The first one. The second one with the palm trees and the lighthouse .. has a tropical feel. If I was going for european country in the rest of the house I wouldn't want to introduce the tropical thing. That is just how my mind is reading it. I really like number one .. it is unusual too. I think you could do better on the red wallpaper though. Look for something similar without the boxes on it :)

I love black and white elements, but didn't care for your wallpaper choices at first glance. Seeing your inspiration pictures changed my mind about the stripes though. I'm still not keen on the spots (maybe if I loved dalmations), but I think the stripes look really cool :) I want to do something fun and dramatic in our powder bath, where we have bead board on the bottom and a pedestal sink (a lot like your inspiration picture) with polished nickel fixtures, but I can't seem to commit to anything. For years I've kicked around ideas of painting the upper walls a dark color and/or covering it with a gallery wall (like ttodd's black and white gallery wall in her family room), wallpapering the upper walls, or painting a wallpaper-like stencil on them. But I can't seem to decide, so it remains a boring yellow color. I do like the bead board, but it limits my choices because whatever I do has to work with it. With your blank slate, I think you should go for the stripes :)

I have the same size powder room. I could definitely see papering all the walls. There's that long blank wall across from the door where you'll need to hang picture/s and that will break up the pattern.

Well, you can do what you want as it's your bathroom, but I will mention that you don't have to "bring out" or match any of the fittings in a powder room. You can do anything from this: To this: So the question is what style do you like? Vintage, mcm, Victorian, contemporary....Look at other rooms that you love to discern your style. But if you're going to invest in wallpaper, you should make it smashing, imho.
