Why Put a Window in Your Shower?

Adding a window to your shower provides both aesthetic and practical benefits. Letting in natural light creates an airy, open feel and a seamless connection between your shower and the surrounding space.

A Bright, Spacious Feel

A window fills your shower with natural light, giving the space an open, airy feel. The visual connection to the outside makes your shower feel more spacious and integrated with the rest of the room. The additional light also allows you to appreciate better the details of your shower, like tile work or hardware.

Improved Ventilation

A window in the shower also improves ventilation by allowing moist, humid air to escape. This can help prevent issues like mildew buildup. An open window provides passive ventilation, while an exhaust fan actively pulls humidity out of the space. Either option helps keep your shower fresher and prevent damage to walls and fixtures from excess moisture.

Easy to Maintain

Contrary to what some may think, a window in the shower is not difficult to maintain. Using a squeegee to wipe down the glass after each use will prevent hard water spots and soap scum buildup. For more stubborn stains, a commercial glass cleaner or a mixture of vinegar and water works well. With regular cleaning and attention, a shower window can provide years of stunning views.

Adding a window to your shower comes with many benefits and with proper care and maintenance is simple to incorporate into your space. Let the natural light in and enjoy a brighter, fresher shower experience. A shower window may be just the touch your bathroom needs.

Choosing the Right Type of Window for Your Shower

Choosing a window for your shower requires careful consideration of several factors. The most important is selecting a window that is specifically designed and rated for use in wet areas like bathrooms. Regular windows will not withstand the high humidity levels and condensation that occur in showers.

Frame and Sash Material 

For shower windows, vinyl, aluminum, fiberglass, and composite frames are good options as they resist moisture and rot. Wood frames, while attractive, require diligent maintenance and sealing to prevent water damage. The sash, or movable part of the window, should also be made of a water-resistant material. Vinyl sashes are a popular, low-maintenance choice.

Safety and Privacy

In a shower, safety and privacy are also concerns. Tempered or laminated glass should be used as it is less likely to shatter on impact. Obscured or textured glass can allow light in while maintaining privacy. For clear views, consider windows situated high on the wall or with transoms that can be opened for ventilation.

Ventilation and Energy Efficiency

Proper ventilation is important for controlling moisture and preventing mold growth in the shower. Choose a window that can be opened to allow for air flow. Double or triple-paned windows with low-emissivity coatings also improve energy efficiency by preventing heat transfer.

With the right type of window designed specifically for high-moisture areas and by considering factors like material, safety, privacy, and efficiency, you can enjoy the benefits of natural light in your shower while avoiding damage or other issues. Keeping these points in mind will help ensure you make an informed choice in selecting the perfect shower window for your needs.

Window Placement and Design Options for Your Bathroom

When choosing a window for your shower, the location and design are important factors to consider for both aesthetics and functionality. Carefully selecting an appropriate window and placement can allow natural light to brighten your space while maintaining privacy.


The optimal location for a shower window is on a wall adjacent to the shower head, rather than directly in front of it. A window on the side wall allows natural light to filter in while avoiding direct exposure. If possible, choose a wall that faces away from public areas outside. For minimal visibility, a frosted, textured, or stained glass window is ideal.


A smaller window, around 2 to 3 feet in either height or width, provides adequate natural light for a standard shower while maximizing privacy. However, if facing a private outdoor space, a larger window, around 4 to 5 feet, can make a shower feel more open and airy. Consider matching the window size to your shower’s scale and available wall space.


For high humidity areas like showers, vinyl, aluminum, or vinyl-clad wood frames are suitable since they resist damage from moisture. Avoid bare wood or steel frames which can warp, rot, or corrode over time. A sloped sill at the base of the frame directs water away from the opening. For easy cleaning, choose a frame that attaches inside the shower wall.

Obscured Glass

For privacy with natural light, obscured glass like frosted, etched, or textured glass diffuses shapes and images on the other side. Stained or colored glass in amber, green or blue hues gives the light a warmer glow. For a decorative touch, beveled, leaded or patterned glass filters light in an intricate design.

With the proper placement, size, frame, and glass type for your needs, a shower window can be both stylish and functional. Paying attention to these details will allow you to enjoy natural illumination and an open feel in your shower while maintaining complete privacy.

Caring for Your Shower Window to Prevent Damage

To prolong the lifespan of your shower window and prevent costly damage, it is important to perform regular maintenance. As with any fixture exposed to high humidity and temperature fluctuations, shower windows require frequent inspection and cleaning to remove built-up grime and soap scum, as well as periodic resealing to protect from water damage.

Regular Cleaning

After each use, wipe down your shower window with a microfiber cloth to remove excess water and debris. For stuck-on residue, use a commercial glass cleaner or a solution of equal parts white vinegar and water. Avoid using abrasive cleaners, as these can scratch the glass surface. For hard water stains, make a paste from baking soda and water and gently scrub with the paste using a soft sponge or non-abrasive scrubber. Rinse well with water to remove all paste residue.

Resealing and Waterproofing

Over time, the sealant around the edges of the shower window can break down, allowing water to seep in. Inspect the sealant regularly for cracks or peeling and reseal as needed. For the best protection, reseal your shower window with a high-quality silicone or polyurethane sealant once every six to twelve months. Follow the directions carefully, ensuring you clean and dry the area before applying the new sealant.

Preventing Fog and Condensation

To prevent excess condensation on your shower window, run an exhaust fan while showering and for at least 20 minutes afterward. You can also slightly crack a window or vent to improve airflow. Wiping down your shower window with a towel after each use will also help prevent water spots and soap scum buildup, as well as keep your glass clear.

By establishing a regular maintenance routine, your shower window can remain crystal clear and leak-free for many years. Be sure to inspect for any signs of damage or water intrusion in between scheduled cleanings or resealing and address issues immediately to avoid costly repairs down the line. With some simple preventative measures, you can keep your shower window looking as good as new.


So now you know all the key steps for properly caring for and maintaining your shower window to keep it looking beautiful and performing at its best. Regular cleaning and sealing are vital. Choose high-quality products and tools to avoid streaks and scratches. Inspect for leaks, cracks, and fogging issues right away and repair promptly to prevent water damage and mold growth. With the right maintenance routine, your shower window can stay clear and flawless for years of enjoyable bathing. Implement these tips, and you’ll keep your shower window in top shape for safety, style, and clarity.
