The Effectiveness of Restroom Space in Public Facilities for Wheelchair Users：experiment for Evaluation and Verification Using a Real-Scale Model With Adjustable Spatial Size

This study aims to clarify the spatial size necessary to improve the convenience of restrooms for wheelchair users. To achieve this, experimental equipment was created to replicate a restroom for wheelchair users based on design standards and an actual restroom for wheelchair users in Koriyama City. This study identified that a user friendly restroom for wheelchair users requires either the dimension of the opening direction or the depth to be 2000 mm or more, and it is required that a φ1500 mm circle can be drawn without interfering with the toilet or walls in the floor plan of the restroom.
