Structure of a Kohler Model Number
- Model numbers for KOHLER products contain a base number, followed by a dash, and series of letters and numbers.
- KOHLER model numbers have a "K" in front of the base number. The "K" may not be included on certain product labels and when stamped onto the product itself.
- Letters or numbers following the base number represent a series, style, or variation. For example, "RA" means right-hand trip lever for a toilet or right-hand drain for a bath
- Letters or numbers following the series/style/variation indicate the product color or finish. For example, "0" is the color code for a white fixture such as a toilet, and "CP" signifies a polished chrome finish for a faucet.
- Letters at the end, after the color/finish, designate the product generation. A first-generation model will have "AA" and the evolution of the product will supersede as "AB" or "AC" or "BA" etc.
Structure of a Serial Number
- Serial numbers for KOHLER and STERLING products are usually 8 to 11 characters long, most commonly 9 characters long.
- Most serial numbers start with the letter “S” and the remaining characters will be alpha and/or numeric
- The serial numbers for Steam Generators and DTV start with any alpha or numeric character.
- A serial number does not contain any dashes or hyphens.
