Research on the Variable Module Space of Elderly-Friendly Bathrooms Based on Movement Behaviors

As China enters an aging society, home-based elderly care has become the mainstream. Therefore, it is necessary to improve the safety and comfort of the elderly when using bathroom facilities at home. Through the identification and research of existing problems, this paper uses the research methods of movement behavior analysis and ergonomic principles to draw more rigorous conclusions, and proposes a complete optimization design plan for elderly-friendly bathroom spaces, including three modules and two spatial layouts. Meanwhile, the innovation points are put forward to illustrate the design thinking different from the past. Combined with existing literature, the design key points and practical value of elderly-friendly bathroom spaces are explored, aiming to provide theoretical support and practical guidance for improving the quality of life of the elderly.
