Preparation: Removing the Old Toilet

Begin by turning off the water supply and flushing the toilet to empty the tank. Use a bucket to catch any remaining water. Disconnect the water supply line and remove the bolts connecting the toilet to the floor. With the help of a partner, tip the toilet forward and remove it.

Inspect and Prepare the Floor

Inspect the floor for any damage or unevenness. If necessary, level the surface using a self-leveling compound. Ensure the floor is clean and dry before proceeding.

Install the Wax Ring

The wax ring creates a seal between the toilet and the drain. Center the wax ring on the drain, ensuring it's flush with the floor. Be careful not to damage the wax ring during this process.

Position and Secure the Toilet

Carefully position the new toilet over the wax ring, ensuring the bolts align with the holes in the floor. Gently lower the toilet onto the wax ring, applying even pressure to create a proper seal. Tighten the bolts using a screwdriver and adjustable wrench, but be careful not to overtighten and crack the toilet base.

Test the Installation

Slowly turn the water supply back on and check for any leaks around the base of the toilet or the water supply line. Flush the toilet to ensure it's functioning correctly. If there are no leaks and the toilet flushes as expected, your installation is complete!

Optional: Install a Toilet Seat

If your toilet didn't come with a seat, or you'd like to upgrade, measure the seat bolts to ensure you purchase the correct size. Align the seat with the bolts, place the washers and nuts on the bolts, and tighten securely using a screwdriver.

Congratulations! You've successfully installed a new toilet. Regular maintenance, such as cleaning and checking for leaks, will ensure your toilet continues to function properly and efficiently. Happy DIY-ing!
