Since sharing a photo of our finished floor over a month ago, several readers have asked for more details about how we installed the transition pieces around the kitchen cork floor and the fireplace surround.
Eventually we plan to refinish the adjoining orange wood floors to better match the darker cork, so the finished look should be more cohesive — here’s a quick mock-up of the intended result (excuse the rough Photoshop):
Finding suitable transitions took some effort because our Lisbon Cork didn’t come with matching pieces. The store where we bought the cork recommended avoiding cork transitions because they’re not as durable as hardwood in high-traffic, impact-prone locations. Oak transitions were available at that store and could have been stained to match, but I found an engineered transition at Home Depot for about $27 that was already a very close match. Home Depot only stocked 48″ lengths, so I had to special order 72″ pieces and wait a few weeks for them to arrive. That’s why only shorter doorways got transitions when we first finished the floor in March; we finally finished the rest recently.
There aren’t many online tutorials specifically about installing transitions on cork floors, so I’ll describe the process we used. I wouldn’t claim it’s the only correct way, but it worked well for us. Since I didn’t photograph the original kitchen installation, I’ll walk through the steps we used on a similar doorway we completed last week.
We installed our floating cork floor over an existing subfloor because there was an asbestos liner under the vinyl tile. That left a slight step down — roughly 1/4″ to 1/2″ — between rooms. When adjacent floors are at different heights, you need a transition profile called a reducer. A reducer slopes gradually from the higher floor to the lower one to avoid a trip hazard. For the best visual result, avoid overly rounded profiles; a gentle slope looks more seamless.
After removing protective plastic from the engineered transitions, I marked a cutting line with a ballpoint pen to get the proper length and fit. I made the cuts on a miter saw for clean, straight edges.
Some sources recommend adhesive to secure transitions, but in our houses we’ve always nailed transitions in place, so that’s what we did again. We haven’t bought a nail gun yet, so I pre-set each nail by partially hammering it into the transition on a scrap block to start it, then positioned the piece and finished driving the nail. If you’re worried about splitting, pre-drilling a small pilot hole is another option.
For the doorway shown here, the drop was significant, so I let the small lip of the reducer sit on top of the cork to hold it steady while nailing the piece down.
After tapping the nails flush (we use an inexpensive nail punch to avoid surface dents), the result looked clean and professional. The raised edge is no longer a toe-stubbing hazard, and visually it finishes the space much better.
The hallway transition followed the same method, so I’ll skip those repetitive steps and describe how we handled the fireplace surround. The fireplace had raw edges and corners that required mitered cuts. I measured each side and cut 45-degree angles on a miter saw so the pieces would join neatly in the corners.
The fireplace area sits lower than the cork floor, so we used reducers there as well. This solution is temporary: once we choose tile we love, we’ll retile the surround which should raise the surface and allow us to remove these interim transitions for a flush, finished look.
For now, the transition trim works nicely and makes the spaces feel complete. Small finishing touches like this often make the biggest visual difference — no more raw edges, and the rooms finally read as finished.
Here’s a view from the hallway showing the new doorway transition and the fireplace beyond. And yes, that’s a large faux clam shell in the fireplace — a purchase we made for our collection. It’s oversized and dramatic, and surprisingly a few friends have asked where they can find one too.
Finally, here’s a shot of all three newly trimmed areas together. Ta-dah — the cork floor is officially trimmed and the space already feels more polished. We’re still using a placeholder rug for now, but it’s on the list to replace someday.
If you’ve installed transitions on cork or other uneven floors, what approaches worked for you? I was surprised there weren’t more examples specific to cork online, so I hope this walkthrough helps anyone tackling similar doorways.
