I remember in my first house, I made a recessed closed niche all along the vanity between the faucet and the mirror. I found it really useful, I just wish I could find a better option than sliding doors to access the inside. I don't know, if 30 years later there would be a better option ... maybe you can make that recessed space higher than the faucet and have a pressure button latch that is hidden at the back of the door (sorry, I am missing some english vocabulary, hopefully you understand what I mean).

We are adding a bath and went for a larger version of this floating vanity - ours isn't installed yet, but I really like the idea of making it easier to clean the floors (and that's a good idea if you're hoping to age in place!). You do need extra support, so it's worth being sure of that before choosing a floating vanity. I like the look of a floating vanity - the Ikea Godmorgon would be fine with me except that neither is this a DIY job nor is there an Ikea store anywhere near here. A truly floating vanity may not be feasible anyway, because the plumbing runs down through the floor. On the other hand,the pipes are close to the wall, and because the room is so small, a box enclosing them would not be visible (nor would the pipes themselves, I realize). it will bum you out if you redo your bathroom and sell your house only to find they've ripped out your new bathroom to do what they want with it I would probably never know! The seller of this house and I never met, and if I were to sell the house within just a few years it would be to move out of the area. In practical terms houses in the immediate neighborhood go to first-time buyers who are financially stretched and can't afford to make any large changes for a while. While I love the idea of putting in a retro bathroom I might feel differently if there were anything original to work with beyond the door and window frames, and if the flowering of mid-century design had reached bathrooms by 1951. I have some pictures of original mid-century bathrooms that I like, but they are all from houses built about a decade later. Some of the design elements in them have now come to be considered fresh and new. Thanks for your comments.

You can do very skinny vertical sconces with low power lighting through the wall to wall mirror. But that’s a lot of expense to go through for a look that really isn’t the ideal.

You can get away with doing it any number of ways. I'd probably keep the plumbing fixtures - sink and bath - the same. If it were me, I'd go with brushed nickel for for plumbing fixtures and either a white or thin black frame for mirror - but that doesn't mean you should.
