5. Position the Stone Bathtub

Now comes the exciting part—positioning the heavy stone bathtub in its designated spot. Follow these steps:

6. Secure the Stone Bathtub

Once the stone bathtub is in position, it's essential to secure it firmly. Follow these steps:

  • Anchor the bathtub: Use brackets or mounting hardware specifically designed for heavy stone bathtubs to anchor it securely to the floor or walls. This step provides stability and prevents any shifting or movement over time.
  • Connect the plumbing: Reconnect the plumbing fixtures, including the faucets, drain, and water supply lines. Ensure they are tightly secured and properly sealed to prevent leaks.

7. Seal and Finish

The final step involves sealing and finishing the installation. Follow these guidelines:

  • Apply caulk: Use a high-quality waterproof caulk to seal the edges of the bathtub, ensuring a watertight seal. This step prevents water from seeping into the gaps and causing damage.
  • Test for leaks: Once the caulk has dried, turn on the water supply and test for any leaks. Check all connections and fixtures, making adjustments if necessary.
  • Clean and polish: Clean the stone bathtub with a mild, non-abrasive cleaner, and polish it to bring out its natural beauty. Follow the manufacturer's instructions for maintenance and care.
