This study presents case studies for an innovative function and form of a toilet that would be efficient for ecology and the prototypes and the process of designing a waterless toilet to address the water scarcity issue in the Republic of Korea are described. The ergonomic sitting posture needed for defecating is discussed and the design a waterless toilet is described. This was achieved by conducting focus group interviews with a user engagement approach to understand the needs of users and how to improve the design of a toilet. The results led to the development of an experiential service design project to raise awareness of water scarcity as well as new technology to remove the odor caused by toilets. The research aim was to understand the concept of several features of toilet design and the new paradigm of the production and culture of defecating systems. A descriptive analysis is used to present the current features and how they are implemented. An exploratory analysis was conducted based on the factors of sustainability, ergonomic posture and degree and aesthetic form.
