When installing your mirror, first of all, choose your spot and ensure you’re not in any danger of drilling into any electrical cables in your bathroom wall. Consider things like direction of natural light (unless you have an illuminated mirror) and ease of daily use when you’re deciding where to position your mirror. Ensure you’re happy with the placement of the mirror.
First by holding it up yourself and getting up close, as you will when using it; then asking someone else to hold it in the same position, while you look at it from further away, to gauge how it appears to the rest of your bathroom. Use a spirit level to ensure the mirror is straight, and mark the position of its four corners lightly on the wall to use as a guide while you drill your fixing holes.
To create these fixing holes, first measure very carefully, then double check your measurements – then drill. Take care if you’re drilling through tile not to crack the tile: using a hard drill bit and applying gentle pressure for a sustained period while drilling will give you a higher chance of drilling your holes without mishap than using brute force.
If your wall consists of brick or blockwork beneath its plaster, you’ll need to insert wall plugs into your wall holes to screw into; if it’s a timber stud wall you won’t. Ensure you drill into the hardest part of the wall to increase your mirror’s staying power: drilling into the mortar between bricks, or into the plasterboard between timber studs, will not give a satisfactory hold for your screw fixing.
Depending on the power source for the lighting in an illuminated mirror, you may need to wire the mirror up. Alternatively, it may be powered by an internal battery and not require any electrical work during installation. Bear in mind that all home electrical work should always be carried out by a qualified electrician, so please make sure you hire a professional for installation if you do buy mains powered illuminated mirror.
