Rapida, I actually like having two different handles on my faucet. I can adjust how much hot water and how much cold water as well as the force of the water. I personally feel I have more control that way than I do with the single handle one. Maybe its because my mother bought cheap faucets, but the one handle ones seem to wear out faster. I also like high faucets that can swivel.
Ok, just kidding on that picture.
I don't have a picture of my bathroom faucet because AquaSource no longer makes it, but the faucet has a high arch and swivels so it makes it easier to fill things and I can move it out of the way. It's very useful. I'll have to try to get a picture sometime.
Mediaman-- On the vanity you showed, I like the tower cabinets on top of the vanity because they make good use of the space.
I personally like the E series with the corner tub because I feel there is more use of space and that it will allow you to have more storage. Instead of a chair in the corner though, I would go with a small bench, maybe like this:
But I would have a single long cushion instead of two. I think in this one there are two lids that flip up to have storage under the cushions. I would want something upholstered and have a single lifting lid with piano hinge. But removable cushion allows for you to clean things or let you take the cushions off if they get too wet or something. You could store small items under the lifting lid thing, and then things could be put on slats underneath. Towel racks could be wall-mounted. That way they can't be accidentally knocked over.
Here's another storage bathroom bench idea
Has your wife said much about adding grab bars? It seems you plan to live in this house a long time and if her circulation has already gotten to the point that she cant feel the bottoms of her feet, it is only a matter of time before she will start to have balance issues. There are a number of solutions, but they aren't cheap. I saw a neat thing that is a 350lb grab bar for the corner, but it also holds soap and shampoo.
Unfortunately I think its about $175 or something.
This is a 500lb grab bar/ toilet paper dispenser combo
Aesthetically, I like the look of the E1 series (at least from the layout from above). For practical reasons I like E2 because it is convenient to have the toilet right next to the shower. Not to give TMI, but if I have to pee when I'm in the shower, I jump out and use the toilet-- my shower does not drain well at all so I end up being up to my ankles in water before the shower is over and I don't want to stand in pee water. There have also been times when we were out of toilet paper and I had to jump right into the shower.
I do think you should take a suggestion from Rapida and do a mockup with boxes or other furniture pieces and measure things out and see how things look and feel. So, what you should do is take a stool or chair and pretend it is the toilet. Then measure and set up two chairs on either side (with the backs toward you) to represent the vanity and the shower and have them set at the distance they would be from the actual toilet and sit there to see how it feels. Do you have room to move your arms? Are you going to risk smacking your hand into anything? Do you feel cramped? You may try this with chairs or furniture pieces while on your existing toilet to see how the space feels.
What are the gray box thingies behind the corner tub? Do they serve any storage purposes? I f they are to cover plumbing and serve as shelves then they are useful. It would be cool to have something on them be able to lift up so you could access the interior. Like if you have a water shutoff valve inside or want to store cleaning supplies.
Did you mention the lightbox faux window idea to your wife, or was that something you were not interested in?
If she should start to give you any grief, at least you didn't suggest this 1950s American Standard nightmare:
Btw, do you have any carpentry skills? If so, you may be able to make some modifications yourself. Some simple drawers can be done. I'm going to have to try to make some. I need to build my brother a dresser because the plastic thing he has is awful. Other than some shelves and a couple of boxes in woodworking class, I never made anything really on my own. But I helped my father build a custom desk with mirrors behind the shelves and a custom keyboard tray that is awesome.
There is a site called Ana-white .com that has building plans and pictures and such and explains what materials to use and exactly how to get the best use of materials out of builds. It will tell you the level of complexity of the build as well. If you're not comfortable building stuff yourself that's fine.
Edit: I forgot to ask if you know what sort of toilet you want. ADA height? elongated or round bowl? two-piece or one-piece?
I've heard the Drake II is very good and affordable, but I don't know what your wife would think of the look. The Toto Promenade has a shape at the bottom that is pretty and reminds me of one of the freestanding tubs you posted a picture of earlier. I don't know how that one performs though.
