This Bathroom Floor Plan is a great choice when the bathroom will mostly serve as a powder room, but it still has a shower for the occasional guest who requires it. Place the sink and toilet in a room off the hall, with a door leading into the shower room beyond. You might think it is strange, but it is a great option for someone who wants a room that looks like a powder room but can handle the occasional showering guest. This Bathroom Floor Plan allows you to serve the bathroom with a full guest bath and a powder room.
