A Rubbermaid storage shed adds extra outdoor storage space to your yard, all in a maintenance-free building that stands up to the elements. Assembling your Rubbermaid storage shed is simple with a few tools and some time. Before you start assembling, check your local homeowners' association or building authority for restrictions or permissions needed to add an outdoor building to your property.

Foundation Options

Your storage shed will need a flat, level spot with good drainage. There are a few options for a shed foundation. Rubbermaid recommends concrete, a patio or a treated-wood platform. For smaller sheds, leveling the ground with gravel or pavers may do the trick. Kits for premade shed platforms can be found online or at home improvement stores, and simple instructions on how to build a wooden platform are offered on multiple sites online. Prior to laying your foundation, the ground must be dry and level. Even a premade kit won't work if the ground isn't level.

All About the Floor Base

The floor base will come with recessed anchor locations that can be used to anchor the shed floor to a wooden foundation. Spread out the base of the floor over the foundation. Use a rubber mallet and screwdriver to punch out the screw holes in the floor and knock out the tabs for the door hinge. Insert the anchors if needed. On the front floor, drill pilot holes through the surface where indicated. Install all screws into the pilot holes.

Wall Panels

Use your screwdriver again to punch out the screw holes at the top of the panels. Align the panel with the floor and snap the panel into position. For the next wall panel, repeat the hole punching and align over the floor. The wall panel will slide into the previous wall panel's dovetails before snapping into place. Repeat with the next wall panels, this time aligning both the dovetails and the lap joints. The walls should fit together like a puzzle. Use dish soap for lubrication if the panels aren't sliding into place.

Wall Connectors

The wall connector will have an "up" sign on it indicating which way it should be installed. This will click into place and connect the right back and left back panels. There will be around five of these wall connectors depending on the size of your shed. Follow the connector instructions and insert the connectors, sliding down until they make a clicking sound. Repeat this step for the side wall panels.

Pilot Holes

The front wall panels will need a pilot hole drilled in when inserting the wall. There should be about eight pilot holes in total that will be used to secure the walls to the floor. Once all of the walls are put up, make sure the pilot holes are clear for screws. Screws should be inserted last in case anything needs to be shifted after the roof and door are attached.

Raise the Roof

Align the roof panel over the shed. Some sheds have more than one roof panel, so in this case, attach one panel at a time and repeat the steps as needed. The overlapping edge of the roof should point to the back of the shed. Align the tongues of the walls to fit into the grooves in the roof panel. Ensure that the roof brace is aligned in its proper place with the wall and lower the roof into place. Hold the edge of the roof down and install screws, starting from the corners and working your way up alternating sides. Once this is done, step inside the shed and insert the roof screws in the interior and in the roof brace. Do not tighten all screws until the door is in place.

Attach Door and Tighten Screws

The left and right doors will fit securely into the hinge openings in the front floor. Align the sides and gently insert the door into the hinge sockets. Raise the front edge of the roof to install the door hinge pins and then tighten the roof screws. Finish your project by tightening all the screws throughout the floor and roof, ensuring each is flush with the shed. The door handle and lock clasp will screw into the appropriate holes in the door. Congrats! Your shed is ready to use.
