Centered.

I would choose the sink off centered otherwise you will either end up water on the floor or rinse the dish then put it on the counter close to the DW then put it in the dishwasher (double the effort of a task you do few times a day).

You can get kitchen windows that open like a sliding glass door. A pair of them could be installed so the left one slides to the left and the right one slides to the right opening two spaces in the middle directly over a double sink.

If you put a short peninsula on one or both sides of your sink, you could put your dishwasher in at a right angle to your sink and have a bit more counters pace.

You could put a narrower peninsula on the living room side of the peninsula without seating on the living room side. If you don't put a peninsula left of the sink, you could put an "L" shaped countertop left of the refrigerator with a corner pantry and have countertop space beside the refrigerator ... a good thing.

You might want to at least consider putting your dining room where the den is shown and enlarging the living room rather than having a separate den.

Thanks suezbell. yes if money was no object, I'd move the dining room to where the den was but I'm trying to avoid it because the den's fireplace and TV insert was just done 3 years ago when we moved in, not realizing it should have been the dining room. It currently has a horizontal linear fireplace and if that room was a dining room, I'd have to raise the fireplace so it's not so close to the floor (so can be viewed at eye level when seating).

Having the dishwasher far from the sink would be a major inconvenience. I would do the second arrangement but with the dishwasher on the left. I would also do a rolling cabinet instead of the peninsula. The table seating and the counter seating look too crowded.

Just curious D M, what make you choose to have the dishwasher on the left? I tend to put it on the side where I am most comfortable. I am right handed and it seems to make me favor to work from left to right. I find rinsing then placing the dishes in the dishwasher that is on my right makes it easier for me. Maybe if my dishwasher was on the right, I would quickly get comfortable to work from right to left.

I am also right handed. I hold the dish in my left hand, brush it with the brush in my right hand, and place it in the dishwasher with my left hand. It keeps all the dirty dishes on the left. My dish drainer is on the right so I don't cross over it with the dirty dishes.

Thank you for your comments. I thought I'd share a change of layout plans that I'm pondering considering I didn't like either option with sink in the bay window/dishwasher layout. Spoke to the contractor and we think it's easier to leave the sink where it is, widen the window above it to be the pass thru awning window, widen the current U shape, leave the bay window as is and the 'eat in' kitchen table area. So I'll be down a dining room but that's ok, it's only a few times per year MAYBE that I entertain and need more space. I can put up a temporary dining table elsewhere (or switch over the den to dining room in the future) or make that circular table an extendable to an oval one. I may add a built in bench to the bay window now or down the road.

In this layout, it's a little awkward as to what to put in the niche where the pantry is in my drawing below. It's not full height in there and it's currently where I have a sideboard but with my dining room no longer being there after the reno, it should be something else. Pantry cupboards, maybe a little desk with open shelves above? maybe a beverage/coffee station with mini fridge. I know it's a little awkward having the pantry outside the kitchen. That's the only thing that bugs me about this layout.

Other option is to put the pantry to the right of the fridge. In my current kitchen this is where there is a desk and open upper shelves that definitely needs to go. It's where all the 'junk' goes like recipe books, telephone, pet food, meds, etc. so I'm drawn to putting lowers and uppers there to hide all the stuff. But it also makes sense to make this the pantry area so it's more accessible than having to walk around the penisula when prepping.

So that's the dilemma/question...where to put the pantry. And what to use that niche for. Note, that niche does have a direct sightline to front door so people will see it when they walk in the front door. The area by fridge is hidden from view facing back of house

Thanks in advance.

Thanks D M for the suggestion of a rolling cabinet but the penisula would hide a floor directional change. The dashed line in my drawing along the 3 ft (expanding to 40 inch) between fridge and penisula shows where the hardwood floor direction change will be visible. The floors across back of house go from side to side but the hardwood floors in dining/living/foyer/office all go from front to back. So to keep my hardwood floors, the penisula is covering up most of the flooring transition (and where there is no hardwood where the wall is being removed). It's a challenging reno for sure.

I agree Chispa, I don't care what side the dishwasher is on, just close to the sink is ideal.

@Lorrie S We are redesigning our kitchen and trying to decide if we put the sink in the bay window off center to have the dishwasher next to it and curious what you decided. If you used the bay window for the sink/dishwasher, are you willing to share photos? Thanks!!
