How to Remove a Toilet for Repair or Replacement

When you need to remove a toilet

You might need to remove a toilet to fix a recurring leak at the base, replace a cracked bowl or tank, upgrade to a more efficient model, or access the floor for remodeling. A toilet that rocks, a persistent sewage smell, or visible water damage around the base often points to a failed wax ring, which is one of the common reasons for removal. If you are removing the toilet because it leaks, read about toilet wax ring failure signs before you start, so you can confirm the cause while the fixture is off.

Removing a toilet is a straightforward job that most homeowners can do with basic tools. The heavy part of the work is lifting a fragile porcelain fixture without dropping it. A standard two-piece toilet can be awkward to carry because the tank is bolted to the bowl, so it helps to have a second person available to steady the bowl as you lift it off the flange.

If the goal is to replace the toilet with a newer one, decide on the replacement before you begin so you do not leave the bathroom out of service longer than needed. The toilet rough-in sizes article explains how to measure the distance from the wall to the floor bolts, a measurement you will need when choosing the new fixture.

Tools and materials you will need

Before starting, gather the following items: an adjustable wrench or pliers for the supply line nut, a screwdriver for the floor bolt caps, a putty knife or scraper for the wax ring, a sponge and bucket for residual water, a rag or towel to plug the drain opening, and gloves to protect your hands. A small mirror and flashlight help you see the nuts under the bowl base.

You do not need specialty tools to remove a toilet, but a wax ring scraper can make clean-up much easier when you are removing the old sealing material from the flange. If the toilet is caulked around the base, use a utility knife to cut the caulk seam before you try to rock the bowl.

• Adjustable wrench or slip-joint pliers
• Screwdriver (flathead and Phillips)
• Putty knife or plastic scraper
• Sponge and bucket or shallow pan
• Old towels or rags
• Work gloves
• Flashlight and mirror (optional but helpful)

Shut off the water and drain the tank

Locate the shut-off valve on the wall or floor behind the toilet, usually a small oval or round handle on a chrome or plastic supply pipe. Turn the handle clockwise until it stops; if the handle does not move easily, do not force it, you may need to replace the shut-off valve first. Read how to install a toilet shut-off valve for guidance if the valve is stuck or leaking.

Flush the toilet and hold the handle down to let as much water as possible drain from the tank into the bowl. A standard tank will empty on the first flush; the bowl will also drain down to the trap. After the flush, sponge out the remaining water from the tank and bowl. A turkey baster or small cup works well for the bowl trap, and tuck a sponge into the tank opening to soak up the last bit.

You do not need to disconnect the supply line before draining the tank, but the line and valve will hold water under pressure until you turn off the supply. Once the tank is empty, close the shut-off valve fully before disconnecting the supply line from the bottom of the tank. Have a bucket or towel ready to catch the small amount of water that will spill from the line.

A toilet that has not been flushed in a long time may contain stagnant water and possibly debris; wear gloves and eye protection when handling the bowl interior. If the toilet is connected to a septic system, see the toilet septic system compatibility article for general guidance on care, but the removal procedure is no different.

Remove the tank or lift as one piece

If you have a two-piece toilet, you can often remove the tank separately before tackling the bowl. The tank is held to the bowl by two or more bolts that run through the tank and screw into nuts on the underside of the bowl rim. Removing the tank first makes the bowl much lighter and easier to carry. Unthread the bolts with a wrench while holding the nuts with pliers, then lift the tank straight up and set it aside. Be careful: a porcelain tank is heavy and can crack if dropped.

If you prefer to lift the toilet as one unit, or if the tank bolts are corroded and stuck, you can keep the tank attached and lift everything together. This is heavier but avoids loosening old metal bolts that may break. One-piece toilets do not have a separate tank, so the entire fixture comes off the floor as a single unit.

Either way, the final step is the same: rock the bowl gently from side to side to break the wax ring seal. If the toilet is stuck, run a putty knife around the base of the bowl to cut through any old caulk, and try rocking again. Do not use excessive force, a sudden crack can shatter the porcelain.

When the seal breaks, lift the bowl straight up and off the floor bolts. Keep the bowl as level as possible so any water in the trap does not spill onto the floor. Move it to a tub or outside area where you can drain it safely.

Handle the wax ring and flange

Once the toilet is lifted, you will see the wax ring, a round, soft sealing material that sits between the bottom of the bowl and the floor flange. The wax ring may stay on the flange or stick to the toilet horn, either way it must be removed completely before installing a new fixture. Scrape the old wax and any debris off the flange with a putty knife, and remove the old floor bolts if they are rusted or damaged.

Inspect the flange, the plastic or metal ring that connects the toilet to the drain pipe. It should sit flush with the finished floor, have no cracks, and the bolts should be firmly anchored. If the flange is broken, recessed, or not level, it will leak and cause the new toilet to rock. See the toilet flange basics article to understand what a healthy flange looks like, and consult that guide for repair options.

Stuff a rag or old towel into the drain opening before you scrape the old wax, to prevent debris from falling into the pipe and to block sewer gas from entering the bathroom. Remove the rag only when you are ready to install the new wax ring and set the new toilet.

The wax ring creates a watertight seal between the toilet and the flange. If you are reinstalling the same toilet, always use a new wax ring; the old ring will not reseal properly after it has been compressed. Read toilet wax ring vs rubber gasket to decide which type of seal to buy for the reinstall.

Clean up and dispose of the old toilet

With the toilet removed and the drain plugged, use a damp rag to wipe the floor area around the flange, removing any wax residue, grime, or mineral deposits. If the floor is damp, let it dry before installing the new toilet. A dry, clean surface gives the new wax ring a good seal and prevents the toilet from rocking.

To dispose of an old toilet, check with your local waste management service. Many municipalities have special collection days for bulky items, and some recycling centers accept porcelain toilets for crushing and reuse as aggregate. Never place a toilet in a regular trash bin without checking local rules; the porcelain is heavy and can break the bin.

Before you carry the toilet outdoors, drain any remaining water from the trap by tipping the bowl over a bucket or sink. Then wrap it in an old blanket or thick plastic sheathing to protect your floors and the car if you are transporting it. Carry it with the bowl upright or on its side, never upside down, and keep it stable to avoid cracking.

Take this opportunity to clean the floor area thoroughly. If the old toilet was leaking, you may find stains or water damage that need attention. The older home toilet replacement article offers advice on dealing with subfloor issues that are often discovered once the toilet is up.

Before you install the replacement

Once the old toilet is out and the flange is clean and level, you are ready to install the new one. The process is the reverse of removal, but it requires care to set the wax ring correctly and to tighten the floor bolts evenly. Follow the steps in how to install a toilet for a detailed walkthrough, and be sure to use a new wax ring and new floor bolts.

If you have not yet chosen a replacement, review the best 1.28 GPF toilets or the best 1.5 to 1.6 GPF toilets guides to compare models that match your rough-in measurement and flushing preference. Toilets are the largest source of indoor water use in a typical home, and older models that use up to 6 gallons per flush can waste a significant amount of water, as the US EPA notes. Replacing an old fixture with a WaterSense labeled model that uses 1.28 gallons per flush or less can cut toilet water use by 20 to 60 percent for an average family.

If your bathroom has a tiled floor, check the toilet installation on tile floor article for tips on getting a level seal on an uneven surface. For a toilet that rocks, leveling shims may be needed, and you can fix that after installation by following the guidance in how to level a wobbly toilet.

What to pick for your use

Questions

How long does it take to remove a toilet?

Plan for 30 to 60 minutes for the removal itself, plus some extra time to scrape the old wax ring and clean the flange. The first time you do it will take longer because you are learning the process.

Can I remove a toilet without a shut-off valve?

If there is no shut-off valve behind the toilet, you will need to close the main water valve for the house, or the valve for the bathroom zone if one exists. This is a good time to have a plumber install a dedicated shut-off valve, since you will be working in that area anyway.

What do I do if the toilet is stuck to the floor?

Rock the bowl gently side to side to break the wax seal. If it will not move, run a putty knife between the base and the floor to cut any old caulk. If the toilet is still stuck, the floor bolts may be corroded and holding it down, remove the nuts at the base of the bolts first.

Do I need to remove the tank before lifting the bowl?

It is not required, but removing the tank makes the bowl lighter and easier to carry, especially for a two-piece toilet. If the tank bolts are corroded and stuck, it is safer to lift the whole unit together rather than risk breaking the tank.

Can I reuse the wax ring after removing the toilet?

No. A wax ring compresses and deforms to create a seal; once it has been lifted off, it will not reseal properly. Always install a new wax ring when you put the toilet back, even if the old one looks intact.

How do I dispose of an old toilet?

Check with your local waste management service for bulk pickup rules. Some communities offer special collection for porcelain fixtures, and some recycling centers accept toilets. Never place one in a regular trash bin unless your local utility explicitly allows it.
