Mirrors — Types, Thickness and How to Choose

A mirror is the cheapest way to make an Indian flat feel bigger and one of the easiest things to get wrong: the backing decides whether it survives a bathroom, the thickness decides whether it stays flat, and the edge decides whether it is safe to touch. This is the national guide to how mirrors are actually made and specified here, and where to find the people who cut and fit them in your city. For what they cost, the Mirror Price Guide goes deeper than this page does.

The mirrors made in India

A mirror is float glass with a reflective coating on the back and protective layers over it. Almost everything that varies between one quote and another comes down to what that coating is, how thick the glass under it is, and what has been done to the edges.

Silver mirror

Float glass silvered on the back, sealed with a copper or copper-free layer and two coats of protective paint. It gives the brighter, truer reflection of the two common types and it holds up far better against moisture — which matters in any Indian bathroom and in coastal cities generally. It is the sensible default for anything you intend to keep for years.

Aluminium mirror

The same idea with an aluminium coating instead of silver. It costs less and reflects slightly darker and cooler, and its weakness is damp: moisture reaching the back edge attacks the coating, which is what causes the black creeping in from the edges of an old bathroom mirror. Reasonable in a dry bedroom or a budget fit-out, a false economy over a wash basin.

Bathroom and vanity mirrors

Damp air, splashing and cleaning chemicals all attack a mirror from the back and the edges, so this is where backing quality and a properly sealed edge earn their money. Fix with mirror clips, a channel or an adhesive sold as mirror-safe — ordinary silicone and solvent-based adhesives can attack the backing paint and stain the reflection permanently.

Wardrobe and full-length mirrors

A mirror on a wardrobe shutter or a full-length mirror in a walkway is somewhere a person can fall against, so it should carry a safety backing film — a polymer layer bonded to the rear that holds the pieces together if it breaks. Sliding wardrobe shutters in India typically take 5–6 mm mirror running in an aluminium system, and the system’s specification decides the exact thickness.

Gym, salon and studio mirrors

Large, uninterrupted and looked at all day, so flatness matters more here than anywhere else. These are usually 6 mm silver mirror with safety backing film, supported off the floor as well as fixed to the wall, and set out so the joints fall where they are least visible rather than wherever the sheet sizes happen to land.

LED, backlit and defogger mirrors

LEDs either wash the wall from behind the mirror or light an etched band on its face, and the practical planning item is a power point in the right place behind the mirror before the tiling goes on. Defogger pads — a thin heating film bonded to the back — keep a patch clear after a hot shower and need their own supply. Decide both early: retro-fitting either one means taking the mirror off the wall.

Before you order

  1. Ask which backing you are being quotedSilver or aluminium is the biggest real difference between two mirror quotes that look identical on paper, and it decides how the mirror ages in a damp room. Get it in writing rather than assuming.
  2. Match the thickness to the use, not the priceSmall framed pieces work in 4 mm, 5 mm is the usual wall and bathroom mirror, and 6 mm is what large, full-height and gym mirrors need to stay flat and be handled safely. Thin glass in a big sheet gives a wavy reflection that no fitting can correct.
  3. Name the edge finish in the enquiryA raw cut edge is sharp and has to be hidden in a frame or channel. A ground or arrised edge is safe to touch, a polished edge is glossy and meant to be seen, and a bevel is a shallow angled band ground round the perimeter, usually somewhere between 10 mm and 25 mm wide. Bevelling and polishing happen before delivery and cost more, so say which you want up front.
  4. Add safety backing wherever someone could fall into itWardrobe shutters, full-length mirrors, gym walls and anything at low level. The film holds the fragments together, it is inexpensive at the point of manufacture, and it cannot be added once the mirror is made.
  5. Plan the power before the mirrorLED mirrors, defoggers and touch switches all need a supply behind the glass, and once the wall is tiled the choice is a surface cable or a different mirror. Fix the mirror size and the socket position together.

Common questions

What thickness should a mirror be?

4 mm suits small framed pieces, 5 mm is the usual choice for a wall or bathroom mirror, and 6 mm is what large, full-height, gym and salon mirrors need to stay flat and be handled safely. Sliding wardrobe shutters normally take 5–6 mm mirror inside an aluminium system, where the system’s specification decides the exact number.

Silver or aluminium mirror — what is the difference?

The reflective coating on the back. Silver mirror reflects brighter and truer and resists moisture much better; aluminium mirror is cheaper and reflects slightly darker. In a bathroom or a coastal city the difference shows up as black creeping in from the edges of an aluminium mirror after a few years, so silver is worth the small extra for anything in a damp room.

Why do bathroom mirrors go black at the edges?

Moisture has reached the back of the mirror and attacked the coating. It is usually some combination of a lower-grade backing, an unsealed edge, an adhesive or silicone that was not mirror-safe, and a bathroom with no exhaust. Silver mirror with intact protective paint, a sealed edge and mirror-safe fixings is how you avoid it — once the blackening starts it cannot be reversed.

Can a mirror be toughened?

Not after it has been silvered — the coating and the backing paint would not survive the furnace, so an ordinary mirror is annealed glass and breaks into sharp pieces. The normal way to make a mirror safe in India is a safety backing film bonded to the rear, which holds the fragments in place. Ask for it on wardrobe shutters, full-length mirrors and gym walls.

What does a mirror cost?

It varies with the backing, the thickness, the edge finish and any LED or defogger, plus your city. The range shown on this page is aggregated from Glassy’s published city pages and is indicative only. The Mirror Price Guide breaks the pricing down properly, and a local quote against your actual sizes is the only real number.
