The idea of peeing in the shower often surprises people because it’s something many secretly do but rarely admit.
Here’s what happens, broken down by facts, myths, and environmental considerations:
What Actually Happens (The Science)
-
It’s Mostly Sterile: Despite common belief, urine is not sterile in the bladder (it contains some bacteria), but it’s generally very low in pathogens, especially in healthy individuals. The small amount that hits your skin or the shower floor is quickly diluted and washed away by water and soap.
-
No Health Risk (For You): For a healthy person, peeing in the shower poses no medical risk. Urine is about 95% water, with the rest being salts, urea, and electrolytes. It doesn’t harm your skin or feet in the brief moment before it’s rinsed away.
-
It Won’t “Train” Your Bladder: A common myth is that the sound of running water will condition you to urinate every time you hear it. This is largely unfounded for adults. The reflex is stronger in young children but isn’t a concern for most.
The Surprising Benefit (Environmental & Practical)
-
You Save Water: This is the biggest argument in its favor. Toilet flushes use 1.6 to 5 gallons (6–19 liters) of water per flush. If you pee in the shower instead, you’re effectively using zero extra water to dispose of that urine. If everyone in a household did this occasionally, the water savings add up significantly over time.
The “Gross” Factor & Considerations
-
Hygiene: If you’re sharing a shower, it’s courteous to check with others who use it. While scientifically harmless, some find it unhygienic or unpleasant.
-
Drain Care: Urine is slightly acidic, but in the large dilution of shower water, it poses no risk to your pipes. However, if you have a septic system, the extra urea can actually be beneficial for the bacterial balance.
-
Public or Shared Showers: Don’t do it. The hygiene and courtesy rules are different in gyms, dorms, or public facilities.
What Doctors & Environmentalists Say
-
Medical Verdict: No issue for healthy individuals. Some urologists even suggest it can help break the “pee anxiety” some people feel.
-
Environmental Verdict: Organizations focused on water conservation (like the “Go with the Flow” campaign from a few years ago) have championed it as a simple way to reduce household water waste.
The Bottom Line: While it may seem taboo, peeing in the shower is harmless for most people and good for the planet. The main “surprise” is how much water you can save over a lifetime by skipping just one flush a day. The biggest factor is really personal (or household) comfort and etiquette.
So, if you do it, you’re not alone—and you’re making a tiny, eco-friendly choice. If you don’t, that’s perfectly fine too
