We are planning a remodel and we will have some extra room in the back of the house which could be an additional small bathroom. The bathroom would only be accessible from the backyard. We enjoy entertaining and having people in our backyard for BBQs and think it could be nice to have people use that bathroom rather then walking into the house, through the living room, and to the bedroom hallway to use the restroom. Would it be odd to have an bathroom that was only accessible to the backyard?
