Speaking to CNN, professor of urology at Cedars-Sinai in Los Angeles, Dr. Karyn Eilber, said there's “no downside” and that it is “just convenient for some people”.
“It’s really personal preference that people don’t like to associate a place where you clean yourself in the shower to a place where you also do some elimination,” she said.
Urologists agree that there are no health hazards when taking a pee in the shower, and it is unlikely to clog up the drains.
Dr. David Shusterman, a urologist and chief physician at Modern Urologist in New York City, also dismissed the common argument that peeing while standing up can have negative effects on women’s pelvic muscles.
It is a common argument that the position does not allow a female’s pelvic muscles to relax completely, meaning there is extra straining and an inability to empty the bladder completely.
“In a warm shower, it’s very easy for you just to relax the sphincter and let the urine come out,” he told CNN.
“Contrary to claims of urinating in the shower being unhealthy, I think it’s actually healthy.”
