The shower room is loved by consumers for its advantages such as small space, but it is disturbing that the shower door glass has a spontaneous explosion rate of 3‰,whether it’s frameless shower door or framed ones. If you are not careful, your personal safety will be threatened. “Why does shower door glass explode?” The quality and safety of the shower room has become the most concerned issue for consumers
CASE STUDY :People get hurt for glass explosion.
Last month, Ms. Wong gave the child a bath at home, but the family were all injured.
Ms. Wong “I was about to close the door and found that the door magnet didn’t work.Unexpectedly, just after Ms. Pei’s husband’s hand was placed on the tempered glass door ,the glass exploded.The glass exploded from the middle and all hit my back.
Ms. Wong’s back, legs and hands were all scratched by glass, and there were obvious wounds on her husband’s arms.

What caused shower door glass explosion?
Why does the shower room explode? Many people naturally associate the shower room with the temperature difference? Is it really? Next, use three experiments to prove, everyone pay attention to it~
Test 1:Is the shower room explosion caused by uneven heating?
In the hot summer, the highest temperature of the glass surface is about 65℃.
When hitting the tempered glass with a hammer a few times, and the glass was intact.
Hitting tempered glass at 65 degree
Next, start to heating the glass with a spray gun for 10 minutes until the glass temperature reaches 300°C, but there is no problem.
heating glass to 300 degrees
This also means that the temperature will not leading to tempered glass spontaneous explosion.
Now let’s see if the shower room bursts due to the alternating cold and hot in the bathroom?
We use cold water to pour directly on the glass in the high temperature of 300 ℃. the tempered glass suddenly encountered cold water but smoked a little, but did not burst.
cold water cannot cause glass breakage
In fact, high-quality tempered glass encountered a heating process (650-700 degrees) and fast cooling process,After a special process, the general temperature will not cause the tempered glass to explode.
Test 2:Is the shower room explosion caused by float glass quality?
The deciding reason for glass spontaneous explosion is the float glass used, because the float itself contains impurities—nickel sulfide. The more impurities and bubbles, the higher the rate of spontaneous explosion.
Next, use low-quality tempered glass that is cheaper and has obvious impurities to continue the experiment.
impurity inside glass
The tempered glass temperature has increased by 200℃, and pour cold water on the glass.
When cold water touched the glass, the glass broke and collapsed in less than 2 seconds.
poor quality glass broken under cold water
There are sulfide stones in this glass. After the experiment, the sulfide stones cause micro-cracks in the glass, which causes the glass to explode spontaneously.
Uneven heat and cold is the inducement of the glass explosion, and the fundamental reason is bad glass quality. There are impurities in the float glass, which will change the stress of the whole glass and cause spontaneous explosion when affected by the temperature difference. Therefore, do not buy cheap shower room.
Test 3:Improper installation also leading to glass explosion.
Two pieces quality tempered glass, the same size and the same thickness,.
One piece without any processing.
The other one is reinforced at 4 corners, 3 loose and 1 tight, let’s see if there is any glass firmness difference.When installing reinforced tempered glass, it is required to to have even force around it. But testers deliberately tightened the screw in one of the corners to simulate improper installation.
glass test 3 to test if installation affect glass strength
The tempered glass that has not been treated has been smashed a lot and no broken.
glass impact test-untreated glass
The reinforced toughened glass broke very soon.
Therefore, toughened glass that looks very durable will become very fragile as long as the stress structure changes.
This shows how important shower room installation is. Therefore, everyone must go to the physical store to buy the shower room. Not only can you intuitively see the quality , but also the physical store can give you professional services.
Below is the full process of the test:

How shall we purchase the right shower door?
Check glass quality.
- A good shower room has transparent glass and no defects such as dots and bubbles.
- There is tempering logoon the glass corner.

Check aluminium profiles
- Look at the hardness of aluminum
The thickness of the qualified shower room aluminum profile is above 1.2mm,The hardness of aluminum can be tested by pressing the aluminum frame by hand. Aluminum with a hardness of 13 degrees or more is difficult for an adult to deform by pressing it by hand.
- A good shower room has a smooth surface, no chromatic aberration and perfect surface treatment.
shower room with aluminium profiles and hardware
Check the hardware
The slider and the track should be closely matched, with a small gap, and not easy to fall off when impacted by external forces to avoid safety accidents. Use 304 and even 316 stainless steel hardware to ensure quality.
Check shower door water tightness
The main checking points of the water tightness of the shower room are
- The connection between the shower room and the wall
- The joint between the door and the door
- The connection between the shower room and the stone base and the bottom basin
- Check the sealability of the rubber strip and the rubber strip
