4. It saves toilet paperWater isn’t the only thing you’ll save by peeing in the shower; for women, you might be able to save as much as one roll of toilet paper every two months by peeing in the shower. Okay, so that’s not much, but it’s still something, right? How about the fact that just reaching for the toilet paper can expose you to more germs than anything on the actual toilet seat? That’s right, toilet paper is disgusting, and peeing in the shower is just fine.
