Public toilets, seemingly trivial urban facilities, are a vital reflection of a city’s public service quality and civilization level. The global “toilet revolution” has achieved remarkable progress worldwide, driven not only by supportive policies but also by technological innovation and standardized, socialized management upgrades. As an indispensable infrastructure of smart city construction, smart public toilets represent a key component of modern urban public services.
Empowered by advanced technologies including 3G/4G, Wi-Fi wireless communication, the Internet of Things (IoT), big data, cloud computing, artificial intelligence (AI), and blockchain, modern smart toilets realize intelligent supervision and efficient operational management. These technological upgrades deliver safer, more practical, comfortable, and hygienic public restroom services, greatly improving users’ toilet experience while comprehensively enhancing urban environmental sanitation standards and overall urban civilization. With integrated digital systems and human-centric design, many smart public toilets have even become popular urban check-in landmarks.
Smart public toilet construction mainly focuses on two core dimensions: user-centric service experience and refined intelligent operation management.
Prioritizing public user experience, smart toilets are equipped with full-suite intelligent hardware and software systems. They support real-time monitoring of air quality, stall occupancy, passenger flow, fresh air and deodorization status, and the consumption of toilet paper, hand sanitizer, and garbage capacity, alongside automatic lighting control. These intelligent sensors and systems enable automatic lighting, intelligent ventilation, smart deodorization, automated cleaning reminders, and one-click emergency rescue functions.
Through mobile apps, WeChat official accounts, and mini-programs, users can quickly locate nearby public toilets and check real-time stall availability anytime. Beyond basic restroom services, smart toilets offer diversified amenities such as mobile phone charging stations and intelligent vending machines. Feminine hygiene products are also available for purchase in female restrooms, mother-and-baby rooms, and gender-neutral accessible restrooms, fully catering to diverse user needs and optimizing the overall public experience.
For operational management, most smart toilets are fitted with outdoor display screens that present real-time data including stall status, weather conditions, indoor air quality, consumable stock, user reviews, and cleaning and disinfection records. Meanwhile, the screens support public welfare publicity, tourism promotion, and commercial advertising, creating a sustainable “commercial-supported toilet operation” model. This innovative mechanism generates stable operating revenue, effectively supporting long-term daily maintenance and sustainable operation of public toilet facilities.
Small as they are, public toilets bear great significance for people’s livelihood. Celebrated annually on November 19, World Toilet Day highlights the importance of hygienic, accessible public restroom facilities. Smart toilet technology has thoroughly solved the long-standing pain points of traditional public toilets — difficulty in finding restrooms, insufficient usable stalls, and poor service conditions.
Looking ahead, the core focus is to accelerate the popularization and large-scale upgrading of smart public toilets. By establishing long-term standardized management mechanisms, promoting intelligent renovation of more urban public toilets, and continuously optimizing service and management standards, we will further empower the construction of modern, intelligent, and high-quality cities, bringing smarter and more humane public services to urban residents and visitors.
