I answered that we have two sinks in our bathroom and used both. However, my husband and I also have separate vanities. It sounds like some people are talking about having two sinks in the same vanity. I can definitely see how we would only use one sink if that was the case! In my situation, we each have our own vanities, which each have plenty of counter space, drawers for storage, etc. I love not having to share and having plenty of space for my own things.
