I kind of get it--you want the water to be able to go straight down into the drain, right? Does your faucet swivel? Or have a pullout? I think that would take care of it for when you want that. One of the things I really like about the faucet not running straight down into the drain is that the drain isn't covered when I set a bowl down to fill or something.

Imagine you are a right-handed person, scrubbing a baked-on cookie sheet. You're holding the cookie sheet tipped up with your left hand, and scraping and scrubbing toward the drain -- easily done because the drain is in the right rear corner of your sink! If it were in the center, the cookie sheet would more likely cover the drain -- you wouldn't be able to set it down flat to scrub without covering that drain -- a colander with vegetables would have to straddle that center drain instead of sitting securely in the bottom of the sink pitched toward the right rear center. The crusty pan that is soaking in your sink does not cover the drain that you need to quickly rinse something else. It's just better design. If you are a left-handed person, you might want the drain in the left corner. Lynn

Thanks, sabjimata, akchicago, cilantro, and pinch me. I think I am going to stick with the right-side installation and center my faucet, even though it means the stream will never reach my drain. Anyone who wants to scream "Nooooooo!" at this point, please feel free... (notwithstanding pinch me's great point about marching to my own drummer, which can never be said enough... thank you, pinch me!) akchicago, your points about pull-out/pull-down sprayers vs. side sprayers are all right on the money. I was actually aware of the disadvantages of side sprayers -- thanks to this site -- and bought one anyway. Why? Because when the end of the faucet's nozzle is a spray head, and its spout is harboring a spray hose, the whole thing becomes quite beefy and contemporary-looking, and my husband didn't think it would look right in our 125-year-old kitchen. So form won over function this round, and I am okay with that... though I'm sure to have the occasional pull-out envy when my thumb gets sore from pushing down on that little button... Still trying to decide if it's okay to cheat the faucet an inch or two left of center (to align with center of window pair), now that I will have the drain on the right. I mean, if the stream's not going to hit the drain anyway, does it matter where it hits? Or is there a reason to keep it as close to the drain as possible, even if it's no cigar? Thoughts?

Our sink is not centered under the window, either. Our faucet is configured in a way that is tricky because the faucet's base is "centered" relative to the spout (which is to the left) and the handle (which is attached to the right). It's hard to explain..If you look at the pictures below, you can see what I mean. We had it mounted so that the stream from the spout flows into the drain hole of the sink. Our sink's drain hole is in the center. This faucet placement ended up to the right of center relative to the length (back edge) of the sink. We had the soap dispenser mounted to the left of the faucet to help counter balance the faucet's placement. We are right handed and the soap on the left is no problem at all. As far as the total overall look, I am happy with how things worked out. The fact that the sink & faucet are not in the center of the window does not bother me at all. Have you made any sort of mock up faucet, handle, water filter & air switch? I used a small water bottle with a piece of cardboard taped to it (cut to the approx. size, shape & height of my faucet) to simulate the faucet. You can also make a rough mock up of a water filter with anything around the house. You can put them in various placement scenarios and stand back and see how you like it. If you have the faucet & filter at your home already, then someone can hold them in place for a few minutes while you see if you like it. But, I like the mock up items to be around for a little while (more than a minute) so I can get a better feel for their placement.
