Compared with a lot of comprehensive and alternative studies on elderly housing facilities until now, specialized studies of dimensional and detailed standards have hardly made. Therefore we intends to examine the status of bathroom planning on representative elderly housing facilities in Korea. As the methods of this study, we executed a field study into five representative elderly housing facilities in Korea. We visited each two units out of the outstanding 5 facilities and surveyed the total ten bathrooms. Then we analyzed the space planning of them and the state of bathroom commodities, and measured the bathroom equipment. In addition, we collected questionnaires about satisfaction, preference, and problems from the residents. As a result, most of the bathrooms had powder rooms and were furnished with bathtubs(4) and shower stalls(6). One or more grab bar and emergency calling system were provided but the heights of the handles were different from each bathroom. The floor material of bathroom should be installed with no-slippery material.
