DIY Mudroom Tutorial

Build a custom built-in mudroom storage with our complete step by step tutorial. This storage is assembled in 3 separate pieces that are then attached together and mounted to the wall. We used 4 tools to complete this: table saw or circular saw, jig saw, pneumatic nail gun and a router.

Do you need more storage? Would like to create some built-in storage? Looking at building your own custom built-ins may seem like it’s just too hard, but it’s not. Just follow our steps and you too can have a custom built-in mudroom cabinet at a fraction of the cost of hiring a professional.

We chose MDF wood sheets for this project because it paints up great and when using a router you get better results, plywood tends to chip.

We mapped out how to cut our 4’ X 8’ sheets of MDF wood before heading to Home Depot. We had them cut the sheets of wood into 24” width pieces for the base unit and 13 3/4” width pieces for all of the upper pieces. Then we cut them to length for each piece at home with the table saw.

Let’s begin with the base unit. Cut the 24” wide MDF wood as follows: 

58 3/4” X 24”

57 1/4” X 24”

57 1/4” X 4”

Cut 3 pieces to 13 3/4”

Cut 2 pieces to 17 3/4”

We made a jig out of scrap wood to position the router. We used a framing square to make sure the jig was square. (Notice the dado grove in the jig that will line up where the dado will be cut.)

Router 3/8” deep with a 3/4” Dado router bit. On the 58 3/4” and 57 1/4” pieces. Refer to the diagram above for placement of dado cut.

Sand the edges of the three 13 3/4” pieces, this will make it easier to insert them into the dado.

Once all of the dados have been made it will be time to assemble the base unit.

Mark with a pencil the center of the dado on the other side of the wood. This is the line for brad placement.

Spread wood glue in the dado, place 13 3/4” piece in the dado, tap with a rubber mallet if necessary to get into position.

Place 3 brads along the pencil line, securing the piece in place, repeat for each section. Secure the 2 side pieces with glue and brads, as well as the 4” front base piece. (refer to the base diagram)

Now that one of the sections is finished, take a breather and admire your masterpiece! It will be a breeze to complete the other sections. The same methods are used just with different dimension.

For the coat hook section, cut the boards that are 13 3/4” wide as follows:

Cut 1  57 1/4” X 13 3/4”

Cut 2  44 1/8” X 13 3/4”

Cut 3  43 3/4” X 13 3/4”

Cut 2  5 1/2” X 57 1/4” pine boards 

Cut 8  5 1/2” X 11” pine boards 

Dado the 57 1/4” piece, the same way that the base unit was done, see diagram for placement.

Cut 2  5 1/2” pine boards to 57 1/4”. Using a jigsaw cut 2 notches in the 43 3/4” boards (1” X 5 1/2”) at the top and 13 1/2” from the top. These notches are where the pine board will be mounted (coat hooks will be mounted here.) This will also add stability to this piece. (Note that the back of this storage piece is just the wall that it is mounted to.)

Apply glue in the dado, place the 43 3/4” pieces in the dado, nail into place.

Add the side pieces (44 1/8”) glue and nail into position. Also nail into the 2.  1” X 5 1/2” boards. Nail into position the 11” X 5 1/2” boards at the top of each cubby section. See the diagram for placement.

Now that the 2nd section is completed it’s time to move on to the upper cubby section. (This is 2 separate pieces with 4 cubbies each.)  Cut the boards that are 13 3/4” wide as follows:

Cut 4  58 3/4” X 13 3/4”

Cut 6  14” X 13 3/4”

Cut 4. 13 1/4” X 13 3/4”

Dado the 58 3/4” pieces, the same way that the base was done, see diagram for placement.

Apply glue in the dados, insert 14” boards, nail into place as before.

Apple glue to the side pieces, nail into place as before.

These top cubbies are 2 separate pieces

Take a look at all 4 sections stacked together. Now we are ready to install this masterpiece!

The seat is made from a piece of oak plywood cut to 24” X 60 1/2”, a piece of 1” X 2” oak trim is glued and nailed around the edge. We applied a dark wax on it before we assembled the entire piece.

Next the oak seat is mounted to the bottom of the coat rack section with brads. Then that section is placed on top of the base and secured with a few brads from inside the base cubby up into the oak plywood.

Finally the upper cubbies are added and once again nailed together to the coat hook section and then the final cubby is mounted with brads to the other upper cubby section. Then once again, we used angle iron brackets to mount the top of the storage unit to the wall, into studs. 

We added 1" X 2" and 1" x 3" MDF molding over all of the edges to finish the built-in.

To mount the top header piece (11 1/4”) we attached some 2 X 4’s along the ceiling, lining up with the built-in. Cut the header to length then aligned it with the bottom edge of the top cubby and nailed into place. To complete the cabinet at the top we installed crown molding.

To finish the piece we caulked all the seams and filled in all the nail holes with putty and painted the piece. Finally we installed the hooks and could sit back and admire all our hard work!
