The Coway Bidetmega 200 includes every feature you’d want in a bidet. Choose between round or elongated models to better fit the shape your home toilet. Instead of buying an entire toilet system, the Bidetmega 200 installs directly onto your existing toilet. The bidet includes a dryer—to help save on toilet paper—and has both front and back washing options. Its four-stage cleaning process starts off gentle, increases pressure for a pre-wash, ramps up to full blast during the main wash, and then calms back down during the final rinse. From the control panel, you can adjust the pressure, temperature, direction, or flow of the water. You can even turn on child-friendly mode and turn on the heated seat. Unlike some lower-end models, you’ll need to plug the bidet into an outlet. The included power plug is 47 inches long, so you’ll have a fair amount of slack.
