Hovering Over Public Toilets: What It Does to How Well Your Bladder Empties

If you hover over public toilet seats, you have plenty of company. In a 1991 survey of 528 women at a British gynecology clinic, 85% usually crouched over public toilets. 12% lined the seat with paper, and 2% sat directly on it. Even at a friend’s house, 38% crouched.¹

Four studies, four groups of women

Study	Who was tested	What it found
Liverpool, 1991	80 women having bladder tests, each peeing both ways	Crouching made the average flow 21% slower and left 149% more urine in the bladder1
West Virginia, 2019	30 young, healthy women with no bladder symptoms who had never given birth	No difference in flow rate or amount between hovering and sitting. Leftover urine wasn’t measured.3
East China, 2024	414 women with leaks, compared in 117 matched pairs	Women who hovered were more likely to have moderate-to-severe leaks than mild ones4
Taiwan, 2011	21 women averaging 65 with knee arthritis who struggled to crouch	Peeing standing up with a funnel device worked as well as sitting for flow and leftover urine5

How to read them together

• The slowdown showed up in women who already had bladder problems. The Liverpool women were at a clinic for bladder testing. The West Virginia women were young and symptom-free, and the authors called for a larger study.¹³ If you’re over 50 with urgency or leaks, the Liverpool group is closer to you.
• The China study is a snapshot. It can’t say whether hovering made leaks worse or whether women with worse leaks hover more.⁴
• The Liverpool study is small and 35 years old. We found no newer study that repeated its leftover-urine measurement in older women.

Why leftover urine matters

The NIA says holding urine “in your bladder for too long can weaken your bladder muscles and make a bladder infection more likely.” It also warns that rushing “may not allow you to fully empty the bladder.”² A crouch held under tension works against both.

What to do

• Sit all the way down when you can. Line the seat with paper or a seat cover if that’s what lets you sit, then let your weight settle and take your time.²
• If your knees or hips make sitting and standing hard, use grab bars or an accessible stall. In the Taiwan study, 17 of 21 women had no trouble using a funnel-style standing device.⁵
• Get checked if you often feel you haven’t finished, or your stream is weak or stop-start. A bladder scan or flow test measures what’s left behind. See what to report about bladder emptying.
• Burning, fever or cloudy urine? See how to know if you have a UTI.

Try: “I hover over public toilets, and I often feel I haven’t finished. Could you check how much urine is left in my bladder after I go?”

Laugh, Sneeze, Jump covers this research in Chapter 7’s section “Sit Down, Stay a While.” Its Three-Day Read, a three-day bladder diary, shows how often you go and when you leak. Its Red-Flag List in Chapter 3 includes trouble emptying and a weak or stop-start stream. See the book.
