Water itself is surprisingly cheap. The average cost is about 0.004 cents per gallon. That sounds like nothing, but a 40-gallon bath uses roughly 16 cents in water. If you live in a drought-prone area like California or Australia, you might be paying twice that—around 30 to 40 cents. It’s still cheaper than a single slice of avocado toast.
But here’s the kicker: you’re also paying for wastewater treatment. That water doesn’t just disappear; it goes to a magical place where people in rubber boots process your soapy sins. Add another 10 to 20 cents for sewage. So your total water cost is about 26 to 60 cents. Congratulations, you’ve just paid to destroy evidence.
