One of the most obvious signs that it's time to replace your bathroom mirror is visible damage. Cracks, chips, and broken corners not only affect the appearance of your space but can also be dangerous. Broken edges can pose a safety hazard, especially in a family home with children.

In addition to cracks, keep an eye out for signs of desilvering- when the reflective coating on the back of the mirror begins to wear away. This often appears as black spots or streaks along the edges of the glass. Once desilvering starts, it usually gets worse over time and can't be repaired easily, signaling that it's time for a replacement.

Bathrooms are humid environments, and over time, excessive moisture can take a toll on your mirror. If your mirror constantly fogs up and takes a long time to clear, even with an exhaust fan, it may be due to poor ventilation or the mirror's inability to handle humidity. Worse still, moisture can seep into the backing of the mirror and cause damage from within. Upgrading to a mirror designed for high-moisture areas or one with anti-fog features can make a world of difference in your daily routine.
