

How will you feel about a substitute? Best case scenario, one month isn't that long. Worst case, well, three months is three months. And probably not as long in reality as it seems to you right now : ) . If it helps, we had one Currey & Co. light fixture for the dining room take about two months to ship from the US to Canada only to get lost and have to be reshipped (another two months or so), and the brass hardware for the kitchen and dining room be backordered for three months -- it's made in England, Lee Valley didn't have enough in stock and needed to re-order. But in both cases, while I knew I'd be happier to have a light fixture and hardware MUCH sooner, I didn't want those items to be "poor" substitutes. The light fixture makes the dining room, and the hardware (the same ones we have in our current house) is lovely. A teenage son's friend actually mentioned the other night how much he likes the hardware : ) . So for us it was worth the wait.
