It would be helpful to have a diagram with dimensions--especially around that stairwell area. Assuming you have room to do this safely, I would put the DW right of the sink. It's always preferable to have the DW on the opposite side of the sink from the range. How much space between sink and range in the current plan? I would want my sink centered under the left window, so I'm not staring at the center divider. But I don't know how crowded that makes your sink/range prep zone.

Trash to right of sink, dishwasher to left, so you can use both while standing at the sink. Or, trash pullout under sink itself, to preserve more of cabinet 1 for storage.

Thank you for those thoughts. I just uploaded another image that has the cabinet dimensions and total lengths for the L.

That corner trash cabinet looks terrible. Without a pullout, you are going to be leaning into the trash can to scrape plates. Uncomfortable, and any slight miss puts gunk on your cabinet floor. Personally, I would use a SimpleHuman trash can on the back (sink) side of cabinet 16. Or if you really want your trash hidden, under the sink.

Dishwasher should be based on whether you are left or right handed for rinsing and loading. Personally my dishwashers on the ends of my arms and I have more cabinet space. :-) But if I were to have an electric one, being right handed, I would put to right of sink. Put trash closest to where most of the trash originates to minimize steps. I do not like it inside a cabinet or under the sink and have a tall can with step-on lid opener - hard to toss trash if hands dirty or sticky and have to open a cabinet. Just dump it often to keep smell out, and if you have chicken bones or smelly food trash, etc., take it outside right away in a plastic grocery bag and not even into the kitchen trash. Hope this helps. Try to get solid wood cabinets to eliminate toxic off-gassing from glue in particle board.

Based on your description, it appears that the area adjacent to the stairs is a landing. If that's the case, I wouldn't put anything that obstructs it such as a dishwasher or trash pull-out there. I envision somebody coming up the stairs, rounding the corner, hitting an obstruction such as an open dishwasher door, and falling back.

Take this for what it's worth: I completely demolished my condo kitchen and DIY'd an IKEA one. I strongly recommend you skip the cooktop + oven* and just buy a 30" range. There are so many things you have to do without this unnecessary task: planning, purchasing, demolition, floors, electrical, plumbing, rails, cabinets, drawers, doors, countertop, sink, faucet, disposer, backsplash, dishwasher, microwave/hood, refrigerator, lighting, paint...and for much of the time you won't have a working kitchen. Don't make it any harder than it needs to be! Just leave a 30" opening, make sure the 240 volt outlet is in the correct location, buy the range, plug it in, and shove it into position.

*You would also need two 240-volt circuits, one for each appliance. If you're going induction and looking to save money, Frigidaire has introduced its remarkably inexpensive FCFI3083AS for $1000.

What is the distance between the upper wall (that the range backs to), and the staircase wall (that cabinet 16 backs to)? If you have 8 feet from wall to wall, I would consider making a galley kitchen here, with sink and DW against the staircase. Expand the window upwards if possible to flood the area with light. The more I think about the traffic flow at the stair landing, the more it seems somewhere between annoying and risky to have a person at the sink frequently, right where someone turns from that tight stairwell landing. Maybe "step down" to 18" deep cabinets and countertops at the stairwell, to make landing traffic flow better.

Do you have a picture of the stair situation? I'm having a hard time envisioning it -- is there a door?

@wdccruise appreciate the advice on the range from another DIY-er. We are back and forth on this, so appreciate your perspective. We've always just found the the crack between the range on each side of the countertop accumulates so much gunk, so a continuous counter surface seemed so appealing :)

@hannah absolutely. Here are some extra images and context that will hopefully clarify:

We have a rancher with a center stair down to the basement between the living room and kitchen (the entrance to the stairs is by the sink). Our primary goals for this remodel are 1) to open up line of sight between the living room and kitchen and to greatly increase the amount of kitchen countertop and storage.

We also don't have a formal dining room, so before this remodel, our small living room has been doing double duty as living/dining.

Our (somewhat wacky) plan for the space is to bring down the walls around the stairs to pony height (we've pulled permits--one of the two walls is load-baring) and then put countertop over the left side of the stairs (where there's enough head clearance) to serve as an informal kitchen eating counter.

Original layout was like this:

Planned layout is like this:

@terrib962 our current dishwasher is also our hands :)

@artemis78 happy to hear that under sink is working for you since that seems likely to be what we end up with as well (we also don't end up with food scraps in the trash because of access to municipal compost. Do you have a compost solution that you particularly like?

We don't have a great one, sadly--right now we use a large 1.75 gallon Oxo bin that fits the green waste bags and seems to hold about a day's worth of food waste for our family, so we take that out to the big bin each night. It just sits on the counter next to the sink and people scrape into it throughout the day. We've tried a few countertop bins over the years and I like this one better than most, partly because it's large enough to get us through a full day. We go through periods of also having a backyard compost, which adds a layer of complication since then we have to separate green waste that can go into that from all the other food waste, but the last couple of years we haven't really been maintaining that so that simplifies things. Because we take the food waste out daily, we typically empty the main trash once a week, unless there's something plastic with food waste on it (and even then I sometimes bag that separately and throw it in the big trash bin instead of putting it in the pullout so that I don't have to empty the whole thing).

If you do go the under sink route and aren't doing the plumbing yourself, make sure your plumber knows you plan to do that--we needed a sink with a center drain to make that work (or an offset drain on the opposite side would have been fine too) and our plumber was careful to route the pipes so that we'd have room for the double bins. Our dishwasher's flexible drain does route behind the trash, so it is clipped to the back of the cabinet to make sure it stays clear of the bins.

I have trash under the sink and it has been great - I also have our compost bin there, too. I do have a separate standalone can for returnables as we are in a bottle deposit state, but miving 2/3 of our waste receptacles to under the sink was a huge improvement!
