What to Ask Before Ordering a Custom Cut Mirror Online
Ordering a custom cut mirror online is one of the easiest ways to upgrade a bathroom, bedroom, gym, or feature wall. But many people only realise what they should have asked after the mirror arrives — when it doesn’t fit properly, the edges aren’t finished as expected, or installation becomes more complicated than planned.
This guide covers the essential questions you should ask before ordering a made-to-measure mirror online, helping you avoid costly mistakes and ensuring your mirror looks great and lasts for years.
1. Is the mirror truly cut to size?
Not all “custom” mirrors are fully bespoke. Some sellers offer standard sizes with slight adjustments rather than true made-to-measure cutting.
Ask before ordering:
- Are mirrors cut exactly to my measurements (to the millimetre)?
- Is there a size tolerance I should be aware of?
- Do I need to allow clearance for tiles, walls, or fittings?
Why this matters:
Even a few millimetres can make the difference between a seamless fit and visible gaps — especially in alcoves, wardrobes, or wall-to-wall mirror installations.
2. What mirror thickness should I choose?
Mirror thickness affects stability, weight, reflection quality, and long-term durability.
Common thickness options:
- 4mm – Suitable for small mirrors or framed use
- 6mm – Ideal for most bathrooms and wall mirrors
- 8mm – Best for large mirrors, gyms, and feature walls
Ask:
- What thickness do you recommend for my mirror size?
- Will a thinner mirror flex or distort?
- Does thickness affect mounting or adhesive choice?
Why this matters:
Larger mirrors benefit from thicker glass, which stays flatter and feels more premium once installed.
3. Are the edges polished or unfinished?
Mirror edges are often overlooked — but they affect both safety and appearance.
Ask:
- Are the edges polished, seamed, or raw?
- Are polished edges included in the price?
- Are the edges safe for exposed installations?
Why this matters:
If the mirror edges will be visible (frameless mirrors, feature walls, gyms), polished edges are essential for a clean, professional finish and safe handling.
4. Is safety backing included?
Safety backing is a protective film applied to the back of the mirror to reduce injury risk if it breaks.
Ask:
- Does the mirror include safety backing?
- Is it recommended for my installation type?
- Is safety backing required for gyms or commercial spaces?
Why this matters:
In the event of breakage, safety backing helps keep glass fragments together — particularly important in bathrooms, gyms, and family homes.
5. Can the mirror be cut around sockets or fixtures?
Many walls include obstacles that need precise cut-outs.
Ask:
- Can you cut holes for sockets, switches, or taps?
- Do you offer corner radius or notched cut-outs?
- What measurements or diagrams do you need?
Why this matters:
Trying to modify a mirror after delivery is risky and often impossible. All cut-outs must be planned before manufacturing.
6. Is the mirror suitable for bathrooms and humid areas?
Bathrooms expose mirrors to moisture, steam, and temperature changes.
Ask:
- Is the mirror suitable for bathroom use?
- How are the edges protected against moisture?
- Will humidity affect the backing over time?
Why this matters:
Poor edge protection can lead to black spots or mirror corrosion, especially in poorly ventilated bathrooms.
7. How should the mirror be installed?
Installation requirements vary depending on mirror size and weight.
Ask:
- Should the mirror be installed with adhesive, clips, or channels?
- Is professional installation recommended?
- Do you provide installation guidance?
Why this matters:
Incorrect installation can cause stress points, distortion, or even mirror failure over time.
8. How will the mirror be packaged and delivered?
Mirrors are fragile and require careful handling during transport.
Ask:
- How is the mirror packaged?
- Is delivery insured?
- What should I do if the mirror arrives damaged?
Why this matters:
Proper packaging and clear delivery procedures reduce the risk of breakage and make replacements easier if something goes wrong.
9. What is the expected lead time?
Custom mirrors are made to order and cannot be shipped immediately.
Ask:
- How long does manufacturing take?
- Does delivery time vary by size or finish?
- Will I be notified when the mirror ships?
Why this matters:
If your mirror is part of a renovation or tight schedule, lead time can affect your entire project timeline.
10. What is the return or replacement policy?
Custom mirrors are often non-returnable unless faulty.
Ask:
- What happens if the mirror arrives damaged?
- What if measurements are incorrect?
- Do you offer replacements or refunds?
Why this matters:
Understanding the policy protects you in case of manufacturing defects or transport damage.
11. How do I clean and maintain the mirror?
Improper cleaning can shorten a mirror’s lifespan.
Ask:
- What cleaning products should I use?
- Are there products I should avoid?
- How do I prevent edge damage over time?
Why this matters:
Using the wrong cleaners or soaking the edges can cause long-term damage, especially in bathrooms.
