Where can someone buy a handle for this brand of commode? I live in Bowling Green, KY.

Google plumbing supplies and add your zip code. I guess your picture didn't come through. I know Kentucky has a Home Depot or Loews near you, and plenty of plumbing supply houses, and you could always contact the manufacturer of your commode directly.

You can Google that also.

As mentioned above comment, you can buy generic handle for your toilet in big box stores, like HD or Lowe's. I would take the old handle with me, to make sure I am buying the right one.

Hope that helps
