Learn how to design your living room when you have a corner-mounted TV

Have you ever wondered how to design once your TV is corner-mounted? Well, that was our problem…

So, of course, we were looking for a DIY corner shelving solution!

We recently wanted to update our living room space after our amazing porch addition happened. Our living room slowing has been getting a facelift, from a newly painted fireplace mantel to simply moving some furniture around.

When we mounted our large TV in the corner, we had to really come up with a DIY corner shelf that would allow us to hold our cable box and DVD player…

(yes my kids still love getting DVDs from the library) without seeing all the cords all over the place.

Corner shelf ideas

Here are a few corner shelves that I looked at purchasing, but I just couldn’t bring myself to purchase them since I knew we could make one ourselves. Feel free to click on the image to shop for these shelves!

DIY shelving project for the win!

After searching for corner shelf ideas, there just wasn’t anything I thought was worth buying. Either I loved the look, but didn’t want to pay the price. Or there was just not a shelf design that was going to work for us.

We ABSOLUTELY loved our DIY industrial shelves we did our small bathroom makeover, that we knew we wanted to repeat the same look but for a DIY TV shelf.

Factors to consider when having a corner-mounted TV

Placement of electrical outlets

How many cords will you need to run in your wall? Do you care if you see a cord?

Will there be any furniture underneath your corner or regular mounted TV?

What do you need next to your TV? Cable box? DVD players? Gaming systems?

Here our considerations for a corner mount TV and corner shelf in our living room

Due to the positioning of our windows and new sliding doors that we love, we had to mount our tv in the corner.

In my opinion, a regular wall mounted tv and regular shelf would have been easier to build and put up, but it just didn’t work with our room. We bought this heavy-duty mount and had an electrician move our electrical outlet so that it would be behind the TV.

Did you know????

The standard height to put the outlet was 6 feet? I swear I thought it was too high, but then once the TV was mounted and tilted a little forward it didn’t matter.

How to hide your cable box and other cords?

In addition to having the electrical outlet moved, we also had our television cable moved up so that the cable jack would be 6 inches below the tv and where we would need to put our corner shelf under our television. This was so that the cable wire would come right out of the wall and directly into the cable box. 

We probably could have done this ourselves, but we had workers and an electrician already at our house for other projects so it just made sense for them to complete this for us.

You then have to run the power cord and HDMI cord through a bypass in the wall.

This was a little difficult to do, but I love that all the wires were sent there and hidden out of view. 

Here is an example of the bypass we used to help hide out cables. Feel free to click on the picture to learn more about it on Amazon.

And by a little difficult, I mean a total pain to awkwardly be behind your corner mounted tv hoping wires don’t get all mixed up in your wall!

You may also want to consider buying a shorter HDMI cord, depending on much space you have to cover. I had to use a twisty tie in the back of my cable box to hide the extra cable cords.

What if you don’t want the tv cords to go through the wall?

I did consider painting a small piece of PVC pipe the same color as our wall (SW Livable Green). However, there is also this product that fits nicely in the corner that probably would work well with a corner-mounted tv and corner shelf. The corner shelf really does hide a lot!

Tip for when hiding wires from your mounted tv

Keep a metal sturdy wire in the bypass and wiggle it around can really help you get the cords from the top to the bottom. You can pull out the wire once you have gotten all of your cords through. You have to drop them down, don’t try to push them up through the bypass.

Pin for later!

DIY Corner Shelf: Making a TV shelf we would LOVE!

If you look up corner shelving units, there really wasn’t anything I was finding that was worth the money or that we thought would work for the corner of our living room. 

It is so amazing when your love for DIY allows you to make what you can’t seem to find. We even had leftover wood from a different project that we used to make the triangular corner tv shelf!

Oh and by the way…

Since we had leftover wood, this project is part of a DIY project challenge that other amazing bloggers participate in. The original piece of wood was a 10 foot long 1″ x 8″ piece of poplar.

For the DIY Project Challenge, each month there is a different theme. This month we needed to use wood we had lying around, so this DIY corner shelf for under our television was perfect to add the challenge.

How to make a corner shelf?

1. Use a miter saw to cut a 45-degree angle. The angle carries through two (2) pieces of wood in our case to make appx. a 20″ wide shelf. Depending on the thickness of the width of wood the number of cuts will vary.

our work table was our DIY outdoor table that we made from leftover composite decking!

2. Glue wood together with wood glue. My husband recommended this brand. After gluing, clamp the wood together using C clamps.

Corner Shelf Tip Alert: Use Wax paper with Clamps!!!

A trick is to put wax paper between the bottom of the clamp and the bottom of the C clamp so it will stop an excess glue from sticking to the clamp.

3. Sand corner shelf using 80 and 120 grit sandpaper.

4. Stain DIY corner shelf after sanding. We used our favorite stain color! I love the richness and depth of this color.

5. We loved the look of these industrial shelves in our bathroom makeover, that we knew we wanted to use these flanges and pipes again. So in the online cart they went…

6. When installing the shelves, make sure you attach the flanges to studs, especially if you plan on placing anything heavy on the corner shelf. We used drywall supports before screwing in the flanges and a level to make sure our measurements were correct.

7. Screw-in both flanges and pipes. Check they are level before attaching the stained triangular wood shelf.

Notice in the picture how you can see the cord bypass below the TV. The HDMI cord and power cord were just taped out of the way until we could get the cable box set up.

      Thanks, Kippi! I love that I cannot see the cords from our corner-mounted TV! I loved being in this DIY challenge again. Such a great group of DIY bloggers!

  • Jenn Summers

    This is such a cute idea for a corner shelf! You would not believe how hard it is to find flanges here! I searched and searched when I was wanting to make a barn door and could not find them anywhere, sigh. Love the 3-speed brushless impact I just got one for my birthday! Eek!

  • Karletta

    The shelf looks great, and I’ll exactly where to come when it’s time to mount one myself. Highlight for me: “How to hide your cable box and other cords?” I don’t like the look of untidy cords adorning a space.
