Before setting the toilet, remove the rag you placed in the drain pipe. Carefully lift the toilet bowl, keeping it as level as possible. Look over the bowl to align the holes in its base with the closet bolts sticking up from the floor. Lower the toilet straight down onto the bolts. Once it's in place, press down firmly on the toilet bowl with your body weight to compress the wax ring and create a seal. Use a tape measure to check that the toilet is parallel with the wall behind it.

Goal: Position and set the toilet bowl onto the floor flange.

  • Toilets are heavy. It may be helpful to have a second person assist with lifting and positioning the bowl.
  • Do not rock or twist the toilet once it is placed, as this can break the wax seal. If you need to reposition it, you should use a new wax ring.

FAQs

Why is a toilet flange extender needed, and what's the typical time commitment for this beginner-level project?

A toilet flange extender like the Oatey 1/4 in. PVC Toilet Flange Spacer is needed when new, thicker flooring causes your existing flange to sit below the finished floor level, preventing a leak-proof seal. This project is considered beginner-friendly, mainly requiring basic hand tools and careful attention to detail. Expect to dedicate 1-2 hours for the installation once the toilet is removed and the area is prepped.

Which specific tools and materials are most critical for successfully installing the flange extender and ensuring a leak-proof seal?

Key tools include a Husky 10 in. Adjustable Wrench for bolts, an HDX 6-in-1 Screwdriver, and a JES 10 oz. 12:1 Caulk Gun for the silicone sealant. Crucial materials are the Oatey 1/4 in. PVC Toilet Flange Spacer itself, an Everbilt Extra Thick Toilet Wax Ring with Plastic Horn, and Everbilt 1/4 in. x 2-1/4 in. Toilet Floor Bolts for securing everything.

What are the biggest mistakes to avoid during installation to prevent future leaks?

The most common mistakes are failing to thoroughly clean and dry the existing flange before applying silicone, or neglecting to dry-fit the extender to ensure it's flush with the finished floor. Always use a fresh, high-quality Everbilt Extra Thick Toilet Wax Ring and ensure the closet bolts are tightened evenly without over-tightening, which can crack the toilet base.

What essential safety steps should I take before and during the flange extender installation?

Always begin by shutting off the water supply to the toilet and flushing to empty the tank and bowl completely. Wear FIRM GRIP Pro Cleaning Disposable Nitrile Gloves for hygiene and protection. Be mindful of lifting the toilet, which can be heavy, and ensure a stable, dry work area to prevent slips.
