Very few people will actually admit to peeing in the shower, but in reality a lot of people do it.
And if you don't, you might want to start.
Peeing in the shower actually boasts a lot of benefits. According to Mic.com, peeing in the shower once a day can save you from buying a roll of toilet paper every 50 days.
And fascia specialist Lauren Roxburgh recommends women squat and pee in the shower to engage pelvic floor muscles, which can actually lead to better sex.
But the biggest benefit is all the water you'll save. In 2014, Debs Torr and Chris Dobson, students at the University of East Anglia in Norwich calculated that if all 15,000 students at their school peed in the shower once a day the school would "save enough water to fill an Olympic-sized swimming pool 26 times," the BBC reported.
According to the United States Environmental Protection Agency the standard toilet uses 1.6 gallons (6.05 litres) per flush, while older models can use as much as 7 gallons (26.49 litres) per flush. Considering the average person uses the toilet six to eight times a day, that's a lot of wasted water.
If the thought of peeing in the shower still seems gross, you can also reap those water saving benefits by practicing selective flushing — you know the saying, "if it's yellow, let it mellow" — or swapping out your old toilet for a new, high efficiency one.
