So after my last post on bathrooms, I decided I should come clean and show you my bathroom, which does indeed have a wood vanity (but not a wood toilet seat!).
I don't think the dark wood vanity overwhelms the room. I tried to use a lot of bright things throughout the rest of the space (a large mirror to reflect the window opposite), nickel faucets and such, white towels, and a creamy marble countertop.
I made the roman shade over the window out of a thick brown linen and trimmed it out with some cream grosgrain ribbon. I am a big fan of that window; it makes the smallish room seem a lot bigger, and I just like having natural light in a bathroom.
So there's my confession in photos: as much as I love all-white bathrooms, mine is anything but! :)
