The vanity has to be something unique and solid as well. This sheer makes an amazingly different shower curtain too. This is the work of Genevieve Gorder, one of my all-time favorite designers, and one of the first to inspire me to become so interested in interior design.
Color is a huge factor in a bathroom- it should be something to wake up with in the morning, but wind down to in the evening. This green can be bright eye-opening enough, but in the right dimmed lighting can be plenty relaxing. The tile is amazing too.
