Plumbing Cost Calculator
Plumbing quotes swing wildly because the job, the timing and the access all move the number. Pick the work you need, when you need it and what the plumber will run into, and the calculator returns a realistic Australian bracket.
Australian law requires a licensed plumber for almost all work beyond changing a tap washer or a showerhead, and a Certificate of Compliance for notifiable work. Unlicensed plumbing can void home insurance and has to be redone before a sale settles.

- Materials and fixtures$150
- Call-out, disposal, compliance$50
💰 Ways to save
- Batch small jobs into one visit. Most of the cost of a $180 tap repair is the call-out and the first hour, so having the plumber replace three washers, refit a wobbling toilet and check the hot water tempering valve in the same attendance costs far less than three separate visits. Keep a running list on the fridge and call once.
- Ask for a CCTV camera inspection before you approve any drain excavation. A $250 to $400 camera run tells you whether you have a root intrusion at one join, a collapsed section or simply a build-up, and it turns an open-ended dig into a defined repair. Plumbers who quote excavation without looking first are pricing in their own uncertainty and you pay for it.
- For a repipe, get the make-good scope written into the quote rather than left as an assumption. Opening walls to replace galvanised pipe is the easy part; patching, sealing, re-tiling and repainting is often a third of the true project cost, and it is the line most commonly missing when a repipe quote looks unusually sharp against its competitors.
- Avoid emergency rates where the situation allows. Learn where your water meter isolation valve is and how to turn it off, because a burst pipe that you can isolate at 9pm becomes a normal-rate job at 8am rather than a double-time attendance with a minimum charge.

Understanding plumbing costs in Australia
What plumbers charge in Australia in 2026
Most Australian plumbers work on a call-out fee plus an hourly rate, or a fixed price for defined jobs. In 2026 the typical call-out sits between $80 and $160 and usually covers the first fifteen to thirty minutes, with hourly rates from $100 to $150 in regional areas and $130 to $190 in Sydney, Melbourne and Brisbane metro. Specialist work such as drain jetting, gas fitting or backflow testing carries higher rates again. That structure explains why small jobs feel disproportionately expensive: a fifteen minute washer replacement can still land at $150 to $220 once the call-out and travel are covered, which is exactly why batching small tasks into a single visit matters so much.
Typical prices for common jobs
Working from the small end up, a leaking tap or washer replacement runs about $150 to $280, a blocked drain cleared with an electric eel $180 to $450, and high pressure jetting $350 to $700 depending on the length and severity of the blockage. A toilet replacement including the pan, cistern and connection lands around $400 to $800 for the plumbing labour with the fixture on top. A burst pipe repair typically costs $400 to $1,200 depending on whether it is exposed, in a wall or under a slab. A hot water unit changeover, plumbing labour only, sits at $700 to $1,400. A bathroom rough-in and fit-off for a standard renovation runs $3,000 to $5,000 as the plumbing component of a larger project.
Repiping and replumbing an older home
Replumbing is the largest job most homeowners will ever hire a plumber for, and it comes up most often in homes built before the 1970s where galvanised steel pipe is still in service. Galvanised pipe corrodes from the inside, so the symptoms arrive gradually: falling pressure, rust-coloured water on the first draw in the morning, pinhole leaks appearing in clusters, and hot water taking longer to arrive. In 2026 a partial repipe covering the kitchen and bathroom wet areas typically costs $5,000 to $8,000, while a full house replumb in copper or PEX runs $10,000 to $18,000 for a standard three bedroom home and can exceed $25,000 for a large two-storey house or one with a concrete slab and limited access. PEX is faster to install and cheaper on labour because it runs in continuous lengths with fewer joins; copper costs more but remains the preference of many plumbers for exposed runs and hot water lines.
After hours, emergency and weekend loadings
The timing of the call is one of the biggest multipliers in plumbing and it is legitimate rather than opportunistic. After hours attendance typically carries a $150 to $300 fee before any work begins, evening and Saturday labour is charged at time and a half, and overnight, Sunday or public holiday work at double time with a one to two hour minimum. A blocked toilet cleared at 11pm on a Sunday can easily cost three times what the same job costs at 9am on a Tuesday. Where the situation can be contained safely, by isolating the water at the meter or shutting off a single fixture, waiting until standard hours is the single easiest saving in this entire trade.
Where quotes diverge and what to check
Two quotes for the same job separate on three things: what is assumed about access, whether make-good is included, and whether compliance work is priced. Concealed pipework, under-slab runs and second storey bathrooms all add labour that a quote written from a phone description will not have captured. Make-good, meaning patching walls, replacing sheeting and re-tiling after pipes are chased in, is frequently excluded from the plumbing quote and left to the homeowner to arrange, and on a repipe it can represent a third of the real cost. Compliance items such as backflow prevention devices, tempering valves on hot water systems and trade waste approvals are mandatory in many situations and appear as separate lines. Ask each plumber to state explicitly what is excluded, because that is where the difference actually lives.
Licensing, compliance and protecting yourself
In every Australian state and territory, plumbing beyond the most trivial maintenance must be carried out by a licensed plumber, and notifiable work requires a Certificate of Compliance issued to the property owner. Keep that certificate: it is the document a conveyancer will ask for at sale, and it is what your insurer will want if a failure causes water damage. Verify the licence number with the relevant state authority rather than taking a printed number at face value, confirm the plumber carries public liability insurance, and get anything above a few hundred dollars in writing with a scope, not just a total. Use the estimate above to sanity check the quotes you receive, then choose on scope clarity rather than on the lowest headline figure.
Frequently asked questions
How much do plumbers charge per hour in Australia?
In 2026 expect $100 to $150 an hour in regional areas and $130 to $190 in Sydney, Melbourne and Brisbane metro, plus a call-out fee of $80 to $160 that usually covers the first fifteen to thirty minutes. Specialist work such as drain jetting, gas fitting and backflow testing is charged at higher rates.
How much does it cost to replumb a house in Australia?
A full house replumb in copper or PEX typically costs $10,000 to $18,000 for a standard three bedroom home in 2026, and can exceed $25,000 for a large two-storey home or one on a slab with poor access. A partial repipe limited to the kitchen and bathroom wet areas usually runs $5,000 to $8,000.
When does a house need repiping?
Most often when galvanised steel pipe from before the 1970s starts to fail. The signs are falling water pressure, rust-coloured water on the first draw of the day, repeated pinhole leaks appearing in clusters, and hot water taking noticeably longer to arrive. Isolated leaks can be repaired, but once several appear in a short period the economics favour replacing the run.
How much more do emergency plumbers cost?
Typically two to three times standard rates. Expect a $150 to $300 after hours attendance fee, time and a half for evenings and Saturdays, and double time for overnight, Sunday and public holiday work with a one to two hour minimum. If you can isolate the water at the meter safely, waiting for business hours is the largest single saving in plumbing.
How much does it cost to clear a blocked drain?
An electric eel clearance runs about $180 to $450, while high pressure jetting costs $350 to $700 depending on length and severity. Add $250 to $400 for a CCTV camera inspection, which is worth doing before any excavation is approved because it converts an open-ended dig into a defined repair.
Is wall and floor make-good included in a plumbing quote?
Often not. Patching walls, replacing sheeting and re-tiling after pipes are chased in is frequently excluded and left to the homeowner to arrange separately. On a repipe it can be a third of the real project cost, so ask each plumber to state in writing whether make-good is in or out before comparing totals.
