When you're both getting ready, are you both using the sink? For me, I would prefer the single sink with storage over a narrow double pedestal with less storage. While I do have a double sink and I like having it, I would like it a whole lot less if I did not have enough counter space or storage. We rarely are both using the sinks at the same time. I just enjoy being able to have a more pristine sink that's "mine" even though we are usually not both using sinks at the same time.

We have that also...30" cabs on each end. I don't know what kind of mirrors you're doing over each sink. But if they're coming in from the wall a little...say two inches on each side, that's bringing your mirror width to 26". You may also want the lights to come in a little also. Personally, I'm doing double sconces over our sinks. I like the look this gives better and there's plenty of light with the other lighting in our bathroom. Some images for you to peruse:

It shouldn't be a big deal, but you would have to first remove the old vanity and then open up the wall and do some re-plumbing. You would cap off one drain and one set of hot and cold pipes in the wall. Then you would need to route the other drain and set of hot and cold pipes laterally within the stud space so they would be in the center; this might require notching out one stud, depending on where things are located. Which set of pipes you would choose to cap off might depend on where things were in the wall in relation to the studs: it's possible that one side might be easier to re-route to the center than the other, or one side might be a shorter run to the drain. It's hard to say before you open the wall, but that's the general idea. Once you re-did the plumbing and repaired the sheet rock, you would be ready to install the new vanity. Oh, and if you don't have shutoff valves under the sinks, use this as an opportunity to install a set on the pair of supply lines you will be using. Hope that helps. Feel free to re-post if any of this is vague, or once the wall is open.
