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.
An easy DIY to add storage to a small bathroom. Just putting up some high shelves to store towels and baskets to hold smaller items. This is a great way to keep a small bathroom organized, while maximizing space.
