What Causes a Bathtub to Crack?

If your bathtub is made of porcelain-enameled steel, it can develop cracks over time. The most common cause of these cracks is corrosion from the metal beneath the enamel. This can happen if the tub isn’t properly sealed or if it’s constantly exposed to moisture. Another reason for cracked bathtubs is impact damage. This can occur if something heavy is dropped into the tub or if someone stands on the edge of the tub and puts all their weight on one foot. Finally, bathtubs can also crack due to thermal stress. This happens when the temperature of the tub changes abruptly, such as when hot water is poured into a cold tub. Thermal stress can also cause hairline cracks in bathtubs made of other materials, such as acrylic or fiberglass.

How to Repair a Cracked Bathtub

A cracked bathtub can be a big eyesore in your bathroom. Not only is it unsightly, but it can also be dangerous if not repaired properly. If you have a cracked bathtub, there are a few things you can do to repair it.

First, you will need to clean the area around the crack. Be sure to remove any soap scum or dirt that may be present. You can use a mild cleaner and a soft cloth to do this.

Once the area is clean, you will need to apply a sealant to the crack. There are many different types of sealants available, so be sure to read the instructions carefully before applying. Once the sealant is in place, you should allow it to dry completely before using the tub again.

If the crack is still visible after sealing, you may want to consider painting over it. Be sure to use a waterproof paint that is made specifically for tubs and showers. Apply several coats of paint until the crack is no longer visible.

Once the crack is repaired, it is important to take measures to prevent it from happening again in the future. Be sure to clean your tub regularly and avoid using harsh cleaners or scrubbers on it. Also, avoid putting anything heavy on or near the tub as this could cause another crack to form.

When to Replace a Cracked Bathtub

If you have a small crack in your bathtub, it is possible to repair it with a special epoxy kit. However, if the crack is large or if the damage is extensive, it may be necessary to replace the entire bathtub. In addition, if the bathtub is an antique or otherwise valuable, it may be best to replace it rather than risk further damage.


In conclusion, a cracked bathtub can indeed be repaired in most cases. However, it is important to assess the extent of the damage before attempting any repairs and speaking with an experienced professional may be necessary to ensure that the repair job is done properly. With proper care and attention, a cracked bathtub can often be saved from replacement or returned to its former glory.
