Everyone has seen an old mirror go black at the corners. That is not dirt and it will not clean off. It is the silver behind the glass giving up where moisture reached a cut edge, and it is the reason a mirror for a bathroom is a different piece of glass than one for a hallway. We cut ours in the Lodi shop, finish the edges, and hang them so the back of the glass stays out of trouble.
A mirror is glass with a silvered coating and a protective backing, and nearly everything that goes wrong with one starts back there rather than on the face you look into. Moisture finds a cut edge, works its way under the coating, and the black creeps inward a fraction at a time. So edge treatment on a bathroom mirror is not purely a matter of looks. Edges are cut, seamed and finished in our shop so no raw or chipped edge is left open, and the piece is hung with air behind it instead of pressed flat to a wall that gets steamed twice a day.
The front of the glass is where the rest of it gets decided, and that begins with what the piece is actually for. A vanity mirror can stop at the backsplash and the light fixture, or carry the whole width of the counter and make a small room read wider. A full-length panel needs a wall somebody can stand back from. A mirror wall is sized to the room instead of to a stock sheet, and when one piece would never make it up the stairs, the run gets split into panels with the seams placed on purpose rather than left to land wherever they fall. All of that is settled with a tape in the room, before any glass is cut.
In a lot of older baths the mirror is not really a mirror, it is the door of a steel cabinet recessed into the wall. People are usually finished with them: the shelves rust, the door never sat flush, and the opening is a size nobody builds for any more. Moving to one clean piece of glass is the obvious upgrade, and it arrives with one honest complication. Behind that cabinet is a hole in the wall, and closing it is plaster work rather than glass work. That part is not ours to do.
Which leaves two routes, and the measure is where you pick one. Either the recess gets closed up by whoever handles your walls and we come afterward to a flat, finished surface, which gives you the largest mirror the room can carry, or the glass is sized and set so the cabinet stays exactly where it is and the mirror works around it. Neither one is wrong, and neither costs you the other later. What matters is deciding before anything is cut, because a mirror is made to one set of numbers and there is no trimming it later.

Moisture reached the cut edge and got in under the silvering. Once that starts it keeps going, slowly, and nothing will clean it off, because the damage sits behind the glass rather than on it. Bathrooms do it fastest, and fastest of all where a mirror was bedded flat to the wall with no air behind it and no finished edge. A new piece with properly finished edges, hung on fixings with a gap behind it, is a different proposition.
Thicker than the sheets sold in a box, in most cases. Thickness is what keeps a long piece flat, and flatness is what keeps a reflection from wandering at the ends. A small vanity mirror does not need much. A run covering most of a wall does, both for the reflection and because that glass has to survive being carried and lifted. We size the thickness to the piece instead of using one number for everything.
That is mostly an edge decision. A bevel puts a visible chamfer around the perimeter, and it lines up with the way older rooms are detailed, so the glass reads as a piece of furniture rather than a surface. A polished edge is quieter and suits a bathroom where the mirror runs to a backsplash. In a room with strong mouldings we would usually show you the bevel first and let you decide against it.
Placement and airflow do most of it. Glass set slightly off the wall on solid fixings lets air move behind it, which matters in a room that gets steamed twice a day. Beyond that it is ventilation, and a fan run during and after a shower does more than any treatment. If the bathroom has a real steam problem, mention it when we measure, because it changes where the piece goes and how it gets backed.
A wall that cannot carry the weight, and a surface that will not stay put. Plaster over lath is fine when the fixings reach framing behind it, which is why we find that framing before hanging anything heavy. Tile can be worked with. What we avoid is trusting adhesive on a surface that may let go, or covering something that needs access later, such as a shutoff or an access panel.
