* It's a comic book: The world of Superman is full of fantastical elements. We're meant to suspend our disbelief and enjoy the story. It's not meant to be hyper-realistic.
* No real answer: There's no official explanation in the comics or movies about Superman's bathroom habits.
* Theories abound: Fans have come up with some creative ideas, such as:

* Kryptonian biology: Maybe Superman has a different digestive system than humans.
