Kohler's Numi is arguably the most-advanced toilet out there.

Starting at $6,097, the Numi is clearly targeted at the luxury market. It's completely automated. The touchscreen remote means you never have to touch the toilet with your hands.

Other features include a heated seat, integrated bidet, color-changing lights, controls for music, and even a heater for your feet.

Business Insider was recently able to take the Numi for a whirl.
