Kohler's most advanced toilet, the compact and streamlined Numi boasts an array of features to meet the needs you never knew you had. For instance, the heated seat lifts when it detects motion and closes automatically when you leave the room. Jets clean your most private areas, and built-in blowers get them dry. In addition to warmers for your feet, there's also a charcoal filter that removes unpleasant odors from the air. Oh, and it's equipped with a speaker that plays music you've saved, or it streams tunes from your smartphone (or any Bluetooth-enabled device). Why sit anywhere else?
