Planning a bathroom renovation? Safety is just as important as style. When it comes to bathroom windows, using tempered glass isn’t just a smart choice—it’s often required by building codes. At Window World of Muscle Shoals, we’re here to explain when bathroom windows must be tempered, what tempered glass is, and how it benefits your home’s comfort, safety, and value.
What is Tempered Glass?
If you’re not familiar with it, tempered glass (which is a safety glass) is stronger than typical glass. Even if it does break, it only creates small, round pieces or pellets (rather than sharp shards that get all over your floor). Here’s everything you need to know when considering it for your bathroom windows, including tempered window glass legal requirements.
When are Tempered Glass Windows Most Beneficial?
Tempered glass is more resilient to damage than traditional glass, producing fewer pieces when shattered. This makes it especially safe for use in bathrooms, where bare feet need to be protected. Tempered glass can be especially beneficial in the following circumstances:
When You’re Dealing With Weather Issues
Tempered glass is engineered to resist breakage from hail, high winds, and flying debris—making it an excellent choice not just for bathrooms, but for any window exposed to severe weather.
When Is Tempered Glass Required by Code?
According to International Building Code, if you have any fixture with a door (bathtub, shower, sauna, etc.), any window less than 60 inches above the floor must be tempered. Additionally, if a window meets all of the following criteria, it legally needs to be tempered.
- Its bottom is less than 18 inches above the floor.
- Its top is less than 36 inches above the floor.
- Its size is greater than 9 feet.
- It’s within 36 inches of where you walk.
If you’re unsure if your current windows are tempered or not, look for a stamp in the corner or a label that tells you the window’s properties. As part of your free window estimate, we can also help you evaluate your space and let you know where you may need tempered windows.
Other Places Tempered Glass Is Needed in the Bathroom
Besides windows, tempered glass is typically required for:
- Shower doors and enclosures
- Glass panels near tubs
- Bathroom mirrors above a certain size
- Skylights in bathrooms
Installing the correct type of glass isn’t just a smart choice—it’s a safety requirement.
