In the development process of the friendly restroom, information was needed about user preferences regarding supports and personal hygiene in the toilet. As literature studies did not yield the required information, two user tests were held with supplemental questionnaires. The main test was carried out with seniors, the preliminary test with students. The preliminary test helped to fine tune the main test and to assess its risks. The test was held with a setup that consists of an height adjustable toilet bowl and various adjustable supports around it. The setup also contained a newly designed washbasin. The results from this study are a preliminary insight in the preferred types of supports and corresponding preferred heights and positions for these supports among elderly. Furthermore, insight was acquired in attitudes towards personal hygiene in the toilet.
