Product Overview

Kohler has the same conservation ideals as you, designing this Wellworth high-efficiency toilet tank in white to provide superb flushing power while using less water. This unit delivers 1.28 gallons per flush, which is a huge improvement over 3.5-gallon toilets that were commonly installed in American houses in the 1980s and early 1990s. Its sleek profile meshes with a coordinated bowl for a complete toilet.

  • Wellworth toilet bowl (model K-4199) sold separately
  • Releases 1.28 gallons of water per flush
  • Canister flush valve maximizes flush performance and inhibits deterioration and warping
  • Gravity-assisted siphoning action delivers extra flushing oomph
  • Class Five flushing technology furnishes leak- and plug-free throughput

  • According to the EPA, a high-efficiency toilet like the Wellworth can reduce a family’s water usage by 20-60 percent, resulting in lower utility bills
  • Matches up with white toilet bowls in the Kohler Wellworth lineup

  • Supply line not included
  • May qualify for rebates from your municipality or utility provider

does this toilet tank fit most toilets?

My toilet is fine but the tank is broken.
Asked by: klgv
I ordered it on line form Home Depot I originally tried to order it from Kohler but they just sent back to where I purchased it. I would say it does not fit ANY toilet. Its shape is unique (smaller than normal)

Yes it will install on the 1.6 gallon base no problem flushing on the other hand may be a bit sticky if the older model did not flush well to begin with.

will 1.28 replace 1.6 gpf

I need a tank. I have a Kohler, model # K-4620DA 1.6 gpf. I don't want to pay hundreds of dollars just for a tank. Will a 1.28 gpf fit my toilet and does it come with all the innards? I can pick it up from Home Depot and what will the cost be? Thank you Ben
Asked by: Buckwheat
Yes, according to the info I have read. It works on my Kohler which was a 1.6gpf.

Class Five flushing on the other hand is based on a perfect plumbing installation. On an older home that has settled, plumbing included, as in my case needs a bit more water to complete the flush. This causes me to hold the lever down until it completes the entire flush. the previous model tank worked when adjusted for maximum water level. I'm probably using more water now than before due to this "New Technology" that goes backwards. John Crapper is rolling over in his grave..........

I love that it does not take as long as my previous toilet to fill and reset and that it is quiet. It is somewhat small (short) but I am short (5'4") so it is perfect. I would not recommend it if you are over 6 feet tall, but it is great for us short people and children.
