Just adding more pics. Thanks for looking!

In powder rooms it's much better when the wainscoting is the height of the backsplash.

Thanks for looking. My vanity is 35" high and the wainscoting is 40" high.

I need to see your space not just a vanity which BTW IMO is kind of useless for any storage anyway. Is that the light you have or one you are thinking about? Post apic of your PR as it is right now. Post here in a comment DO NOT start another post

I like the wallpaper sample with the light background. While you can certainly do something more dramatic, I think this would be beauiful. I don't know whether you were thinking of wallpapering all the walls, but I think you should do that instead of just one wall.

Agree ^ I also like the lighter colorways - feel ”fresher” to me

A strong paint color or wallpaper (do not suggest grasscloth) or painting white is such a personal decision. For anyone to advise will be solely based on their tastes, especially without seeing the vanity in place and flooring. I’d start with painting the vanity a pretty, warmer shade and the walls a warm white, and remember lighting, mirror and art will have impact.

If you decide to paper, you didn't really waste your time painting if it helped you to make up your mind. I’ve wallpapered a small powder room and it‘s no fun, especially if the repeat is large but it does make more of a statement and suggest rich saturated shades.

@Maureen, thanks. Everything you posted is lovely!  Since the vanity is already a color (Dove Gray according to Home Depot), I would probably leave it. But it would be prettier against a warm white as opposed to the Agreeable Gray that the walls are now. Or a light colored wallpaper.

@Patricia Colwell Consulting, thanks. The light is one I'm considering. I want gold this go around and have already swapped the knobs on the vanity for champagne gold. For a powder room, the 6 drawers provide enough storage for my needs.

@Maureen, I really love that York wallpaper. Going to my local store today to look at it. And I do think that I will paint the vanity the color Smoke you posted--it will make it look more custom. SW White Duck is the warm white I'm thinking of for the wainscoting. What is your favorite white for trim?

@Beverly, thank you. Pretty paper.

I would paint the wainscot and all the trim the same color as the vanity and use the wallpaper with the black background. It's such a small room and you'd make a dramatic statement with that wallpaper.

@Diana, this paper?

Yes, that is gorgeous! Who makes it? Can you post a photo from closer up?

If you use it, pick a grayish blue for the trim, something that would work with the paper and the vanity color.

@Diana Bier Interiors, LLC, that is from Rifle Paper Co. Peacock

I am drawn to all of these!

@Diana, here's a close up of the Rifle paper. Do you not think it would look good with white wainscoting?  Txs!

This might not fit your design but this is one of my favorite wallpapers.

Becky, I think white wainscoting would look okay, but a gray/blue from the paper would look better in my opinion.

If you go to Hygge West web site, you can upload photos and see how it looks with the wallpaper.

@ROCKYBIRD that is such a sweet paper

SO different but love them both. Affordable at $70/dble roll.  The wainscoting will be the color of the vanity, Behr Dove Gray. Gold fixtures. Cannot decide which way to go.

^ agree — it’s funny I had said light above but now seeing the choices the dark colorway is terrific and I think the light might seem a bit washed out

The darker paper above is striking!

You posted 1 pic that shows the floor in room - is it black rectangular tile with large white grout lines? I’d sure be factoring the floor in with the wallpaper choice even though not much of floor will show once pieces in place. The post you showed paper you were drawn to has multiple dark black? floral patterns - they’d be great with the floor. I’d want to match floor color & make sure the vanity & trim colors are included in the paper design.

Thanks, everyone! I'm going with the dark one. The floor is 24x6 dark brown tiles (prior owner) with light taupe grout. Stay tuned for an after pic! Going to take about 3 weeks for paper.

@Diana, I was only going to paint the wainscoting the vanity color and leave the rest of the trim white. I think that will work since the vanity top is white marble and the paper has some white in it. Thoughts? Txs

So glad you're going with the dark one!

However, I think you should paint all the trim and wainscoting the same color as the vanity. It's a small room, and doing two different colors on the trim is going to look choppy.

@Diana, I can see your point. So the ceiling and door will be the only white?

Actually, the ceiling could also be the color of the trim, but white is okay as well.

The inside of the door should match the trim in the powder room, and the outside should be the same color as the hallway trim.

I have the rifle paper wallpaper in my bedroom and I love it but I think for your bathroom the lighter color looks better with the vanity. The rifle paper has more cooler tones.

She already decided on the dark one.

What bluish gray color paint would go best with this Rifle wallpaper? I thought the vanity from Home Depot was Behr Dove Gray but it's not. Saw a chip in the store today and that's not it at all. My DR is SW Online. Seems to match the vanity pretty well. SW Upward or Windy Blue might work too or Help! Thanks

The colors are not accurate in the last photo. The paint strip does not read that blue in person.

Becky - if you can remove a door or drawer from the vanity the paint store can mix an exact match.

It's difficult to give you advice on color online. If the paint strip is not that blue IRL, then we're flying blind. I agree with KW PNW Z8--take the door to the paint store. If you can't then take a piece of the wallpaper and try to get them to match the blue-gray color.

Just to say--the wallpaper looks totally different in the photo in your house than it does on the wall in the store. Thus the problem of color selection when viewing online.

UPDATE. So I decided to paint the wainscoting BM White Dove. I have not bought wallpaper yet. Still love the Rifle dark paper but just can't seem to pull the trigger. It's giving me 90s Waverly vibes. (I had a black floral paper in a bathroom with the ex husband and not a good memory!) At this point, I may just paint the walls since I'm so indecisive on paper. My townhouse is very neutral and I want the wallpaper to look like it belongs. I could go with Agreeable Gray again but want something different. Should I have them color match the vanity? Paint the walls White Dove, also? Something else? Still hang wallpaper?Thanks!

Wall paper is a definite commitment but if you’re not feeling it yet then paint is the answer for now - IMO. I think the vanity needs some color support. How about some baby steps. I don’t know how much of the back wall the mirror will cover - have you shown us the mirror? Get paint color matched to vanity & then paing the back wall same as vanity - stand back & assess. Maybe add the 2 side walls - stand back & assess. The result is a pale colored filled space which should look nice. Leave the other walls same as wainscoting - white dove. Hang art on the wall facing the door & make sure the art has the color of the vanity in it. Question about wall behind toilet - is that wall paper or what? If you’re not adding the dark wallpaper now it seems like that sparkle wall can stay. The art should be framed in the same color - looks silver.

Yes, it's wallpaper. It was an accent wall but it never worked. Mirror is a beveled oval but I'm going to need to get a new, smaller one in gold.
