I'm not sure if the 2013 model's sink/faucet is any different, but I was able to use a standard 4" 2-hole bar faucet from Home Depot in place of the existing faucet:
It's an American Standard "Cadet", model 2475F - it takes the standard 1/2" supply connections, it literally took just a few minutes to swap it in place. It was $68 here in Canada, the stores I checked here didn't have a lot of selection so I couldn't get too picky without ordering something online.
Some people have swapped a detachable sprayer-type faucet in place, I wanted to but couldn't find one I liked that was in our price range (didn't want to spend $150 on a faucet!). I will note that sometimes there is splashback from the sink with this faucet being so high, but the convenience of washing pots/larger items and filling tall water bottles outweighs the drawback.
Note that if you have a swing-down galley like ours, to measure the clearance from the sink down to the floor when folded beforehand
We still have 2-3" of clearance to the floor, and we place a wash basin under the sink while travelling for two reasons: 1) catch any residual water leaking from the faucet, and 2) prevent anything stored on the floor from sliding into the faucet and bending/breaking it.
