When it comes to pot filler faucets, there is no “one size fits all” answer. The height at which you install your pot filler will depend on a few factors, including the height of your stove, the size of your pots and pans, and your personal preference.
In general, pot filler faucets should be installed somewhere between 15 and 20 inches above the stove. This will ensure that the faucet is high enough to fill even your largest pots and pans, but low enough to be within reach.
If you have a particularly high stove, you may want to install your pot filler a bit higher up. And if you tend to use smaller pots and pans, you may be able to get away with installing your pot filler a bit lower down.
Ultimately, the best way to determine the ideal height for your pot filler is to experiment a bit. Install the faucet at various heights and see what works best for you.
