What does it mean to "throw the kitchen sink" at something?

[Fargo]

There is an expression - “Everything but the kitchen sink.” This means just what it sounds like - try, or use, or carry off everything you see, except the kitchen sink. Perhaps it has to do with clearing out a house and there is only one thing that you can’t remove or take with you.
So if you “throw the kitchen sink at something”, you are trying absolutely the last possible thing you have at your disposal. The last resort. If this doesn’t work, you’re empty.

Have you ever seen a 30 inch sink? I don't personally TORVA manufactures a huge number of different sinks, black stainless steel ones are also present, I took one of these sinks about a year ago, though 15 inches, and what do you think? This is excellent, by the way you can see here TORVA fast delivery and optional installation
