How to Remove a Toilet: 10 Steps, Tools, Time, and What It Weighs
How to remove a toilet: shut off and drain it, hand-unscrew the 7/8 inch supply nut, remove two floor-bolt nuts, rock the seal loose, and lift a fixture that ships at 82 to 99 lb.
Key Takeaways
- The job runs 10 steps; TOTO’s installation manual lists a 10 inch adjustable wrench, hacksaw, putty knife, and pliers among the common tools.
- TOTO’s spec sheet puts the two-piece Drake at 94 lb shipping weight (62 lb bowl, 32 lb tank), so pulling the tank first cuts the heaviest lift by about a third.
- The tank connection is a 7/8 inch ballcock thread that TOTO says to tighten by hand only, so unscrew it by hand too.
- TOTO’s Drake holds a 2-1/8 inch trap seal after flushing, so plunge it down or wet-vac it before tipping the bowl.
- Kohler’s install guide tells you to plug the open flange with a rag if the new toilet will not go in right away; OSHA notes hydrogen sulfide can deaden your sense of smell at 100 ppm within 2 to 15 minutes.
- Stuck closet bolts get penetrating oil, then a mini hacksaw or oscillating tool; Kohler’s guide calls for new T-bolts anyway.
What tools do you need to remove a toilet, and how long does it take?
To remove a toilet you need a 10 inch adjustable wrench, a flat screwdriver, pliers, a putty knife, and a hacksaw, which is the core of the common-tools list in TOTO’s installation manual. Add a sponge, bucket, plunger, rags, gloves, and penetrating oil. By our estimates, a clean job takes 45 to 60 minutes across 10 steps.
If the closet-bolt nuts are green or rusty, add an oscillating multi-tool with a metal-cutting blade or a mini hacksaw.
Buy reinstall parts first. TOTO’s manual lists a wax ring, closet bolts (usually 2 T-bolts, 2 metal washers, 2 nuts), and a supply line.
| Step | Tool | Typical time (editorial estimate) |
|---|---|---|
| 1. Close the shutoff valve | Hand (clockwise) | 1 min |
| 2. Flush, hold handle, sponge tank | Sponge, bucket | 5 min |
| 3. Plunge or wet-vac the bowl and trap | Flange plunger or shop vac | 5 min |
| 4. Unscrew supply line at the tank | Hand, pliers if stuck | 2 min |
| 5. Remove tank (optional, two-piece) | Flat screwdriver, 10 in adjustable wrench | 10 min |
| 6. Pop bolt caps, remove floor nuts | Flat screwdriver, 10 in adjustable wrench | 5 min (add 15 to 30 if stuck) |
| 7. Cut caulk line, rock the seal loose | Utility knife, hands | 3 min |
| 8. Lift and carry the toilet out | Gloves, cardboard or old towel | 3 min |
| 9. Plug the flange with a rag | Large rag, bucket | 1 min |
| 10. Scrape old wax, inspect flange and subfloor | Putty knife, flashlight | 10 min |
How do you shut off and drain a toilet before you remove it?
Turn the shutoff valve behind the toilet clockwise until it stops, then flush and hold the handle down so the tank drains all the way. Sponge the last inch out of the tank into a bucket. Then empty the bowl, because a flush leaves the trap full and it spills when you tip the toilet.
If the valve weeps or will not close, shut the house main; our guide on how to shut off the water shows where. TOTO specifies 20 to 80 psi static supply pressure, so a half-closed valve will soak the floor.
The trap is the hidden reservoir. TOTO’s Drake spec sheet lists a 2-1/8 inch trap seal, the standing water that blocks sewer gas. Two ways to empty it:
- Plunge it down. Give the bowl a few firm strokes with a flange plunger to push the water past the trap into the drain line.
- Vacuum it out. Run a wet/dry shop vac hose to the bottom of the bowl until it sucks air, which clears the trap too.
How do you disconnect the toilet supply line?
Unscrew the coupling nut where the supply line meets the fill valve, usually under the left side of the tank, turning it counterclockwise by hand. TOTO’s manual says this 7/8 inch ballcock thread should be tightened finger tight only and warns that a wrench can damage the plastic threads, so it rarely needs more than hand force or gentle pliers to come off.
Hold a towel under the nut. If mineral scale has frozen it, use slip-joint pliers, not a pipe wrench.
TOTO lists the typical line as 1/2 inch compression to 7/8 inch ballcock; check your valve outlet before buying a new one, and replace any kinked or bulging braided line now.
How do you remove toilet bolts that are stuck or corroded?
Pry off the two plastic bolt caps with a flat screwdriver, then turn each closet-bolt nut counterclockwise with a 10 inch adjustable wrench. If a nut is seized, soak it with penetrating oil. If the bolt spins, grip the bolt. If neither works, cut it, since closet bolts get replaced on every reinstall.
TOTO’s parts list shows a metal bolt, washer, and nut under plastic caps on each side, and metal corrodes in a damp bathroom.
The stuck-nut sequence, in order
- Penetrating oil. Soak the threads with PB Blaster or WD-40 Specialist Penetrant and let it work while you drain the tank or remove it.
- Stop the spin. Clamp locking pliers on the bolt threads above the nut, or push the bolt down into the flange slot with a screwdriver tip while you turn the nut.
- Oscillating tool. Fit a bi-metal metal-cutting blade and slice through the bolt between the nut and the porcelain. Lay painter’s tape or a putty knife against the china to protect the glaze.
- Mini hacksaw. A hacksaw is on TOTO’s tool list; a close-quarters mini hacksaw or a bare blade wrapped in tape reaches where a full frame cannot.
- Nut splitter. It cracks a rusted hex nut without touching the porcelain.
Skip the reciprocating saw; one slip chips the glaze. Kohler’s installation guide starts with removing the old toilet, T-bolts, and wax ring, so a cut bolt is never a loss.
How do you remove a toilet tank from the bowl?
To remove a toilet tank, drain it fully, disconnect the supply line, then hold each tank-bolt head inside the tank with a flat screwdriver while you turn the nut underneath the bowl ledge with a wrench. TOTO’s two-piece manual uses two brass tank bolts and sets their nuts finger tight plus 1/2 turn, so they rarely fight back unless corroded.
Lift the tank straight up and set it on a towel. If you reinstall it, replace the tank-to-bowl gasket and bolt washers.
The payoff is weight. TOTO lists the Drake tank at 32 lb, so pulling it drops the heaviest lift from 94 lb to 62 lb. Rusted tank bolts get the same treatment as floor bolts: penetrating oil, then a hacksaw blade slid into the gap between tank and bowl.
How do you break the wax seal and lift a toilet off the floor?
Run a utility knife around any caulk line at the base, then straddle the bowl, grip the rim, and rock it gently side to side and front to back until you feel the wax seal let go. Lift straight up so the bowl clears the bolts, keep it level until the trap is over a towel, then carry it with your legs, not your back.
Maker spec sheets list shipping weights (box included), so the bare china weighs a bit less. A one-piece toilet is a two-person carry.
| Toilet (model) | Type | Bowl | Tank | Heaviest single lift |
|---|---|---|---|---|
| TOTO UltraMax II (MS604114CEFG) | One-piece | 99 lb together | 99 lb | |
| TOTO Drake (CST776CEFG) | Two-piece | 62 lb (C776CEFG) | 32 lb (ST776EA) | 62 lb with tank off |
| TOTO Drake II (CST454CEFG) | Two-piece | 57.3 lb (C454CUFG bowl) | 31.5 lb (ST454E tank) | 57.3 lb with tank off |
| Gerber Viper (GVP21518) | Two-piece | 52 lb (GVP21528) | 30.1 lb (GVP28590) | 52 lb with tank off |

Set the toilet on cardboard or an old towel so the last trap water drains into it.
What should you do with the open drain after you remove a toilet?
Stuff a large rag into the flange opening right away, big enough that it cannot drop into the pipe, and leave a corner sticking out. Kohler’s installation guide tells installers to plug the waste flange with a rag whenever the new toilet will not go in immediately. The rag blocks sewer gas and keeps tools and wax out of the pipe.
Your nose is a poor alarm here. The OSHA hydrogen sulfide hazards page puts the rotten-egg odor threshold at 0.01 to 1.5 ppm, notes that prolonged exposure at 2 to 5 ppm may cause nausea and headaches, and says 100 ppm causes loss of smell after 2 to 15 minutes.
For a longer gap, cover the plugged flange with an upside-down bucket. Scrape the old wax off with a putty knife into a bag, not down the pipe, and read why a toilet wax ring is single-use before you buy the new one.
What should you check on the flange and subfloor after you remove a toilet?
With the toilet out, check four things before anything new goes down: the flange for cracks and broken bolt slots, the flange screws for a solid bite in the floor, the flange height against the finished floor, and the subfloor around it for soft or dark wood. Then measure the rough-in from the finished wall to the center of the flange so the new toilet fits.
- Cracked or broken flange. A broken bolt slot or a cracked rim usually takes a screw-down repair ring rather than a full replacement; our guide to toilet flange types, height, and repair rings walks through both.
- Loose flange. A flange that moves lets the new toilet rock; re-screw it into solid wood.
- Soft subfloor. Probe with a screwdriver tip. Wood that dents, crumbles, or shows black staining means a long-running leak; patch it first.
- Rough-in. TOTO’s manual says the wall-to-flange distance must be at least 12 inches for most of its models, with 10 and 14 inch versions carrying a .10 or .14 suffix. American Standard’s Champion 4 spec sheet also calls for a 12 inch minimum.
Call a licensed plumber if a cast iron drain under the flange is cracked, and a carpenter if rot spreads past the flange area.
What do you do next after removing a toilet?
Next, either reinstall or haul away. To put a toilet back, pull the rag, set new closet bolts and a new wax ring, lower the bowl straight down, and tighten the nuts evenly. To dispose of the old one, check your city’s bulky-item or recycling rules, since many haulers treat porcelain as bulky or construction debris and rules vary by city.
Our guide on how to install a toilet covers setting and leveling. TOTO says to tighten floor nuts evenly until the bowl is snug and warns that over-tightening can damage the china, and its manual sets tank bolts so the tank makes three points of contact with the bowl.
Turn the water on slowly and flush several times, watching the base, tank bolts, and supply nut.
How we sourced this
We mapped the top-ranking removal guides (Roto-Rooter, The Home Depot, 1-800-GOT-JUNK) in October 2026, then checked every specification against primary documents: TOTO spec sheets SS-02049 (Drake), SS-00239 (Drake II), and SS-00162 (UltraMax II), TOTO installation manual 0GU048Z, Kohler installation guide 1145310-2, the Gerber Viper spec sheet, the American Standard Champion 4 spec sheet (3186528ST), and OSHA’s hydrogen sulfide hazards page. Weights are maker-listed shipping weights. We excluded retailer-listed weights we could not match to a maker document. Step times are editorial estimates.
Frequently asked questions
How long does it take to remove a toilet?
By our step estimates, a toilet with a working shutoff valve and clean brass bolts comes out in roughly 45 to 60 minutes, including draining, unbolting, lifting, and scraping the flange. Corroded closet bolts that need penetrating oil or cutting add about 15 to 30 minutes. Removing a two-piece tank first adds about 10 minutes but cuts the heaviest lift by roughly a third.
Can one person remove a toilet alone?
Yes, if you split the job. TOTO’s spec sheet lists the Drake bowl at 62 lb and its tank at 32 lb as shipping weights, so taking the tank off first leaves two manageable lifts. A one-piece toilet such as TOTO’s UltraMax II ships at 99 lb in one awkward piece, and that lift is easier and safer with a second person.
How do you get all the water out of a toilet before removing it?
Close the shutoff valve, then flush and hold the handle down so the tank empties completely. Sponge the last inch out of the tank. In the bowl, plunge firmly a few times to push most of the water down past the trap, then sponge or wet-vac what remains. A wet/dry shop vacuum is the fastest way to empty both the bowl and the trap.
What do you put in the toilet drain after removing the toilet?
Stuff a rag into the flange opening, large enough that it cannot drop into the pipe, and leave a tail sticking out so you remember to pull it. Kohler’s installation guide tells installers to plug the waste flange with a rag whenever the new toilet will not go in right away. Setting an upside-down bucket over the opening adds a second barrier.
Can you reuse the wax ring when you put the toilet back?
No. A wax ring compresses into the shape of the flange and toilet horn the first time the bowl is set, and once the seal is broken by rocking it free, it cannot reseal reliably. Kohler’s guide calls for removing the old T-bolts and wax ring and installing a new ring. A new wax ring costs only a few dollars.
How much does a toilet weigh?
The maker spec sheets we checked list complete toilets at 82 to 99 lb including packaging. TOTO lists the one-piece UltraMax II at 99 lb shipping weight and the two-piece Drake at 94 lb (62 lb bowl plus 32 lb tank). Gerber lists its Viper bowl at 52 lb and tank at 30.1 lb. The bare china weighs somewhat less than the boxed figure.
