Tank cracks very easily.
I have had two of these tanks get hairline cracks from top to bottom just by putting the lid on. I put this lid on very carefully. The porcelain seems to be too thin. Koehler did not stand behind the defect with warranty coverage. Very disappointed.

Tank Replacement Was A Breeze
The tank came with all the internal pieces already in place (handle, flush canister, valve, etc). Just required removing old tank with 3 bolts and putting the new tank on (leveled) with 3 new bolts (also included).

Perfect fit!
Replacement tank was a perfect fit, and the fact that it included all the inner working parts was a very nice surprise. Received tank in about a week after order.

Cheap junk
Bought 3 of these. They all started losing water in about 3 years. The canister seal loses resilience because of its cheap construction. The whole system is substandard and not worth half the price. Ridiculously loud flush. Cheap junk.

Quick Flush and Never Clog !
This K-4198 toilet and K4468 tank is great ! It has never clogged and was tested under the same conditions as our previous toilet. Our plumber also installed a magical Kohler seat that closes slowly without slamming. Very Happy

We have three of these toilets in our new home. They are very efficient and never clog.

Hi CB, this is Sarah with Kohler Co. I am very sorry to hear two of your Wellworth toilet tanks cracked when you placed the tank lid in place. This is...
