no rules on faucets..why dont you go to the store and put the faucet on a sink, and step back and lookatit planning your sink and valves is kinda a personal thing that no one can say your wrong or right...which opens the door for people like me that will put yellow tile and bright green paint togather, and think it looks good... step backand look at it,,listen to your inner self

I am not sure if it helps but don't look at the ADA version. It is for disability needs. I got the undercounter Kohler Caxton 17 by 14 and they fit just fine in my 21 deep vanities. HTH.

It depends on your faucet....so you need to have both the sink & the faucet picked out. In general, a faucet w/the handle on the side that goes front-to-back to turn water on/off will need more room behind it than a faucet w/a handle on top...but it could still be an issue for this one as well. Have you ordered your cabinets yet? If not, consider ordering a sink base that's 3" deeper than normal (i.e., 27"). If you've already ordered it (or have it), then look into pulling it forward 3". That's actually a nice look, btw. If I hadn't had the bay window behind my sink I would have done just that. If you cannot do any of the above, then you need to be very careful what sink & faucet you choose since they need to accommodate the window sill above it. Counters are usually 25-1/4" deep or so, but assume 25" Next, figure the sink will sit 2" or 3" back from there. How much does the window sill stick out? (1-1/2"?) 25" - 3" - 1.5" = 20.5" to work with. Now, look at your faucet specs and see what clearances you need. (Clearance usually includes width of faucet base & handle "swing".) 20.5" - clearance = maximum depth of sink. If you get the 105 and don't center the faucet, instead put it b/w the two sinks, then I don't think you'll have anything to worry about. We have the S405D and did that. The 205 may be more problematical since the bowls are equal sized with no "dip" in the rim, which means the faucet may have to be set further back. Have you considered that if you center the faucet over the 105 that it might not reach into the small bowl completely (again, depending on the faucet you're using)?

Sincere thinks to you all for the feedback. After doing more sink research, I found out that the new sink's cutout size had the smallest cutout size of all for the double-basin SS sinks I was looking at. I bit the bullet and found a handyman who came out to enlarge (dry cut with a shop vac) the granite. He was able to do it in <30 minutes., just by cutting 2 sides. It did cause a lot of dust, even with us prepping the kitchen area by removing everything from the counters, open food items, plus hanging plastic tarps on all sides of the kitchen to contain the dust to the area. The edge of the cabinet under the granite got slightly damaged but is still hidden, and the sink now sits flush to the countertop.
