Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.If you have some experience with faucet repair you can probably fix this. I'll need to know the brand and model of both faucets if you want specific instructions. You'll also need that to get parts. If you don't know postings a picture of each here might help me to identify them.You can post a picture here by clicking on the paper clip icon in the tool bar at the top of this dialogue box. You can only post from a PC or a Mac not a phone or a tablet. If that doesn’t work for you then you can upload a pic to a file sharing service like Google pics or Dropbox. Then post the “share” link to your picture here or you can email the pic to customer service but the last option can take quite a while to get to me.

That looks like an old model and if the valve in the wall is the one I think it is fixing this is best left to a plumber. What about the sink faucet?
I don't recognize either one. They're not a current model but that doesn't mean you can't get parts. What I'd suggest is that you go to a plumbing supply house that sells Kohler (one with a showroom would be best) and bring the pictures with you. They should be able to identify the valves and the parts needed to fix them.
But I suspect the shower valve is a Niedecken model. If that's the case then repairing it is best left to a plumber. The sink faucet might be some thing you can do once you get the parts but if you're going to get a plumber to fix the shower then fixing the sink won't take him much longer.
