There's nothing better than an impulse purchase that could actually work in multiple places/ ways in your house. (The secret: pick something in a color that is a major player in your whole-house color scheme, and in a pattern--like a stripe--that mixes well with almost anything.)
Right now, I'm leaning towards using my striped Schumacher wallpaper in the powder bath, sort of like this:
I recently remembered a bamboo plant stand that I had stashed away in the basement; it makes a great little occasional table for a powder room. I bought those vintage Chinese drawings when my husband was planning to rent his own space for his practice, but love them stacked on the narrow wall over the toilet. Loving the black and white inlay mirror and how it relates to the other Indian pieces in the house (mirrors, coffee table). We have contemporary white square sinks, and while I love the softening effect of the girls' gathered sink skirts, in here I would go tailored like the trimmed orange table skirt above.
But it would also look great in the upstairs hallway....Or the laundry room.....
