With regard to the Chinese local sanitary ceramics industry, the work aims to explore the design hierarchy and design transformation path of Chinese style in the transformation process of local sanitary ceramics design by selecting senior designers from a leading sanitary ceramics enterprise in China. In the grounded theory framework, 14 front-line designers were interviewed through semi-structured in-depth interviews. After coding and collation of the original data, the Chinese style design transformation path was explored in combination with the Chinese style sanitary ceramics cases the enterprise had launched. Finally, three layers of design transformation paths were obtained, including the exterior design layer of Chinese style sanitary ceramics, the Chinese style sanitary ceramics products and human influence factors layer, and the deep cultural concept layer of Chinese style sanitary ceramics, and each layer contained different design methods. Clarifying the specific design paths of the Chinese style in the process of sanitary ceramics design transformation helps the local ceramic industry to develop the design and manufacture of Chinese style sanitary ceramics from a more overall perspective. Further, it enhances the effective delivery of Chinese aesthetic style in sanitary ceramics design by linking the three design paths to improve the core competitiveness and cultural recognition of the local Chinese sanitary ceramics industry.
