Abstract: A decorative cap and nut for securing a toilet base to a floor includes a top substantially disc-shaped member having an upper disc surface and a lower disc surface. The diameter of said disc-shaped member is substantially greater than the thickness thereof so as to lie substantially flush with the toilet base. A coaxial cylindrically shaped stem extends vertically downwardly from the top and is connected to the lower disc surface. The stem includes an internal thread adapted to be threaded onto a floor bolt that extends upwardly through an aperture in the toilet base. A slot in the upper disc surface can be engaged by a tool for rotating the top and an O-ring located on the under disc surface seals the disc-shaped member to the upper surface of the toilet base. A plug fits within the slot to hide the same. The stem and top can be integrally formed in a single piece or can be made of more than one piece joined together.
