There's this type of thing where the sprayer is on the worktop but the faucet is wall mounted .

Or this which is v. traditional.

Karen: Very nice! Thanks. Who makes that traditional set up in the pic you posted?

I have a wall mount faucet with side spray--I think its the same one as the second link Karen posted above. It's manufactured by Harrington Brass--not a company I had heard much about, but I've been happy with the faucet. There are a few other options--Herbeau makes a few, and KWC makes one more along the lines of a commercial faucet. Here's a picture of my kitchen, and I've posted a link to the Quality Bath website where you can see a few other options. If none of the options strike you, I think some people make do without a side spray by going with one of those longer reach wall mount faucets with a joint in the middle (Chicago Faucets made/makes one).

Those big farmhouse sinks have a lot of surface to clean, so the side spray definitely is handy. (and no, the cord hanging into the sink hasn't been a problem for me!)

Oops--sorry, I didn't post the picture I meant to. Here is a picture that actually shows the sprayer... :)

I'm waiting for someone to invent a retractable cord that goes back into the wall! Why hasn't that happened yet?

I opted for the long spout, with no sprayer. Yeah--I kind of miss the spray. But ah well. It was a design choice. I splash the water around with a glass, or a sponge, and I stick my hands in the sink to wipe up. It's not a big deal. Even though I've never been fond of touching sink gook.

I'm looking for one of those attachment sprayers for the faucet tip, but so far I haven't found one that has the right look. I want metal, not plastic. And I don't want an aerator, b/c I don't want to lose water pressure.

Elements Of Design also makes a wall mount faucet w/sprayer

we had the chicago faucet with articulating arm over a shaw's 30" and there was no problem reaching all the corners of the sink to clean it.

Yes, it's the same one in KLB 200's kitchen made by Harrington brassworks.

If you Google image search, using the words wall mounted faucet sprayer then you'll see it on another site. Prices start at $865.80, but ths wouldn't let me post the link.

But I see they are considerably less expensive on KLB's link :)
