Expert Review Analysis

The Kohler K-GP89825 is a genuine 2-inch replacement flapper designed exclusively for the Kohler Portrait one-piece toilet model K-3357. It features a shark-fin design with an adjustable chain and is constructed from premium, corrosion-resistant rubber to ensure durability. This part serves as a direct replacement for several discontinued flapper models, including 88925 and 85655.

✓ Best for: Owners of the Kohler Portrait K-3357 one-piece toilet needing an exact OEM replacement for a worn 2-inch flapper, particularly for models predating 2004 or those with discontinued parts like 88925. It is ideal for routine maintenance to prevent leaks and restoring flush performance in compatible toilets.✗ Not ideal for: Owners of other Kohler one-piece toilets such as the K-3488, or users with Class Five toilets requiring larger 3¼-inch flappers. It is not suitable for general use across multiple toilet brands or models due to its exclusive design.

Pros

✓Constructed from premium-quality rubber that provides enhanced durability and corrosion resistance
✓Includes an adjustable chain mechanism that allows for easy and precise installation adjustments
