1. We have room to wash dishes on one side of the sink and fit a drying rack on the other side.
2. We can easily fill our bucket and watering can in the sink.
3. We don't have a washing machine in our house but, in between trips to our friend's house for laundry, we have plenty of room to wash out clothes in the sink. (We hang things in the shower to dry.)
4. We can hide away all the dirty dishes from a dinner party in the sink and not think about them till our guests are gone.
Just how big is the sink? We went with a 30x18-inch sink basin that's 10 inches deep. The Kraus model we picked came with a removable rack on the bottom, and I'd never want a sink without one now. Pots don't scrape the bottom of the sink. Not to mention that the rack makes a great, built-in drying rack. Our Kraus facet is high enough to slide buckets, growlers and the like under it to fill, plus it has a pull-out sprayer that lets us get water anywhere we need it in the sink.
Best of all, when Bill cut the butcher block countertop, he was careful to preserve the full section of wood he cut out. We drilled a finger hold in the middle, then split the piece in two. Now we can cover one or both sides of the sink when we need more counter space or want to hide away unwashed dishes. When we want the sink open, the wood sections fit in the space behind our stove where we store pans and our pizza peel.
