The bathroom is part of a Jack and Jill set up (two bedrooms connect to a bathroom in the middle) and I liked having the vanity area separate. Since the boys already share a shower I went ahead and gave them each their own sink and ample storage space.
Disclaimer: I did not design the layout of this bathroom. A bathroom designer did. I showed her the materials I liked and approved the final design—- basically I was just the customer on this one.
