Does the spout end of the pot filler have a bubbler or anything screwed to the end? If so, you can remove it and take it to a plumbing supply store to get a hose adapter that fits (it's better to take yours in than measuring it yourself because the threads and size both need to be correct). When you use the hose, be careful not to leave the open end submerged or the liquid can siphon back into the hose and potentially pollute the water in your system. If that won't work, there are also hoses that just slide over a faucet. They aren't as good a seal, so you'd want to put a big pot underneath, and a lot of towels all over, in case it fails, though it probably won't. This kind is meant for shampooing, but if it doesn't have enough flow, you could remove the shower head: http://www.amazon.com/LASCO-08-2180-Faucet-Spouts-Rubber/dp/B006054W1C

We have one. We bought a finished new construction house, and the builder put it in. We've lived in this house for 6 months now. Honestly, it's taken some getting used to - I was so accustomed to going to the sink for water. If you do alot of cooking, I think it's a neat gadget. I find myself using it more. The only thing is that I prefer filtered water (our town water taste of chlorine, IMO). We have an undercounter water filter, so if I'm boiling tea bags, etc., I tend to use the filtered water from the kitchen faucet. However, earlier this week I canned some tomatoes, and that pot filler was awesome. I put my big canner on the range and filled it up while doing a few other things around the kitchen. Our previous house had a pull-out faucet, so to fill the canner up, I'd put it on the counter top (b/c it's too big for the sink) and would pull the faucet over and fill it up, then have to lift it to the sink. The pot filler was much, much easier, although, I did still have to lift it when I was done to carry it over to the sink to pour out. Could I live without it? Absolutely, but for some tasks, it's really handy. It's more of a conversation piece than anything because alot of people (at least in our area) have never seen one. BTW, we have a Brizo one that does NOT have the swing joint (looks like all of their current models do). Having a joint would be handy, but I don't think not having is a big deal. We have a 5 burner Thermador cooktop under it, and if I have a big pot on the center burner, then it will swing over that just fine.

When I read your written description, it seemed like the 30" would get you extra storage cabs which was a concern of yours, but after seeing the visual, you will have plenty of other cabs and counter space. The 36" wide is so nice to use (ours is actually 37.5" wide). There is more room between the burners and ours actually has a griddle as well. Our old stove used to feel crowded up top. Our range has an oven and another next to it that is much smaller that is for cookie sheets. The main oven in our range is a little small, so we got a separate wall oven. This way, with a small item, we use the small oven. Luckily that was in our plan before we discovered our problems hooking up to propane (not approved yet or in the near future) so we are very grateful to have the second oven to use. Having a second separate unit is great because if you ever have one fail, you are not stuck. Of course, you can do a 36" cooktop with separate 30" oven below. That is one way to get duel fuel, if applicable, and not have too large an oven for when you cook smaller things. I'd skip the potfller, because that only helps at the fill stage and the more important stage is when it has boiling water and another pound added to it (the pasta itself) and it needs draining. I'd make sure your prep faucet is tall enough for your pasta pot or there was a pull down/pull out feature to the faucet. I'd also opt for a good size prep sink because you have counterspace to spare. You want it large enough to hold your largest colander. I sometimes see very small ones and wonder how useful they are. It would be great to put the filtered drinking water faucet by the prep sink since that is closest to the seating (if you don't have drinking water from your fridge). I'd also move the drainboard on the cleanup sink to the other side so that the prep side is on the range side if you ever have large batches of produce that can be put there. BTW - our new (vintage) sink has an attached drainboard and so we don't use the basket type dish drainer you are showing in your layout any longer. I love how it looks neater and there used to be some stuff that went in the drying rack and never seemed to come out. I lay any wet stuff on the drainboard itself and put it away soon after. Our new dw cleans better, so we don't have quite as much to wash by hand. YMMV

Pot fillers only provide cold water, right? I have never had one so my apologies if I have that wrong. If that's true I would eliminate a pot filler as I would want to be able to wash my hands with warm water at the prep sink. Gooseneck with no pull out would be fine, I'm sure, but maybe harder to fill big pots if you want to be able to do that Pull out seems like the winner to me. I think if you buy a good one it will retract and dock pretty smoothly for you. Bonus option: kohler karbon. $$$$ and some don't care for the look, but this seems to have all the function you want and they get good reviews here.
