Abstract: A method of installing a low step entryway in a bathtub wall structure which comprises a front wall portion, a rear wall portion and an upper edge portion which together define an interior wall space. A portion of the front wall is cut away to form a cutout which is shaped in the form of the entryway which is being installed. After the open entryway is formed, a saddle structure is installed in the entryway. This saddle structure is shaped the same as the entryway opening which is being provided, and it comprises a lower middle portion forming a horizontal bottom wall, and two side saddle members extending upwardly extending components of alignment, with these providing side surfaces for the entryway.
