A bathroom window is one of those polarizing features that elicit strong reactions from homeowners. Some view a window in the bathroom as a delightful design accent that ushers in natural light. Others see it as an impractical element that compromises privacy. So which is it – helpful highlight or hazardous hassle? We’ll examine the pros and cons so you can decide if a bathroom window is right for your home.

The Benefits of a Bathroom Window

Here are some potential upsides to including a window in your bathroom design:


A window provides necessary ventilation, helping control humidity and preventing mold growth. Bathrooms generate a lot of moisture from hot showers, so having a way to circulate fresh air is important. This is especially critical if your bathroom lacks an overhead vent fan.

Natural Light

Windows usher in natural daylight, making the space feel bright and airy. This creates a more pleasant ambiance than the harsh glare of artificial lighting alone. It can also make the room feel larger.


A bathroom window provides an opportunity to enjoy a lovely view. Whether it’s looking out over your backyard or taking in an interesting cityscape, a window offers visual interest.


In an emergency such as a fire or power outage, a window gives you another way out of the bathroom if the door is blocked. This secondary exit route improves safety.

Drawbacks of a Bathroom Window

However, there are also some potential downsides with bathroom windows to consider:


Lack of privacy is a top concern. You usually don’t want onlookers being able to peer into your bathroom, so windows need shades, frosting, or another solution.

Steam and Moisture

The hot, humid environment in a bathroom can cause issues for windows. Moisture condensation on the glass and windowsills promotes mold growth. And frames can warp over time. Proper ventilation is key.


Windows involve extra construction costs during a bathroom remodel. And because of the hot, wet conditions, they usually need upgrading to double-paned, tempered glass.


Windows must be cleaned and caulked regularly to look their best and prevent leaks. Steamy bathrooms make windows prone to mineral deposits and soap scum buildup.

Key Factors to Consider

When deciding if you should include a window in your bathroom, keep the following factors in mind:

  • Privacy – Make sure the window doesn’t allow views into the room from nearby windows or high-traffic areas. Solutions include small windows, high windows, obscured glass, and strategic shade placement.
  • Purpose – Decide if the window is mostly for looks or to serve a needed ventilation role. Optimize size and placement accordingly.
  • Moisture prevention – Select windows designed for wet environments. Use exhaust fans and enable airflow.
  • Easy cleaning – Choose accessible windows that can be easily cleaned inside and out.
  • Costs – Weigh expenses like tempered glass and custom sizes vs. the benefits.
  • Alternatives – If privacy or cost is an issue, consider skylights or clerestory windows near the ceiling as alternatives.

Window Styles for Bathrooms

If you opt to include a bathroom window, you’ll have several style options:

  • Double-hung windows – Traditional choice; allows both panes to open for ventilation.
  • Casement windows – Hinged side-opening panes that allow wide ventilation.
  • Awning windows – Top-hinged windows that open outwards. Let in air while maintaining privacy.
  • Hopper windows – Bottom-hinged windows hinged at the bottom to open inwards. Good for high window placement.
  • Glass block windows – Offer obscured light while preventing views in/out. Limit ventilation.
  • Skylights or clerestory windows – High windows near the ceiling are great for natural light but maintain privacy.

Best Practices for Bathroom Windows

To leverage the benefits of a bathroom window while minimizing drawbacks:

  • Position high on the wall or near the ceiling for privacy.
  • Use textured, obscured, or frosted glass treatments.
  • Select water-resistant window frames like vinyl or fiberglass.
  • Include shades or blinds for adjustable privacy control.
  • Use a powerful ventilation fan able to completely exchange air.
  • Opt for double-paned windows with Low-E coatings to reduce condensation.
  • Install windows that are easy to reach and clean.

A Window Above the Bathroom Sink: Feature or Flaw?

Specifically, let’s examine the pros and cons of a window situated above the vanity.


  • Allows natural light during daily grooming routines.
  • Provides desirable ventilation near humidity source.
  • Offers a view while at the sink.
  • High positioning maintains privacy.


  • Can highlight messy counters.
  • Exposes window to splashes and spills.
  • Reduced privacy if visable from other windows.
  • Needs moisture resistant window and sill.


The debate over bathroom windows remains heated. A well-placed window with privacy solutions can absolutely be a stylish feature that brightens the space. However, windows in wet areas involve tradeoffs that may not make them suitable for every homeowner. Assess your needs, bathroom design, and maintenance commitments to determine if the rewards outweigh the risks. With smart planning, a bathroom window can contribute beautiful form and useful function.

Frequently Asked Questions About Bathroom Windows

What size bathroom window is best?

For ventilation purposes, a good rule of thumb is to have a window that is at least 4% of the total square footage of the bathroom. A 10 square foot window is recommended for a mid-sized (50 square foot) bathroom.

Should bathroom windows open?

Yes, having operable windows that open for ventilation is ideal. However, if privacy is a concern, consider clerestory windows or using obscured glass.

Where should a bathroom window be located?

Near the tub or shower is optimal for humidity control. High on the wall or near the ceiling maximizes privacy while allowing light.

Should a bathroom window have a sill?

Yes, a sloped windowsill helps protect the window framing from moisture exposure. Choose water-resistant materials like marble or tile.

What glass is best for bathroom windows?

Tempered glass, which is stronger and safer, should be used. For privacy, textured glass, frosted glass, or patterned glass will obscure views.

Do bathroom windows need special cleaning?

Yes, bathroom windows tend to accumulate mineral deposits, soap scum, and mildew. Use a squeegee, vinegar, and specialized glass cleaners to maintain windows.
