You can always stick pots or pans into a single bowl and use it like a double. Everything fits in the single. But if you usually do dishes by hand and use both basins you may want to stay with a double...

How wide is your sink base? If it's not at least 33" (and really, at least 36"), I would go with a single bowl. If your base will be at least 36" and this is your only sink in the Kitchen for prepping, then you might like a 60/40 double bowl sink I would definitely stay away from a double bowl sink with equal size bowls (unless the sink base is at least 48" wide and the sink is wide enough to fill it up).

If you have a prep sink and it's located correctly, then you might go ahead with a single bowl regardless of the sink base size.

My DH cleans up and he prefers a 60/40 (really more like 67/33) double bowl sink. He uses the small bowl for soaking silverware and the like while he uses the large bowl for rinsing, if needed (some things do need rinsing or soaking - but not all.) He doesn't have to worry about where to store a dish bin when not in use (we don't have room to store such a large item) or have to get out a pot to use to soak something (none would really fit silverware).

The prep sink that I use is a single bowl, but it's only 15-3/4" square - interior (yes, I wish it were wider).

There are pros & cons to both configurations - think about how you work. Will you and your DH be sharing the sink - one prepping/cooking while the other cleans up or maybe two of you prepping. If so, a double bowl sink may be better. If you are the sole cook and bottle washer (or your DH is), then maybe a single bowl will suffice - but be sure you plan how you will handle the need for a smaller bowl when you don't want to fill up the expanse of a single bowl sink - have a dish bin handy, for example.

Another option is a double bowl sink with a low divide. It's a double bowl sink, but the divider is shallower than the entire sink so, if needed, a pan's handle or a large refrigerator shelf will fit inside the sink.

For reference, here's my cleanup sink and what it holds:

The large bowl holds everything except the full-length deli drawer and glass shelf from my refrigerator. All of my pans, pots, cookie sheets, etc., fit in the large bowl.

We just put in a big single bowl (I wanted double because I was used to it, DH wanted single. He does the dishes so he won.) I LOVE it! Would never go back.

We've always had a double bowl and decided to stick with that; however, 60/40 (as buehl mentioned, 36" sink base). We do our rinsing/scraping, etc. into the 60 side, and it's nice not having to de-grease/sterilize/wash an entire single bowl sink every evening. We regularly cook large pots of stews and soups that are still very hot by bedtime, so we'll use the 40 side for the water bath chill-down.

We needed the 60 on the right side (tough to track down!), so ended up with the Kraus 104-33. To maximize sink space, we looked for a 40 side that extended as far back as the 60.

Be careful when considering these deeper 9-10" sinks: make sure your main drainpipe is situated lower than your garbage disposal exit pipe. We goofed on this one detail and ended up dismantling our GD. No biggy, though, as we're about empty nest, and dumping the strainer basket daily is easily done. And an unanticipated bonus is increased under sink storage. :)

I've always had a double sink. 50-50 for years and then "upgraded" to 60-40
and then 70-30. See where I'm headed..... now I have a single. I will
admit that it did take awhile to get used to, but I love it, as does my
DH! And as a bonus I have the drain offset to the side so have room for
trash/recycling plus my garbage disposal in my sink cabinet. Another
plus for me is that having the GD in a single sink means that scraps are
never dumped into the wrong sink. Life is good!

I have a pull down faucet now (Kalia). My previous one was a pull out (KWC) and it was good as well. My only recommendation is to make sure that your faucet is high enough that it doesn't get in the way of whatever you are working with in the sink.

I remodeled my last kitchen in part because I wanted to get rid of the double bowl sink LOL. Since then I've only had single bowls, and I'd never willingly return. In fact, if I moved someplace that had a double bowl, I'd be inclined to rip it out and replace it.

Most of our customers (80%) select the single bowl when they update/remodel their kitchen. See some popular options below.

I also vote for single bowl, and make sure that the drain is offset to either the rear or one side (preferably in a corner.
