The space behind a door is a storage spot that's often overlooked. Build a set of shallow shelves and mount it to the wall behind your laundry room door. The materials are inexpensive. Measure the distance between the door hinge and the wall and subtract an inch. This is the maximum depth of the shelves. We used 1x4s for the sides, top and shelves. Screw the sides to the top. Then screw three 1x2 hanging strips to the sides: one top and bottom and one centered. Nail metal shelf standards to the sides. Complete the shelves by nailing a 1x2 trim piece to the sides and top. The 1x2 dresses up the shelf unit and keeps the shelves from falling off the shelf clips.
Locate the studs. Drill clearance holes and screw the shelves to the studs with 2-1/2-in. wood screws. Put a rubber bumper on the frame to protect the door.
Install a Shelf and Clothes Rod
Just go to your home center and get standard closet rod brackets, a closet rod and a precut 12-in.-deep melamine shelf. Also pick up some drywall anchors, or if you have concrete, some plastic anchors and a corresponding masonry bit. Fasten shelves to the wall and add the closet rod for instant laundry room storage.
