INTERIOR AMMM by architecture, via Behance - Narrow vanity alongside the tub. This is what we have only our sink is centered (way too close to the toilet). I was having trouble finding images of off center sinks in this configuration.
I think this was designed for a pre-teen/teenager, but there's a lot I like for a guest bedroom/home office. Love the built in desk and storage and love the blue, white, bright green color palate. The ceiling fixture is especially cool.
