A toilet installation looks simple, and on a good day it is. The old toilet comes out, the new one goes in and the base is sealed. The cost, however, depends on what is under the old toilet, how the new one fits and what else is worn.
This guide lists the line items so you can judge any quote. We leave out dollar figures because we have no verified local price data to publish, and a made-up range would not help you.
Most toilet installs take a couple of hours. Problems appear when the flange is damaged, the floor is soft or the new toilet does not match the plumbing. Knowing those risks in advance lets you budget for them.
What is in a toilet installation price
| Item | What it covers | Watch for |
|---|---|---|
| The toilet | Bowl, tank and seat, often sold separately | Rough-in size and height |
| Labor | Removal, setting, sealing and testing | Haul-away of the old toilet |
| Wax or foam ring | The seal between toilet and drain | Usually included |
| Supply line and valve | Water connection from the wall | Old valves often need replacing |
| Closet bolts and shims | Hold the toilet level and secure | Included in most installs |
| Flange repair | Fixes a cracked or low flange | Extra if needed |
| Floor repair | Fixes a soft or damaged subfloor | Extra if needed |
The first five items are routine. The last two are the ones that change the price.
Measure the rough-in before you buy
The rough-in is the distance from the finished wall to the center of the drain flange. Most toilets are made for a 12 inch rough-in, but older homes and some bathrooms use 10 or 14 inches. A toilet bought for the wrong rough-in will not fit against the wall. Measure first, and bring the number to the store or tell the plumber.
Height matters too. A comfort-height bowl is a few inches taller than a standard one and is easier on knees and backs. Round or elongated bowl shape affects the space in front, and a small bathroom may only fit a round bowl.

Once the old toilet comes out, the plumber sees what has been hidden:
- A cracked or corroded flange that must be repaired or replaced.
- A flange set too low or too high after a new floor was installed.
- A soft or stained subfloor from years of slow seepage.
- A wax ring that failed, with rot around it.
- Pipe that is cracked or misaligned below the flange.
Most of these are fixable, and a good plumber shows you what is there and explains the cost before continuing. If the subfloor is rotted, the repair may involve a carpenter, and the plumber tells you what is needed.
Repair or replace
A toilet that works but looks tired does not need replacement. Consider repair when the porcelain is sound and the fault is a part such as a flapper or fill valve. Replace when the bowl is cracked, the flush is weak and parts do not help, or the toilet clogs often because of a poor design. Our toilet repair page explains the common faults.
If the toilet clogs repeatedly and other fixtures are slow too, the problem may be the drain, not the toilet. A new toilet will not fix a clogged main line, so check sewer line cleaning first.
Efficiency and flush performance
Newer toilets use less water per flush, and the model matters. A poorly designed low-flow toilet can clog more, and a good one flushes strongly with less water. Look for independent flush performance tests when choosing, and ask the plumber which models they see fewer problems with. A lower water use can show up on your bill over time.

When a running toilet shows up on a water bill
Who to call about the bill in each town
A toilet that runs can raise a water bill, and the right office depends on your town. Lodi's water is supplied by the Passaic Valley Water Commission, whose customer service line is 973-340-4300. Saddle Brook has its own Water Department, reachable at 201-587-2905. Veolia's customer call center for its New Jersey system is 1-800-422-5987, and it applies to Hackensack, Hasbrouck Heights, Maywood and Wood-Ridge according to the state's WaterCheck listings.
Before you call, run the meter test described on our leak detection page to confirm whether the leak is in the house. If you are in Hackensack or Wood-Ridge, confirm your supplier on your bill first, since it is the authority for your address.
Doing it yourself versus hiring
A toilet swap is within reach of a handy homeowner, but there are real risks. A toilet is heavy and breakable. A flange problem or a bad seal can leak slowly and rot the floor. A wrong connection can leak behind the wall.
If you are not sure, a plumber is cheap insurance. If you do it yourself, shut off the water, drain the tank, use a new wax ring and tighten the bolts evenly.
Questions before you book
Ask whether the quote includes the toilet, the supply line, the shutoff valve and removal of the old one. Ask what happens if the flange or floor is damaged. A plumber who explains those cases up front is easier to work with when something unexpected appears.
Toilet cost questions
Does the installer bring the toilet or do I buy it?
Either works. If you buy it, measure the rough-in first. If the plumber supplies it, ask for the model and warranty.
Is a wax ring or a foam ring better?
Both seal well when installed correctly. The plumber picks one based on the flange height and condition.
Will the plumber take the old toilet away?
Ask when you book. Haul-away is usually included, but not always.
How do I know which office handles my water bill if I live near Lodi?
It depends on your town. Lodi uses PVWC, Saddle Brook has its own department and Hackensack-area towns use Veolia. Your bill names your supplier.
Can a toilet leak at the base without showing water?
Yes. A slow leak can rot the subfloor before a puddle appears. A soft floor near the toilet is a warning sign.
Code basis. Plumbing work in New Jersey follows the state plumbing subcode, N.J.A.C. 5:23-3.15, which adopts the 2021 National Standard Plumbing Code. Ask which permits apply to your job and confirm with the Lodi Building Department.
