I don't think it will be a deal breaker to have one sink with good counter space. Personally when in the bathroom want it all to myself. I don't want to see my husband spitting toothpaste next to me and vise a versa.

As posted, there are several extensive threads on the subject so just do a search for more responses.

I just remodeled and went from two sinks to one sink because I wanted more counter space with a dedicated vanity area. For all the reasons cited, two sinks was completely redundant to my lifestyle - I need water to wash my face and when brushing my teeth.

In your circumstances, I certainly wouldn't go through the expense of that kid of remodel to add a second sink since you don't need it for your lifestyle - especially since you are not flipping the house.

You say you have a dressing area? How practical is that space? DO you actually use it? I think it would be a more effective use of space to take down the wall and enlarge the entire bathroom. Maybe if you did that your husband wouldnt go down to the basement anymore? I don't know if you plan on selling in the future or staying there forever and only you can say what would work for you but if its what the majority would want I would say axe the dressing area and enlarge the entire master bath into one space with two sinks.

I would not even consider a double sink vanity unless it can be 72 in. long. I prefer by far more counter top than 2 sinks. Think also about the floor space you have for 2 people to be in the same room at the same time. Could you two be able to move freely?

Count me in the one sink camp. It is rare that we both want to use the sink at the exact same time. Our master bathroom is so small that you couldn't accommodate a second sink without major renovations and sacrificing closet space. Not on my watch.

Also, my neighborhood is a 50+ yr old tract neighborhood. While many changes have been made to kitchens over the years, very few of the master baths have been updated to include two sinks (no one wants to sacrifice closet space) so there is no fear of comparing poorly to other homes when it comes time to sell.

I wouldn't *not* buy a house b/c there was only one sink in a any bathroom. If someone wants to have two sinks, they can take care of that when they buy a house. I wouldn't go to any great lengths/dollars to remodel something in order to possibly make my house easier to sell in a possible future to possible buyers b/c who knows what a potential buyer might be looking for. You'll never please every potential buyer, and especially if you let's say stay there for 30 years, why worry about someone that far into the future?
