I chose B because I love, love, love black and white rooms. Unfortunately I don't have any bathrooms in my house that are this big. The small hall bathroom is black and white and has the same basket weave floor tile and white wall subway tile from 1938 when the house was built.
I repainted the walls so they are white again. Since my husband is the one who most often uses this bathroom, I hung a large poster of a black 57 T Bugatti concept car above the mirrored medicine cabinet over the sink and a couple of smaller black and white graphic pictures on the wall space over the toilet. And there's an aluminum antique race car model on the top of the toilet tank.
I am in the process of designing and renovating the master bath in order to add a walk-in shower. Fingers crossed.
