Mom was all for a deeper sink, too. She ought to know. When she built her house back in 1989, she didn't make any special decisions about the kitchen sink, and so they just put in your standard contractor-grade sink. I know at the time mom was thinking, hey, I'm going to have a dishwasher, I won't need a big sink to do dishes. But she soon learned that sometimes you don't want to fill a quarter of your dishwasher with just one big stock pot, a giant colander or mixing bowl. I'm sure she wishes she could put in a nice deep sink like the one we picked out for me, but since there is nothing really wrong with hers, she can't justify changing it. Maybe someday.We were determined to get the deepest sink we could find, but we ran into a bit of a snag. We found out that our choices would be rather limited because we had a width restriction. I think there were about three models for us to choose from. We picked one we like, and I am very happy with it. The sinks with three bowls are awfully nice, though, if only one would have fit.
Anyway, mom and I highly recommend splurging for this extra if you are in the market for a new kitchen sink.
