We finally completed a small bathroom-door makeover that turned out to be far more eventful than we expected. Back in January we decided to keep the mirror on our master bedroom door (unlike the one on the guest bathroom door, which we removed). The plan was to give this mirror a thicker, more substantial frame so it wouldn’t look like a flimsy college mirror. We sketched the idea in January, but didn’t get around to finishing it until September.
The mirror had been useful for quick outfit checks, hair fixes, and the usual last-minute glances, but the plain plastic clips looked cheap.
After seeing other bloggers upgrade similar mirrors with trim, we thought it would be a straightforward project: remove the mirror, glue it back to avoid visible clips, cut molding with a miter saw, and glue the trim around the mirror. Simple, right?
To make the work easier, I took the door off its hinges so it could lie flat. Before removing the mirror, I traced its outline with a red pen so we could reposition it exactly where it had been. With the clips unscrewed, the mirror came off without trouble.
We picked up a mirror-specific adhesive (Liquid Nails Mirror Adhesive) at Lowe’s for a few dollars. It’s formulated to avoid damaging a mirror’s reflective backing, which is why we chose it over other adhesives. I lightly sanded the area on the door where the mirror would be attached to improve adhesion, per the product’s recommendation.
Because the adhesive had a strong smell, we worked in the sunroom. With the mirror adhesive applied, we pressed the mirror onto the door and let it cure for 72 hours as a first set time.
At Lowe’s we initially bought a narrow trim that seemed suitable; its groove fit over the mirror edge. After measuring, cutting, and fitting those pieces, we realized the narrow trim didn’t improve the mirror’s appearance at all. It still read as a cheap mirror.
We returned to Lowe’s and found a heavier trim with a wider face and enough lip to sit over the mirror edge. The new trim was nearly three inches wide—large enough to make a visual difference but not so wide that it would hit the doorknob. I used painter’s tape to mark the mirror’s beveled corner line so I could make precise 45-degree miter cuts on the trim.
After cutting and dry-fitting the pieces, I used heavy-duty adhesive to attach the trim to the door. Normally I default to nails or screws, but I wanted a cleaner look and didn’t want visible fasteners near the mirror. I applied a thin bead of adhesive to the door-facing side of each trim piece, set them in place, and taped them down to prevent shifting while the glue cured.
However, after letting everything dry for a day and re-hanging the door, the mirror slipped off the door soon after a shower and knocked off the bottom piece of trim. Fortunately the other three trim pieces held it back, and the mirror only suffered a chipped corner that the trim would hide. The crash was alarming and forced us to reconsider our approach.
Reviewing the adhesive instructions revealed a few key points we had missed: the product advises using a permanent support system and allowing a full week for the adhesive to cure. We hadn’t provided any permanent support and had reinstalled the door too soon.
For the second attempt, I followed the instructions carefully. I applied the adhesive directly to the mirror in smaller, more evenly distributed globs and added crossing lines to spread the bond more effectively. To provide permanent support without the old plastic clips—which would have interfered with the trim—I added small finishing nails around the mirror’s edge. The nail heads act as ledges the mirror can rest against, working in combination with the adhesive and trim to prevent slippage.
We let the mirror cure for seven full days before re-hanging the door, even though that meant a week without a master bathroom door. After the seven-day set, I tested the door by leaving it upright overnight on a soft surface to ensure the mirror would stay in place. It passed the test, so I glued the trim back on and let that set flat for several nights before final reinstallation.
Now that the project is complete, the trimmed mirror is a subtle but effective upgrade. The white trim on the white door doesn’t dramatically pop in photos, but in person it adds a clean, layered architectural detail that complements the nearby larger mirror. The goal was to refine the raw mirror edges, not to create a competing focal point, and the final result accomplishes that quietly.
In the end we spent about $12 on the thicker trim and roughly $5 on adhesive, so the project cost around $17—unless you, like us, initially buy an ineffective trim and need to replace it. Fortunately, we later learned that many stores will accept returns of cut trim over 12 inches, so we may be able to get back the cost of the first, too-narrow pieces.
It wasn’t the fastest or cleanest DIY, but it’s done: the mirror is secure, the plastic clips are gone, and our daughter is happily admiring herself again. The door has survived multiple showers and a week of testing without incident—success, at least for now. If anything changes, we’ll share what we learned.
