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!

Travisc, Mine is a 30" whitehaven and the 30" base. They come in two models... basically the same, but two different depths. The 9" is for new construction and the 6" is for an existing cabinet that you would cut the "draws" out of. My cabinet designer ordered the 30" base with the "blank" that works well with the 9". Kohlers web site has the specs. Because the sink is so heavy, the inside of the cabinet needs to be reinforced.... simple to do and their is a video explaining how. Love the sink, 30" for me is plenty big.

There are a few easy DIY places to check if you're so inclined. Turn the disposal off at the breaker first. -Pull the rubber flange out of the bottom of the sink. You should easily be able to see around most of the interior cavity to make sure nothing is down there. And FYI, this is a good thing to do periodically in the future, both to check the cavity and to rinse off crap that might be stuck to the bottom of the rubber flange. -The hose from your DW into your disposal should have a wire clampy thing over the rubber hose over the inlet part. Pull that off and see if there is any blockage at that point. Wait, have you even run your DW yet? If not, never mind. -Check the P trap; perhaps something is stuck down there? You know, nuts, bolts, rolls of PTFE tape... :) Anyway, it's at least something to check while you wait to get a plumbing appt, which probably won't be until after the long weekend, unfortunately!

I got my Shaw's (Rohl) sink online at a really good price from Home and Stone. I bought many things from them and they were just fantastic, even when there were problems (Manufacturer's fault, not theirs). It's beautiful, but we were just talking today about how it's a bit annoying that due to the fact that it's handmade, it doesn't slope perfectly to the drain and it takes a bit more effort to clear and clean it. They tell you up front that your sink cab must be templated onsite after you have the sink as there is up to 2% +/- variation since it's a handmade product. I am doing a very Victorian kitchen, so it's worth it to me. The Rohl sink is different from some others because it's fireclay, not enameled. Very different and far more durable.
