What fun! Can you tell us a bit more?

What is your budget? Is there tile on the floor? What color is the commode?

Do you need a cabinet-type vanity for storage?

Yes please, more clues and photos if you don't mind. My first thought, if a powder room, for guest? rather than daily use, maybe LED lighting behind the mirror. Is the ceiling normal or high, a LED crown mould too? LOVE your Grandmother's mirror and it will create a spectacular powder room. Help us understand the space and where this door is located/seen and colors from the rest of your home. This is a fun one!!!!!

House is not built so options are open though the floor will likely be a continuation of the wood from the adjoining rooms. The room will be built up under a stair so it is small. We will use a pocket door to maximize space. Yes, I do want a tiny bit of storage...just enough to hide spare tp and hand soap. Don't care what the counter material is.

If it matters there will be a small wet bar across the hall about 4 feet. We haven't made all of the decisions about that either. The last thought was that we might use a copper sink with a lit artistic backsplash. The wetbar will definitely be stained a medium dark brown.

Don't know quite what to say about budget. I would love for it not cost a lot though I know it's relative. The powder room will definitely not be the wow point for my house. I'd rather it be closer to "builder" grade the billionaire. I'm more likely to spend $700 on a light than I am to spend $3000 on the vanity. Does that help?

That mirror is scrumptious!

I would love for it not cost a lot though I know it's relative.

A wise decision. Put the $3K in savings. How about poking around some antique stores looking for a piece that can be turned into a vanity? You can also haunt CL. Even goodwill might have something if you add some wood appliques, or otherwise get creative. Then put the money into a marble top. CL may help you there, too.

Have you looked in our gallery at the bathrooms thread? And at the cottage decor thread?

Ok, Here are some ideas to play with
Uplighting

Thats a great Colonial Revival Chinese Chippendale style mirror. Craftsman has a fair number of Asian influences so perhaps a fixture in the craftsman style would still work nicely. I think if the fixture matches the style of the house, that can work as well as matching the mirror, which is a single decorative element.

Check out the craftsman fixtures at Rejuvenation or Arroyo Craftsman.

The Port Orford or Ranier from Rejuvenation are lantern like.

Arroyo has some great lanterns including a line called "Pagoda" that is a highly asian influenced craftsman style.

What a wonderful mirror! Since I don't know your style, I'll just throw these vanity/consoles out there. I think the copper sink looks better than the white, too.

I think an asian inspired cabinet (maybe in red?) with a vessel sink and wall mounted faucet would work well with your lovely mirror.

Of the vanities posted above,I think the bottom right one works but the others seem a bit cottage style (which I love, but perhaps not with such a dramatic mirror).

I would think about a Chinese Chippendale style for the vanity, in a darker wood, something along these lines:

chinese chippendale bureau

or an Chinese altar style, like this (only deeper to accommodate the sink), again in a dark finish:
altar cabinet

Red walls, or an oriental themed toile paper or fabric on the walls would work. Or, in keeping with the craftsman aesthetic, perhaps a grasscloth on the walls instead.

Then a pair of these hung from the ceiling in front of the vanity area:

drop crystal pendant

mjib, Thanks for the photoshopped options. I kind of like the first one, something about it's simplicity. Can you tell me where you got that one?

les197, I LOVE the crystal pendants and believe it or not my husband likes them too. I,too, had been looking at the altar cabinets, but I really don't want to use a vessel sink in there.

Thanks everyone for the ideas!

I thought the first style would relate to your casual craftsman style house. It is an antique adaptation, so it would probably need to be made custom for you. The link has a number of views that might help with that. It is a simple shape, with just a small flourish at the bottom. I think what adds to it is the color, the drop type hardware, exposed hinges, and copper sink.

Good luck with your home - that mirror is just gorgeous!
