- 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
