How To Level A Cast Iron Tub: A Step-By-Step Process

Leveling a cast iron tub can be a challenging task, but with the right steps, it can be done successfully. One important thing to note is that a cast iron tub should not be supported by the rim, as it can cause cracks and void the warranty. Instead, it should be supported by the feet. This goes against traditional installation procedures, but it is important to follow the manufacturer’s instructions.

Using metal shims under the feet is recommended by some manufacturers, while others suggest using a mortar base to both level and support the tub. It is important to consider the weight of the tub and the condition of the subfloor before deciding on the best method. Consulting with a plumber is also recommended to ensure proper installation.

Key Takeaways:

  • Follow the manufacturer’s instructions for supporting the cast iron tub.
  • Consider using metal shims or a mortar base for leveling and supporting the tub.
  • Consult with a plumber for expert advice and proper installation.
  • Take into account the weight of the tub and the condition of the subfloor.
  • Properly level the tub to ensure stability and longevity.

Step-By-Step Process for Leveling a Cast Iron Tub

When it comes to leveling a cast iron tub, following a systematic process is crucial to ensure a stable and secure installation. Here are the steps to level your cast iron tub:

  1. Prepare the area: Before starting the leveling process, ensure that the subfloor is clean, dry, and free from any debris. It’s important to have a sturdy and level base to work with.


  2. Inspect the tub: Carefully examine the cast iron tub for any signs of damage or defects. Pay close attention to the feet and check for any cracks or chips that may affect the leveling process.


  3. Position the tub: Place the cast iron tub in its desired location, making sure it aligns properly with the plumbing fixtures. Use a level to check if the tub is centered and levelled.


  4. Adjust the feet: Start by adjusting the feet of the cast iron tub. Turn the adjustable feet clockwise or counterclockwise to raise or lower each corner as needed. Use the level to check the tub’s levelness after each adjustment.


  5. Use shims: If the adjustable feet are not sufficient to achieve a level surface, consider using metal shims. Place the shims underneath the feet to provide additional support and adjust the height accordingly. This will help stabilize the tub and ensure an even weight distribution.



  6. Secure the tub: Once the tub is level and in the desired position, secure it by applying an appropriate adhesive or waterproofing material around the base. This will prevent any movement or shifting over time.


Remember, it’s always recommended to consult with a professional plumber or contractor when leveling a cast iron tub. They can provide expert guidance and ensure that the installation is done correctly, following safety regulations and industry standards.

Tip: When leveling a cast iron tub, it’s essential to prioritize safety and follow the manufacturer’s instructions. Taking the necessary steps to ensure proper support and levelness will result in a durable and long-lasting installation.

Conclusion

Leveling a cast iron tub is a crucial step in the installation process to ensure the tub’s stability and longevity.
