A friend of mine has a similar layout. I know you were smart enough to plan for spacers near the DW so it can open, but make sure you post a reminder on the wall when you start. My friend did her own design too, and had the spacer, but when her contractor put everything in it got overlooked in the chaos and wasn't noticed until the counters were in. They also forgot to put the end panel on the peninsula before templating, so they could not add the filler back since the counter was already foo short (no overhang). Now for some suggestions. I have no expertise other than what I learned here and through my own remodel still in progress, but more ideas are always better! The peninsula cabinet next to the DW will be hard to access from the chair side. It looks like you have 24 inches or so overhang based on having a chair on the end. You will have to crawl under there to access that cabinet each time. I know if that we're my cabinet it wouldn't be too long before I stopped crawling under there and forgot what was living in it. I would consider adding spacers to be able to open the drawers on the kitchen side (obviously not when the DW is open), or make it a blind corner, or close that section off on both sides and make it a blind corner that opens to the hair side next to the wall, where the overhang is manageable. For the Advantium, what about sliding the fridge to the right and removing that tall cabinet (pantry?). Then put a 30 inch cabinet where the small one is now. You could put the OTR model there over some countertop, or move up to a built in wall oven Advantium. Use the bottom for a pantry, there are great base cabinet pantry systems, or do 2 smaller short pull outs side by side. The built in models will allow a 9x13 dish to rotate inside, where the OTR model will not. I have a small space too, and I ultimately decided that if I was going to spend the money for an Advantium, I wanted one that could function as a full second oven, because if I ended up loving it I would be kicking myself every day for not getting the built in. That was a hard 30 inches of space to give up, won't know until May if it was worth it :-) I think you have done a good job so far thinking of what you need. My kitchen has some challenges too, and I know those trade offs (like 30 in drawers instead of space between the sink and range) are hard and not made lightly.

Yes, it would be a chandelier. :) So "to scale" would just disregard the length calculation then? Use: A standard 8-foot ceiling requires a chandelier that is 20-24 inches in height. Choose a chandelier whose width is at least half the smallest diameter of your table, and no larger than the smallest diameter of your table less 12". In our case the width should be between 20." and 29".

Thank you all for the feedback! While the tile to the sides of the drain could’ve been set better, it sounds like it’s not too egregious nor does it look off so I think I’ll stop obsessing over it and not fight this battle. :) @cpartist your photo was really helpful and I like the way it looks! It helps me feel more at peace with the drain size. @Mike Blasko thank you for educating me on the joys of linear drain maintenance. 🤪 My husband chose the linear drain so perhaps I’ll share this info with him! @Brad Smith yes, I agree with you that I think a light colored grout will be an easier and cheaper solution. :) @Charlie Barnes heh my apologies for the confusion. We were supposed to install two same-sized (36”) linear drains, one in master and one in guest. We somehow got all these different sizes but the Guest bath got the smaller linear drain that looks worse off vs the master. :) it’s def in the correct location — just not the intended size for the width of the shower.

Do you really need more light over the island? Some people have enough recessed lighting that drop-down isn't necessary. Some people get balloons the size of the fixture they are considering and hang them down to get a feel for the space. You can also read up on standard formulas for sizing like from this article: https://www.lumens.com/how-tos-and-advice/how-to-choose-the-right-size-ceiling-light.html
