Kohler K-4512 Toilet

I highly recommend this toilet.  It's a low flush (1.6 GPF), round front toilet that swallowed this pile of steaming stuff in one flush and didn't even live a skidmark.  Sadly, it's discontinued.

I've never had it clog on me but due to the pain drugs my wife takes, her stool is Type 2 at best and those rock-hard sausages occasionally clog it. But I still recommend the toilet, she's plugged up toilets around the world.
