Let’s face it—no modern bathroom design feels complete without a proper wall mirror. But the question remains: how do you securely fix a mirror to bathroom tiles? With a vast array of shapes and styles to choose from, including frameless, magnifying, illuminated, swiveling, and integrated media (e.g., audio) models, making the final selection can be tricky. However, that challenge is minor compared to the daunting task of actually mounting the mirror!
Fret not; our experts have compiled these straightforward guidelines to help you approach the task with confidence.
There is no single “one-size-fits-all” method for fixing a mirror to tiles. The appropriate technique depends heavily on the mirror’s size and weight, as well as the composition and condition of your walls.
A Note on Powered Fixtures
High-tech, multi-function mirrors that feature illumination or demisting elements require connection to an earth wire. If you choose this type of model, you must enlist the services of a qualified electrician to ensure proper and safe installation. For obvious reasons, simple, lightweight, non-anchored mirrors are the best choice for a DIY installation.
Preparation is Key
As in many aspects of life, meticulous preparation is crucial for success.
- Clean the Surface: Before starting, ensure your tiled wall surface is spotlessly clean. Use a soft cloth and an appropriate cleaning fluid to remove all traces of dirt, dust, and grime.
- Apply Adhesion Strips: Smooth strips of double-sided adhesive tape onto the back of the mirror, running parallel to its edges.
- Apply Sealant: For maximum strength, apply a continuous bead of silicone adhesive alongside the perimeter defined by the double-sided tape. The amount of adhesive tape and silicone needed should be proportionate to the size and weight of the mirror. When in doubt, do not skimp on the adhesive!
Finding the Perfect Position
Determining the exact placement of your mirror is another vital preparatory step.
- Choose the Location: Select your desired wall location.
- Mark the Guide Lines: Use a pencil and a spirit level to accurately mark the intended outer and bottom edges of your mirror on the wall. A good rule of thumb is to position the mirror so that its top edge sits squarely in the middle of a tile or at an aesthetically pleasing height relative to the surrounding tile pattern.
The Sticking Point
When fixing the mirror to the tiles, a little physical support goes a long way.
- Create Support: Stack sturdy boxes or packing blocks until their height is level with the bottom edge you marked on the wall. For extra security, you can temporarily affix these blocks to the wall using masking tape.
- Prepare the Mirror: Carefully remove the protective backing from the double-sided tape on the mirror’s reverse side. (We highly recommend enlisting a helper for this step, as an extra pair of hands is invaluable when handling large, sticky objects!)
- Safety First: In the event of an accidental drop, protect yourself by putting on safety glasses and gloves.
- Placement: Gently rest the bottom edge of the mirror onto your support blocks and carefully position it against the marked area on the wall.
- Secure the Bond: Apply gentle, steady pressure to the glass, starting in the center and working outward towards the edges. This action helps to spread the silicone adhesive more evenly, significantly improving the strength of the bond.
- Final Brace: For added security, apply strong adhesive tape (like duct or masking tape) across the mirror’s corners and edges, securing it to the wall temporarily.
- Wait: To successfully bond the mirror to the tiles, the silicone adhesive needs at least 24 hours to set completely. Resist the temptation to touch or remove the supports before this curing time has fully elapsed!
