Answer 1

The important thing here: pee _while_ you are showering. You’re using water anyway to wash yourself, that’s why it’s better for the environment as the water that you use to flush the toilet is only used for flushing.

Answer 2

In a vacuum perhaps, but it’s also unsanitary if you’re peeing into a small vessel like a sink, because of splatter and stains, or into a bathtub that people use, for the same reason. So what you gain environmentally you’ll lose hygienically.
