Bathroom Windows - 3 Factors to Consider

Posted on November 15, 2019

Muscatine, IA Bathroom Window Replacement

One of the trickiest places to install new or replacement windows is the bathroom. Choose the wrong window, and you could end up with mold or mildew problems or your privacy could be threatened. But what factors do you need to consider when choosing a bathroom window? And what's the right window option for your bathroom?

Window Condensation

You may have noticed car windows or even windows in other rooms of your home that fog up during winter. This is caused by the heated air on the interior meeting with the cold exterior temperatures, and it can be quite a threat when it comes to your bathroom. Temperatures in your bathroom can change drastically when you turn on the shower. Bathroom windows are also vulnerable to window condensation because people usually shower either at night or in the morning, when outdoor temperatures are coolest.

You want windows that have the warmest possible interior glass, so windows that have a low U-Factor and low air leakage. One thing that might help is double pane windows, often with krypton or argon gas in between to slow the flow of air through the glass panes. Insulating glass could also be helpful here.


This one goes hand-in-hand with the above problem, as the former is often a symptom. Because of all the moisture and warmth from your bathroom when you bathe or shower, humidity is a natural challenge. When your bathroom isn't properly ventilated, it can lead to problems of mold or mildew that can be destructive to your home as well as your respiratory health. 

It's for this reason that bathrooms often have fans and it's recommended that the fans be used while showering or after showering. You can also find windows that have good ventilation options, such as double hung or casement windows, to better air out your bathroom.


A final factor to consider is privacy. It's good to have windows in your bathroom, to offer more lighting, pleasant views, and ventilation. However, the last thing you want is for someone to look in on you while you're showering. Often, privacy can come down to the placement of the window and the size of the window. You can also opt for window treatments that will offer you the opportunity to customize your privacy, so long as you make sure to frequently ventilate your bathroom. Another option is glazed glass or decorative glass that allows you to let in light while not giving those on the outside a clear view into your bathroom.

Your choice of bathroom windows shouldn't be taken lightly. Make sure you consider the best windows when it comes to insulation, ventilation, and privacy for the winning combo in your bathroom.
