Ask who invented the bidet and most people guess Japan or picture a sleek electronic seat, but the answer reaches back roughly three centuries to a French bedroom, not a bathroom. The device that so many Americans are only now discovering has a long, surprisingly aristocratic backstory. Understanding where it came from also explains why it looks the way it does and how it split into two very different products: the standalone porcelain basin and the modern spray seat. This is the origin story, not a buyer’s guide, so we will stick to the people, dates, and inventions that shaped the fixture.

France in the Early 1700s: The First Basins
The bidet as a recognizable object appeared in France around 1710. It was not plumbed and it was not tucked into a water closet. Early bidets were pieces of bedroom furniture: wooden frames holding a porcelain or metal basin that a person straddled to wash the private areas with water poured by hand. Wealthy households kept them beside the chamber pot, and servants filled and emptied them.
Historical records frequently credit French furniture makers with the design, and the name most often attached to the invention is Christophe Des Rosiers, a furniture maker said to have built bidets for the French royal household in the first decade of the 1700s. Documentation from that era is thin, so pinning the invention on a single person is genuinely difficult. What the records make clear is that the bidet was born as a craftsman’s product in France, decades before flushing toilets were common.
What the Word “Bidet” Actually Means
The name is a clue to how people once used it. In French, “bidet” means a small horse or pony. Because you sat astride the basin the way you would mount a pony, the word stuck. That etymology tells you the posture was the whole point: the user straddled the low basin rather than sitting back on it. The playful name survived even as the object turned from wooden furniture into fixed plumbing.
From Furniture to Plumbed Ceramic
Through the 1700s and 1800s, the bidet slowly migrated from a portable basin toward a permanent fixture. Two big changes drove that shift. First, ceramics and sanitary ware improved, so manufacturers could mold durable, cleanable porcelain bowls. Second, indoor plumbing spread through European cities in the 1800s, bringing running water and drains into the home.
By the late 19th and early 20th centuries, the freestanding ceramic bidet we recognize today—an oval bowl with hot and cold taps, mounted on the floor next to the toilet—had become standard equipment in French, Italian, Spanish, and Portuguese bathrooms. In much of southern Europe and Latin America, a bathroom without one still looks incomplete. That version stayed close to its 1700s roots: a dedicated basin you use after the toilet, filled from a faucet instead of a pitcher.
Why the Bidet Skipped the United States
If Europe embraced the bidet, why did American bathrooms ignore it for generations? Part of the answer is a matter of bad first impressions. During World War II, many American soldiers first encountered bidets in European hotels and brothels, and the fixture picked up an unfair association that made it a hard sell back home. American bathrooms were also built smaller and standardized around a single toilet, leaving little floor space for a second basin. For decades, the bidet stayed a curiosity that most Americans knew only from travel.
Arnold Cohen and the American Reinvention
The story takes a turn in the 1960s, and this chapter is the one that eventually made bidets practical for the U.S. market. Arnold Cohen, an American inventor sometimes called the “father of the bidet seat,” built an integrated warm-water washing device after a family member suffered a painful medical condition. In 1964 he founded a company, the American Bidet Company, to sell a seat that mounted onto an existing toilet and sprayed warm water.
Cohen’s insight was decisive: instead of asking homeowners to install a second floor fixture, put the washing function into the toilet seat itself. That idea removed the space problem that had kept bidets out of American homes. He reportedly struggled to advertise the product in a squeamish era, but the concept—warm-water cleansing built into the toilet—became the template for everything that followed.
Japan Perfects the Electronic Bidet
Japanese manufacturers took the seat concept and turned it into a technology category. The Japanese company TOTO licensed and refined early electronic seat ideas, then launched the Washlet in 1980. The Washlet added the features people now associate with high-end bidets: a heated seat, an adjustable warm-water spray from a retractable nozzle, temperature and pressure controls, and warm-air drying.
The product was a runaway success in Japan, where electronic bidet seats are now found in a large majority of homes and in many public restrooms. TOTO’s marketing, including a memorable campaign in the 1980s, helped normalize the once-taboo device. The modern smart toilet—self-cleaning nozzles, automatic lids, deodorizers, night lights—descends directly from that 1980 Washlet.
So, Who Really Invented It?
There is no single inventor, and that is the honest answer to who invented the bidet. The original basin came out of early 1700s France, with Christophe Des Rosiers and unnamed French furniture makers usually credited for the first designs. The plumbed ceramic version evolved across Europe through the 1800s alongside indoor plumbing. The bidet seat—the form most Americans buy today—was reinvented by Arnold Cohen in the United States in the 1960s and then perfected by TOTO in Japan starting in 1980.
Put those pieces together and the timeline makes sense. A French luxury for the aristocracy became a European bathroom standard, got reengineered as an American add-on seat, and finally matured into the electronic fixtures now spreading back into U.S. homes. Roughly 300 years separate the wooden basin from the app-controlled smart toilet, but the goal never changed: wash with water instead of relying on paper alone.
The Modern American Comeback
For most of the 20th century, the fixture remained rare in the United States, but the last two decades flipped that quietly. Affordable non-electric attachments from brands like Tushy, Luxe, and Brondell brought the entry price down to $30 to $100, letting a curious homeowner clamp a sprayer onto an existing toilet in about 20 minutes with a single wrench. No second fixture, no remodel, no plumber.
The tipping point came in early 2020, when a nationwide toilet paper shortage sent shoppers looking for alternatives. Bidet sellers reported sales spikes of several hundred percent, and many first-time buyers simply kept using the fixture afterward. Three centuries after a French furniture maker built the first basin, the bidet finally started shedding its foreign reputation in American homes, closing the loop on a very long journey.
Key Milestones at a Glance
- c. 1710: First bidets appear in France as bedroom furniture; Christophe Des Rosiers often credited.
- 1700s-1800s: The basin evolves into plumbed ceramic as indoor plumbing spreads through Europe.
- 1960s: Arnold Cohen founds the American Bidet Company (1964) and popularizes the warm-water washing seat.
- 1980: TOTO launches the Washlet in Japan, defining the modern electronic bidet.
Next time someone at the dinner table asks about the fixture’s origins, you can give them the full arc: a French pony-shaped basin, a European standard, an American seat, and a Japanese electronic marvel. The bidet was not invented once. It was invented, reinvented, and refined by different people on three continents over three centuries.
That layered history is also a useful lens for shopping today. The standalone porcelain basin you see in an older Italian bathroom is the direct heir of the 1700s French design, while the heated spray seat on the shelf at a home center descends from Cohen’s 1960s invention and Toto’s 1980 Washlet. Knowing which branch of the family tree a product comes from tells you exactly what to expect: a separate fixture that needs floor space and plumbing, or an add-on that bolts to the toilet you already own.
