We need more pictures of the room. Will the fixtures be in the same spot? What color will they be. Are you planning on tiling behind the vanity as in your present powder room or are you switching to a vanity with a framed mirror as in your other photos? I would paper only one wall - the one behind the washbasin, if you are going with the pedestal. Then paint the other walls a lighter shade of the same color. Both of the papers you showed are lovely, but sorry I disagree with your decision to avoid blue because you have blue in the kitchen. I think it is more harmonious to carry colors over from one room to the next. So if you really want yellow or green, you might look for a paper that has a bit of navy with either of those colors and then use navy for your towels and other bath accessories. I do agree with ILoveMod that the floor is too earthy and rustic for the paper. If the flooring is also in adjacent rooms, I would stick with that flooring and look for a more muted, olive green. Below is the kind I would look for. And then I would get hand towels in that muted green and navy. You really need to get a little sample of the paper and hold it against the flooring tile and see it in the lighting in the powder room. Of the two papers above I prefer the top. If I used that I'd consider painting one small wall or a soffit or even the ceiling navy. I like the middle one a lot too. With that you could paint the walls yellow, but not too bright. Good luck with it and please post again to let us see the finished room.

I'm also loving the moody blues but I agree with @jck910 in that the paint should blend with the floor. I was going to suggest SW white egret but I just watched a video on it and the video said if your room doesn't get a lot of light it will make the room feel dingy. I used it in a room with two sky lights so it wasn't. That said, I think something warm and white/creamy would be good just from looking at our picture. I would freshen up the trim and window sill with SW extra white in semi gloss. So many colors to choose from!

Thanks for going back and forth on this with me. I definitely want a pendant. (Just one since I don’t think there’s enough room for two.) I think the pendant will help being the ceiling down. if I install a pendant, then would o get rid of the light above the sink? Probably right? In which case maybe I would install a cluster. I also have considered a lighted mirror. Here are a few inspiration photos. I agree that tile might work behind mirror … it needs texture of some sort. I think some of your ideas about wood on the ceiling are too much for me to tackle. Trying to streamline.

Why not just have the same blue paint you have now on the top half of the walls? Your picture doesn't show the sink so I don't know how big it is. Maybe it would be cheaper to just replace the sink with a small vanity with a marble top and backsplash? You're going to have to remove the sink and toilet to tile that wall.
