Let’s talk about a small mirror makeover that turned into a series of unexpected hiccups. Back in January we decided the mirror on our master bathroom door could stay (unlike the one on the guest bathroom door that we removed because it showed the toilet user their entire body). We agreed the master bedroom mirror could remain only if we built a thicker frame around it to give it more presence—so it wouldn’t look like one of those flimsy college mirrors. The idea was simple, but we didn’t actually get around to it until September.
The mirror had been very useful for checking outfits and fixing hair, but the basic plastic clips and exposed edge weren’t attractive. We’d seen other DIYers give mirrors a nicer finish using trim, so we thought it would be an easy upgrade.
First I removed the door from its hinges to lay it flat and planned the steps: remove the mirror, reattach it with mirror-safe adhesive so the clips wouldn’t interfere, cut molding on a miter saw, then glue the trim around the mirror. To make sure we’d glue the mirror back in the correct position, I traced the mirror outline on the door with a red pen. The plastic clips came off easily and the mirror lifted free.
We chose a mirror-safe adhesive from Lowe’s—Liquid Nails Mirror Adhesive—because it’s formulated not to damage the reflective backing. Before gluing, we sanded the door where the mirror would go to roughen the painted surface, which the adhesive instructions recommended. Since the adhesive had a strong odor, we moved the operation to the sunroom and applied the recommended blobs of adhesive to the back of the mirror, then pressed it into place and left it to cure for 72 hours.
For the first trim attempt we bought beadboard-style molding with a groove that would sit over the edge of the mirror. After measuring and cutting the pieces on the miter saw, we stepped back before installing them and realized the narrow trim didn’t improve the look—it just made the mirror look even more like a cheap college-style mirror. So we returned to the store and chose a heavier trim with a wider face—about three inches—so it would read as a proper frame without hitting the doorknob.
To match the mirror’s beveled corner, I used painter’s tape to extend the bevel line and marked 45-degree cuts on the trim. After cutting and test-fitting the mitered corners, I used heavy-duty liquid adhesive to glue the trim pieces to the door. I typically prefer mechanical fasteners, but I didn’t want to screw or nail right next to the mirror and the adhesive claimed it could handle the job.
I applied a thin bead of adhesive to the back of each trim piece, positioned everything carefully, and taped the pieces in place to keep them from shifting during curing. After a day of drying, we reinstalled the door and celebrated… until moments after my shower the mirror slid down and off the door, breaking off the bottom trim piece. The other three trim pieces held the mirror upright, so the only visible damage was a small chipped corner that the trim would hide, but the noise and the surprise were alarming.
Going back through the adhesive instructions revealed the problem: the product warned not to use it without a permanent support system, and it recommended applying the adhesive to the mirror backing, allowing a full week to cure. We hadn’t followed that guidance closely enough the first time.
For the second attempt we applied the adhesive directly to the mirror in generous, appropriately sized beads and added some crisscross lines for better coverage. Instead of reinstalling the original clips, I added small finishing nails around the edges of the mirror to act as a subtle mechanical stop. The nail heads sit against the mirror and help prevent downward movement while remaining inconspicuous under the trim.
Then we committed to a full seven days for the adhesive to cure. I know that sounds extreme, but it meant another week living without a door on the master bathroom—worth it to avoid another failure. On night seven we stood the door upright on a pillow for an overnight test; the mirror stayed put. Confident it was secure, I glued the trim back on, let it sit flat for several more days, and finally rehung the door.
The finished result is a subtle, cleaner look: white trim on a white door provides a layered architectural detail that reads better in person than in photos. The goal was never to draw attention away from other focal pieces in the room, but simply to hide the raw mirror edge and eliminate the ugly plastic clips. It accomplished that quietly and effectively.
The total cost was modest. The second, thicker trim cost about $12 and the mirror adhesive brings the project total to roughly $17, assuming you don’t have to replace any mistakenly purchased narrow trim (we plan to return ours if possible). After all the effort and patience, it feels good to have the project finished, privacy restored, and those plastic clips out of sight—plus one less thing on our to-do list for the doorknob update.
Have you tackled a supposedly “easy” DIY that turned out harder than expected? We were relieved when the door survived multiple steamy showers without incident. For now, the trimmed mirror is holding up and the upgrade—though subtle—is exactly what we wanted.
