Reforma de despensa/banheiro

I had water damage that affected a kitchen pantry which backs up to a bathroom. The bathroom was also affected and was old and unsightly to begin with. They will likely have to be demo'd. I would like to stay around $20-25,000. inclusing costs for fixtures, paint, supplies, etc.

When the pantry unit was removed it exposed the fact that there are 10 inches of unused space behind the pantry. At the same time, the bathroom is unnecessarily large. There is also a small closet in front of the bathroom that is poorly utilized. I would like to redesign the existing space to maximize the appearance as well as storage potential of the existing square footage. My challenge is that the space is small and difficult to manipulate. There is plumbing and walls that may have to be moved, but the budget is limited. In addition, the bathroom is part of the family room, but I want to avoid having the door to the bathroom directly open into the family room ( privacy issue), Finally, the area is next to the garage entry into the family room, so there are traffic issues to consider.

I am open to ideas. I like clean contemporary designs but not extreme modern. I would like either pull out pantry or walk in if space/cost permits. The bathroom is too large currently and I would be happy with a simple, warm but minimal powder room. Would love to turn the closet into some more functional cabinetry for when we come in and out from the garage, as we do not have a mudroom.
