Ikea Besta Hack: Turn Them Into Built-Ins: a house log

Built Furniture

Want to turn Ikea Besta cabinets into custom built-ins? We made 3 plain “hacks” to make our Betas look like higher-end custom storage with a high-end price tag. So now we have extra storage and bonus architectural detail in our bedroom.

Built-in storage is helpful anywhere, but especially in a smaller home like ours. We have brought in built-in Pax closets in our bedroom, a custom desk & bookcase to our son’s room, and the wall-to-wall media cabinet in our family room. So when we needed a solution to the empty spots next to our fireplace, we knew more built-ins were in order.

Why Choose Ikea Bestas?

The fireplace you see above is directly across from our bed. It is come a long way from when we first dropped some random furniture beside it after we moved in (seen below). We knew the space had plenty of potential due to its inherent symmetry and the recessed areas that begged for some sort of built-in.

Ikea sells a 47″ wide Besta cabinet that nearly perfectly fills the 50″ space on the left side. Paired with some basic legs, the height of a Besta also fit perfectly under each window. So they were a no-brainer starting place for these built-ins.

We in fact picked up the cabinets way back in late 2020, which is why you might’ve noticed them in the background of our holiday decor post that year. This is a photo from back then, minus the actual holiday decor:

At this point, they were not truly “built-in.”They were simply sitting there. But we were so grateful to have earned more concealed storage that we did not rush into the rest of the makeover. We were busying updating the fireplace instead.

Over the next year, we got them looking a lot more custom. And now we cannot truly even picture them looking like the two photos above.

How We Hacked Our Ikea Bestas

There are plenty of ways you can customize or “hack” Ikea pieces to make them your own – paint, add trim, install hardware, wallpaper them, etc. But for these, we truly simply did three plain things to make them look more built-in:

  1. Brought in filler trim on the sides
  2. Brought in baseboard
  3. Brought in a butcher block counter

Besta Hack #1: Add Side Filler Pieces

We have covered how to add filler trim to Ikea pieces a few times for other built-in projects. So check out our son’s nursery built-ins or our walk-in Ikea closet for a more specific step-by-step on that process. It is something anyone can do as long as you have a saw, screwdriver, and nail gun. You are simply attaching small pieces of wood (like a 1×2″) to fill gaps between the Besta and the wall.

Side By Side Of Adding Filler Pieces To Ikea Furniture

The main thing to remember – which I labeled below when building in our last closet – is that you may need to account for TWO LAYERS of filler trim. A back layer will be secured into the side of the cabinet box AND a front layer will sit on top of it, looking flush with your door.

That way when the doors are closed, it should look something like this – with the filler piece flush with the front of our door.

When painted to match – we used Sherwin-Williams Pure White – the filler pieces will assist your Besta look like it a custom wall-to-wall cabinet.

Besta Hack #2: Add Baseboard

To add the baseboard to a Besta, you will want to match the same baseboard and quarter-round trim that already exists in your room. That will assist your Ikea piece look more like built-in architecture in the room.

We nailed our baseboard to the stock block legs that come with the Besta. The only problem was this made the baseboard stick out a bit too far past the doors. One option would have been to float the Besta on the wall and then reattach the legs or some other wood blocking further back. We chose to use a thin strip of plywood instead of actual baseboard instead. This gave us the depth we hoped and – once we nailed quarter round in and painted everything white – you’d never know it is not actual baseboard.

Besta Hack #3: Add Counters

Adding a countertop is a strong way to upgrade the basic white top of a Besta cabinet. We particularly enjoy the warm contrast of this butcher block countertop. We have used it in two other projects – our utility closet makeover and our Hands-on wood nightstands – so it was an obvious choice for us. We enjoy how chunky it is and how the color works so nicely with our floors.

We used our circular saw to cut it to size and then sealed it with a coat of cutting board oil, both to protect it and to bring out the color a bit. It dries much lighter than it looks below, so do not panic.

To attach it we simply screwed up through the top of the Besta right into the wood. It is fairly heavy so it stayed in place well on its own, but the screws make sure it will not drift over time. Simply make sure your screws do not come through the top!

We also drilled holes in the counter for our lamp cord to reach the plugs behind each Besta. We picked up a special 2″ drill bit to make the hole, and it took some patience to get all of the way through the butcher block AND the top of the Besta. Then capped it off with these brass desk grommets to make it look tidy and professional. They go in with the light tap of a rubber mallet.

The cords simply snake into the Besta and sit unceremoniously on one of the shelves. You can also see how we cut out a hole in the back of the Besta to access the outlet. It is not quite fairly, but who cares? It is hidden inside the cabinet!

Speaking of the inside of our cabinets…

What We Store In Them

Adding and “hacking” these cabinets was a game changer for our bedroom storage. Sherry even filmed a swift video to give you a closer look at how they look all upgraded in our space & to show you what is inside (including more about how we wired up the lamps):

Note: You can also watch this video on YouTube.

The Ikea cabinet on the right side stores a bunch of miscellaneous stuff like spare paint (as you can see above in the outlet photo). Since the video was filmed, we have done some rearranging and now one side is our official family game cabinet.

The cabinet on the left still contains a bunch of overflow books, gift bags & tissue paper, plus some overflow candles, vases, and other knick-knacks that Sherry likes to rotate in and out. I know it looks a little tough to get to behind the table but trust us that it is no problem.

The stuff in that cabinet are not things we need every day (or week, or month!) so we do not need to get back there quite frequently anyway.

Update: More Ikea Besta Cabinets

Another update is that since writing this post we have Brought in MORE CABINETS. As explained further in this shelving post, we enjoyed the Besta storage so much that we extended it along the rest of the wall in this room. So we in short got to repeat all of these hacks again: adding filler pieces, adding baseboard, and adding more countertop.

Overall, we are so glad with how they turned out, especially considering how plain our “hacks” were to make them feel like custom built-ins.

Thanks to these built-in Besta cabinets, the storage in this room is truly maximized. And we managed to make it look fairly good in the process too!
