Korea today treats electronic bidets as an essential part of everyday life. From high-rise apartments in Seoul to countryside homes, it’s no longer unusual to find a bidet installed in the bathroom. But how did Korea, once unfamiliar with this concept, embrace bidets so quickly and completely?
The answer lies not just in technology, but in a unique blend of housing realities, cultural habits, service innovation, and smart marketing. Let’s dive into how electronic bidets became a national standard in South Korea.
Small Homes, Smaller Bathrooms
Korea—especially Seoul—is one of the most densely populated regions in the world. Starting in the late 1980s, rapid urbanization and an apartment boom changed housing structures dramatically.
Naturally, with smaller homes came smaller bathrooms. In many cases, the limited space barely accommodated a bathtub, toilet, and sink.
Installing a separate ceramic bidet unit, as seen in traditional European designs, was simply impossible.
In this context, an electronic bidet seat that attaches directly to the toilet was the only realistic solution.
It offered cleanliness and comfort without requiring extra space, fitting perfectly into the practical needs of Korean homes.
Inspiration from Japan’s Washlet
In the mid-1980s, Japan’s TOTO introduced the Washlet, an innovative toilet seat with built-in bidet functions.
Korean companies took inspiration from this but didn’t simply copy it.
Instead, they adapted the idea to suit Korean realities—developing slimmer designs, Korean-language control panels, and compatibility with a wider variety of toilet models.
Through this localization, the Korean-style electronic bidet was born, offering a more affordable, flexible, and user-friendly product that gradually gained traction, especially in Seoul.
Rental Services Lowered the Barrier
The real breakthrough came not just through technology but through an entirely new business model: rental services.
Unlike Japan, where consumers usually purchased their bidets outright, Korean companies like Coway and ChungHo Nais offered low-cost monthly rental plans.
Consumers could install a bidet at home with no upfront costs and enjoy benefits like regular maintenance, nozzle sterilization, and free repairs.
This made bidets accessible to the average household and transformed the device from a luxury item into a practical necessity.
How LuLu Bidet and a Jingle Changed Everything
Another critical factor in bidet popularization was emotional marketing.
At first, even mentioning bidets felt awkward for many Koreans.
But Coway’s “LuLu Bidet” advertising campaign broke down those barriers with a catchy jingle:
“LuLu~ LuLu~ Clean and Fresh~”.
Instead of focusing on the technical aspects, the ads emphasized cleanliness, comfort, and family usage, featuring happy children and parents.
This approach helped normalize bidets emotionally, making them seem friendly, familiar, and a natural part of modern life.
Thanks to LuLu Bidet, Koreans started to feel that using and even talking about bidets was perfectly natural and even desirable.
From Seoul to the Countryside
Initially, bidet adoption exploded in newly built apartments in Seoul.
Having a bidet became a symbol of modern, hygienic living.
This trend quickly spread from the capital city to regional cities, small towns, and even rural villages.
Today, even in the countryside, it’s common to find a household with an electronic bidet, proving how deeply the culture has taken root nationwide.
Conclusion
The rapid rise of bidets in Korea wasn’t driven by technology alone.
It was a perfect storm of limited space pushing innovation, cultural comfort with water-based hygiene, localized adaptation of Japanese ideas, clever rental service models, and successful emotional marketing.
Starting from Seoul, bidets have now spread to every corner of Korea, becoming an indispensable part of everyday life.
