If yes, what does it corrode better than water?

I'm not exactly certain, but it probably is more corrosive to some materials simply because of the variety of chemicals it contains. The pH of urine is usually close to neutral, but can be acidic or alkaline as well. Presumably, the more acidic or alkaline it is, the more likely it is to corrode something.

Is that tap water or distilled water?

The mixture of salts is also likely to contribute to corrosion.

"Corrosive" means nothing if you don't specify for what. If you have to dissolve salt, water is certainly more corrosive, for example.

I left it open on purpose. I wanted to know what it corrodes better then water. Seems from your answer that it corrodes salts LESS than water. How about concrete?

Do you want to make holes on concrete using urine? :D
No, seriously, I sincerely don't know, but I think it "corrodes" more than water, just because when it dries it leaves solid chemicals that can expand, on accumulating inside the concrete's pores.
