Installing tile backsplash over bead board

I'm wanting to replace the vanity top in my bathroom. The way the bathroom is set up means that the vanity is positioned between two walls. There are lots of vanity designs I like but all of them are 49" wide. The problem is that the distance between both of the walls is only 48". So I have to lose 1" somewhere in order for a new vanity to fit. What do I do?

This may open up a whole can of worms, but I have to ask. We're looking at remodeling a guest bath and a bath in our bonus room (the guest bath is 9' x 5'. The bathroom in the bonus room is 7' x 5'). We're going to have the popcorn ceiling scraped and skimmed, repaint the ceiling and walls, replace the cabinet and vanity, have the linoleum taken up and new tile put down, and re-use the toilets (for both bathrooms). There's also some thin plywood on the subfloor in the bonus bath that we'll probably have taken up before cement board (or similar product) for the tiles. We've gotten a few quotes so far, and they range from $7000 to $14000. Since these are pretty small projects, does it make sense to hire a contractor, or would we be better off hiring individual companies ourselves and manage these two projects on our own? It just seems like a lot of money for the size and scope of work. We've never remodeled before, so maybe that's part of the issue to. We weren't sure what to expect. I removed the baseboard, linoleum, cabinet and vanity in the bonus bath, as well as scraped the popcorn off the ceiling. I can do a lot of the "demo" myself. Any thoughts or opinions are welcome.
