I currently have this 4260 model toilet. My tank cover has rounded edges. In these pictures the cover looks flat. Can I get a flat tank cover to fit my model, and if so, how do I know which one will fit?

Asked by: Drottsco
If you are needing a tank lid for a 4260 tank you will need to replace the whole tank with a 4266.014 model. We no longer manufacture the lid for the 4260 model.

Rated 5 out of 5 by from toilet in bone color Make sure you get the 2 PIECES as stated before you check out. Had to wait another day for the tank. Installation went well using waxed seal. Also didn' t realize that the seat height s come in different heights.
