As part of the ongoing "toilet revolution" in China, many public restrooms are transitioning from squat toilets to flush toilets. However, essential complementary measures, such as disinfectants and disposable toilet seat covers, have yet to be sufficiently implemented. This creates an uncomfortable and unhygienic experience for users, particularly women, who must come into direct contact with toilet surfaces, whether for urination or defecation. This project aims to offer a more hygienic solution for women using public flush toilets, with a strong emphasis on environmental sustainability and public health.
