Its horrible unless you have 3’ of prep space between the two.

I have about 30" between my prep sink and range. Your plan is better as a potfiller, but less good for vegetable prepping and stuff. If there is enough room for the way you cook, I think it's actually okay.

But...12" is pretty small. Can you really drain pasta into it or whatever you might need to use it for?

The range next to the window is a bigger issue for me. Unless the hood is much larger, you're going to get schmutz on the window. I'd put a cabinet between the window and range for better hood function. That'll also give you more prep space by the sink.

But that'll make it look weird. So I dunno. :)

@Emily R. I was actually thinking if this layout turned out to be less than ideal (which it is appearing to be), I would do just that. I originally had it like this because it would give me a 5th wall cabinet and I could always use more of those.

@Fori The hood I planned was 30" to match the 30" range, but it sounds like it's not going to be enough to keep the window clean? If I shift it right like what Emily R. proposed, it sounds like I will get a little more space away from the window.

IMO a sink next to the range is perfect and a lot more pratical than a stupid pot filler IMO. But you do need a landing space on that side of the range and I would need to see the whole kitchen layout .BTW forget work staion sinks and for sure the grids in the bottom of any prep sink those grids get gross and just one more thing to clean . The reason i like the sink near the range is it provides a nice spot to fill pots and empty boiling water too. Just move the sink to the other side it does not need to be under a window I aneed to know where your fridge is and if you post a to scale plan here with all windows , doorways , where those doorways lead , plumbing and gas lines if you can't move them easiliy all sizes of appliances and all measurements clearly marked you will get lots of free advice.

Usually a hood is helped out by the cabinets flanking it because they help funnel the fumes in--if there aren't any (or sometimes even if there are), it's a good idea to have a larger hood.

I do think you can lay out that back wall better, perhaps like Emily suggested. And do keep the sink near the range. Just maybe not quite as close. :)

Functionally you are almost there. Getting it to look good once we reshuffle your cabinets and appliances...that's the tricky part. Green cabinets is an excellent part of looking good.

The window is small and awkwardly placed. I would lose it and move the range to the right, allowing for three upper cabinets on each side of the range. That would also provide better distance between the prep sink and the range. You might also consider a butcher block countertop (rather than quartz or granite) just for the section with the prep sink. I had one next to my range in my last house, and I regret that I didn't put one in my current home. So, so handy right next to the range. I'm including a pic so you can see what I mean, although mine didn't have a prep sink in it. The rest of my countertops were granite.

@Patricia Colwell Consulting Do you know of a good tool that can generate a good to scale plan? Using the home.by.me tool, I just manually added some measurements here, but I'm not 100% confident on the accuracy. The cabinet layout is almost exactly like the existing layout (to minimize changes there) except the range is moved to where the dishwasher was located and the sink by the window was a larger full-sized 30" sink. Since the island will house the main sink, the old sink by the window will no longer be needed, and my goal was to take advantage of the existing plumbing hook-up there by putting in a small prep sink. The new range location basically takes over the existing dishwasher footprint (with an additional 6" taken from the left in order to keep all the cabinets on the right side).

@Dawn Agreed that the window is small and awkward. It basically looks into the neighbors' trampoline, however I'm not sure if I can get HOA approval for removing it altogether. Reading the HOA aesthetic rules, I think they prohibit large swatches of walls without windows, I'm still trying to read through the code book to see what is and isn't allowed, but I keep falling asleep :)

How much do you love the pantry? I'd do cabinets there to balance out that side of the window and just slide that range down. Chunk of cabinets....sink/window...chunk of cabinets....hood.range....chunk of cabinets.

Never lose a window, no matter how many trampolines it overlooks!

@Fori Agreed, I'm playing around with some layouts where I do away with the pantry. My friend is advising getting rid of the prep sink altogether since the current range/fridge/sink setup has a good triangle workspace already so I'm doing some soul searching on that as well.

A friend suggested adding a window (which might be an easier sell with the HOA) to flank the hood so we worked this up:

looks nice but 30" is way too small. Expecially w/that large island and tall cabinets.

you have to think about proportion. If you had a low ceiling, tiny kitchen, 30" would be fine.

with yours, it's going to look really small.

go for the 36"

I'd rather have a larger stove than 2 windows.

and ditch the large hex tile backsplash for the same reason.
