Two dolphins jumping on the top of the lid of this round 3D seat with a deep blue edge and ring This seat has a regular edge, with the seat ring slightly exposed around the lid of the seat when the lid is down. The seat is elongated, fitting toilets that measure 16.5 inches from the front of the bowl to the center of the mounting holes at the back of the bowl. It comes complete with mounting bolts, nuts, and washers to ensure easy installation and a tight fit. Our unique printing process creates vivid three-dimensional images. However, since the human eye is more discerning than a camera lens, these photos may appear slightly out of focus on your computer screen. The actual picture has amazing depth and clarity. Our seats fit most U.S. toilets. But please check the diagram and measurements to make sure you get the correct seat for your toilet. We are unable to restock seats if the seat you order does not fit your toilet.
