The main thing to consider is the height of your faucet. As long as the prep faucet moves side-to-side, you should be able to get things in and out of the sink easily, but you may not be able to wash or fill larger pots and pans. I chose a lavatory sink and lav faucet for my prep sink. I did this for aesthetic reasons. Everyone tried to discourage me on the sink size, placement, and my choice of faucet. I took lots of time to consider how the sink would be used, the biggest thing I might want to wash, etc. The only problems that I encountered is that lav (and prep sinks) have smaller drains. This meant that I couldn't use a regular strainer basket. Of course the prep faucets may not have sprayer features, but who cares?!!!? If you like the faucet combo you've selected, I can't think of a reason not to go for it. After all, it's YOUR kitchen. (By the way, I have a high-end Delta faucet in an unusual bronze. It did not come with a drain or air gap for the dishwasher. Don't know what color your is, but buying the matching accesories for those two items was exorbitant. Good luck!

It would be very nice, but not necessary. I have two different faucets. Complimentary in design, and same in finish, but very different. Either way is lovely. Ivette vs.

Oh, forgot to tell you...yes, I do like it. It's easy to use and when I'm filling a pot I leave the pot on the counter and just pull out the faucet head and hang it on the pot edge. I then let it fill...hands free! This is especially handy when I'm filling the 5-gallon bucket for the fish tank. Once that bucket is full, it's too heavy (for me) to lift it out of a sink and then over. It's so much easier to put the bucket on the counter, fill it, and then just ease it off the counter. I have a confession to make, I think I actually like the pull out functionality better than the pull down...I know, it flies in the face of the trend and opinions of most people here... Don't get me wrong, I really like my Vinnata and it works great for the Cleanup Sink; but for prepping, I find the pull out more useful and easier to use. I'm glad I have one of each...I have all the pros of each and those pros counteract the negatives of the other.

Hansgrohe makes good faucets. Huge faucets. :) As far as prep goes, remember the faucets we all grew up with? Low, tiny, worked for mom just fine. I'd get the measurements off the web and go stand at my current sink with a tape measure and figure out where it's different from what I have and if it would bee good different, bad different, or indifferent different.
