Quick answer (read this first)
- Verify the rough-in distance before purchase.
- Always use a new wax ring for a watertight seal.
- Ensure the floor flange is undamaged and level.
- Hand-tighten bolts, then apply a final quarter turn.
- Conduct thorough leak checks immediately after installation.
Safety first
- Wear protective gloves to prevent contact with germs and sealants.
- Ensure adequate bathroom ventilation to disperse fumes.
- Lift the commode carefully; it is heavy and awkward to maneuver.
- Completely turn off the water supply to the bathroom before starting work.
- Avoid overtightening bolts, as this can easily crack the commode’s porcelain base.
Tools you may need
- Adjustable wrench
- Flathead and Phillips head screwdrivers
- Putty knife or scraper
- New wax ring (with or without horn)
- Measuring tape
- Level
- Sponges or rags
- Bucket
- New commode bolts and washers (if not included)
Step-by-step
Step 1
Turn off the water supply to the existing commode and flush it completely to empty the tank and bowl.
Step 2
Use a sponge to remove any remaining water from the tank and bowl, then disconnect the water supply line.
Step 3
Unbolt the old commode from the floor. Gently rock it to break the wax seal, then carefully lift and remove it.
Step 4
Thoroughly clean the floor flange, scraping away all old wax, debris, and corrosion to ensure a smooth, level surface.
Step 5
Install new commode bolts into the flange, ensuring they are securely positioned and upright.
Step 6
Place a new wax ring onto the base of the new commode or directly onto the prepared floor flange, ensuring it is centered.
Step 7
Carefully lower the new commode over the bolts, aligning it precisely with the flange. Press down firmly and evenly to compress the wax ring and create a seal.
Step 8
Place washers and nuts onto the commode bolts. Hand-tighten all nuts evenly, then use a wrench to give each a final quarter turn. Do not overtighten.
Step 9
Reconnect the water supply line, ensuring all connections are snug. Turn on the water supply and flush the commode several times, carefully checking for any leaks around the base and connections.
Common mistakes
- Failing to completely shut off the water supply before starting work.
- Reusing an old wax ring, which inevitably leads to leaks.
- Overtightening the mounting bolts, causing cracks in the porcelain.
- Not thoroughly cleaning the floor flange before setting the new commode.
- Incorrectly measuring the ‘rough-in’ distance from the wall to the drainpipe center.
- Forgetting to check for leaks thoroughly and immediately after completing the installation.
When to call a professional
- If the existing floor flange is severely damaged, corroded, or broken and requires replacement.
- You encounter persistent leaks that you cannot resolve despite following all installation steps.
- The commode does not sit level or stable after installation, indicating a potential subfloor or flange issue.
- You discover unexpected plumbing problems such as rusted pipes, blocked drains, or damaged subflooring.
- You lack the necessary specialized tools, experience, or confidence to perform the installation safely and correctly.
