I wanted to open up the space as much as possible, so I chose a light grey paint for the walls and yellow as the accent color. I tried to keep the decor minimal. I changed the light fixture with a more modern one from Home Depot. I also bought a glass shelf from Pottery Barn to keep the "open" feel.
I was so pleased with the openness of the glass shelf, I continued the idea to the tissues. I found this interesting tissue ring by Vessel Toro at the Museum of Modern Art in New York, but wasn't crazy about putting the tissues directly on the toilet lid. So I bought a glass guest towel holder from Pottery Barn and put the tissues inside.
Overall, I'm happy with the way it turned out!
