When we moved into our home, we had this huge family room and only this teeny tiny rustic tv stand / bureau to place our television on. We wanted more storage in the room for video games, movies, and more. But the icky bookshelves we put up on either side of the bureau were pretty ugly.

Fortunately, Pinterest came to the rescue. I saw these built-ins from by and we decided to tackle something similar for our space. Our in-laws came up so we decided to get started on this project while they were around to watch the kiddos for a bit.

Update from 1/25/20: We sold our home and moved so we HAD to recreate this project. For our second attempt at this, we didn’t build a base- instead our living room cabinet storage system is “floating” with legs for additional support. We also used pine bookshelves instead of MDF at our new home.

Here’s a product you might be interested in from my store. Keep scrolling for the tutorial!

How to Install Wall Cabinets as Base Cabinets

Before we get started, you should be clear on the difference between wall cabinets and base cabinets. Basically, wall cabinets are cabinets that are installed (usually against the wall) at eye level. Base cabinets are cabinets that sit below a countertop, closer to the ground.

Here’s some more information on the differences:

Base CabinetsWall Cabinets
Sit below a countertop with extra space
at the bottom of the cabinet (known as toe-kick space)
No extra base at the bottom
Usually between 24-30 inches deepShallower, only about 12-18 inches deep

Now, since we were able to find wall cabinets at a reasonable price (see below for costs and supplies), I wanted to make them work as base cabinets for our entertainment center. You can easily do this, too, with a few changes.


Our wall is 164″ long so we decided upon the following for the base: (2) 12″w cabinets, (2) 36″ w, and (2) 30″ w. Keep in mind that these are the wall cabinets you buy to put above in a kitchen- not base cabinets. Those would have taken up more floor space and made the space feel smaller.

Here’s the order list for our project and costs:

  • 2x 12″w cabinets (12×30″): $101.82
  • 2x 36″w cabinets (36×30″): $189.92
  • 2x 30″w cabinets (30×30″): $164.47
  • 8″ Steel Molding Bar: $9.77
  • Pro Doweling Jig: $28.98
  • Box of Screws: $5.58
  • End Piece to Match Cabinets (covers the end that shows so it doesn’t look icky): $7
  • 21/32″x16″x3′ Wood (Listed at PNT on receipt, 5 @ $7.90): $39.50
  • 1x4x8′ Top Choice Wood for Countertop (Listed as Whtwd on receipt, 4 @ $5.68): $22.72

You can shop Home Depot’s upper cabinets that are unfinished here.

Here’s how I saved money on the project- I planned to use stock unfinished cabinets from Lowes. I bought a Lowe’s coupon off eBay that could be used online. Then I clicked through to the Lowe’s site from Rakuten and scheduled my order for pickup at Lowe’s.


If you don’t have any tools, this Ryobi kit includes a brad nailer, some batteries, an impact driver, a circular saw, and a drill.

The cabinets fit in our minivan with the seats out. I wasn’t so sure about this whole minivan thing (I’m a big fan of our Hybrid Prius and the 44MPG I get in it), but it sure comes in handy for actually putting something besides the kids in the car!

Marking the Floor for the Base

Before we bought everything, my mother-in-law suggested we use masking tape to show where everything would go on the floor. This helped a lot while we were doing the whole process.

We had to remove the molding around the area we were installing the built-in cabinets. We opted to remove the molding for just the laminate floors and leave the white molding and work around it.

My husband then calculated measurements to build a base for the cabinets and used dowels (using a pro-doweling kit he found) to combine pieces so they were long enough. I think in the original tutorial she built a separate base for each set of cabinets, but he built one big base instead.

For the front of the base, he cut a slanted edge on two boards (because he didn’t have one board long enough for the whole base) so he could combine them without having as rough of an edge like if he’d just combined them with two vertical cuts.

Ugh- looking back at this project, a miter saw would’ve been REALLY helpful. I can’t believe we used a hand saw for this! Back when we didn’t have as many tools, things took us quite a bit longer. Sometimes having the right equipment is REALLY nice.

He did this. I have no idea how it looks so perfect or what he did here.

But it fits to wall nicer without him needing to remove the baseboard.
Assembling cabinets

Once the base was on, Daddy B started installing the cabinets which screw into each other and the wall. He made sure to measure out where the outlets were and cut a spot out for them to come through. We will also cut a hole in the top of the cabinet and the countertop to run cords through for the electronics.

And here we are, all set up with the cabinets screwed together and mounted on the base. We didn’t use glue on the base to hold the cabinets on. Hoping that wasn’t a mistake. When we built this base, we were pretty huge amateurs to woodworking, but we slowly learned and Daddy B was very good at figuring this stuff out. If you are a new woodworker, be sure and check out the woodworking archives so you can learn more, too.
