Our bathroom is pretty straightforward - bath, shower, sinks, toilet. We painted the bathroom after we moved in but I hadn't found anything that I liked to hang on the walls that wouldn't be impacted by the steam.
Today, I think I finally found the right thing! Hobby Lobby's wall decor was 50% off and I saw two "ceiling tiles" that I thought would work.
I'm not sure the brown is the right color but it does tie in to the comforter we have on our bed. I figured the worst thing that could happen is I end up repainting them to the right color but for the time being, I'm glad there's something on the wall. I want to get a basket to put on the back of the toilet for extra rolls of toilet paper or something - we'll see.
