Why do American public toilets have a peculiar horseshoe shape?
This is a front-loading toilet seat that is preferred by most public restrooms due to its compliance with the American Standard National Plumbing Code. The Code was created in 1955 and was further consolidated by the Uniform Piping Code developed in 1973 by the International Association of Plumbing and Mechanical Officials (IAPMO). The code states, "Wash toilets shall be provided with seats made of smooth, non-absorbent material. The seats of toilets intended for public use shall be of the front-opening type."
They were also designed with women in mind, according to Lynne Simick, the senior director of code development at IAPMO. The gap in the seat is designed to “allow women to wipe the perineal area after using the toilet without contacting the seat,” Simick notes that the design also benefits men. She says an open-front seat “eliminates an area that could be contaminated with urine” and also “eliminates the user’s genital contact with the seat.”
