How to use this list
Measure all four sides of the mirror with a tape measure and verify corners with a combination square. Mark trim boards with a pencil, then cut moisture-resistant trim boards using a miter box and hand saw or miter saw. Sand cut edges with fine-grit sandpaper. Apply wood stain or paint, followed by a clear protective topcoat suitable for humid rooms, and allow finishes to dry as directed. Protect surrounding surfaces with painter's plastic sheeting. Apply mirror-safe construction adhesive with a caulk gun, place the trim, and hold it with painter's tape, clamps, or temporary support blocks while it cures.
