I just researched this question myself, so I will try to help here. Each faucet has a different distance and the differences range to 30" or more. I found the best way to tell is find your faucet on a website, click on "more details" or whatever the similar label is on the website and open the tab marked "specifications." Look for the length of reach on the list of specs. If it is not there, open the installation drawings and look at the diagrams. Also, the measurement sometimes includes the part of the hose that stays inside the faucet neck, so subtract that if you need a specific measurement. I think there was one that was 56" and if I remember where I will post again.

We don't find it to be a detriment. We chose our Grohe Ladylux Cafe because it felt good in our hands, and ergonomically seemed like it would work really well (e.g. size-wise, getting inside smaller pots and pans, and the tight corners of our sink). We didn't (still don't) LOVE the look of our faucet (they've since come out with a sleeker version), but for a kitchen workhorse, went with function over form. The need to hold down the spray button wasn't a big factor in that decision.

Nope, I don't wish I had a seperate faucet at all. I like having the choice on one fixture. I know folks have asked me how it is to clean. It is a breeze to clean. It really doesn't get dirty. You control it by the handle for off and on and temp control. Where it sprays and how it sprays is controlled by the part where the water comes out, not on the coil part. The coil part is rigid. It doesn't flop around at all. My sink is standard size for my cab which is 36 inches. I had my sink cab built out three inches so it does stand out. I did that because I have my sink cab in espresso stain and my other cabs are in natural maple stain. I wanted it to look different and stand out like a piece of furnature. It does and the extra three inches gives me much more room under the sink for storing things. BTW, my sink is 8 inches deep. Again, for the most part, standard size now-a-days. I could have had a deeper sink but didn't want one. I am only 5'2" and have found deeper sinks to be very uncomfortable for me to use. Sorry, I don't have the best of pictures to show, but here is/was my unfinished kitchen. You can tell they had just finished installing the granite because the blue tape is everywhere and my undercab lights also hadn't been installed--hence the wires.

Jenny - I like the Kohler Artifacts faucet, because of it’s appearance, the heft, and its 3 spray modes. But it does not come in the brushed nickel finish you want. I am not a fan of brushed nickel, so I have not looked into, or know of, faucets in that finish. Your OP has the word “commercial“ in it. That word says to me that you are talking about a “pre-rinse” style faucet. They are usually tall, so cannot have cabinets above them, just open air. Examples are the Kraus KPF-1602 or Kraus KPF-1612, both a lot of bang for the buck.
