Through　field　research　on　the　home　bathing　scenes　of　assisted　elderly　people,　grounded　theory　was　used　to　code　the　original　information　of　user　interviews　and　bathing　behaviors,　and　the　various　attribute　needs　of　assisted　elderly　people　for　bathing　behaviors　were　summarized.　At　the　same　time,　the　analysis　was　used　as　indicators　in　the　analytic　hierarchy　process.　The　layer　is　being　constructed;　using　this　as　the　design　index　for　aging-friendly　bath　products,　experts　are　invited　to　evaluate　and　calculate　the　weight　value　of　each　index,　and　analyze　the　importance　data　of　the　indicators　to　design　an　aging-friendly　bath　product;　finally,　the　fuzzy　comprehensive　evaluation　method　is　used　to　test　whether　the　plan　is　satisfactory.　Degree,　the　study　obtained　the　evaluation　results　of　this　program,　proving　the　feasibility　of　combining　grounded　theory　and　fuzzy　level　analysis,　making　the　theory　and　practice　effectively　connected　and　exerting　practical　significance.　The　combination　of　grounded　theory　and　fuzzy　level　analysis　can　systematically　carry　out　quantitative　design　and　evaluation　of　products,　reduce　subjective　influencing　factors　in　the　product　design　process,　make　the　design　more　scientific,　objective　and　rigorous,　and　provide　effective　program　reference　and　optimization　ideas　for　subsequent　similar　aging　product　design.　©　2024　The　Authors.
