Product Overview

This Wellworth Black Black high-efficiency toilet tank is a perfect match to bowls of the same color in this KOHLER ensemble, furnishing a uniform, modern look to your bathroom. This unit delivers 1.28 GPF, which is a huge improvement over 3.5 Gal. toilets that were commonly installed in American houses in the 1980s and early 1990s. With a canister flush valve and gravity-assisted syphoning, you’ll find that this tank has thrust comparable to that of yesteryear’s inefficient toilets.
  • Class Five flushing technology furnishes leak- and plug-free throughput

  • Outfitted with left-side trip lever
  • Supply line not included
  • Gravity-assisted siphoning action delivers extra flushing oomph
  • Canister flush valve maximizes flush performance and inhibits deterioration and warping
  • Matches up with black black toilet bowls in the KOHLER Wellworth lineup (not included)

  • Releases 1.28 Gal. of water per flush
  • Wellworth toilet bowl (model K-4199) sold separately
  • May qualify for rebates from your municipality or utility provider

After carefully installing this Kohler tank, the gasket between the tank and bowl failed within a couple of weeks so, I've had to purchase a new gasket kit and re-install. I've run out of patience with this brand and now looking forward to replacing the tank and bowl with a different brand.

Rated 5 out of 5 by from Replacement tank. Couldn't stop a leak in my old Kohler tank (K-4620) replaced old tank w/ this K-4636-0 and it fit perfectly. Make sure your Kohler has a 3 bolt pattern at bottom of tank. Easy installation.
