Try adding black/chrome light, black rectangular mirror (as the rest of your bathroom is very linear), and black/chrome pulls. I see that your door hardware is black (tying to that feature). Then add pops of color in your towels, window treatments, accessories, art, etc. A few idea starters below:

I'd stick with chrome. Keep it simple.

Is the wall finished? Are you going to install sconces? It seems like you need a lot more lighting. I would add recessed lights above toilet and vanity for more general light...sconces flanking your mirrors for task lights...all on dimmers and separate circuits.

You can always easily jazz it up with art work and colored towels.

I really like the oval mirror you are thinking about. I also would not get over head lighting, but sconces at eye level.

My friend recently did her bath and got these in polished nickel. They are gorgeous.

I also like these. They are a bit fancier.

These are classic and sleek.

Well everyone I don’t have but two wires. I really don’t want them to have to get back in the attic. There is a light over the shower and a main center light for the bath and a recessed in front of the closet area. We tried to add more recessed lighting, but due to the rafters they could not be spaced appropriately. My door hardware is a Venetian bronze. Doesn’t have the Cooper undertones....which is how I wanted it. So I guess that would be the color to tie in instead of black? keep coming back to the window and the shape of it and a rectangular mirror next to it. Too many straight lines. It’s my last decision and I just can’t seem to pull the trigger? Am I not wanting this to end...lol.

It's very pretty, but not at it's full potential.

If ever there was a wall meant for great tile, it's yours. So many options you could do to make this room a showpiece. for some warmth, try a wood stool, a pop of color, green plants, orchids, maybe a wood shelf or two over toilet, woven wood blinds, etc. do you have any artwork for that one wall near the toilet?

close up of accessories that make this otherwise white/sterile space, inviting.

some examples of how details make all the difference in meh and 'wow'!

all white bathroom is warmed by the walnut. do some walnut shelves, maybe a stool or little bench.

full mirror with sconces cut to fit over it.

another mirror/sconce example. love the wainscot around the room too

I would have done a cool design in tile on that wall

Old meets new. these antique wood mirrors are kind of cool

I think you need a medicine cabinet over each sink. They should be mirrored and wall-mounted to avoid any studs-in-the-wrong-place issues. There is only one shallow top drawer between the vanity cabinets, and I always give each person using the bathroom regularly his/her own drawer. When you don’t each have a drawer, the medicine cabinet may be where your every day implements are kept...on the bottom shelf in a narrow plastic removable tray or bin.
For the best lighting, I like both wall sconces and a row of recessed overhead lighting (set every 18” about 24” out from the mirror wall): it gives you good direct and indirect lighting for grooming.
I use the same metal finishes for all fixtures.

Beth H I love the woven blinds and I do have a couple pieces of art work that I can use on that wall. They are fairly neutral, but with a dark frame. I don’t have a picture of them to show you. I like the stool idea as well. My biggest hurdle is I don’t know what to do with the mirrors, lights, and cabinet hardware. I know I can stick with the chrome, but was wondering if I should go with a different color to bring in some warmth. I’m sure I’m over thinking this, as I always do.

well, I posted many diff mirror styles. I like the first 4 examples for your set up.

if you want more modern, do a hotel style LED backlit mirror (they aren't cheap )

more glam, try the beaded type of mirrors. they have a mix of soft gold and silver.

I still think you should do something w/that wall (s).

You must add more lighting especially at the vanity area. Side sconces not overheads. I have never seen a vanity without lighting. I have those type mirrors you posted and like them very much. I think once you add cabinet hardware, some window dressing, a plant and color through towels and accessories it will look more complete.

You girls are making this difficult for me. I know the sconces will look the best and give me better light, however, I only told the electrician to run two wires. We had to add the window to get the natural light in there and I wasn’t sure about placement for the sconces in relation to the window and wall.
I don’t want them back in my attic, since they made a tiny defect in my ceiling when adding the exhaust fan. I’m gonna probably regret this, but I am going to stick to the overhead lighting. It’s already been a long drawn out process due to hurricane Michael and redoing a lot of stuff. This is the last thing to get it completed.

Beth H. Would wall paper be an option for the wall/s?

sandra, yes, it would. I actually thought about that option too but wasn't sure if you were up for it. You could choose to do just that one wall. I also like the wainscot idea.

you could do something like this. it's simple/easy. but to make it look just a bit better, get a larger backsplash piece like they've done here

or remove what you do have and tile about 6" up the back with a nice looking mosaic tile

as for the lighting, when you say he only ran two wires, what do you mean?

were you going to do sconces? yes, that should have been done before the finish coat on that wall. you could opt to do some pendants.

In mine I did a ceiling light and sconces, and I have a window. I rarely use the sconce lighting though, but it does add to the overall look.

BH. So many great elements to your bath! There are two wires behind the wall for lighting that he will pull through when I get the fixtures and decide where to mount. He didn’t want to try and set them with the junction boxes and then them be in the wrong place. I love wall paper and now with all the removable products I would be more than willing to add some. I have this vision of how I want it to look, but finding the products without spending hours of time researching and then getting them to the house is a lot. I’m not where I can just go find them and bring them to the house. I am a day away from any major market and then it is not a sure bet. I’m also trying to be practical with it all. Everything else has fallen right into place and my Husband wants it finished like last week...lol. Thanks everyone for the ideas. I’ll send a pic when I’m done.

Ok to clear something up.
There are wires for vanity lighting behind the wall. There are only two...one for over each sink. And there is an wire for an overhead light in the ceiling.

What light did you go wtih? I'm in the same predicament and trying to decide. I have a small master, so I'm leaning towards one large mirror instead of two....although, I think the two mirrors give a more updated space...

Hi Classic Comfort. I walked in TJ Max while
traveling in FL and found two of these and grabbed them. Really lucky to find two matching so figured it must have been an omen. I think they look perfect and only $79 a piece.

And I do have cabinet hardware now.

And a shutter for the window.

Looks beautiful! Gotta love TJMaxx/Homegoods! Do you have lighting overhead in addition to the fixtures above the mirror?

love the runner in front of the vanity. gives the space just enough color and pattern.

I'd get a small little table or a small wood stool, put it under the window and have a plant or orchid on it. that little corner would look great that way

or better yet, hang one.

but I'd still do a little teak stool or a little marble and wood shelf w/orchid or plant

Oh classic comforts you would ask. I do have a electrical box for an overhead light, but I don’t have one installed. Had plans to move the one in the bedroom to the bath and get a more decorative light for my bedroom. That has fallen by the wayside along with so many other things I need to accomplish. I am really bad about waiting for the perfect item and then it’s been a year and it’s still not done.

Beth H love your idea about a stool and have given that some thought. Just haven’t found one. I love decorating and shopping, but I’m several hours away from good retail shopping and some things I just want to see before I buy. Not to mention it’s been hard to get out and about these days.

you can find most of these on Wayfair or Amazon. and both of those have easy returns.

Thanks Sandra. I'm pressed, because I have a contractor working on my bathroom. But, it's worth the wait, if you can for the perfect item that you'll cherish and enjoy. All the best to you!
