The increasing number of elderly people in Indonesia cannot be separated from the increasing life expectancy in the society. Elderly people are often faced with a situation that requires them to live independently. However, elderly find it quite difficult to undergo their daily activities independently because of the deterioration of vital functions in their body and the lack of supporting facilities which can accommodate their needs. This research was conducted at a retirement home named Senjarawi located in Bandung, Indonesia. Bathroom is a place where elderly people always perform daily activities such as bathing and defecating. However, the facilities in Senjarawi’s bathrooms are not designed specifically for elderly so they often get unconscious or even pass away. The participatory method used in this research is Usability, Safety, and Attractiveness Participatory (USAP) Design Model. USAP design model is one of the techniques of participatory design, where elderly as users participate actively in the design process. The final results of this research are made in the form of low-fidelity prototypes, e.g. three-dimensional images of bathroom.
