Cabinets. This is great! Hidden storage is always appealing. Any style could be worked for this and can be done at the tub as here in this picture, or in a small space in a bathroom. I can see it working similarly in a kitchen also.
Actually, I don't want a double vanity sink... I just want one sink with a big mirror. I like it when I'm brushing my teeth with him or i'm doing my make-up while he's fixing his hair next to me or behind me (since he's so tall ♥) cause I get to look at us in the mirror and we have those moments when our eyes meet accidentally. Hahaha. It's just that one sink = unexpectedly good moments :)
