Replacing a toilet is usually a straightforward plumbing project, but the final bill can vary significantly depending on the toilet you choose and the condition of the plumbing beneath the existing fixture.
For a standard replacement in the United States, most homeowners should budget approximately $300 to $600 for the toilet, materials, and professional installation. National cost data places the average near $374, with many installations falling between $224 and $533. A basic project can cost less, while one-piece, wall-mounted, bidet, and smart toilets can raise the total to $1,000 or considerably more.
The lowest prices generally apply when the new toilet fits the existing drain location, the shutoff valve works properly, and the flange and bathroom floor are in good condition. Costs rise when the plumber discovers corrosion, water damage, an incorrect rough-in measurement, or a broken toilet flange.

Average Cost to Replace a Toilet
A typical like-for-like toilet replacement costs between $300 and $600, including the fixture and professional labor.
A like-for-like replacement means:
- The new toilet uses the existing drain location
- The rough-in measurement is compatible
- The water supply line is nearby
- The floor flange is undamaged
- No electrical outlet is needed
- The bathroom floor does not require repair
National installation estimates vary because some companies include the toilet, wax ring, supply line, and removal in the advertised price, while others quote labor separately.
Current cost guides report an average installation price of approximately $374, with a common range of $224 to $533. Another national estimate places standard toilet replacement at $300 to $600, including labor and materials.
Before accepting an estimate, ask exactly what it includes. A low installation quote may not cover delivery, removal, disposal, a new toilet seat, or repairs discovered after the old toilet is lifted.
Toilet Replacement Cost Breakdown
The main expenses are the toilet itself, installation labor, small plumbing materials, and removal of the old fixture.
| Expense | Typical share of project |
|---|---|
| New toilet | $100–$1,500+ |
| Installation labor | $185–$400 |
| Wax seal, bolts, supply line, and caulk | $20–$75 |
| Old toilet removal and disposal | $50–$200 |
| Additional plumbing or floor repairs | Varies |
For a straightforward replacement, the toilet and labor usually represent most of the final price.
How Much Does a New Toilet Cost?
New toilet prices commonly range from approximately $90 to $1,500, with many standard residential models costing between $150 and $500. Premium bidet and smart toilets may cost $1,000 to $3,000 or more.
Two-piece toilet
A two-piece toilet has a separate tank and bowl. It is the most common and generally the most affordable option.
A basic two-piece model usually costs around $100 to $300, although upgraded designs with stronger flushing systems, comfort-height bowls, or premium finishes can cost more.
Two-piece toilets are easier to carry because the tank and bowl can be moved separately. Replacement parts are also widely available.
One-piece toilet
A one-piece toilet combines the tank and bowl into a single fixture. These toilets have a cleaner appearance and fewer exterior seams, but they are heavier and generally more expensive.
A one-piece installation can average significantly more than a basic two-piece replacement. Current cost estimates place a typical two-piece installation near $375 and a one-piece installation closer to $800, depending on the model and labor required.
Dual-flush toilet
Dual-flush toilets provide separate flush settings for liquid and solid waste. Prices vary depending on whether the toilet is a basic two-piece design or a premium one-piece model.
A standard dual-flush toilet may cost between $200 and $600, while designer models can exceed that range.
Pressure-assisted toilet
Pressure-assisted toilets use compressed air to create a powerful flush. They can be useful in high-traffic homes or properties that frequently experience clogs, but they are usually louder and more expensive than standard gravity-flush models.
The fixture and installation can cost $500 to $1,000 or more, depending on the brand and design.
Bidet or smart toilet
Smart toilets may include:
- Heated seats
- Integrated bidet washing
- Warm-air drying
- Automatic flushing
- Motion-activated lids
- Night lights
- Deodorizing systems
- Remote controls
The toilet alone may cost $1,000 to $3,000 or more. Installation can also require a nearby GFCI-protected electrical outlet, increasing the total if an electrician is needed.
Wall-mounted toilet
Wall-mounted toilets use a concealed tank and carrier installed inside the wall. They create a modern appearance and make the bathroom floor easier to clean, but installation is much more involved than replacing a floor-mounted toilet.
A complete wall-mounted installation can cost approximately $1,500 to $4,000 or more because it may require wall framing, plumbing relocation, drywall, waterproofing, and tile repair.
Labor Cost to Replace a Toilet
Professional labor for a standard toilet installation generally costs $185 to $400, according to current installation pricing. A very simple replacement may cost closer to $100 to $150 in lower-cost markets, while complicated installations can cost substantially more.
A standard labor charge normally covers:
- Turning off and disconnecting the water supply
- Draining and removing the old toilet
- Cleaning the existing flange
- Installing a new wax ring or seal
- Positioning and securing the new toilet
- Connecting the tank and supply line
- Testing for leaks
- Applying caulk around the base when appropriate
A straightforward replacement usually takes a professional approximately one to three hours. Travel charges, minimum service fees, and disposal may be billed separately.
Labor rates are generally higher in major cities and high-cost metropolitan areas. Weekend, evening, and emergency appointments can also increase the price.
Toilet Installation Materials Cost
Small installation materials are inexpensive compared with the toilet and labor, but they are essential for preventing leaks.
Wax ring or toilet seal
The wax ring creates a watertight seal between the toilet outlet and the floor flange.
Wax rings and wax-free seals typically cost between $2 and $44, with many standard products priced near $10.
A new seal should be used whenever a toilet is removed. Reusing the old wax ring can result in wastewater leaks and damage to the floor.
Water supply line
A flexible toilet supply line generally costs around $10 to $30. Replacing an older line during installation is usually inexpensive and can reduce the risk of future leaks.
Some professional installation packages include the supply line, while others charge separately.
Toilet bolts and mounting hardware
New closet bolts, washers, caps, and mounting hardware usually cost $5 to $20. Some toilets include these components, but not every model does.
Toilet seat
A basic toilet seat may cost $20 to $50, while soft-close, heated, bidet, or premium seats can cost $50 to several hundred dollars.
Do not assume the seat is included with the toilet. Check the product description before calculating your materials budget.
Caulk and shims
Plumbers may use plastic shims to stabilize the toilet on an uneven floor and bathroom-rated caulk to seal the base. These materials usually add less than $20 to the project.
Additional Costs That Can Increase the Price
The largest cost increases usually appear after the old toilet is removed and the plumber can inspect the flange, drain opening, and surrounding floor.
Old toilet removal and disposal
Removing and disposing of the existing toilet commonly costs $50 to $200. Some installation companies include this service in the labor quote, while others treat it as an add-on.
You may be able to save money by arranging disposal yourself, but toilets are heavy and may require special handling under local waste rules.
Toilet flange replacement
The flange connects the toilet to the drainpipe and anchors it to the floor. A cracked, rusted, loose, or improperly positioned flange can cause the toilet to wobble or leak.
A straightforward flange replacement commonly costs around $145 to $165, although more involved repairs may cost $350 or more. Extensive water damage can raise the price substantially.
Shutoff valve replacement
If the toilet shutoff valve is corroded, leaking, or unable to stop the water completely, the plumber may recommend replacement.
A new valve can add approximately $100 to $250, depending on pipe access, local labor rates, and whether the pipe requires modification.
Floor or subfloor repair
A toilet that has leaked around the base may damage flooring and subflooring. Repair costs depend on how far the moisture has spread and the type of flooring installed.
Minor damage may add a few hundred dollars. Extensive rot, mold remediation, tile replacement, or structural repairs can raise the project by $1,000 or more.
Drain repairs
If the plumber discovers a clogged, cracked, or incorrectly positioned drain, the toilet cannot simply be installed over the problem.
Drain cleaning, pipe replacement, or relocating the waste line will be quoted separately.
Changing the toilet location
Moving a toilet is much more expensive than replacing one in the same location because the drain, vent, and water line may need to be relocated.
Depending on the bathroom layout and access beneath the floor, relocation can add hundreds or thousands of dollars.
Choosing the Correct Replacement Toilet
Buying the wrong toilet can result in added labor, returns, or plumbing modifications.
Measure the rough-in
The rough-in is the distance from the finished wall—not the baseboard—to the center of the toilet’s floor bolts or drain outlet.
The most common residential rough-in is 12 inches, but some bathrooms require a 10-inch or 14-inch model.
Check bowl shape
Elongated bowls are generally more comfortable but extend farther into the bathroom. Round bowls save space and may fit better in small bathrooms.
Measure the available distance between the toilet and nearby doors, cabinets, or walls.
Choose the right seat height
Standard-height toilets are usually comfortable for children and shorter users. Chair-height models can make sitting and standing easier for taller adults and people with mobility limitations.
ADA-accessible toilet seats must generally measure 17 to 19 inches above the finished floor in facilities subject to accessibility standards.
Consider water efficiency
EPA WaterSense-labeled toilets use 1.28 gallons per flush or less, which is at least 20% less water than the federal standard of 1.6 gallons per flush. WaterSense toilets are independently certified for both efficiency and flushing performance.
Some local water utilities offer rebates for replacing older toilets with qualifying WaterSense models. Check your utility’s website before purchasing.
Repair or Replace the Toilet?
Replacement is usually the better choice when:
- The porcelain bowl or tank is cracked
- The toilet leaks repeatedly
- The base continues to wobble
- Repairs are becoming frequent
- The toilet clogs regularly
- Replacement parts are unavailable
- The fixture uses excessive water
- You want a different height or bowl shape
A repair may be more economical when the problem is limited to the fill valve, flapper, handle, supply line, or wax ring.
The average toilet repair costs around $271, with many repairs ranging from $150 to $391. When the repair estimate approaches the price of a new standard toilet, replacement may provide better long-term value.
Can You Replace a Toilet Yourself?
An experienced homeowner can replace a standard floor-mounted toilet and save on labor. A DIY project may cost only the price of the fixture and basic materials.
However, toilets are heavy, and an incorrect installation can cause:
- Wastewater leaks
- Floor damage
- A rocking or unstable base
- Cracked porcelain
- Loose water connections
- Sewer gas odors
- Hidden subfloor damage
Professional installation is the safer choice when the flange is damaged, the shutoff valve does not work, the toilet is unusually heavy, or the new model requires plumbing or electrical modifications.
How to Save Money on Toilet Replacement
- Choose a compatible toilet. Matching the existing rough-in and footprint reduces labor.
- Buy a complete installation kit. Confirm whether the toilet includes a seat, wax ring, bolts, and supply line.
- Schedule regular weekday service. Avoid emergency and after-hours rates.
- Ask about removal fees. Disposal may not be included in the advertised price.
- Inspect for leaks early. Addressing a loose or leaking toilet can prevent expensive floor damage.
- Compare written estimates. Confirm that each quote includes labor, materials, removal, disposal, and warranty coverage.
- Check for rebates. Local utilities may offer incentives for WaterSense-certified toilets.
- Avoid unnecessary relocation. Keeping the toilet in the same position is significantly less expensive.
Frequently Asked Questions
How much does it cost to replace a toilet, including labor?
A standard professional replacement usually costs $300 to $600, including the toilet, basic materials, and labor. National averages place many installations between $224 and $533.
How much does a plumber charge to install a toilet?
Professional labor commonly costs $185 to $400 for a straightforward installation. Complicated plumbing, flange repairs, and difficult access increase the price.
Does toilet installation include the toilet?
Not always. Some quotes include only labor, while others include the toilet, wax ring, supply line, removal, and disposal. Request an itemized estimate before scheduling the work.
How long does it take to replace a toilet?
A standard like-for-like replacement usually takes one to three hours. Flange damage, floor repairs, plumbing modifications, or wall-mounted systems require more time.
Do you need a new wax ring when replacing a toilet?
Yes. A new wax ring or wax-free seal should be installed whenever the toilet is removed. The seal prevents wastewater and sewer gas from escaping around the base.
