FAQ
What type of glass do these mirrors come in?
These 400 x 600mm mirrors are generally available in standard float glass, often with a silvering backing for optimal reflectivity. Some premium options might include tempered or even toughened glass for added safety – verify the product description.
Do these mirrors come with integrated LED lighting?
Many listings feature integrated LED strips along the edges of the mirror, providing ambient lighting. However, not all 400 x 600mm models include this; carefully review the specifications to confirm if lighting is present.
Are demister pads included with these mirrors?
Demister pads are a common feature for preventing condensation on bathroom mirrors. Check the product details to see if a demister pad is included, or if one needs to be purchased separately – consider purchasing one regardless.
What wall fixings do I need?
Most 400 x 600mm mirrors come with basic screw fixings suitable for plasterboard walls. However, for heavier mirrors or brick/stone walls, you may require specialist wall plugs and screws – consult a hardware professional.
How thick is the glass in these mirrors?
Typically, 400 x 600mm bathroom mirrors have a glass thickness of around 6mm to 8mm. This provides sufficient strength for most installations, but always check the specific product details for precise measurements.
Can I drill through these mirrors for fixing?
While some models are designed to be drilled, it’s generally recommended to have this done by a professional installer to avoid cracking the glass. If drilling is required, use appropriate safety precautions and suitable drill bits.
What's the best way to clean these mirrors?
Use a microfiber cloth with a mild cleaning solution specifically designed for glass. Avoid abrasive cleaners that could scratch the surface of the mirror – dry immediately after wiping.
How do I measure my wall space accurately?
Measure the width and height of the area where you intend to hang the 400 x 600mm mirror, taking into account any obstacles such as pipes or radiators. Add extra inches for fixing holes and allow for a small gap at the edges.
Are these mirrors suitable for use with heated towel rails?
While generally suitable, prolonged exposure to heat from a heated towel rail can potentially cause condensation on the mirror’s surface. Ensure adequate ventilation in your bathroom to mitigate this risk.
What guarantees are available for these mirrors?
The manufacturer's warranty will typically cover defects in materials and workmanship for a specified period (usually 1-2 years). Please refer to the individual product listing for details on Amazon’s standard returns policy.
