The reason I think dual sinks are so important to family bathroom is that you increase your bathroom’s functionality by a large margin. Now, another element that is a must with this sort of setup is the large mirror you see here. Now, if it is just you and a partner that share the bathroom, then you might consider two separate mirrors, as that can look quite nice. But in the case of this bathroom I think the single large mirror is the better option. The toilet next to the sinks is a traditional design, and the bathroom looks like it has a single showier and tub unit in the space.
