Common Causes of Damage to a Solid Surface Bathtub

Common Causes of Damage to a Solid Surface Bathtub

  • Drain Overtightening
  • Site Accident and Concealed Freight Damage
  • Thermal Shock

Drain Overtightening

The most common reason for cracks around the drain area is over-tightening the drain during the installation process. If the drain is not closed properly, it can have leakage problems. If you close it too tightly, the chances of your solid surface bathtub breaking is very high. Even in normal bathtubs, it can be an intimidating problem, but you should be even more careful with solid surface bathtubs.

It can either lead to the seal cracking or the bathtub breaking. So make sure not to plug in and tighten or force close the drain too much.

Site Accident and Concealed Freight Damage

This damage happens when you try to change or move the tub from one place to another.

It can be due to the bathtub being moved a lot. It causes chipping, which can happen due to the enamel being worn out. 

Thermal Shock

Solid surface bathtubs can break easily due to thermal shock or mechanical stress that happens when the bathtub is heated or cooled down rapidly. Sudden changes in the temperature, that is, heat or cold, makes the surface of the bathtub contract or expand, which causes cracks on the edges, rim, and drain area.

Solid surface bathtubs are very similar to the elements like glass, natural stone, and ceramics, which has the same characteristics of breaking when there is a sudden and uneven change in the temperature. For example, if you pour ice-cold water into a solid surface bathtub that just had scalding hot water or vice versa, the bathtub will break.
