A low toilet flange can lead to various plumbing issues, including leaks and improper flushing. If you’re facing this problem, don’t worry – it’s a common issue that can be fixed with the right approach. In this blog, we’ll explore how to fix a low toilet flange and ensure your bathroom’s plumbing is in top shape.

Title: A Step-by-Step Guide to Fixing a Low Toilet Flange

  1. Assess the Situation: Before you begin, inspect the toilet to determine if the flange is truly low. If the toilet wobbles or there is a visible gap between the base and the floor, you likely have a low flange issue.
  2. Gather Your Tools: You’ll need a wax ring, a toilet flange extender kit, a wrench, a plunger, and a putty knife.
  3. Remove the Toilet: Turn off the water supply, flush the toilet to drain the tank and bowl, and disconnect the water line. Carefully remove the toilet and set it aside.
  4. Inspect the Flange: Check the condition of the flange. If it’s broken or damaged, you may need to replace it. If it’s simply lower than the floor, proceed to the next step.
  5. Install a Flange Extender: A toilet flange extender is designed to raise the height of the flange to match the floor level. Follow the manufacturer’s instructions to properly install the extender.
  6. Replace the Wax Ring: Place a new wax ring on the horn of the toilet flange extender. The wax ring creates a watertight seal between the toilet and the flange.
  7. Reinstall the Toilet: Carefully lower the toilet onto the wax ring and toilet flange extender. Apply gentle pressure to ensure the wax ring seals properly.
  8. Secure the Toilet: Use the provided bolts and washers to secure the toilet to the floor. Tighten the nuts evenly to avoid cracking the toilet base.
  9. Reconnect and Test: Reconnect the water line, turn on the water supply, and flush the toilet. Check for any leaks around the base and ensure the toilet sits firmly on the floor.


Fixing a low toilet flange is a manageable task that can save you from potential plumbing headaches. By following these steps and paying attention to detail, you can restore your toilet’s stability and prevent any future issues related to a low flange.
