Well you have to buy a mixer that goes behind the wall which will add expense unless you get a faucet with a bridge in front of the wall. The wall will have to be opened up to mount the rough-in, then fixed. Wont be able to do plumbing in the wall if it is an exterior wall in cold climates. I will be doing a wall mount, I figured "heck, its like a shower install, how difficult is that?" Any other expenses? I don't know.

We just did a wall-mounted faucet as well, but with an undermount sink. The faucet was mounted approx 6" above the countertop, I like the look of your set-up; it's exactly what was in my mind. Thanks for sharing, especially the pictures! Most importantly, you will need a good quality faucet. No matter what I do, I'm going with good quality, name brand faucets. Of all the things I don't want to go bad in my house, water-containing items are at the top of the list. After that decision, we chose these particular faucets due to the the length of the spout. How far does your faucet protrude from the wall? Stephemt, I'd like to hear the same answer about your layout. I'm leaning towards an undermount sink like Stephemt's. Does this make a difference? That said, installing wall faucets is a lot more complicated then installing countertop faucets. In our case, we built a small pony wall (open at the bottom) in front of what's an exterior wall. I think I'm into the pony wall -- it makes for a nice ledge. My sink will be placed against an interior wall, but the kitchen is on the opposite side; I can see the pony wall as a way to protect the plumbing /make it accessible -- am I thinking along the right lines? Thinking of function, would you do the pony wall again? If you hire a plumber, you will need to know and communicate the thickness of your finished wall before the rough plumbing is installed. Oh, I'm hiring a plumber. I admire you for DIYing your bathroom, but that's pretty far outside my current skills set. I wouldn't have thought to let the plumber know ahead of time that the wall would be extra-thick -- valuable information! And thanks for the nice, clear shot of your faucet. Definitely helpful! I don't see a need for separate hot and cold handles other than for style reasons. It's just as easy with a single lever to choose either hot or cold. Personal preference. What we have are "click-clack" touch drain plugs (what I called pop-up), we do not have the lever rod-based "pop-up" drain plugs (what I would call pull-up). Okay, I understand the difference now. I've only ever had the rod-behind type and didn't really realize another option existed. Well, not since I lived in my grandparents' old, old house and we had plastic rubber "stoppers" that we placed over the drain. I'm glad to recognize that options exist, but I think I don't care about this detail. Many thanks to all!

Yes, I think you are over thinking this. I also think there's a chance you might be my father in law, so I'm going to answer the question. ;) If you aim the water to hit right at the slope of the drain, you're in the clear. I wouldn't have it hit right on top of the drain because yes, it will splash. Since the basin of the sink is flat, I also think it would splash if it hit the flat basin of the sink. So if I'm reading your comments correctly, you should scootch the sink a skosh back so the water hits right at the slope of the drain. Now I just hope your countertopfabricator cuts the sink hole in the right spot! :)

I have used a vessel sink with a freestanding faucet mounted to the right, and it posed no problem whatsoever with usage. The water flows out toward the center of the sink regardless. Some people even mount their kitchen faucets on the side or in the corner. Most people would install a faucet handle to the right or in the center but never to the left unless you were legitimately left-handed. Most faucets won't even support a left handle installation unless specifically marked as a left-handed faucet. You could learn to use it, but I think even despite holding implements in the right hand, you'll ultimately find a right-handed faucet easier to use. Without photos of your space it is hard to comment, but seems to me that the top-mount will fit better in your space.
