Toilet works great, and doesn't splash at all. Would buy from Kohler again

No splashing

Kohler has been my standard specification product line for 40 years

This toilet is really nice, but it's not as quiet as I would have hoped. It is a faster flush, but for a brief moment it's noisier then the 30 year old toilet it replaced.  Also, the "white" is not a white white, almost an off white, but it was called white.

Comfort Height is a winner

I'm a contractor have been using these for years. Old suppliers years ago from Wholesale Plumbing lead me down this road and man did they know what they were talking about.
Just installed two last week again and had a little trouble the porcelain was missing in a little stop in the back and the flush valve was broken.
Called Build with Ferguson and instantly they had another on the way. Then I called Kohler and they overnighted the flush valve. 
"Crap happens" no one's perfect but it's the professionalism of the two companies involved that had my back and you can bet I'll be shopping with them forever,
Great job....love, love, love this company and all their products.

CLOSET ROCKS!!!

When I bought my house, it came with another brand of toilets that all needed plunged or fiddled with on a several-times-a-week basis. We had multiple plumbers check them out, cleaned, drain-snaked, but it never fixed the ongoing problems. After replacing one with a Kohler Wellworth toilet, I have not had to plunge it once. 

Easy to install. Easy to use. Flushes like a champ, every time. That's all I ever wanted from a toilet.

Quality is Standard

Fantastic. Right seat height, easy flush, good color

Fantastic

Disappointing the toilet doesn’t come with a toilet seat

Nice
