Kohler K-3978 Reviews

Rated 5 out of 5 by from Kohler Wellworth Toilet... Well Worth It! I had first seen the Kohler Wellworth toilet (Apparently the newer version) in a newly constructed Mariott Hotel. I was pleasantly surprised by the size and shape of the toilet. The flush action took everything my family threw at it, as well as still beng a quiet flush. As I had some basis on other toilets, it was time to buy a replacement for the second bathroom, but I did not want to spend $500 doing so. I had decided to get the "New" Wellworth. So here we are, it looks great, performs great, and I was still left with cash in my pocket. Good Job Kohler!

Why is there a ring around the inside of the toilet, it feels rough.

I suggest contacting Kohler for this question. Their phone number is 18004564537.
