Initial Assessment and Preparation

Site Inspection:

  • A thorough inspection of the bathroom space is conducted.
  • During the inspection, the plumber evaluates not only the space where the new toilet will be installed but also the condition of related plumbing fixtures.
  • The plumber checks existing plumbing setups, measures the area for the new toilet, and assesses the condition of the flooring and flange.
  • This evaluation helps identify potential challenges that may require special attention during installation.
  • They also ensure that the ventilation and lighting are adequate for installation work.
  • Proper ventilation and lighting are critical to ensuring that the installation proceeds safely and effectively.

Choosing the Right Toilet:

  • The plumber recommends a toilet based on the bathroom’s specifications and the customer’s preferences.
  • This recommendation is tailored to align with the user’s expectations and the technical requirements of the bathroom layout.
  • Considerations include the toilet’s water efficiency, height, design, and how well it matches the existing bathroom décor.
  • Factors such as the toilet’s flushing technology and eco-friendliness are also taken into account to provide a durable and sustainable solution.

Preparation of Tools and Materials:

  • Necessary tools such as wrenches, screwdrivers, and possibly a power drill or saw are gathered.
  • These tools are essential for handling various aspects of the installation process, from removing the old toilet to securing the new one.
  • Materials like a new wax ring, mounting bolts, and a flexible water supply line are prepared.
  • Proper preparation of materials ensures a smooth installation process without unnecessary delays.
  • The plumber ensures all components and replacement parts are at hand to avoid interruptions during installation.
  • Having everything readily available helps streamline the installation process and reduces the risk of errors.

Removal of the Old Toilet (if applicable)

Shutting Off Water:

  • The water supply to the toilet is shut off to prevent any spills during the removal process.
  • This step is crucial for avoiding water damage and ensuring a clean working environment.
  • This usually involves turning a valve located behind the toilet or near the bathroom’s water inlet.
  • Properly shutting off the water supply is vital to prevent flooding during the disassembly of the old toilet.

Draining and Disconnecting:

  • The tank is flushed to drain the water, and any remaining water is mopped up with a sponge or cloth.
  • This ensures that the removal of the toilet is mess-free and environmentally conscious.
  • The supply line is then disconnected using an adjustable wrench, ensuring no water leaks onto the floor.
  • Careful disconnection prevents damage to the plumbing system and supports a straightforward reinstallation.

Unscrewing and Lifting:

  • The toilet is detached by unscrewing the bolts that fix it to the floor.
  • The plumber exercises caution to preserve the integrity of the bathroom floor and surrounding area.
  • The plumber carefully lifts the toilet to avoid damage to the bathroom flooring.
  • Correct lifting techniques are employed to prevent personal injury and damage to the toilet itself.
  • The area is then cleaned, and the plumber checks the floor for any damage or irregularities that need addressing before installing the new toilet.
  • Cleaning and checking ensure that the new toilet has a solid and level foundation for installation.

Installing the New Toilet

Preparing the Flange:

  • The condition of the flange is inspected for any signs of wear or damage.
  • This inspection is crucial as the flange must provide a secure connection to prevent leaks.
  • It’s cleaned to remove any debris that might prevent a good seal with the new wax ring, and replaced if found defective.
  • A clean and intact flange is essential for the long-term performance and hygiene of the new toilet.

Placing the Wax Ring:

  • A new wax ring is placed over the flange to ensure a watertight seal between the toilet and the plumbing system.
  • This step is critical as it ensures that no leakage occurs at the base of the toilet.
  • The ring must be centered perfectly to avoid leaks.
  • Correct placement of the wax ring is crucial for preventing future leaks and odors.

Setting the Toilet:

  • The new toilet base is aligned carefully with the flange and wax ring.
  • Proper alignment is necessary to ensure the toilet functions correctly.
  • The plumber applies even pressure on the toilet to set the seal properly without shifting the wax ring from its position.
  • Applying even pressure ensures that the seal is airtight and secure, which is essential for the proper operation of the toilet.

Securing the Toilet:

  • The toilet is bolted securely to the floor, ensuring it is stable and level.
  • Stability and leveling are critical to avoid any movement that could compromise the wax seal.
  • Excess bolt length may be trimmed to prevent tripping hazards and improve aesthetics.
  • Trimming the bolts enhances the finished look of the installation and ensures safety in the bathroom.

Attaching the Tank:

  • If the tank and bowl are separate, the tank is then mounted onto the base.
  • This process must be handled with care to avoid damaging the tank or bowl.
  • The plumber uses bolts to secure the tank, checking that it’s aligned correctly and there are no gaps.
  • Ensuring that the tank is securely attached and properly aligned prevents leaks and maintains the efficiency of the flushing system.

Connecting the Water Supply:

  • The water supply line is reconnected to the tank, ensuring a snug fit to prevent leaks.
  • A secure connection is vital to avoid water damage and ensure the toilet operates correctly.
  • The plumber turns the water back on and inspects the connection for any drips or leaks.
  • Checking for leaks after reconnecting the water supply ensures that all connections are secure and the toilet is ready for use.

Final Testing:

  • The installation is tested by flushing the toilet multiple times.
  • Multiple flushes are necessary to verify both the correct water flow and the integrity of the installation.
  • The plumber checks for leaks around the base and the supply line and ensures that the toilet flushes correctly and refills at the appropriate level.
  • Testing is crucial to confirm that the installation has been successful and the toilet is fully operational.

Conclusion and Clean-Up


  • All installation debris is removed, and the work area is cleaned.
  • A clean installation site is as important as the technical installation itself, providing a professional finish.
  • Tools are collected and stored properly to leave the bathroom tidy and ready for use.
  • Proper tool management prevents accidents and ensures the plumber is prepared for the next job.

Customer Walkthrough:

  • The plumber demonstrates the new toilet’s functionality to the customer.
  • Demonstrating the toilet’s functionality ensures that the customer is satisfied and knows how to operate their new fixture.
  • Maintenance tips and care instructions are provided to help the customer maintain the toilet in good working condition.
