Customize your bathroom retreat. The Ditto toilet seat is our favorite in Kohler's line of Artful Toilet Seats. For both elongated and round toilets, the series adds a bit of spice to your bathroom. Semi-custom products like this are catching on, allowing consumers more options when decorating their homes. We like the understated print of Ditto, but there are other options, too, like the vibrant striped "Suprise".
