1. Installing the Toilet Flange Before Flooring:

Installing a toilet flange before flooring is a common practice to ensure a clean and secure connection between the toilet and the sewer line while maintaining a professional finish. Here are the steps to install a toilet flange before installing flooring:

Materials and Tools Needed:

  • Toilet flange
  • Wax ring
  • Flange bolts
  • Adjustable wrench
  • Screwdriver
  • Measuring tape
  • Saw (if necessary)

Install Steps Toilet Flange Before Flooring:

01. Prepare the Area:

Begin by removing the old toilet and cleaning the area where the new flange will be installed. Ensure that the subfloor is level and in good condition.

02. Determine Flange Placement:

Measure the rough-in distance, which is the distance from the wall to the center of the drain pipe. This measurement will help you position the flange correctly. Mark the location on the subfloor.

03. Cut the Waste Pipe (if needed):

If the existing waste pipe is not at the correct height, you may need to cut it down to the appropriate level using a saw. The top of the flange should sit flush with or slightly above the finished floor.

04. Install the Flange:

Place the flange over the waste pipe, ensuring that the slots for the flange bolts are aligned with the toilet’s mounting holes. Secure the flange to the subfloor using screws or bolts, making sure it is level and properly aligned with your reference marks.
