Toilet Replacement in Sydney: 2026 Costs and Step-by-Step
The short answer. In Sydney, Sydney Water WaterFix charges $400 to $1,100 for a like-for-like toilet replacement package (old toilet removed, new standard suite supplied and installed), plus a $44 callout fee. The Quote Yard's NSW guide lists $300 to $600 for a like-for-like swap, labour only, or $600 to $1,200 to supply and install a standard close-coupled suite. These are other providers' prices, not ours. Replacing a toilet with a smart toilet costs more because it needs a power point as well as water.
LORENTIS prices. A LORENTIS K31 or K4 ($2,690) + LORENTIS install from $990* + LORENTIS removal of your old toilet ($300) comes to from $3,980*. A LORENTIS power point is +$1,100 if you need one.
Toilet replacement usually starts with one of three things: a crack, a leak, or the slow realisation that the toilet has been the same shade of beige since the house was built. The first two are urgent. The third has been urgent for about twenty years.
Right. Straight face now.
This guide covers what toilet replacement costs in Sydney, what to check before you buy, how the job runs on the day, and what it costs to replace your old toilet with one of our smart toilets. Every figure names its source and says exactly what it covers.

What toilet replacement costs in Sydney
Published prices for toilet replacement in Sydney cover very different things. Some include the new toilet, some are labour only, and some leave out removing the old one. Check the scope of each figure before you compare it with a quote.
Sydney Water WaterFix
Sydney Water's fixed-price WaterFix Residential service publishes its charges in a schedule of services and charges (July 2026) (opens in a new tab):
| WaterFix charge (incl GST) | What it covers | Price |
|---|---|---|
| Toilet replacement packages | Remove and dispose of the old toilet, then supply and install a new dual flush suite (pan and cistern). The new suite must be the same type as the old one. | Sydney Water WaterFix charges $400 to $1,100, depending on the suite, plus the callout fee |
| Standard model 2 toilet replacement | The same package with a standard dual flush suite with a hidden trap | $440, plus the callout fee |
| Callout fee | Callout fee only, charged for the first visit even if no work is done | $44 |
| Hourly labour charge | Labour only, per hour | $99 |
The schedule lists lower package prices where the old toilet is single flush and only the toilet is replaced.
Private plumbers in NSW
The Quote Yard (opens in a new tab) publishes indicative NSW figures:
| Job (NSW) | What it covers | Typical cost |
|---|---|---|
| Like-for-like swap | Labour only. You supply the toilet. | The Quote Yard lists $300 to $600 |
| Close-coupled toilet | Supply and install | The Quote Yard lists $600 to $1,200 |
| Smart toilet or bidet seat | Installed. The source says it needs a power point, but doesn't say whether the toilet or the power point is included. | $2,000 to $5,000 |
| Moving the toilet to a new position | Relocating the toilet. The source gives a range only. | $2,500 to $6,000 or more |
| Removal and disposal of the old suite | Removal and disposal only, where it isn't already in the quote | $50 to $150 |
These are other businesses' figures, not ours.
Retail and national guides
- Bunnings lists its toilet installation service from $299, excluding NSW (opens in a new tab). That is an install service for a toilet you buy from Bunnings, for like-for-like replacements in the same spot only. In NSW, Bunnings connects you to an installer through hipages for a quote instead, so the $299 figure doesn't apply in Sydney.
- What's The Damage puts a like-for-like replacement, supply and install, at $400 to $900 nationally (opens in a new tab). Its scope is disconnecting and disposing of the old suite and fitting a standard close-coupled suite to the same water and waste connections.
The pattern is the same everywhere. A like-for-like swap in the same spot costs the least. Moving the toilet, changing its type or adding power puts you in a different bracket.
Repair or replace?
Not every faulty toilet needs replacing. A running cistern or a slow refill is often one worn part inside the cistern. These signs point the other way:
- A crack in the pan or cistern. Cracked ceramic can't be repaired properly.
- A leak at the base that keeps coming back. The seal to the waste is failing, and water may be reaching the floor underneath.
- Repeat repairs. When the second or third part fails on an ageing suite, the money starts adding up to a new toilet.
- Parts you can't get. Some older or imported toilets no longer have spare parts available.
- You want a different toilet. A renovation, an easier-to-clean shape or a smart toilet is a fair reason on its own.
If you're not sure, ask the plumber to price both the repair and the replacement on the same visit.
What to check before replacing a toilet
Most surprises on replacement day come from a new toilet that doesn't suit the old connections. Check these before you buy.
The trap type
The trap is where the toilet connects to the waste pipe. An S-trap goes into the floor and a P-trap goes into the wall. Your new toilet needs to suit the same trap type, or the plumbing has to change.
The set-out
The set-out is the distance from the finished wall (not the skirting) to the centre of the waste pipe. You can measure it with the old toilet still in place, to the bolts that hold the pan to the floor. If the new toilet's set-out doesn't match, the plumber may need an offset connector or extra pipework.
The water outlet
The water outlet is the stop tap that feeds the toilet. Note whether it sits beside the toilet or behind it, and how high it is. For a smart toilet, this decides a lot about the install.
The space
Measure the room around the toilet, including the door swing. A larger or smaller pan can also leave gaps or marks in the tiles where the old one sat.
Power
A standard toilet doesn't need power. A smart toilet needs a power point close by. If there isn't one, it has to be added by an electrician before the toilet can work.
Replacing a toilet, step by step
A like-for-like replacement follows the same steps whoever does it:
- Turn off the water. The plumber shuts the stop tap and empties the cistern.
- Remove the old toilet. The pan is unbolted from the floor and lifted out. This is when hidden problems show up, such as a rotted floor or a cracked waste connection.
- Check the connections. The plumber checks the waste, the set-out and the stop tap against the new toilet.
- Fit the new toilet. The pan is connected to the waste and fixed in place, and the water is connected with a flexible hose to the stop tap.
- Test it. The plumber checks the flush, the refill and every seal for leaks.
- Paperwork. In NSW the plumber handles the required notices for the work. The NSW Government's plumbing inspection documents page (opens in a new tab) explains the Notice of Work and when an inspection is needed.
The Quote Yard puts a like-for-like swap at 1 to 2 hours and a close-coupled suite at 2 to 3 hours. Replacing a toilet with a smart toilet takes longer, because there are two trades involved (more on that below).
Choosing a plumber for toilet replacement
Toilet replacement isn't a DIY job in NSW. The NSW Government's guide to checking your contractor or tradesperson (opens in a new tab) says a licence is needed for all specialist work, whatever it costs, and that specialist work includes plumbing, drainage and electrical wiring.
When you compare plumbers to replace a toilet:
- Check the licence. You can look it up through NSW Fair Trading before you book.
- Ask for a written, itemised quote. It should show the toilet (if they supply it), labour, removal and disposal, parts and any callout fee as separate lines.
- Ask how surprises are priced. Agree up front what happens if the floor or the waste connection turns out to be damaged.
- Book business hours. A toilet replacement is rarely an emergency, and after-hours rates cost more. WaterFix, for example, adds a $55 surcharge from 6pm on weekdays.
Replacing a toilet with a smart toilet
A smart toilet uses the same water and waste connections as any toilet, so the plumbing side of the job looks familiar. Two things are different.
- It needs power. Most Sydney bathrooms don't have a power point beside the toilet, so an electrician usually has to add one.
- There are two trades. You need a plumber for the toilet and an electrician for the power point. Finding, booking and lining up both is often the hardest part of the job.
That's the gap we fill. We sell the smart toilet and arrange the licensed plumber, and the electrician too if you need a power point. Every one of our five models has a self-opening lid and flushes on its own.
What it costs with LORENTIS
All prices include GST.
The toilet
The install
- Licensed plumber install: from $990* in Sydney metro, for all five models. This applies where the water outlet is beside the toilet. Our plumbers are licensed and give you a certificate of installation when the job is done.
- LORENTIS removal of your old toilet: +$300.
- LORENTIS power point near the toilet: +$1,100, a fixed price across Sydney metro. Every model needs one. You can book it on its own.
- Water outlet behind the toilet? Send us a photo and we'll tell you what's needed.
Allow 1 day for the electrical work and 1 day for the plumbing.
Replacement totals by model
Each total is a LORENTIS toilet + LORENTIS install from $990* + LORENTIS removal of your old toilet ($300). The second column adds a LORENTIS power point ($1,100).
| Model | Toilet, install and removal | With a power point |
|---|---|---|
| K31 or K4 | from $3,980* | from $5,080* |
| K1 | from $4,280* | from $5,380* |
| K68 | from $4,480* | from $5,580* |
| K73 | from $4,980* | from $6,080* |
Two ways to buy
The toilet price covers the toilet only.
- For peace of mind, start with a free assessment. Send us photos of your bathroom. We check that our smart toilets suit it and confirm the install method and price, including removal and a power point if you need them. If it suits your bathroom, you buy your toilet. Once it arrives, you book the install. You pay for the install when you book it, after your free assessment.
- If you have your own plumber, just buy now. Choose your model from the collection and order it, and your plumber installs it.
Our photo guide shows what to take: the toilet from the doorway, a side view showing the wall behind, the water outlet up close, the nearest power point (or the wall where one could go) and the floor.
Cost to replace a toilet: three examples
Each example covers the same scope: a new toilet, installing it and taking out the old one.
- A standard toilet through Sydney Water's WaterFix. The standard model 2 replacement package is $440 including GST. It covers removing and disposing of the old toilet and supplying and installing a standard dual flush suite. Add the $44 callout fee: $440 + $44 = $484.
- A close-coupled toilet through a private plumber. The Quote Yard's NSW guide lists $600 to $1,200 to supply and install. If removal and disposal isn't in the quote, The Quote Yard's guide adds $50 to $150: $650 to $1,350.
- A LORENTIS smart toilet. A LORENTIS K31 or K4 ($2,690) + LORENTIS install from $990* + LORENTIS removal of your old toilet ($300) = from $3,980*. With a LORENTIS power point, add $1,100: from $5,080*.
A smart toilet costs more than a standard suite, and we'd rather say so plainly. What you get for the difference is the toilet itself, and one team arranging the plumber and the electrician. For more on install prices alone, see our guide to toilet installation cost in Sydney.
When a smart toilet isn't right for you
We'd rather tell you now than after you've paid.
- You just need a working toilet. If the old one has failed and you only want a reliable replacement, a standard suite through WaterFix or a local plumber costs far less.
- You want a wall-hung toilet. Our five models are one-piece smart toilets, not wall-hung toilets with an in-wall cistern.
- You're renting. Replacing the toilet and adding a power point needs the owner's say-so. Ask your landlord first.
- You live outside Sydney metro. Our install service covers Sydney metro. Ask us if you're further out, but a local plumber may suit you better.
- You're moving the toilet. Our from $990* price doesn't cover moving drainage. Talk to a plumber about that first.
Questions to ask before you buy or install
- Is my trap an S-trap (floor) or a P-trap (wall), and does the new toilet suit it?
- What is my set-out, and does the new toilet match it?
- Is my water outlet beside the toilet or behind it?
- Is there a power point within reach of the toilet, and if not, who adds one and what does it cost?
- Does the quote include removal of the old toilet, parts and any callout fee, as separate lines?
- Is the plumber licensed in NSW, and what paperwork will I get when the job is done?
FAQ

Sydney Water WaterFix charges $400 to $1,100 for its toilet replacement packages, which cover removing and disposing of the old toilet and supplying and installing a new dual flush suite of the same type, plus a $44 callout fee. The Quote Yard's NSW guide lists $600 to $1,200 to supply and install a standard close-coupled suite. LORENTIS prices are separate: a LORENTIS K31 or K4 at $2,690 plus LORENTIS install from $990* plus LORENTIS removal of your old toilet at $300 comes to from $3,980*.
Can I replace a toilet myself in NSW?
No. The NSW Government says plumbing and drainage work needs a licence whatever it costs, so a licensed plumber has to do it. Our installs are done by licensed plumbers, who give you a certificate of installation.
How long does a toilet replacement take?
The Quote Yard puts a like-for-like swap at 1 to 2 hours and a close-coupled suite at 2 to 3 hours. With LORENTIS, replacing a toilet with a smart toilet takes 1 day for the electrical work and 1 day for the plumbing.
Does a new toilet have to match the old one?
It has to suit the same connections. Check the trap type, the set-out from the wall to the centre of the waste, and where the water outlet sits. If they don't match, the plumber may need extra fittings or pipework, which costs more.
Is removing the old toilet included in the price?
It depends on the quote. WaterFix includes removal and disposal in its toilet replacement packages. The Quote Yard says removal and disposal adds $50 to $150 where it isn't already in the quote. LORENTIS charges +$300 to remove your old toilet.
Do I need a power point to replace a toilet with a smart toilet?
Yes. Every LORENTIS model needs a power point near the toilet. If there isn't one, LORENTIS arranges one for +$1,100, a fixed price across Sydney metro.
Should I repair or replace my toilet?
A single worn part on a sound toilet is usually worth repairing. A cracked pan or cistern, a leak at the base that keeps coming back, or repeat repairs on an ageing suite point to replacing it. Ask your plumber to price both.
