For Master Bedroom: Whatever your closet space, Peri Wolfman advises "potentializing all the storage possibilities" by making use of multiple levels (these racks are two bars deep), placing shelves over doors, and putting hooks on bare walls.
this towel storage tower is what I would like to the right of the shower (when you are facing it). On the back side I would like drawer cabinets, toilet side. We would take the space from the too wide shower to add this new wall of storage
Narrow walk in closet with lots of built in shelves.of course the reality is that if this was your closet, it wouldn't look like this. Not all your clothes may be black and I'm guessing those nice shelves would be full.
