Kohler Toilet Tank Reference Guide

Kohler Toilets and Tank Parts Specifications

Every Kohler toilet has a unique number marked under the lid or inside the tank. These numbers begin with "K-" and are stamped directly into the porcelain. In some cases there is a product sheet taped under the lid from the factory.

To use the listing below, please have your Kohler toilet's "K-" number ready.
