Have you ever worked on a space, and worked, and worked some more, only to feel like there was still something wrong with it. Making over a space takes a long time. One year we paint, next we add new window coverings, next we finally save up for that dream couch. We add one piece at a time until the room is finally finished. Well… I’m happy to say that my hallway is finally complete. The last piece of the puzzle was changing the interior door design – and it was probably one of the easiest changes in the space!

When we revealed our hallway decor early this year, did you notice that there weren’t many pictures with doors showing? lol. I was very strategic about my photo taking (which is hard considering there are three doors!). I loved the new decor, but I didn’t love the way it jived with the outdated wood doors throughout the hallway.

So I came up with a three step plan: Trim. Paint. Hardware. Pretty easy right? It really was! Above is the picture of my husband and I putting a rudimentary pattern on the doors. We had to test it out with masking tape before we bought the trim to see if we were going to like it or not!

How do you know your door is hollow core?

Before we get started, it’s important to know if your doors are hollow core! You can often just tap on the door to see if it sounds hollow or solid. However, this isn’t always the case. The more reliable method is to remove the door from the frame and if it’s easy to lift, then it’s likely a hollow core door, since hollow doors are much lighter than solid doors. Although, if you have solid wood doors, you can also easily do this project on wood doors too.

Hollow Core Door Makeover Tutorial

This door makeover was fast and easy to do, and only requires two tools. Here’s a step-by-step guide to making your own.

Six photos are shown which depict different stages of the renovation process for a hollow core door.

Plan Trim Location

Measure out where you want your trim and draw the outline right onto your doors. Our doors were actually all different sizes – and the knobs were at different heights! lol. But in general, we tried to line up the middle box with our new hardware, and we left a 4.5″ perimeter on all outer edges, and a 3.5″ space between the trim boxes.

Cut Trim Pieces

Once you have the design, cut your trim pieces at the right lengths and at 45 degree mitred angles at the corners to make the boxes.

Attach Trim

Attach your trim to the door with wood glue and a nail gun. Carefully wipe away any glue that seeps out with a damp paper towel.

Paint Doors

You all know how much I love Fusion Mineral Paint – so that’s what I used on these doors. They didn’t have the exact colour that I wanted, so I decided to mix colours a bit. I added 3 Midnight Blues and 2 Coal Blacks to create the perfect moody navy, almost black colour.

Add Hardware

I got these knobs and long plates from Nostalgic Hardware. They are part of the Fifth Avenue collection, and guys… look at the impact that new hardware can make! I mean… seriously gorgeous stuff!

Baaaahhhh! Look how different they are! All of the sudden my hallway looks finished and put together! I LOVE what the new and improved doors add to our space!

I can’t officially say the hallway is done because it will likely go through a few more transformations, but I’m so happy with how it looks right now! One more room down… a whole bunch more to go! lol.

      1. Hello, they doors look amazing. Can I ask is the bottom rectangle smaller than the top? I’m going to do this next week to my doors. Thanks

        1. Yes! The smaller one is smaller on my doors. I though it would look best if my handles were at the same level as my handles, which meant a smaller box on the bottom. Can’t wait to see what you do!

  1. oh … I love black doors!!
    I live in a residential area – Do I paint my white faux wood doors black? Just three in a short crooked hallway. Glossy Black or Matt? I want to update the space and this seems like an affordable bite.

  2. Wow, so impressed with the doors! Gutted I didn’t think of this before we bought all new doors!! The upholstered stool/bench next to the door…. I NEED the fabric! The navy and grey print! Where is it from? Thank you in advance! Xx

    1. You could, but we didn’t. All of our doors open to the wall so you don’t see much of them anyway. But we painted the inside the same colour obviously, lol.

  3. The doors inside the rooms… are those doors (closet or perhaps a bathroom door in the bedroom) painted the same color? If different, could you post a pic? I want my hallway doors to our bedrooms to be black but prefer the closet doors inside the room blend in more and remain white. Thoughts?

  4. I love the dark color on the door. What paint did you use? I want a deep bronze but I am not sure what pain is best. Thanks

  5. Hey there, your projects look great – thanks so much for sharing. I was wondering if you could please tell me more about your sliding door und how you attached it to the wall? Is that a DIY project as well? I’m still looking for a solution for our storeroom door.

  6. These look amazing! Did you have to sand the doors down before adding the molding and painting? How many coats of paint did the doors take?

  7. Absolutely beautiful! Everything goes together perfectly. May I ask where you found the hanging light and the gallery wall frames?
