Identifying Your Toilet Model

Identifying Your Toilet Model

Model Number Location Overview

  • Toilet model numbers are located in a variety of places on the product.
  • One-piece toilet: The model number is located inside the tank.
  • Two-piece toilet: Model numbers are found inside the tank and the bowl, and are specific for those parts of the toilet. A model number also identifies the toilet as a combined product, but this is not located on the toilet itself.
  • The tank lid for both one-piece and two-piece toilets includes a part number that identifies the lid.

Tank Model Numbers

  • The model number is located inside the tank, either molded into the china or stamped with blue or black ink.
  • The model number consists of four digits and may include a K prefix.
  • In some cases, the model number is preceded by 97. For example, 974166 contains the model number 4166.
  • One-piece toilet: The number inside the tank is the primary toilet model number.
  • Two-piece toilet: The number inside the tank is specifically for the tank (the bowl has its own model number).

Bowl Model Numbers (Two-Piece Toilets Only)

  • The bowl of a two-piece toilet has the model number molded into the china on the underside of the bowl flange.
  • The number on the bowl is specifically for the bowl (the tank has its own model number).

Tank Lid Part Numbers

  • The toilet tank lid also contains a number either molded into the china or stamped with blue or black ink.

Difficulty Identifying Your Model

Residue

  • Model numbers in older toilets may be hard to read due to mineral or bacterial growth within the tank.
  • Rub the area to remove residue. Refer to care and cleaning for vitreous china toilets and bidets on kohler.com/clean.

Tank Liners

  • In some KOHLER tanks, an Insuliner® tank liner may be installed, covering the model number.
  • Record the part number of the toilet tank lid and contact the Customer Care Center at 1-800-4KOHLER for assistance.
