ABSTRACT:
A floor drain extension for, and method of, elevating a drain plate of an existing floor drain after a refinishing layer such as tile has been applied onto the floor structure through which the floor drain is installed. The extension is generally annular shaped and structured to fit between the drain plate and the upper surface of the floor drain fixture so as to upwardly reposition the drain plate into a flush arrangement with the new refinishing layer surface. By proper preselection of the thickness and mounting hole pattern, the extension will easily be reinstalled after the refinishing layer is applied. Further, by temporarily bolting the extension atop the existing floor drain prior to application of the refinishing layer, a precise edge to edge abutting fit between the refinishing layer and the extension will be achieved.
