A window in the shower can brighten the space, make your shower feel larger, and provide more ventilation to prevent mold and mildew. However, installing a window in a private area comes with some challenges, such as determining the best window type and window covering solution.
We’ll review different window options for your bathroom shower, suggest methods to increase privacy while maximizing natural light, and provide a few window replacement tips.
Types of Windows for Your Shower
This window has a hinge on its top and opens outward from the bottom, providing ventilation and increasing natural light. Although an awning window can improve airflow in your shower, it can be challenging to clean due to its slant.
A casement window, also called a crank window, has hinges on its side and opens outward to the left or right. Though it’s energy efficient, this window can break easily when its hardware ages and rusts.
This type of window is composed of multiple blocks of thick glass within a window frame. It increases your shower’s privacy but doesn’t let a lot of light in or allow for any ventilation.
A hopper window is basically an upside down casement window. It has hinges at the bottom and opens inward from the top. This window is great for ventilation and letting in fresh air, but it can catch debris when it’s open and takes up more space than other window types.
A picture window doesn’t open or close. It’s made of a single pane of glass that gives you an unobstructed view of the outdoors, and it doesn’t provide any ventilation.
A skylight is a window installed on the roof and is typically made of transparent or translucent glass. It provides more light than other windows, but it’s hard to clean and can lead to heat loss or gain when not installed in the right location.
A slider window looks like a double-hung window, but it opens horizontally. Sliding windows provide plenty of ventilation, but their sliding track is prone to dirt buildup, which can make them difficult to open and close.
A transom window is a small window that typically sits above a large window or door. You can also install one in your shower. Transom windows can make your shower space brighter and provide more privacy, but they’re harder to clean and maintain.
Ideas for Maximizing Privacy in Your Shower
Privacy is vital if you want to install a window in the shower. Window treatments, such as blinds, shades, shutters, and drapery, can help block your window temporarily, while decorative films or textured glass can cover the window and allow natural light and privacy at all times. Below, we’ve outlined a few solutions to cover your shower window and maximize privacy.
Window Treatments for Privacy
A window treatment is a decorative covering that controls the light entering a room while providing some privacy. Different window treatments, such as blinds, shades, and shutters, can help block outside views into your shower space.
- Blinds: Blinds are window coverings composed of slats that you can control to change the light and visibility in your shower. Blinds come in various styles, materials, and colors and can be removed for easy maintenance. Choose a waterproof material, such as faux wood or polyvinyl chloride (PVC), to prevent water damage.
- Shades: Roman shades, which are pulled down or lowered, are an energy-efficient option that control the light and visibility in your bathroom. Consider waterproof Roman shades or shades made of mildew-resistant fabric to avoid moisture damage.
- Shutters: Shutters provide an even greater sense of control over the light and visibility in your space and come in a range of waterproof styles and finishes. Avoid bamboo, wood, or fabric-based options, as the steam from your showerhead can warp the material and allow mold and mildew to fester.
Decorative Glass Films
Decorative glass films are made of a durable material and typically feature a design. They can mimic different types of glass, such as frosted glass or etched glass, while maintaining privacy and letting light into your shower area. Check your window warranty before applying a decorative glass film, as some window manufacturers will void your warranty if you apply a film.
Here’s how to install a decorative glass film in your shower:
- Before applying the film, clean the glass window with a solution composed of 1 teaspoon of baby shampoo mixed with 1 gallon of filtered water.
- Measure your window and note its height and width.
- Cut the window film to size with a utility knife and remove the film backing.
- Starting at the top of the window, apply the window film to the edges and corners, keeping the film level with the window. Work the film down the window and overlap the film with the window frame.
- Trim any excess film with a utility knife or box cutter.
- Push any large air bubbles to the edge of the film with your hand. Use a hand squeegee to push any remaining air bubbles to the edge of the film.
Patterned or Textured Glass
Patterned or textured privacy glass is a more permanent solution compared to decorative glass films. A highly textured surface or patterned glass can improve your bathroom’s privacy while allowing natural light into the space. Common types of textured glass include frosted glass, patterned glass, rain glass, etched glass, and stained glass.
How Much Does a Shower Window Cost?
New window installation is a considerable investment. Homeowners spend anywhere from $1,000 to $5,000* or more to install a new window in the shower.
Your privacy solution is another cost to consider. The typical window treatments cost anywhere from $6 to $550 for materials alone.

Window Placement Considerations
Before installing a shower window, consider practicality. To keep the window drier, consider installing it on a wall near the shower head. Additionally, consider the height at which you want the shower window placed. High, long, thin windows, also known as clerestory windows, are a popular option. These windows allow light into the room while maintaining privacy.

Proper Window Caulking Techniques
Bathrooms tend to be hot and humid, so take the necessary precautions to ensure your shower window is waterproof and mold-resistant. Here’s a step-by-step guide to properly caulking your shower window:
- Assess the current caulk. Before applying a new caulk, check the current caulking for damage or mold. If it has signs of either, you’ll have to remove it. If the old caulk is free of damage and mold, clean and dry it before applying a new bead of caulk.
- Choose the correct caulk. Buy an interior caulk that’s waterproof and resistant to mold. Caulk with acrylic latex or silicone can resist mildew and stick to nonporous surfaces.
- Clean the space around your window. If the space around your window is dirty, the caulk won’t bond to the surface properly. Make sure it’s dry before attempting to seal it.
- Apply the caulk. Cut the tube tip of your caulk and place the tip against the window seam. Slowly fill the seam around the shower window.
- Smooth the caulk. After running the caulk around the window, smooth the caulk with a wet finger or caulk applicator.
- Allow the caulk to dry. Let the caulk dry completely before using your shower. Most caulk will dry within 12–24 hours.
