Bathrooms are susceptible to leaky water, and the bathing tub dominates the entire process of the leak. Most people never even realize that the bathtub has a problem until mould develops or water from the ceilings under the bathtub leaks underneath the sinks.

If you feel repair water leaking like it’s yours, then you’re right here. Also, you may have been living at an outdated property and are wondering where the source of leaks is or what the solutions are that could cause this to occur.

If you notice your bathtub leaking from the plumbing wall underneath, it’s important not to ignore the issue, as it can worsen over time and potentially lead to flooding. Here are a few possible reasons for the leakage and what you can do.

Common bathtub leaks, when a bathtub leaks underneath

Cracked Bathtub: Cracks in the bathtub can be hard to spot but can cause significant trouble. To check for cracks, fill the tub with water and observe closely for any areas where water seems to be sucked down. If you find a crack, you can repair it using a bathtub repair kit, available for surface or internal repairs, but to avoid it permanently, we advise you to call a professional.

Leaking Bathtub Taps: Constant dripping from the taps can corrode the surrounding area. This is often caused by worn rubber (old) washers inside the taps. You can try fixing the dripping tap yourself with a screwdriver and adjustable wrench. Be advised, that DIY solutions are only temporary.

Grout Issues: Sometimes, leaks are not related to the pipework but rather the shrinkage of grout. Grout can shrink around the tiles, leading to water seepage. To fix this, regrout the tiles using a mixture of silicone caulking and grout to create a new moisture barrier.

Bath Overflow Pipe Leak: The gasket between the bathtub and the overflow pipe can dry up or crack over time, causing leaks. You can change the gasket yourself with some preparation.

New installation: In some cases, you need a new bath to be installed.

Fixing Bathtub Leaks: Step-by-Step Guide

If The Water Leaks from the Bathtub Drain.

If you notice water leaking from the bathtub drain, several factors could be contributing to the issue. Understanding the causes and implementing appropriate solutions can help address the source of the leak problem. Consider the following:

  • Damaged or Worn-out Drain Components: Over time, the drain components, such as the drain stopper, gasket, or drain pipe, can deteriorate or become damaged, leading to water leakage. Inspect these parts for signs of wear or damage and replace them if necessary.
  • Loose Connections: Loose connections between the drain pipe, trap, or overflow pipe can cause water to leak. Ensure that all connections are properly tightened and secure.
  • Faulty Drain Seal: The drain seal, located underneath the drain flange, may deteriorate or become faulty over time, resulting in water leakage. Replace the drain seal to restore the proper seal and prevent leaks.
  • Improper Installation: In some cases, improper installation of the bathtub drain can lead to leakage. If you suspect an installation issue, it is recommended to consult a professional plumber or your builder to assess and rectify the problem.

By identifying the specific cause of the bathtub drain leakage, you can take appropriate measures to address the issue.

Overflow Drain Leaks ( bathtub leaks)

Leaking from the drain can be a common issue in bathtubs. If you notice water escaping from there, there are a few possible causes and solutions to consider:

It is important to take action promptly. Here are some possible causes and recommended solutions:

  • Components Check: Examine the drain assembly for any loose connections or damaged parts. Ensure all components are properly secured.
  •  Blockage Removal: If there is a blockage in the drain, clear it to restore proper water flow. A plumbing snake or professional assistant can help with this task.
  • Seal Integrity: Over time, the seal around the overflow may degrade, leading to leaks. Replace the seal to establish a reliable and watertight connection.

Taking swift action will help prevent further damage and maintain the functionality of your bathtub. A leaky bathtub or a leaking bathtub overflow pipe requires immediate attention to prevent further damage and potential water-related issues.

Bathtub Itself Leakin

If you are experiencing a bathtub leak, it’s important to take action to prevent water damage. Here are some potential causes and solutions to address a leaking bathtub:

  • Damaged Caulking: Check the caulking around the edges of the bathtub. If it is cracked or worn out, water can seep through. Remove the old caulking and reapply a fresh bead of waterproof caulk to create a proper seal.
  • Cracked Bathtub: Inspect the surface of the bathtub for any visible cracks or damage. If you find any, consider repairing or replacing the bathtub to prevent further leakage.
  • Loose Connections: Check the connections of the plumbing fixtures, such as faucets and drainpipes, attached to the bathtub. Tighten any loose connections to ensure a secure seal and prevent leaks.
  • Faulty Seals: The seals around the bathtub drains, overflow openings, or jets may degrade over time, leading to leaks. Replace these seals to restore their effectiveness and stop the leakage.

Fixing a cracked bath:

If you have a cracked bathtub, it can be a more complex issue to address. Here are some steps you can take:

  1. Assess the Severity: Determine the extent and severity of the crack. If it’s a minor surface crack, you may be able to repair it yourself. However, for significant or structural cracks, it’s best to consult a professional.
  2. Temporary Patch: If the crack is small and you need a temporary solution, you can use an epoxy or bathtub repair kit to seal the crack. Follow the manufacturer’s instructions carefully and ensure the area is clean and dry before applying the patch. Keep in mind that this is not a permanent fix, and you’ll eventually need a more substantial repair or replacement.
  3. Consult a Professional: For more severe cracks or if the temporary patch isn’t holding up, it’s recommended to consult a professional. A professional can assess the extent of the damage and provide appropriate recommendations for repair or replacement.
  4. Repair or Replacement Options: Depending on the severity and location of the crack, there are a few options to consider:
    • Tub Liner: A tub liner is a custom-fit acrylic or PVC liner that can be installed over the existing tub. It covers the crack and provides a new surface. However, this option may slightly reduce the size of the bathtub.
    • Fibreglass Repair: A professional can repair the crack using fibreglass and resin, reinforcing the damaged area and restoring its structural integrity. This process requires specialized skills and equipment.
    • Bathtub Replacement: In cases of extensive damage or if you want a long-term solution, replacing the bathtub might be the best option. A professional plumber or contractor can assist with selecting a new bathtub and ensuring proper installation.

Remember, cracks in a bathtub can lead to water damage, so it’s essential to address the issue promptly. Seek a professional.
