I have 2 single basin sinks: one that is 30" and one that is a 15" prep sink (any smaller would be too small). I absolutely love this configuration.

Others who have posted in favor of double basins typically say they want to be able to separate wash from rinse, or dirty dishes from food prep, or some other reason to separate things into 2 basins. I rarely handwash dishes, and when I do I use just a cloth with some dish soap on it and then rinse under a slow tap, so I don't have a need for separate wash/rinse basins. Others that have single basins will keep a small tub under the sink and fill it up only when hand washing.

What is the fascination with disposers? I really don't know. I've almost always had one, rarely used it, and in my remodeled kitchen I don't have one at all. I don't miss it. I use a deep basket instead and thoroughly clean it every few days.

Are prep sinks really that great? I say yes. Others say no.

Search the old threads on this forum that cover all of these questions ad nauseum. And even after you've read all the opinions, you still might disagree - and that's ok, it's your kitchen.

Have always preferred double basin so I can put a dish drainer in one.

I don't think I have ever seen anyone put a dish drainer in a sink. I've always seen them placed off to the side of the sink.

I grew up with double bowl sinks, but we didn't have a dishwasher. I can't understand, if you have a dishwasher, why you would really need a double bowl. I put most of my stuff in the dishwasher. For the few things I hand wash (pans, some knives etc) I just set them on the counter when washed and dry them and put them away when I am done washing. Not a big deal. I like being able to fit pans all the way in the sink. Mine is 10" deep, which is good I think. If it were deeper I think it would be too hard to reach. I have a 26" and honestly can fit everything in there. I can't understand what people do with huge sinks. As far as prep sinks, my kitchen is smaller and I wouldn't waste the counter space putting in a 2nd sink. I think they might be useful if you had more than one person preparing more than one dish at a time.

Personally loving my new workstation sink from Ruvati. It's kind of the best of both worlds. I have always had double basin before and it was my preference but for a recent remodel went with the Ruvati. There are nicer brands but that one fit my budget and house best. It has a ledge which lets me use a cutting board and a drying rack which lies flat. It also comes with a built in strainer. Might be something to look into.

I guess I am one of the few who prefer the double bowl. I have never had a problem fitting my large pots in the sink. I like that one side can be used for soaking things and I still have a side that is usable. I also like having a drain that does not have a garbage disposal. There are things I do not want going into the disposal, for example when I wash the garden dirt off my hands.

It must be where I live, because I don't know anyone with a garbage disposal. What are the benefits of having one? Downsides?

I’ve never really thought about it since every place I have lived in has had the disposal. I know some people put all their food scraps in the disposal. I don’t put everything in there but it is nice to not have to worry about food scrapes going in the drain. Scraping plates, peeling carrots, or potatoes, etc.

Some downsides, you need to be careful that something isn’t in the drain when you turn it on. I have “chewed” up a spoon before. Once a glass broke in the sink and glass shards fell in the disposal, that was fun trying to get them out. You also need to clean it and replace it every so often.
