Taiwan’s population aged 65 and above is projected to exceed 20% of the total population by the end of 2025, marking its transition into a super-aged society. Bathrooms and toilets are among the most common sites of accidents in older adults’ homes. This study aims to (1) investigate the functional roles and spatial constraints of grab bars used by older adults in bathroom spaces, as well as examine alternative support methods and their associated risks when grab bars are absent; (2) conduct field observations and semi-structured interviews with one to three older adults, revealing that in the absence of grab bars, they often rely on washbasins to support sit-to-stand and transfer movements, which poses a high risk of falls; and (3) summarize observed issues and engage assistive device and spatial design experts in an expert review to integrate empirical evidence and professional insights and propose safety-oriented grab bar design recommendations. The findings provide practical references for understanding older adults’ support behaviors and grab bar design needs. They highlight the importance of optimizing spatial configuration and ensuring accessibility while maintaining safety, aiming to reduce fall risks, enhance independence, and improve confidence during daily activities. Ultimately, the study seeks to assist older adults in living safely and with dignity in familiar home environments, supporting the concept of aging in place.
