Is $4,850 to remodel a small master bathroom (labor only) a fair price?

Never hired out work before, just making sure this quote sounds okay. It's a small master bathroom that's in desperate need for a remodel. We want a tile floor and marble tiled wall backsplash, new vanity, new toilet, new surround, and new mirror/lighting. We also want a vent fan installed since there isn't one currently. My wife and I said we would remove the wallpaper and we would also paint. The bathroom isn't very large as you can see.
