While hairline cracks on a tub are not always an immediate cause for concern, it’s essential to monitor them closely and take necessary action if they worsen or pose a risk to your bathroom’s functionality. Check also: How To Get Rid of Ants in Bathroom.
Why is my Plastic Bathtub Cracking?
Plastic bathtubs can crack for several reasons, and understanding the underlying causes can help prevent further damage and guide you in deciding how to address the issue. Here are some common reasons why plastic bathtubs might crack:
1. Age and Wear
Age and wear are inevitable companions. Over time, even the sturdiest of materials start to show signs of fatigue. This is no different for plastic bathtubs, which may begin to crack after years of use.
While it’s easy to blame poor quality or improper installation, there is another factor that often goes unnoticed: constant thermal expansion and contraction. Plastic expands and contracts with changes in temperature, and this repetitive process can weaken the material over time, leading to cracks. Check also: Best Waterproof Membrane for Shower.
2. Temperature Changes
Plastic expands and contracts with the fluctuations in temperature, causing stress on its structure. When exposed to extreme temperatures, such as hot water or freezing conditions, the plastic can expand or contract rapidly, leading to cracks.
3. Installation Issues
During the installation process, if the bathtub is not properly supported or anchored to the floor, it may flex or shift when weight is applied. This constant movement can put stress on the material and eventually lead to cracks.
Additionally, if the tub is not level or has been improperly installed against walls or other fixtures, it can create tension points that weaken the structure over time. Check also: Replace Rubber Seal Around Shower Glass.
One of the main culprits is impact, which can result from dropping heavy objects on the surface or accidentally hitting it with force. Even a seemingly harmless slip in the shower can create enough impact to cause cracks over time.
Moreover, the quality of the plastic used in your bathtub also plays a significant role. Low-quality or brittle plastic is more prone to cracking under minimal pressure.
5. Chemical Exposure
Chemical exposure can be a hidden culprit behind the cracking of plastic bathtubs, taking homeowners by surprise. The chemicals found in cleaning agents, beauty products, and even tap water can slowly degrade the plastic surface over time.
It’s essential to pay attention to the types of cleaners used on your bathtub to prevent any potential damage. Harsh chemicals like bleach and ammonia should be avoided as they can weaken the plastic and lead to cracks.
Furthermore, certain beauty products that contain strong acids or solvents can also contribute to the deterioration of the tub’s material. Hair dyes, nail polish removers, and even some perfumes may contain chemical components that react negatively with plastic surfaces when exposed for extended periods.
Therefore, it is crucial to rinse off any residue immediately after using these products in order to protect your bathtub from potential harm.
In addition to domestic sources of chemical exposure, tap water itself may contain substances that can weaken plastics over time. Certain minerals like calcium and magnesium in hard water formations gradually accumulate on the tub’s surface through repeated use.
These mineral deposits act as corrosive agents when combined with other contaminants present in household cleaning supplies or personal care items.
6. Vibration or Movement
Plastic bathtubs are a popular and affordable option for homeowners, but they can be prone to cracking. One of the main reasons for this is vibration or movement.
When a bathtub is not properly secured or installed on an unstable surface, it can experience constant vibrations from people walking around or even the water running through the plumbing. Over time, these vibrations can cause stress cracks in the plastic material.
