A Guide to Keeping Custom Bathroom Mirrors Clear During Toronto Winters

January 4th, 2024

Winter brings with it unique challenges, and one of the most frustrating is dealing with foggy bathroom mirrors. Whether you are rushing to get ready for work or winding down after a long day, a fogged-up mirror is certainly an inconvenience.

In this post, we explore the reasons it occurs in winter and practical solutions to ensure your bathroom mirrors stay crystal clear even in the coldest months.

Let’s get started.

How to Stop Custom Bathroom Mirrors from Defogging During Toronto Winters

Here, we explore the key causes of fogging bathroom mirrors in your Toronto home during winter. We will also discuss the solutions to prevent this and the types of mirrors that are suitable for this cold season.

Common Causes of Bathroom Mirror Fogging During Toronto Winters

Below are the main reasons why bathroom mirrors fog up.

Temperature Differential

When warm, moisture-filled air comes into contact with a cold surface, condensation occurs, leading to the creation of small water droplets on the surface. This is why bathroom mirrors tend to fog up during winter – the temperature contrast between the warm air in the bathroom and the cold mirror surface triggers condensation.

Inadequate Ventilation

Poor ventilation can trap humid air in the bathroom, increasing the likelihood of your custom mirror fogging. During winter, people tend to keep windows closed, reducing natural ventilation.

Hot Showers

Steam generated during hot showers contributes to mirror fogging. Cold winter air can make it more challenging for steam to dissipate quickly.

Best Solutions to Prevent Bathroom Mirror Fogging Up in Winter

Bathroom Mirror Fogging Up

Let’s check out practical solutions you may use to stop custom bathroom mirrors from fogging up during this coldest season.

Use Anti-Fog Sprays and Films

Anti-fog sprays and films are designed to create a protective layer on the mirror’s surface, preventing condensation. Anti-fog sprays contain substances such as polymers, alcohol, or ethanol that reduce surface tension, preventing water droplets from forming. Similarly, anti-fog films adhere to the mirror and provide a barrier against condensation. These solutions are cost-effective and readily available at most home improvement stores.

Adjusting Indoor Humidity

Consider using a dehumidifier to remove excess moisture from the air. This is especially important during winter when indoor heating systems can contribute to elevated humidity levels.

Ventilation Strategies

Improving ventilation in the bathroom is an effective way to combat mirror fogging. Ensure your bathroom is equipped with an exhaust fan and use it consistently, particularly during and after hot showers. The fan helps expel humid air, preventing it from settling on the mirror.

Consider installing a louvred door or leaving the bathroom door slightly ajar to facilitate air circulation. This simple adjustment can improve the overall airflow in the bathroom, minimizing the conditions conducive to mirror fogging.

Heated Mirrors

For a more permanent solution, consider installing a heated mirror. These mirrors feature built-in heating elements that maintain a consistent surface temperature, preventing condensation. Some models come with demisting features that automatically activate when needed, ensuring a clear reflection even on winter days.

Heated mirrors are available in various sizes and styles, making them a versatile and aesthetically pleasing option. While they may require a slightly higher upfront investment, the long-term benefits in terms of convenience and clarity make them a worthwhile addition to your bathroom.

DIY Solutions

If you prefer a more hands-on approach, several do-it-yourself solutions can help prevent mirror fogging:

  • ●Mix equal parts white vinegar and water, then apply the solution to the mirror. Wipe it off with a clean cloth to create a fog-resistant surface.
  • ●Spread a small amount of high-quality dish soap or shaving cream evenly on the mirror. Wipe away the excess to create a thin, anti-fogging layer.

While the effects may not be as long-lasting as commercial solutions, they can be a quick and convenient fix for temporary relief from mirror fogging.

Innovative Approaches to Mirror Defogging

Let’s discuss modern approaches you may adopt to defog bathroom mirrors.

Smart Mirrors

Embrace the future with smart mirrors equipped with anti-fogging technology. These often feature built-in sensors that detect changes in humidity and temperature, activating anti-fog measures as needed.

Some smart mirrors come with integrated heating elements, ensuring a consistently clear surface. Additionally, installing these mirrors may offer additional features such as adjustable lighting, Bluetooth connectivity, and voice-activated controls to enhance your overall bathroom experience.

Mirror Defogging Devices

Invest in dedicated mirror-defogging devices that can be installed behind the mirror. These often use low-energy heating elements such as thin films, conductive coatings, or resistance wires to maintain the mirror surface temperature, preventing condensation.

Mirror-defogging devices are discreet and can be easily integrated into existing bathroom setups. They provide a reliable, hands-free solution for keeping your mirror clear, especially in winter when temperature differentials are more pronounced.


Banishing winter mirror fog requires a multifaceted approach encompassing an understanding of practical solutions and innovative technologies. Adjusting humidity levels, improving ventilation, and using anti-fogging products are all effective strategies for maintaining a clear reflection. Whether opting for a simple DIY remedy or investing in cutting-edge technology, the key is to find a solution aligned with your preferences and lifestyle. By doing so, you can bid farewell to foggy mirrors and ensure a clear view, enhancing your comfort and convenience throughout the winter months. To learn more, contact Academy Glass.
