Have you ever wondered why public toilets are U-shaped? Well, we have found the answer.
Public toilets often have a U-shaped gap in the seat, yet the toilet seats at home go all the way round and it all goes down to hygiene as most public authorities in the US have specific plumbing codes.
According to The Sun, the one in California says: “All water closet seats, except those within dwelling units, shall be either of the open front type or have an automatic seat cover dispenser.”
The gap in the seat is meant to give the user a little breathing room to avoid touching the seat with your genitals and provide one less place where urine could splash.
The gap in the seat is also meant to make it easier for women to wipe, according to Lynne Simnick, the senior vice president of code development at the IAPMO – International Association of Plumbing and Mechanical Officials.
There might also be something in the fact the seats with the gap are cheaper to produce and less likely to get stolen.
