Can you rip off the drywall and run water to that location from a basement or attic? It won't be cheap. And it's a doodad that doesn't see a lot of use beyond the initial novelty stage. Some municipalities also prohibit them because there is no drain below, so check with yours to see if it's one of them.

The basement is unfinished, I called a plumber just now, he states he can do it.
There will be some drywall repair needed but we will put a backsplash over anyway.

I too wanted a potfiller in my new kitchen. THen I worried that what if I started to fill a pot, walked away and forgot to turn the water off.
No pot filler for me - I get distracted too easily.
I have had the laundry tub overfill a few times - the phone rang, or I was filling it and then started doing something else while I was waiting. What a MESS>....

I had a very small kitchen and used my pot filler *every day* when I lived in New Orleans. It surely was a luxury doo-dad, but to just run a small stream of water into the gumbo pot? Heaven. And on non gumbo days, I used it to fill the coffee pot, etc. That said, I didn't put one in my new kitchen because it is two straight runs rathern than the old U shape I had before. It seemed odd to have one immediately next to my prep sink tap this time. My mother-in-law did overfill a pot once, which was a pain...took a day or so to dry out that burner enough for it to relight.
