How Long Does It Take to Replace a Toilet?
Replacing a standard toilet typically takes a professional plumber 1 to 2 hours, including removing the old toilet, replacing the wax ring, and installing the new toilet. DIY installation can take longer, often 2 to 4 hours, especially for first-time homeowners or more complex toilet types like wall-mounted units or two-piece toilets.
Toilet installation involves more than just lifting out the old toilet and setting a new one in place. The process includes shutting off the water supply, disconnecting the supply line, removing the old bolts and wax ring, inspecting the flange for damage, and securing the new toilet with a new wax ring and fresh bolts. While a licensed plumber can usually complete a standard installation in about an hour, factors like rusted bolts, a damaged flange, or upgrading to a more complex toilet can add extra time to the job.
How Long Does a Standard Toilet Installation Take?
A standard toilet installation typically takes about 1 to 2 hours from start to finish, including removing the old toilet and installing the new one. This timeline assumes the existing plumbing lines and flanges are in good condition.
The process usually includes shutting off the water supply, disconnecting the supply line, removing the old toilet, replacing the wax ring, and securing the new toilet in place. A professional plumber familiar with the process can often move quickly through each step, while many homeowners attempting a DIY installation may take longer, working through each stage carefully.
If you are wondering, “Why is my toilet not flushing properly?”, you can always call a professional plumber to fix it.
What Steps Are Involved in Replacing a Toilet?
Replacing a toilet involves removing the old toilet, inspecting the flange, installing a new wax ring, and securing the new toilet bowl and tank before reconnecting the water supply line. Each step needs to be done correctly to prevent leaks.
The typical process looks like this:
- Turn off the water supply and disconnect the supply line
- Flush the toilet to drain the tank and bowl, then use a sponge or bucket to remove remaining water
- Remove the nuts and bolts securing the toilet base to the floor
- Lift the old toilet bowl off the flange and set it aside
- Use a putty knife to scrape away the old wax ring
- Inspect the flange for cracks or damage before continuing
- Install a new wax ring on the flange or the new toilet base
- Lower the new toilet into place, aligning it with the bolts
- Secure the toilet with new nuts, attach the tank if needed, and reconnect the water supply
- Test for drips or leaks around the base and supply line connection
What Factors Can Delay Toilet Replacement?
Toilet replacement can take longer if there are rusted bolts, a damaged flange, a complex toilet type like a wall-mounted unit, or if new flooring needs to be worked around. These issues often require additional tools or repairs before the new toilet can be installed.
Common factors that add time include:
- Rusted bolts that are difficult to remove and may need to be cut with a utility knife or specialized tool
- A damaged flange that requires repair or replacement before installing the new wax ring
- Complex toilet types, such as wall-mounted units or two-piece toilets with additional components
- New flooring was installed around the toilet base, which may require extra care to protect the surface
- Limited access or space makes it harder to maneuver tools and lift the toilet bowl safely
Do You Need a Plumber to Replace a Toilet, or Can You DIY?
Many homeowners choose to replace a toilet themselves to save money, and with the right tools, it’s a manageable project for someone comfortable with basic plumbing tasks. However, a professional plumber is often the better choice for complex toilet types or for damaged flanges.
DIY installation can save on labor costs, but it requires the right tools, a new wax ring, plumber’s tape, and careful attention to the manufacturer’s instructions to avoid leaks. Hiring a licensed plumber may cost more upfront. Still, it can save time and reduce the risk of installation errors, especially for wall-mounted units or when working with rusted bolts or plumbing lines that require extra care.
According to Tommie Haire, a professional plumber with over 30 years of experience, toilet replacement looks simple on the surface, but small details make a big difference. “People often reuse the old wax ring or skip inspecting the flange, and that’s usually where leaks start showing up later,” Haire explains. “Taking the extra few minutes to check the flange and use a new wax ring every time saves a lot of trouble down the road.” That kind of experience-based insight is often what separates a quick installation from one that holds up over time.
What Tools Do You Need to Replace a Toilet?
Replacing a toilet requires basic tools like an adjustable wrench, a putty knife, a new wax ring, plumber’s tape, and a bucket or sponge for any remaining water. Having the right tools on hand before starting helps keep the process moving smoothly.
A typical toolkit includes:
- Adjustable wrench for the bolts and supply line connection
- Putty knife to scrape away the old wax
- New wax ring and bolts for the new toilet
- Plumber’s tape to help seal the supply line connection
- Utility knife for cutting through rusted bolts or old caulk
- A bucket and a sponge to remove remaining water from the tank and bowl
- Gloves to protect hands during removal and cleanup
What Should You Check Before Installing a New Toilet?
Before installing a new toilet, check the flange for cracks or damage, confirm the water supply line and plumbing lines are in good condition, and make sure the new toilet is compatible with the existing rough-in measurement. Skipping these checks can lead to leaks or a poor fit.
It’s also worth reviewing the manufacturer’s instructions for the specific toilet model, as installation steps can vary slightly between standard, two-piece, and wall-mounted toilets. Taking time to inspect the space and existing setup before beginning the installation can prevent surprises partway through the job.
Conclusion
Replacing a toilet is usually a straightforward job that takes a professional plumber about 1 to 2 hours. However, the timeline can stretch out for DIY installations or when dealing with complications such as a damaged flange, rusted bolts, or a more complex toilet type. Taking the time to inspect the flange, use a new wax ring, and follow the manufacturer’s instructions carefully can help ensure the new toilet is secure and leak-free for years to come.
