Our 3D printing process and lenticular lens produce vivid three dimensional images with amazing depth and clarity. This 3D toilet seat shows a sea turtle on the top of the lid. The hinges are non tarnish chromed metal hinges and match most bathroom fixtures. The seat is round, fitting standard toilet bowls that measure 16.5 inches from the front of the bowl to the center of the mounting holes at the back of the bowl. The seat comes complete with mounting bolts, nuts and washers to ensure easy installation and a tight fit.
