Mirror and Glass FAQs
These Mirror and Glass FAQs answer some of the most common questions we receive about choosing, measuring and installing mirrors and glass. If you are planning a project and need clear, practical guidance, this page should help you decide what is right for your space.
Mirror FAQ
What thickness of mirror should I choose?
For most wall mounted mirrors, we recommend 6mm thickness because it offers strength and a high quality reflection. For furniture doors, wardrobe doors and some internal panels 4mm mirror is often used to keep weight down.
Can I use a mirror in a bathroom?
Yes. Choose a foil backed or safety backed mirror and make sure it is installed on a dry, sound wall. Mirror adhesive is usually the cleanest way to fix bathroom mirrors.
Can you make custom shapes?
Yes. We can supply round, oval, arched and angled mirrors as well as simple rectangles and squares, all cut to your measurements.
How accurate do my measurements need to be?
Please measure in centimetres or millimetres as accurately as possible. All mirrors are cut to order and cannot be trimmed once manufactured. You may also find our Mirror Measuring Guide helpful before ordering.
How will my mirror be delivered?
All mirrors are carefully packaged to protect them in transit and delivered securely to the kerbside at your address. Delivery is typically within 7 to 10 working days across the UK mainland. For full details on delivery times, access requirements and what to expect on the day, please see our Delivery Information page.
Do you install mirrors?
We install mirrors within the M25 and we recommend this option for larger mirrors or more complex projects. Contact us with your measurements and location for more information. You can read more in our Mirror Installation Guide.
Glass FAQ
What thickness of glass do I need for shelves?
For example, short shelves carrying light items can use 8mm glass, longer shelves or those carrying heavier loads should use 10mm or 12mm glass.
Do splashbacks need to be toughened?
Not necessarily. Glass used behind hobs and in kitchen working areas should be toughened for safety and heat resistance, but regular glass will be fine for the rest of the kitchen. The exception is if you need cut outs for sockets, then toughened glass is necessary.
Can you cut around sockets and switches?
Yes. We can cut precise shapes and holes for sockets, switches, extractor controls and other fittings as long as accurate measurements or templates are provided.
Do you offer a templating service?
Yes. For projects that MirrorFit installs within London and the M25, such as splashbacks, shower glass and balustrades, a templating service is available to ensure a perfect fit.

Installation FAQ
Is mirror adhesive strong enough for a heavy mirror?
Yes. When used correctly on a suitable surface, mirror adhesive is extremely strong. For this reason, support heavy mirrors for at least 24 hours while the adhesive cures.
Can I install a mirror myself?
Many customers install their own mirrors by following our How to Install a Mirror at Home step by step guide. For very large mirrors we recommend having two people to help lift the mirror and for complex layouts it may be safer to use a professional installer.
For general guidance on safe lifting, you may find the Health and Safety Executive’s manual handling advice useful.
What if my wall is not perfectly flat?
Small variations can be taken up by adhesive. If the wall is very uneven, it may need to be skimmed or levelled before installation to achieve the best result.
