How Much Does It Cost to Replumb a Toilet?
One of the most frequently asked questions by homeowners planning a toilet upgrade is about the cost to replumb a toilet. The answer depends on several factors, including the condition of your existing plumbing, the type of toilet you’re installing, and whether any structural changes are required.
Average Toilet Replumbing Cost in Ontario
In Ontario, the cost to replumb a toilet typically ranges from $450 to $1,200 or more, depending on the complexity of the job. This price includes:
- Removal of the old toilet
- Inspection and replacement of the flange, wax ring, and bolts
- Adjusting water supply lines if necessary
- Installation of the new toilet
If your existing drain pipes or water supply lines need to be replaced or rerouted, this can significantly increase the cost. For older homes with outdated plumbing, you might face additional expenses if the plumber needs to bring the system up to current building codes.
Factors Affecting Toilet Replumbing Costs
- Type of Toilet: One-piece, two-piece, wall-hung, or smart toilets vary in price and installation complexity.
- Plumbing Condition: If the existing pipes are corroded, cracked, or improperly sized, they will need to be replaced.
- Location of the Toilet: Relocating a toilet requires new drainage and water lines, which increases costs.
- Disposal Fees: Some plumbing companies charge extra to dispose of the old toilet.
If you’re unsure about the condition of your bathroom plumbing, it’s best to call a professional plumber for an on-site estimate. Delta Plumbers offers free in-home consultations across Ontario to help you budget accurately for your toilet replacement.

Should I Call a Plumber to Replace a Toilet?
While many homeowners consider DIY toilet installation, hiring a licensed plumber is often the smarter choice. Toilet installation may look simple, but many hidden risks could lead to leaks, water damage, or code violations if not done correctly.
Benefits of Hiring a Professional Plumber
- Proper Sealing: Professional plumbers ensure the toilet is correctly sealed to prevent leaks that could damage your flooring and subfloor.
- Flange and Wax Ring Replacement: These parts are crucial to prevent odours and leaks, but are often overlooked in DIY jobs.
- Code Compliance: Licensed plumbers follow Ontario plumbing codes to ensure your installation is safe and legal.
- Correct Alignment: Misaligned toilets can lead to rocking, leaking, and even cracked porcelain.
- Warranty Protection: Many toilet manufacturers require professional installation to maintain warranty coverage.
- Time-Saving: What might take you several hours (or days) can often be done by a professional in under two hours.
DIY Risks
- Improper sealing
- Over-tightening bolts, causing toilet cracks
- Incorrect pipe connections
- Potential water leaks and mold growth
For peace of mind and long-term reliability, always trust an experienced plumber for your toilet replacement service.

Do All Toilets Fit the Same Plumbing?
Not all toilets fit the same plumbing. The rough-in measurement is the distance from the wall to the center of the toilet’s floor drain and is crucial when selecting a new toilet.
Common Rough-In Sizes
- 10 inches
- 12 inches (most common)
- 14 inches
Choosing the wrong size can lead to installation issues or require costly plumbing modifications.
Other Compatibility Considerations
- Bowl Shape: Round or elongated bowls require different space clearances.
- Toilet Height: Standard or comfort height may affect user comfort.
- Water Supply Location: Some toilets require side or rear water connections.
- Mounting Style: Floor-mounted or wall-hung toilets have different installation requirements.
At Delta Plumbers, our experts measure and verify your toilet rough-in and plumbing compatibility to ensure a hassle-free installation.
