Why Do Some RV Glass Showers Shatter Spontaneously?

Tempered glass used in many RV bathrooms can actually shatter spontaneously, leaving you to clean up a giant mess. Let’s learn how this happens and what you can do to try to prevent it.

You won’t find a plastic shower door shattering spontaneously. You probably won’t have many problems at all. On the other hand, tempered glass is notorious for breaking without warning. Let’s learn why.

Glass expands and contracts with fluctuating temperatures. If there is no space in the frame to allow this shift, the tempered glass will break.

No Room for Expansion in the Frame

During the glassmaking process, nickel sulfide stones sometimes form as a result of the stainless steel machines. Over time, these stones can morph, causing internal stress.

Internal Stress of the Glass

If there is damage on the edge of the glass, this can lead to problems down the road. So it’s important to inspect the quality.

Damage on the Edges of the Glass

Intense heating and cooling during the glassmaking process make tempered glass strong.

Thermal Stress in the Glass

Sometimes the glass comes defective. Although this isn’t common, it is another reason why glass showers may spontaneously shatter.

Regularly inspect the edges of the shower doors and have safety film installed on the glass door.
