This paper aims to explore the key factors in the elderly home bathroom context and the impact of contextual factors on the product, guide the evolution of man-machine interaction to a more inclusive, active and human direction, optimise the experience of using elderly bathroom products and improve the quality of retirement. Based on context awareness, three types of age-appropriate home bathroom contexts, namely user context, environment context and task context, are proposed using theoretical combing. Through such methods as household research, behavioural observation and interviews, the characteristics of the three contexts are analysed and needs extracted.The product design strategy for age-appropriate smart home bathroom products is proposed to develop the whole bathroom, build a continuous experience with product interconnection, give growth to age-appropriate products and focus on inclusive design of bathroom products. In addition, contextual research to analyse key points and generalise strategies can reflect the usage habits and bathroom space characteristics of elderly users and derive potential user needs, thus guiding the direction of ageing-friendly bathroom product design in line with usage logic and providing a more comfortable and convenient usage experience for the senior citizens.
