ummm, I haven't any. I put up bn look command hooks for the wet towels on the face of the shower as a temporary measure until I could decide on what to get. I only have one place (in that huge bathroom) where I could hang a bar, but the area ended up being a few inches narrower than I thought and am worried about it (a bar) encroaching on the space where the toilet is. I've got my eye on the tp holder that matches the faucets. It's brushed nickel and since it would be on a painted wall, i think it would look better than the orb. But can't commit until I decide about a towel bar for sure and the matching towel bar sets out too far from the wall for that space. So I am pretending that someday I'll figure it out - until then the tp sits on the back of the toilet. I am the only user, so it's fine.

IMO it really depends upon individual situations. Proximity weighs in, too. Of course, all the same finishes is fine; but that does not mean mixing isn't to be done, just that it needs to be done thoughtfully. A mix can draw attention to what you want to be focal points and can make a room be more interesting visually. In our guest bath, all of the finishes are brushed nickel, except the TP holder. But the TP holder is attached to the side of a dark wood vanity, and I did not want to draw attention to it. The antique bronze blended in perfectly, yet does not look out of place because it is visually an extension of the vanity. Along those lines, shower curtain rods, shower door handles and toilet levers are often not a design feature you want to accent, so I would use what would make them visually less noticeable. Ceiling lighting and sconces generally are the same finish, but I believe you can successful pull off an outstanding antique bronze chandelier, for example, by having utilitarian sconces and faucet fixtures in a nickel finish. Items on the same impact level, such as faucets and towel bars, I would usually try to keep the same finish. If the faucets are the focal, they could be one finish and the balance of the other items in the room be something else. As for proximity, I believe all the finishes inside the shower can match, but be different than the finishes in other areas of the room, IF there is a reason/point of doing so. A shower head in one finish and the shower knobs in another would be trickier to pull off but may work if the finish of the knobs blended with the tile so the shower head becomes a focal point. Some finishes mix better than others. And the design style of the features in the mix matter. As does the backdrop, as mentioned above.

I am not trying to be argumentative, but the problem is that the cheap silver drive in grommet is what a lot of people consider standard. You can walk into almost any new construction here that is on the market for $500K and the cheap silver drive in grommet is what you get. The owner of my practice lives in a house that is worth more than $2M and it has this on "secondary" doors like bathrooms and closets and $12 pocket door hardware. You have a higher level of expectation of what "standard" is. Frequenting Houzz and other sites has developed this. That's fine, and I am in complete agreement with you about what sorts of details are important. But what you desire is no longer "standard", its above the standard, at least in my experience, and I look at a lot of real estate and look at details such as this. Sometimes I wish sites like Houzz didn't exist, because it takes my already high expectations and makes them higher: we are seeing photos of work that people are particularly proud of, not photos of work that is standard or average-particularly if they show details such as this.

I agree with Yaya, you have wonderful taste! I especially like that shower door. And I agree that mixed metals can work. I wouldn't try chrome with brass, but what you have in mind should be fine. I left the matte black doorknobs and hooks on our bathroom doors and put satin nickel everywhere else. Except in the shower, where the three grab bars are polished nickel, as the company didn't make them in satin. It depends on where you install the various items. I do have some doubts about the sink in the picture. It looks like there would be a pretty significant splash factor. When I wash my face there is water outside the sink, and when using the Waterpik, there is water covering the inside of the sink itself, and we have deep oval Kohler sinks. It's a very spiffy, modern sink, but is it practical?
