Abstract: The present invention extends an interior corner piece to create flange portions of a ceramic or porcelain molding. The structure of the invention can provide a sanitary transition between a wall and a floor by smoothing out and raising the surface away from a sharp corner or crevice. The invention also moves edges of the corner piece farther away from the inside corner. This can improve sanitation and allow for easier cleaning. This structure can promote a smoother installation and more uniform molding scheme by possibility improving the stability of the design to allow the molding piece to lie flush in the corner. The features of the invention may promote easier installation, better sanitation, and a pleasing appearance to the molding scheme.
