Well the towel is hiding the style but judging from the cab next to it is is just a simple white shaker cabinet with either a white laminate or a white painted wooden top. Once you have your sink size then just get a shaker style sink cabinet and put a white top on it. It's a simple style that any cabinet manufacturer would have. You might even be able to pick one off the shelf at a big box store depending on the size. They trimmed it out with the interesting towel bar but basically a box is a box.

I agree that mounting the faucet in the corner will be more useful. We mounted our prep sink faucet in a corner as well and, in our case, it works especially well b/c: (1) We have seating on the peninsula - so it puts the faucet farther away from someone sitting at the peninsula behind the sink (and so reduces the chances of splashing the seated person) (2) Corner sinks are usually mounted further back - so it makes it easier to reach the faucet. Grid...good idea to have a grid to raise the bottom of the sink. It's also nice to be able to drain pasta w/o the backwash of the water into the colander, provides a flat surface instead of a sloping surface for items in the sink, items in the sink (dishes or food) will not block the flow of water down the drain so it's easier to rinse the sink, etc. About person height vs sink depth...this is one of the times that shorter is better! Deep sinks are actually more of an issue for tall people than short people. Tall people have to reach even further down to get to the bottom of the sink...so shorter is better!

What are the dimensions of the proposed laundry room? Are you consulting professional designers? (I ask because of your question about doing an island in the master closet which is clearly not wide enough to accommodate an island. At least 11 feet in width is the rule of thumb for doing a small island in a kitchen. Hanging space requires almost as much room as base cabinets require. I.e., 24" is the minimum closet depth vs. base cabinets that are 24" deep + 1.5-2.0" countertop overhang.) How much free space will you have in front of the washer & dryer? 48" is the usually recommended amount of space that is needed to comfortably work in the space. How wide is the door opening? Wide enough to easily get through with loaded baskets of laundry? To move the machines into the rooms. Is there enough space for almost inevitable repairs to be made? I'll echo what others have said; the master closet is large. IMO, a house that has a 'Master Closet' the size of a small bedroom should have more than a cubbyhole for a laundry. Better to have as much info as you can get ahead of a project rather than have regrets after it is done.

Sorry this post got overlooked. I am seeing a very long kitchen. Do you have the total length written anywhere? I also see you are removing 103" of wall going into the dining room. You say you are removing the wall between the kitchen and the 18 x 10 space, too. But the bathroom is part of that area, so the wall has to stay for the bathroom, right? Given that a bank of windows appears to start right after the bathroom, it seems that the only way to expand the bathroom is toward the left, right? I would expand it three feet out - enough that a tub/shower combo can be put on the upper wall of the bathroom with a 2 ft wide linen closet next to it. That makes the bathroom spacious. Then along the wall to the left, in the 18 x 10 space, I would put a series of 12" to 18" deep pantries with cupboard doors that open. These are 6 ft of 12" deep ones I had in my previous house, and they were easy to use and nothing got lost in them.I put in that high workstation at 40" for when I needed to do any delicate work. It turned out that the dogs could not jump that high and it became the place to set pies and the like! The cupboard on the far end, facing us, is 2 ft deep and was the vacuum/broom/mop/recycling cabinet. Since you have so much room, one like that and another one with shelves for appliances would be nice to have. Putting them along the wall means that you can walk right past the bank of them and they will serve as walls of the hallway to the laundry room. You have so many windows along the right side of this room that I wonder where the laundry can be. Can you do a drawing of that end of the space, including the door to the garage and all windows? Be sure to specify the height of the bottom of the windows, too. In the kitchen area, what is the height of the bottom of the windows on the right side wall? Can you put a 38" high counter under them, with cabinets? Specify this for all the windows in the kitchen area, please. Are you completely open to the plumbing being wherever someone places it, or do you want to preserve some of the existing plumbing? If the later, please draw in where sinks, toilets, and any other plumbing already exists. My answer will bump this to the top, and others will be able to see it.
