You could go with either size, it all depends on what you like best, there is no right or wrong. I have an 18" wide linen cabinet going on the left side and then 48" of counter top. Yes, it's the 21" standard depth. I measured it and there is 3" in front of sink (of counter) and 4" from sink back to the coved backsplash. I had my sink undermounted in a corian counter top. I like the integral sinks but the white corian always looks dull and dirty to me so I wanted a china sink. Don't forget to consider your faucets if you go w/ the larger sink since there's not alot of room between the backsplash and sink edge. I got a 4" mini spread and there's plenty of room to clean around them. If you go w/ the smaller sink, I'm sure it look fine, too. I almost went w/ the Ladena which is rectangular, check that out also.

Thank you both so much!! Those faucets look great - and probably confirm my suspicion... that all my stress about this is unnecessary... pps7 - what is your faucet? Also, do you have the same faucet on your prep sink? I'll have a 15x15 prep sink a similar distance away from the main sink and wasn't sure if I should go with the same faucet or a smaller version. circuspeanut - do you have a prep sink? If so, what did you do for your prep faucet? Also, are the little buttons next to your faucet airswitches for your disposal? I hadn't heard of these until recently and I'll have three windows in front of our sink so they may be a good option for us. What do you think of them? Any problems? Thanks!!

Thank you for all the comments, I still love hearing from everyone and their opinions. I still am changing my mind everyday about that sink, it’s very useful... as far as everyones comments of it not being big enough (how big are your sinks?!... haha) btw the middle sink isn’t for washing, it is food disposal :) I use the left sink for washing and the right sink for rinsing. I do have some good news I just discovered 10 minutes ago (seriously)...it looks like the upper cabinets are original! Which makes me so happy because they are my favorite! Woohoo,... the doors are newer, I’m guessing to match the newer bottom cabinets. How easy is is it to move the dishwasher over to make room for this sink/or future vintage sink? It bothers me that it’s off center. And since the bottoms aren’t original so I don't mind moving things around. Thank you again to everyone so far !

Stacy, I have the Akurum line which had the split top drawer standard. It can be done by mounting a divider to attach the rails to. That is how I do the individual trash pullouts under the sink (see the under sink photo I posted earlier) . I dont necessarily think split drawers are an advantage because you lose about 3 1/2” storage. I like the off-white Bodbyn. It’s not yellow in my kitchen which does have warm lighting @ 3000K and lots of wood which causes it to photograph with a yellowish cast. Look back at my daughter’s kitchen to see how the Bodbyn looks next to bright white subway tile. She has warm lighting too. Also, Ikea has a new door, Akstad that is bright white. Hope you find something you like.
