When a toilet keeps leaking, running or rocking on its base, another repair can stop making sense. Two things set what a replacement costs: the toilet you choose and the work needed to fit it. This guide covers both, with the prices plumbers quoted through Service.com.au.
How much does it cost to replace a toilet?
These are the prices plumbers quoted for toilet jobs through Service.com.au in the 12 months to October 2026:
| Job | Typical quote | Most quotes fell between |
|---|---|---|
| Toilet replacement or new toilet installation | $600 | $350 to $900 |
| Toilet leak, cistern or flush repair | $300 | $250 to $400 |
The replacement row combines like-for-like swaps with jobs where the plumber supplies the toilet or fits a different style. Check the inclusions before comparing prices. Supplying your own toilet removes that product from the plumber’s bill, but the connection, access and condition of the existing plumbing still affect the installation cost.
Plumbers quoting to clear a blocked toilet through Service.com.au in the same 12 months had a typical quote of $350, with most quotes between $300 and $450.
Should you repair the toilet or replace it?
Ask a plumber to identify the cause before ordering a new suite. A running cistern or a flush problem may be repairable with replacement parts. A damaged pan, unavailable parts or a planned bathroom redesign can change the decision.
Request a repair option and a replacement option that list what each includes. Compare the diagnosis, parts availability, condition of the suite and the work needed to fit the replacement. The repair and replacement figures above cover different jobs; they are not two prices for fixing the same bathroom.
Have cracked ceramic, recurring leaks or movement assessed. Ask whether the fault is in the toilet or its connection so that replacing the suite does not leave the original problem unresolved.
How much does a new toilet cost?
For the toilet suite alone, allow roughly $150 to $1,000 as a broad product-price guide. Premium suites, frames and concealed-cistern systems can cost more, and installation is separate. Check the exact model and what is included before ordering.
Check the toilet is WELS registered and displays its water rating, and that it has the required WaterMark certification. WELS describes water efficiency; WaterMark checks safety and fitness for purpose. The Australian Government explains both marks and provides product registers. Ask your plumber to check the model before you buy.

If only the bowl (the pan) is cracked, ask your plumber whether a matching replacement pan is available for your cistern. Pans and cisterns are usually sold as a matched suite, so a full replacement is often the simpler job.
How much does it cost to install a new toilet?
Arrange a plumber authorised for the work to connect a new toilet. Many plumbers quote a toilet swap as a fixed price; if yours charges by the hour, ask for an estimate of the total so you can compare it with fixed quotes.
These are the things that move an installation quote up or down:
Same spot or a new one. Swapping a toilet into the existing outlet is the simplest job. Moving the toilet or adding one means new drainage and water pipes.
Changing style. Going from a close-coupled toilet to a back-to-wall suite can mean adjusting the pipework or the water connection.
Wall-hung toilets. These need a frame and cistern built into the wall, so the wall is opened, then sheeted and tiled again. Expect a higher quote and extra trades.
Supply. Some quotes include the toilet, some don't.
Removal and disposal. Taking away the old toilet may be included or charged separately.
Surprises. A cracked floor flange, damaged tiles or old pipework found when the toilet comes out can add to the job.
Tip: Ask every plumber to say whether their quote includes the toilet, removal of the old one and disposal. Then you are comparing the same job.
Check the complete replacement price
Ask each plumber to separate the following items, even if they are bundled into one fixed total. A suite-only retail price and a plumber’s whole-job quote cover different things.
| Item | What to confirm |
|---|---|
| Toilet supply | Exact model, seat, cistern and included fittings; who handles delivery and product issues |
| Removal and fitting | Disconnection, removal of the old suite and installation in the agreed position |
| Connections and adjustments | What existing pipework is reused and what changes are included |
| Disposal | Whether the old suite and packaging will be taken away |
| Other work | Any tiling, wall repairs or floor repairs outside the plumber’s scope |
| Completion | Testing, clean-up and advice on when the toilet can be used |
What are the different types of toilets to choose from?
Most homes choose from four styles. The style you pick affects both the price of the suite and how much work the installation takes.
Close-coupled
The cistern sits directly on the back of the pan, with the flush button on top. It is the most common style and usually the cheapest to buy and install.
Back-to-wall
The pan sits flush against the wall, which hides the pipe connection and makes the floor around it easier to clean. The cistern may sit on top of the pan or be hidden behind a panel.
In-wall cistern
The cistern is concealed inside the wall, with a flush plate on the wall above a floor-standing pan. It saves space and looks tidy, but the cistern is reached through the flush plate opening if it ever needs repair.

Wall-hung
The pan is fixed to the wall and clear of the floor, with the cistern hidden in the wall. It is the most expensive option to buy and to install, because of the frame and wall work it needs.
Check your current toilet outlet
Before you buy a replacement, find out which outlet your current toilet has. A P-trap toilet's waste pipe leaves through the wall behind it. An S-trap toilet's waste pipe goes down through the floor. You can usually tell by looking behind the pan, or ask your plumber.
For an S-trap toilet, the distance from the wall to the centre of the floor outlet (the set-out) also matters. New toilets list the set-out range they fit, so measure it or ask your plumber to before you buy.
Tip: Take a photo of the toilet from the side and the set-out measurement with you when you shop. It is the quickest way to rule out suites that won't fit.
Have the model checked before buying
Outlet type and set-out are part of the fit. Also confirm the water inlet location and the suite’s dimensions with your plumber. Check the manufacturer’s drawing against the bathroom, including the space around the pan and the door’s swing. Caroma’s toilet suite guide explains the outlet, set-out and cistern-inlet choices. Send your plumber the exact model and its technical drawing before ordering.
How long does it take to replace a toilet?
A like-for-like swap into the same outlet is usually done in a single visit. Jobs that change the layout take longer. A wall-hung toilet or an in-wall cistern means opening the wall, fitting a frame and retiling, and moving a toilet means new pipework, so those jobs can run over several days and involve a tiler as well as a plumber.
How to choose the right plumber for your toilet installation?
Use a plumber authorised for the work. NSW requires the appropriate licence or certificate for plumbing, regardless of price. In Victoria, licensed plumbers and registered plumbers working under licensed supervision can carry out plumbing within their authorised class. Queensland also regulates plumbing work. Ask a bathroom renovator who will do the connection, then check that person's credentials with your local regulator.
