It should fit, although it can be located wherever a drain is and the hose can be run to the spigot. If you have a basement, many choose that location, even if unit is 25'+ away.

Thanks for all the feedback everyone. Below is a sketch, the island has been pushed toward the fridge by about 4", but other than that, that's the plan. We are happy with the plan, and too late to really deviate for the sake of a stool (drywalling Wednesday). As you can see, the 2+2 doesn't really work, due to the fridge on one side and the dw along with what I expect to be a relatively high flow path to the door to the right that goes to a covered patio (table, outdoor fireplace, bbqs). I think you guys are right about it being better functionally, but it's not in the cards here. Should I stuff 4 stools with a corbel or just settle with 3? We will have a kitchen table in the top left with a banquette on one side, and seating for 6. But...my family currently gravitates towards the 2 spot counter seating we have in our current house, and would rather eat at the counter than being relegated to the kitchen table which is 3 feet away (me, wife, kids are 5 and 9). I can see what's coming here. 3 is the better solution, and I'll eat over the island on the other side ;>

I have a very long vanity right now. Two sinks, plenty of space in between them. One soap dispenser. As long as this vanity is-it's still..not like you have to cross a soccer field. I'm also totally fine with using my husband's side. BTW I also often brush my teeth there, and hand wash my lingerie there too. Unless I have enough lingerie for two sinks. I use mine also of course-washing face, etc. Mine is also closer to the medicine cabinet, my drawers, cosmetics, etc. One hand towel on the wall, my side. The other edge of the vanity doesn't have a wall next to it. We also have a shower where we have a soap, and a bathtub where we also have a soap, and I feel like we have enough soap in a rare case both of us need the same dispenser at that very moment. We can also take turns! You squeeze, then I squeeze! No messy trails-I usually wipe the counter right after I use it. (More than that, I also wipe counters in the public restrooms sometimes..I have a thing with wiping the counters I guess lol. My friends think I'm slightly abnormal.) I also take shower/bath twice a day ..just to clean my name in advance, in case you think I don't have great hygiene habits or something..:) I do have a nice tray with all my beautiful eau de perfume bottles..right in the middle of the counter. I think it enhances my bathroom experience. My husband doesn't have similar centerpiece. (poor thing) I truly hope though mine enhances his bathroom experience too lol.

Wow! For the record, I wasn’t posting a ‘rate my floor plan’. I am not so hard headed that I can’t receive advice, consider alternatives, or answer questions. From reading the responses, it seems our bathroom is so terrible that no one can even give input on how to address the questions I listed in my first post. I find it hard to believe it is so bad as that! Meanwhile only one person has said they have a counter such as I am asking about. I also never said I was unwilling to change things around, just that I didn’t think a simple swap of vanities would work. I even included a bigger view of the adjoining areas to show it would not be as simple as that. What even would you have me tell my architect? That some random people on the internet think her design could be better? I could spend my time trying to justify why we didn’t put the long vanity on the opposite side of the room, or under a window, or why I will be including a toilet room. And then you would either understand why we have come to this design, or you would tear my entire home apart. If you have ever built a home, especially a design from scratch custom home, you know that it is like putting puzzle pieces together. We all have our lists of must haves, wish items, and constraints of design and budget, and time. At some point you just have to decide to be finished. I actually never said I was in the design phase. Walls are not up yet, but none of you ever asked where we were in the build process. I’m an introvert and sensitive person who has had a pretty traumatic last year and a half. It’s taken me a while to feel like I can venture out of my shell and reach out to others-even in a basically anonymous way online. If I had read such negative and generally unhelpful comments a year ago, I would have probably spiraled into a deep depression and doubted myself, what I wanted in my home, as well as the talented professionals I have partnered with to design our home. It’s unfortunate that people can take the time to comment online without taking the time to read the post, think about whether they are giving any constructive advice, or if their tone is derogatory. Not to mention, ignoring the topic at hand. I have been a member since it was just gardenweb some 10+ years ago. From discussions about kitchens, baths, home building, and pools, I used to always find these forums helpful, informative, and a generally positive experience. I will try to remain optimistic that I will still experience that. Juls
