I believe the architect of this home, Al Beadle, built mostly custom homes. I believe the EIchler homes were more tract homes. From what I have seen, most of Beadle's homes are large for the era. This home was built for the owner of the Safari hotel, and his family, which was recently demolished. You can see similar features in the hotel to my house.

I would look for a teak plant stand, to match your teak stool (which is a great solution for your problem, one that I share!). In addition to tying the stool and the stand together, the teak stand will not be damaged if it gets wet sometimes. I agree that the plaques of the animals would do nicely on your shelf. A glob or two of Museum Gel on the bottom of each one will help hold it in place so that they do not move. I have it holding my things on a narrow shelf in the Foyer, and I cannot now move them to dust! I have to dust around them. Granted, I could pry them off the gel and then reapply it, but they are so well stuck now, I don't want to do that.

I like the idea of centering the sink between the two doors. But another option would be to put drawers on each side and a sink cabinet with a two doors in the middle. I personally have a similar set up (drawers on both sides,sink in the middle) in several of my baths and find that I don't need as much counterspace. I can just open the top makeup drawer and leave it open while I apply my makeup, eliminating setting things on the counter and having to put them back later. Then I have creams/brush/lotions on the opposite side. You can even just do two deeper drawers on each side so lotions etc.. can stand up straight in the drawer. Just a thought.

1) Go with the 1" beveled. It's an upgraded look. 2) With either the flat or the beveled, place a couple inches (at least) above the backsplash versus touching. 3) The thicker, the nicer, but then you'll have the edges to deal with (framing). 4) Go with the sconces you like. If they turn out to be not quite "right", you can always replace them later. Just as an aside, do you regularly sit at your current make-up vanity? Or do you find yourself standing at the sink when applying make-up/doing your hair? If you don't actually sit there, that would be a nice place for floor to ceiling storage cabinet. BTW, I recently purchased a new mirror for my powder room and saw many large (30"x50") mirrors readily available on-line so you may not need to have them custom made.
