Imagine you are taking a relaxing bath after a long day. The hot water feels great on your skin, and you are starting to feel more relaxed by the minute. Suddenly, you notice a hairline crack in the side of the tub. Or worse, your bathtub starts leaking water onto the floor! This can be a frustrating and even dangerous situation.

But why does this happen? Is it because you are using your tub too much? Is it because of a manufacturing defect? Or is there something else going on? There are a few different reasons why your bathtub may be cracking. Here are some of the most common causes:

Improper Installation

Installation is one of the most common elements affecting plumbing fixtures’ durability and functionality. Some people try to cut corners by doing their plumbing or hiring an inexperienced plumber. This can lead to big problems down the road, including cracks in your bathtub.

The installation process is quite complex. The tub has to be level, properly anchored, and supported to withstand the weight of water and people. If the tub isn’t level, it can put stress on the sides and cause them to crack. The same is true if the tub isn’t supported properly. The tub’s weight can cause the floor to sag, putting pressure on the sides and leading to cracks. In addition, if the tub isn’t sealed properly, water can seep behind the walls and cause them to buckle and crack. To avoid these problems, hire a qualified plumber in Jacksonville, FL, to install your bathtub. With proper care and installation, your tub will provide years of enjoyment.

Poor Quality Material

Another possible reason your bathtub has cracked is that it is made of poor-quality material. When products are made quickly and cheaply, they often do not stand the test of time. This is especially true for items exposed to water and heat, like bathtubs. Over time, the cheaper materials will start to break down and show signs of wear and tear. If you have a bathtub made of poor-quality materials, it is more likely to develop cracks and other damage.

In contrast, a bathtub made of high-quality materials will be more durable and resistant to damage. If you want your bathtub to last for many years, make sure it is made of high-quality materials. You should consult a professional plumber to help you choose a tub that will be durable and long-lasting.

Harsh Chemicals

Bathtubs are often exposed to harsh chemicals, like bleach and cleaning products. These chemicals can break down the tub’s material and cause it to crack. In addition, using these products too frequently can damage the tub’s finish and make it more susceptible to cracks. To avoid this problem, use milder cleaning products on your tub and avoid using bleach or other harsh chemicals. You should also rinse the tub after each use to remove residual chemicals.

Impact Damage

When you think of why your bathtub may crack, impact damage is probably not the first thing that comes to mind. However, impacts can cause cracks in both acrylic and enameled tubs. If something falls into the tub or drops something heavy onto the tub, it can put stress on the material and cause it to crack. Because impact damage is often not covered by warranties, it is important to be careful when using your tub and avoid any actions that could stress the material. If you impact the bathtub accidentally, get a plumber in Jacksonville, FL, to inspect for any damage and make repairs as needed.


As bathtubs age, they become more susceptible to damage. The material can break down over time and become weaker. In addition, the finish on the tub can start to wear off, making it more vulnerable to scratches and other damage. If your bathtub is starting to show signs of age, be sure to take good care of it and have it inspected regularly by a professional plumber. Proper care includes cleaning the tub regularly, using mild cleaning products, and avoiding any actions that could stress the material. If you notice that it can’t hold it anymore, it’s time to replace it.

Natural Disasters

While it is not common, natural disasters can cause damage to bathtubs. Depending on the disaster, different types of forces are exerted on buildings which can cause cracks. For example, during an earthquake, the ground shaking creates vibrations that travel through the foundation and into walls, floors, and ceilings; these vibrations can cause cracks in a bathtub. Similarly, high winds associated with hurricanes and tornadoes can also put stress on a structure and lead to cracks.

To avoid disaster-related damage to your home, take precautions such as reinforcing doors and windows and anchoring your home to the foundation. However, even with these measures, there is always a chance your bathtub could crack due to forces beyond your control. Hiring a plumber to inspect your plumbing system after a disaster is important. Your bathtub should be included in this inspection to ensure it has no damage.

Take Action Immediately

If you notice a crack in your bathtub, the first thing you should do is contact a professional plumber. Cracks can quickly become worse and lead to leaks. Once a crack starts leaking, water can cause damage to the surrounding area and create an ideal environment for mold and mildew to grow. In addition, cracks can also become breeding grounds for bacteria. Therefore, it is important to take action immediately and have the crack repaired by a professional plumber.
