A mirror splashback is a panel of toughened safety glass with a reflective coating on the back, fixed to the wall behind a benchtop or cooktop. It bounces light around the kitchen, makes a small space feel larger, and wipes clean like glass. It suits renovators who want a brighter kitchen and accept that a mirror shows smudges more readily than coloured glass.
This guide covers what affects the cost of a mirror splashback in Sydney, the differences between toughened, tinted, and antique mirrors, how mirrors compare with a coloured glass splashback, the rules for gas cooktops, and how to clean one without damaging the backing.
What is a Mirror Splashback?
A mirror splashback is a made-to-measure glass panel with a metallic reflective layer, usually silver, applied to the back and sealed with protective paint. For kitchens, the glass is toughened before the mirror coating goes on, because a finished mirror can’t be toughened afterwards. The result looks like a wall mirror but is built to withstand heat, steam, and splashes.
Mirror splashbacks are custom-cut to your wall, with cut-outs for power points and switches, and are made from toughened safety glass. Common finishes include clear (silver), grey and bronze, with antique and veined effects available from some suppliers.
They work anywhere you would use tiles or coloured glass splashbacks: behind kitchen benches, in butler’s pantries, laundries and bathrooms, and in covered outdoor kitchens. Their reflectivity is most useful in narrow galley kitchens, apartments and rooms with limited natural light.
Toughened vs Antique vs Tinted Mirror Splashbacks
The right mirror depends on where the panel sits and the look you want. Standard toughened silver mirror is the default for most kitchens. Tinted mirror softens the reflection. Antique mirror creates a vintage, mottled effect, but needs care in hot zones unless a toughened version is specified.
| Mirror type | Look | Behind a cooktop? | Shows smudges | Best for |
| Toughened silver (clear) mirror | Bright, true reflection | Yes, when toughened and installed to gas and appliance requirements | Most visible | Small or dark kitchens that need maximum light |
| Tinted grey or bronze mirror | Softer, darker reflection with a cool (grey) or warm (bronze) cast | Yes, when toughened | Less obvious than silver | Contemporary, moody or warm timber kitchens |
| Antique or veined mirror | Aged, mottled, partly reflective | Only if the product is confirmed as toughened safety glass | Least obvious | Butler’s pantries, bars, feature walls and sink runs |
Toughened silver mirror
This is the classic option. Because it reflects the most light, it has the biggest effect on brightness and the sense of space. It also reflects everything in front of it, including benchtop clutter, so it suits tidy, minimalist kitchens.
Tinted grey and bronze mirror
A tinted mirror uses tinted glass behind the reflective layer. Grey reads as modern and pairs well with black tapware and dark cabinetry. Bronze adds warmth and suits timber, brass and natural stone. Because the reflection is dimmer, fingerprints and watermarks tend to be less noticeable than on silver. For more on finishes and shapes, see our guide to custom mirror sizes and styles.
Antique and veined mirror
A traditional antique mirror is produced by treating the silver layer to create a weathered pattern. Most antique mirrors are made of standard (annealed) glass, which is not suitable directly behind a cooktop. Some manufacturers now make antique-effect mirrors on toughened glass. If you want an antique mirror near heat, ask for written confirmation that the product is made of toughened safety glass.
How Much Does a Mirror Splashback Cost?
There is no set price for a mirror splashback, because each panel is made to fit a specific wall. Your price depends mainly on the wall size, the mirror finish, and the number of cut-outs. For an accurate figure for your kitchen, request a free, no-obligation quote or call 1800 452 946.
The main cost drivers are:
- Area: Splashbacks are priced by the square metre, so a full-height wall costs more than a standard 600 mm strip.
- Mirror finishes: silver, grey, bronze, and antique finishes are priced differently, so ask for a quote for each option you’re considering.
- Cut-outs and holes: each power point, switch or tap hole adds fabrication time.
- Number of panels: long or L-shaped runs may need joins, adding measuring and handling.
- Wall preparation: removing old tiles and patching or fitting a non-combustible backing board behind a gas cooktop adds labour and materials.
- Access: high walls, tight apartments and upper-floor deliveries can affect installation time.
Ask for a written, itemised quote that states the glass type and thickness, the number of cut-outs and whether wall preparation is included.
Mirror Splashback vs Glass Splashback
Mirror and coloured glass splashbacks are both toughened glass, so they share the same smooth, grout-free surface and heat resistance. The difference is mostly appearance and day-to-day upkeep. Mirror maximises light; coloured glass hides marks better and offers almost unlimited colour choice.
| Factor | Mirror splashback | Coloured glass splashback |
| Appearance | Reflective; makes the room feel larger | Solid colour; can be matched to paint colours |
| Light | Reflects the most light | Glossy, but reflects less |
| Smudges and splashes | More visible, especially on silver | Less visible on mid-tone colours |
| What it reflects | Benchtop items, rangehood underside, opposite wall | Soft gloss only |
| Heat behind a cooktop | Suitable when toughened and installed to requirements | Suitable when toughened and installed to requirements |
| Edge care | Edges must stay sealed and dry to protect the backing | Painted backing; less sensitive |
| Typical cost | Priced per m²; varies with finish and cut-outs | Priced per m²; varies with colour and cut-outs |
If you love the reflective look but worry about upkeep, a grey or bronze mirror is a practical middle ground. You can see more colour and finish options on our glass splashbacks Sydney page.
Pros and Cons of a Mirror Splashback
A mirror splashback is a strong choice for small, dark or narrow kitchens, but it is not ideal for every household. Weigh the light and space benefits against the extra wiping and the fact that it reflects whatever sits on your bench.
Pros
- Brightens the room by reflecting natural and artificial light.
- Makes compact kitchens, galley kitchens and apartments feel more open.
- Smooth, grout-free surface that wipes clean.
- Toughened glass handles kitchen heat when installed correctly.
- Custom-cut to fit around power points, windows, and rangehoods.
Cons
- Fingerprints, water spots, and grease splatter are more visible on coloured glass.
- Reflects clutter, appliances and the underside of the rangehood.
- Edges and backing can deteriorate (“desilvering”) if moisture or harsh cleaners get in.
- It can create glare opposite a bright window or in a sunny outdoor kitchen.
- Cannot be cut or drilled on site once toughened, so measurements must be exact.
Can a Mirror Splashback Go Behind a Gas Cooktop?
Yes, a toughened mirror splashback can go behind a gas cooktop, but the distance to the nearest burner matters. Under the Australian gas installation standard, AS/NZS 5601.1, if a burner is within 200 mm of a wall, the splashback and the wall behind it must be protected with non-combustible materials. An ordinary, non-toughened mirror should never be used behind a cooktop.
Industry guidance on AS/NZS 5601.1 states that where the burner is closer than 200 mm, the glass must be toughened safety glass at least 5 mm thick, fixed over a non-combustible or fire-resistant backing, such as 10 mm plasterboard or 6 mm fibre-cement sheet. The same guidance notes a minimum clearance of 600 mm between the burner and the rangehood, and many rangehood manufacturers specify 650 mm. Always follow the cooktop and rangehood manufacturers’ installation instructions as well.
Gas fitting is licensed specialist work in NSW, so your gasfitter should confirm the final layout. Induction and electric cooktops don’t have the same open-flame clearance issues, but you should still follow the appliance manual.
How a Mirror Splashback is Measured and Installed
A mirror splashback is fitted last, after cabinetry, benchtops, power points and appliances are in. It is measured on-site, made to size off-site, and glued in place. Because toughened glass can’t be cut after manufacture, every cut-out is set to the measure.
- Finish the kitchen first. Cabinetry, benchtops, tapware, power points, and the rangehood should be installed so the measurements are final.
- Measure and template. The installer records the exact wall size and the position of every power point, switch and hole.
- Fabrication. The glass is cut, edges are finished, holes are made, and the glass is toughened before the mirror coating is applied.
- Wall preparation. The wall must be flat, sound and dry. Suitable substrates include plasterboard, Villaboard or fibre-cement sheet, rendered masonry and concrete. Behind a gas cooktop within 200 mm, a non-combustible backing is used.
- Installation. The panel is fixed with a mirror-safe adhesive, because some general-purpose adhesives can attack the mirror backing.
- Sealing. A mirror-compatible silicone is run around the perimeter to keep moisture away from the edges and backing.
In NSW, residential glazing work valued at more than 5,000 dollars in labour and materials (including GST) must be done by a licensed contractor. Before you book, ask any installer for their NSW contractor licence number and check it with NSW Fair Trading.
How to Clean a Mirror Splashback Without Damaging It
Clean a mirror splashback with warm water or an ammonia-free glass cleaner sprayed onto a soft microfibre cloth, not onto the glass. Wipe, then buff dry, paying attention to the edges. Avoid ammonia, vinegar, abrasive cream cleansers and scourers, which can damage the reflective backing or scratch the surface.
- For grease near the cooktop: first use warm water with a few drops of dishwashing liquid, then buff with a dry cloth.
- Keep the edges dry: moisture sitting on the sealed edge is the main cause of dark “black edge” spots over time.
- Never use steel wool, scrapers or rough sponges.
- Check the silicone seal once a year and have it replaced if it is cracked or lifting.

Frequently Asked Questions
Do mirror splashbacks scratch easily?
The glass surface is hard and resists everyday scratching from cloths and utensils. Scratches usually come from abrasive pads, grit trapped in a clot,h or sharp objects dragged across the panel. Use clean microfibre cloths and never use scourers. If a panel is badly scratched, a glazier can assess whether polishing or replacement is the better fix.
Can a mirror splashback be installed over existing tiles?
Often, yes, if the tiles are flat, firmly bonded and in good condition. The installer will check that the surface is level and that power points can be extended to suit the extra thickness. Uneven, cracked or drummy tiles should be removed first so the panel sits flat.
How thick is a mirror splashback?
Kitchen mirror splashbacks are commonly 6 mm toughened glass. Where a gas burner is closer than 200 mm to the wall, industry guidance in AS/NZS 5601.1 calls for toughened safety glass of at least 5 mm thickness over a non-combustible backing. Majestic Glass makes its splashbacks from 6 mm toughened glass.
How long does mirror splashback installation take?
Once the panel is made, installing a typical kitchen splashback usually takes a few hours. The full process takes longer because the measure happens after cabinetry is finished, and the glass is then fabricated and toughened. Ask for the expected lead time when you book the measure, as it varies by the chosen finish.
Will a mirror splashback fog up when I’m cooking?
It can fog briefly when a kettle or pot is steaming directly in front of it, just like a bathroom mirror. The fog clears quickly once the steam stops. Running your rangehood while cooking reduces both fogging and grease build-up on the glass.
Is a mirror splashback right for your kitchen?
A mirror splashback is a good fit if your kitchen is small, narrow, or short on light, and you are happy to wipe it more often than a coloured glass one. Choose toughened silver for maximum brightness; grey or bronze for a softer look with fewer visible marks; and antique only where heat isn’t an issue, unless it is toughened. Behind a gas cooktop, confirm the 200 mm clearance and backing requirements with your installer and gasfitter.
