I need to see the issue and why this happened at all .

" Remove that matching 4” splash to get more room. "

How do you know there is a 4" backsplash? @Franklin

Show a photo. What do you have now? Sometimes the same model is still available.

"Larger size bumps into backspash"

Are you saying that the faucet itself is hitting the backsplash? Or, what happens sometimes, it is the faucet handle that is hitting the backsplash. If it is the faucet handle that is the problem, there are two alternatives. One is to get a faucet where the handle at the hottest water setting is straight up, rather than pushed back toward the backsplash. It is called "forward rotation lever" or "forward only handle". The handle can only go as far as straight up. Delta, Moen, Grohe makes faucets like that, but there are other companies too. The second alternative is that some faucets are made so that the side lever can be turned toward the center. People also really like this arrangement because it prevents wet hands from dripping on the counter when they use the faucet lever.

@wdccruise - the OP said "Need a kitchen sink faucet base that measure around 1.5 inches wide. Larger size bumps into backspash."

The faucets you linked, the Kohler has a 2" faucet base, the Kraus a 2-1/8" faucet base, the Grohe a 2" faucet base.

There is no definition of "faucet base" and that term is not used in any spec sheet. I assumed that the OP mean that there could be no more than 1.5" between the centerline of the faucet (where it enters the hole in the counter) and the backsplash. 2" to 2-1/8" divided by two meets that requirement. I would have used the word "diameter" rather than "wide" to clarify the request.

That is a good point, as are the other questions above - I re-read the OP a couple times to try to discern what the problem is. I associate the phrase "low profile faucet" to have to do with a lower height faucet like the linked Kohler and Grohe ones, but that does not seem to be what the OP is asking about. The OP is too vague to enable us to give advice. I bet the OP is a flyby.

Thanks for all the feedback. We are trying to find a sink faucet that allows us to use the quartzite backsplash you see as the counter in the photo below.. I was told by the installer that the faucet base siting on stone has to be around 1.5 inches in diameter, see pic with blue pen. Looking to find a faucet brand that fits the area whose sizing is similar to the soap dispenser shown which allows for the thicker backsplash. Thanks for your help!

I think you are saying that the hole's diameter is 1.5"? You'll have to make sure that the base of the faucet fits between the edge of the sink and the tile. Another consideration for a tight space, would be to choose a handle that does not pivot bakwards. This link might help you research your options https://faucetboss.com/faucet-hole-sizes/

Also would you remove the sheetrock and adhere stone directly to wall with appropriate to code procedure?

@theresa21: "I think you are saying that the hole's diameter is 1.5"?"

No. She wants to add a backsplash using the countertop material. That's why she wrote, "We are trying to find a sink faucet that allows us to use the quartzite backsplash you see as the counter in the photo below." After she adds the backsplash, she thinks she'll only be able to install a faucet whose base diameter is 1-1/2" or less. She doesn't provide any dimensions such as the distance between the center-line of the hole and the edge of the sink, wall without backsplash, wall with backsplash, or size of the hole. The words "low profile" are misleading.

The mistake she made was installing the sink too far back or installing a sink that is too wide. She should have provided more space between the back of the sink and the wall to accommodate the backsplash and faucet. For example this Delta Linden faucet requires 2-1/2" minimum between the center-line of the faucet and the backsplash.

Laying a tape measure in this picture to understand the depth, the hole and the limited space would be helpful here.

Your best bet is to take your existing faucet into a plumbing supply showroom and asking the salesperson to show you options that will fit. Or you simply go onto Build.com and look at the spec sheets of various faucets to see if the dimensions will work.

I agree that the mistake was in choosing a sink that is too deep front-to-back. The sink's dimensions should have been taken into account when shopping for a sink. It is too late for the OP, but this experience might help someone else reading this thread who has not yet purchased their sink.

I see three possible solutions. One is to install the faucet in the corner (see photo). You'd need to make sure the pull-out is long enough to reach the entire sink. Another is a wall-mount faucet (see photo). This adds the expense of plumbing for the wall-mount, and a wall-mount faucet itself will be more expensive. And the third solution would be to ditch the idea of the quartzite behind the sink.

Take a picture of the whole sink in the counter. I'm wondering why the sink is set back so far.

And to those who said it's her fault if it's set back to far, how do you know it's her fault?

Yes this was not done by me and trying to be proactive with a solution .

We have a quartzite slab BS behind the sink so i totally get the struggle! (we found a faucet to fit but it’s not made anymore) what about something like this? reviews mentioned it was good for a tight fit -

"to those who said it's her fault if it's set back to far, how do you know it's her fault?"

@cpartist - there has only been one comment about setting the sink back too far (not "those" as you put it), and that comment said "The mistake she made was installing the sink too far back OR installing a sink that is too wide." We try to give advice based on info the OP has provided. She hasn't said anyone else made these choices for her. What difference does it make in any case? The sink is installed. And now we are offering as many alternatives as her info allows.

To the OP - a quick search on the Build website did not uncover any kitchen faucets with a diameter (which is what your blue-pen picture seems to point to) of less than 1.5". The standard hole diameter for a kitchen faucet is 1-3/8". You are seeking a faucet body that is only 1/8" larger than the hole for it. If it is even made, it would need an escutcheon for stability. I did see a Signature Faucet "Ocala" that has a faucet body that looks to be 1-3/4" diameter. https://www.build.com/signature-hardware-948533/s1707263?uid=4360309&searchId=KckrjieFUR
