No guarantees, in fact highly unlikely, that changing the sink will fix your draining issue.

Some of this is opinion, but a perfect sink will have /be:

- One large bowl -- makes it easier to wash large pots or baking sheets. You can always add a small container to soak silverware, etc., but you can't remove that blasted middle divider.

- Large. The sink is the single most-used item in any kitchen, so don't skimp on size. Bigger is better. If you're concerned about giving up counter space, consider adding a full-sized cutting board that can completely "cover it up".

- Stainless steel material -- builder-basic is fine /will last forever. My house was built in 1970 and the builder-basic stainless steel sink still looks /works great. Thicker material and soundproofing are kinda solutions looking for problems -- or, a way to convince you to buy something more expensive.

- One single drain -- preferably offset to the left or the right /not center of the sink. This means less plumbing under your sink /more storage. Also, with only one drain, you'll never put something down the side with no garbage disposal.

- Most people will tell you to choose an undermount sink, as it's easier to wipe the crumbs in -- no "bump" to get them over /no "bump" where gunk will build up and need to be cleaned with a toothbrush.

- People's opinions will vary on this one, but I love an apron /farmhouse sink. If you're short like me, it brings the sink a few inches "closer" to you and saves some wear /tear on your back. It also gives you a few extra inches of extra space behind the sink, which makes it easier to clean. The negative is that an apron /farmhouse sink makes the cabinet below feel farther back /deeper /darker -- a problem you can combat with a pull-out (either built-in or small tubs on wheels from Amazon).

Put just as much thought into your sink's details:

- I have a one-spout faucet with a pull-out spray. If anything better exists, I can't imagine what it is. Important: If you have the type with a controller that looks like it should be mounted on the left or right, mount it in the center -- this means you can reach it just as easily with either hand. This seemingly small detail really makes a difference in function.

- Note that the fewer items that are "built into" your sink /counter top, the fewer items you have to clean around.

- Consider whether you want a built-in dishwashing detergent squirter. I like-don't-love mine, but I think I'd love it if I also had a NeverMT to go with it. My complaints have to do with the messiness of refilling the bottle /having soap spill out.

- Consider whether you'd like to have an Instant Hot Water Spigot next to your sink. If your hot water heater is literally on the other end of the house (like mine), and if hot water takes 3-4 minutes to reach your kitchen sink, you might appreciate this small accessory.

In case it's not spam...

The first is probably the worst type of sink you could get.

Similar to Theresa's post, this is opinion and based on real-world experience with equal-sized double bowls, 60/40 double bowls (my preference if you only have one sink in the Kitchen), single bowls 15" wide to 36" wide. For the record, I'm dealing with a 36" single-bowl apron sink right now and, to be honest, I hate it! My husband is "meh" but he doesn't want to change it out at this time.

If you want a double-bowl sink, the sink base should be at least 33", preferably 36" or more, wide.

Then, the sink should have unequal-sized bowls. The sinks with the equal-sized bowls are the ones that gave double bowl sinks a bad name. The bowls are too small for bigger items and too big for small items/tasks.

Instead, look for one that's 60/40 or 70/30. Ideally, you want the large bowl to be at least 20" wide (interior width, left to right) and the small bowl at least 10" wide.

If you prefer a single bowl, then any sink base at least 24" wide will give you a nice size bowl of at least 21". Personally, I would prefer a 30" sink base to fit a 27" to 30" wide single bowl (interior width), but it all depends on the space you have available. For small Kitchens, a 24" sink base with a single bowl is a good compromise with functionality and available space.

Regarding whether you should get a Kraus sink, read the reviews on this site. Most people are OK with Kraus if you don't want a higher-end looking sink. Others say it starts rusting pretty quickly.
