When you start shopping for mirrors, the sheer range of prices can feel overwhelming. A quick search turns up everything from £30 flat-pack options to bespoke pieces quoted in the thousands — and it’s not always clear what you’re actually paying for. Whether you’re renovating a bathroom, styling a living room feature wall, or commissioning a full-length dressing mirror, understanding the real drivers behind custom mirror cost helps you budget confidently and avoid nasty surprises.
At Berwyn Glass, we believe pricing should be transparent. This guide breaks down exactly what affects your quote, room by room, so you can walk into any project knowing what to expect.
What Factors Affect Custom Mirror Cost?
Before diving into room-specific numbers, it helps to understand the variables that shape any bespoke mirror cost. No two mirrors are priced identically, and that’s by design — a custom piece is built around your exact space and requirements.
-
Size and Glass Area
This is the single biggest cost driver. Glass is priced per square metre, so a large wall mirror cost will always be higher than a compact vanity piece, even if every other variable is the same. A bathroom mirror measuring 500mm × 700mm uses roughly a third of the glass of a 1,200mm × 900mm bedroom option.
-
Glass Type and Specification
Standard clear float glass sits at the affordable end. Step up to low-iron glass (noticeably clearer, with no green tint), tinted glass, or anti-fog glass for bathrooms, and the custom mirror price rises accordingly. Safety-backed glass — laminated or toughened — adds further cost but is legally required in certain locations, including shower enclosures.
-
Edge Finish
A raw cut edge is the starting point. Polished edges, bevelled edges, and pencil-ground edges each require additional machine time, which adds to the overall mirror glass quote. A bevel in particular — where the edge is ground at an angle to create a prism effect — is a signature of traditional framed mirrors and commands a small premium.
-
Frame vs. Frameless
Frameless mirror price points are generally lower in terms of materials, but precision cutting and polishing are essential to make the glass itself look finished. A framed mirror introduces the cost of the frame — timber, metal, resin, or reclaimed materials — which can range from modest to significant depending on the craftsperson involved.
-
Shape
Rectangles and squares are the cheapest to cut. Circles and ovals require specialist cutting and edge polishing. Irregular or bespoke arched shapes, popular in hallways and alcoves, involve the most time and therefore the highest cutting costs.
-
Fixings and Mirror Installation Cost
Getting a mirror safely and squarely onto your wall is not always straightforward, particularly for large or frameless pieces. Mirror installation cost typically covers site visit, drilling, appropriate fixings (mirror screws, standoffs, adhesive clips, or a full hanging system), and disposal of any packaging. For heavy pieces — anything over 15 kg — two fitters are standard practice.
-
Extras: Demister Pads, Lighting, Smart Features
Integrated LED lighting, demister pads that prevent condensation, and touch-sensor controls all add functionality but also add to the final invoice. These are almost always worthwhile in bathrooms, where steam is a constant enemy of mirror clarity.
Custom Mirror Cost by Room
Bathroom Mirror Price
The bathroom is where most people begin their custom mirror journey, and it’s easy to see why — a well-specified mirror transforms a utilitarian space into something that feels genuinely designed.
Entry-level bathroom mirror price (simple rectangle, clear float glass, polished edges, no extras): £80–£150 for supply only, depending on size.
Mid-range (low-iron glass, demister pad, basic LED backlight, fixings included): £200–£450.
Premium bespoke (full-width mirror spanning an entire alcove or double-vanity, anti-fog glass, integrated warm/cool LED strip, touch sensor, professional installation): £600–£1,200+.
The bathroom is also where safety glass requirements most often apply. If your mirror sits above a bath or inside a wet area, toughened or laminated glass is not optional — factor that into your custom mirror cost from the start.
At Berwyn Glass, every bathroom quote includes a recommendation on glass specification based on the position and proximity to water. We’d rather have the conversation upfront than see a client compromise on safety to save a small amount.
Living Room and Feature Wall Mirror
Large wall mirrors in living spaces serve a dual purpose: they bounce light and create a sense of depth that makes rooms feel larger. The trend for oversized, frameless or slim-framed statement mirrors shows no sign of slowing down.
Large wall mirror cost varies enormously based on dimensions. As a guide:
- 600mm × 900mm frameless mirror price, polished edges, hanging system included: £120–£220
- 1,000mm × 1,500mm frameless mirror, low-iron glass, standoff fixings, professional installation: £380–£650
- Full-height alcove mirror, floor to ceiling in a Victorian terrace (typically 1,200mm × 2,400mm), bespoke-cut, toughened: £800–£1,500 fitted
The bespoke mirror cost for living spaces tends to increase significantly when you move into shaped mirrors. A circular mirror with a diameter of 800mm, polished edges and a surface-mounted chrome fixing: expect £180–£320 supply only from a specialist like Berwyn Glass. Arched mirrors — currently very popular for hallways and statement walls — start around £250 for modest sizes and climb quickly with scale.
Bedroom and Dressing Room
Full-length mirrors are a bedroom staple. Whether free-standing or wall-mounted, the specification and sizing choices have a direct impact on price.
A standard full-length custom mirror (1,800mm × 600mm, float glass, polished four sides, mirror screws): £110–£190 supply only.
Upgrade to a floor-to-ceiling wardrobe mirror panel (sliding door application, safety-backed glass, 2,200mm × 800mm per panel): £200–£380 per panel, with mirror installation cost on top depending on the sliding door system.
Dressing rooms with multiple mirrored panels or angled corner mirrors introduce complexity in measuring and templating. Berwyn Glass offers on-site measuring for jobs like these, which eliminates the risk of ordering glass that doesn’t fit — always worth the small additional fee.
Hallway and Entrance
Hallway mirrors are often the first thing guests see and the last thing you check before leaving. A good specification here creates a strong first impression.
Small to medium hallway mirror (arched top, 600mm × 1,000mm, float glass, polished edges): £130–£240.
Large hallway statement mirror (1,200mm × 1,800mm, toughened safety glass, bespoke arch or rounded top, professional installation): £500–£900 fitted.
Antique-effect and bronzed mirrors — popular in period properties — sit at the higher end of the custom mirror price range due to the specialist silvering process. A 900mm × 1,200mm antique mirror panel: £280–£450 supply only.
Commercial and Hospitality Projects
Hotels, restaurants, retail spaces, and gyms frequently commission large runs of custom mirrors. At Berwyn Glass, commercial projects are quoted individually, but as a general steer:
- Gym mirror wall (full-height panels, toughened, 10–15 linear metres): £3,500–£7,000 fitted, depending on access and wall condition.
- Hotel bathroom mirrors (bespoke size, LED backlit, demister, frameless, per room): £350–£800 per unit on volume orders.
- Retail display mirrors (custom shapes, bevelled edges, wall-mounted): £200–£600 per piece.
Volume pricing applies on larger orders — always worth asking for a trade or project rate.
Understanding Your Mirror Glass Quote
When you receive a mirror glass quote, it should itemise clearly. At Berwyn Glass, every quote breaks out:
- Glass specification and dimensions
- Edge finish
- Any coatings (anti-fog, tinting, safety backing)
- Frame or fixing system
- Delivery or site-visit cost
- Mirror installation cost (if applicable)
- VAT
Watch out for quotes that bundle everything into a single line — you can’t compare suppliers fairly without knowing what’s included. A quote that appears lower may be omitting installation, or substituting float glass where low-iron was specified.
Supply Only vs. Supply and Fit: What’s the Real Difference?
Many customers choose to source glass from a specialist like Berwyn Glass and arrange their own installation. This works well for simpler pieces — a bathroom mirror up to around 1,000mm × 700mm can be hung by a competent DIYer with the right fixings.
For anything larger, heavier, or more complex, supply-and-fit is usually the smarter choice. Mirror installation cost with a professional team typically adds £60–£200 to a domestic job, depending on access, height, and whether any wall preparation is needed. On a £500 mirror, that’s a modest premium for peace of mind — and a guarantee that the mirror is level, securely fixed, and protected during the process.
For commercial projects, professional installation is almost always specified by default, and rightfully so. The liability implications of a poorly installed large mirror are not worth the saving.
How to Get an Accurate Custom Mirror Cost
The most reliable way to get a realistic figure is to provide as much detail as possible upfront. At Berwyn Glass, we ask for:
- Exact dimensions (or a site visit for complex jobs)
- Preferred glass type (standard float, low-iron, tinted, safety)
- Edge finish
- Frame requirement (frameless, existing frame to reglaze, or new frame)
- Location (bathroom, wet area, commercial space — safety spec may apply)
- Any extras (LED, demister, standoff fixings)
- Timeline
With that information, we can turn around an accurate mirror glass quote quickly — usually within one working day for standard requests.
