Dishwasher Installation Cost Sydney 2026, Plus Ovens, Cooktops and Washing Machines
Installing a dishwasher costs about $100 to $200, a cooktop $120 to $500 and a washing machine $70 to $180 on published Australia-wide marketplace ranges (Airtasker, updated 9 April 2025), before any plumbing or gas work the install turns out to need. Those are market figures, not Mr Splash prices. Below: what each install involves, what pushes the price up, and how a fixed quote works.
Those figures cover a straightforward swap. A first-time install that needs a new water point, a drain connection, a gas line or a compliance certificate is a plumbing or gas job on top, and Sydney plumbers charge $92 to $230 an hour on the market (whatsthedamage.com.au, verified September 2026). None of these are Mr Splash prices: every Mr Splash install is one fixed price, GST included, confirmed before any work starts.

What a Dishwasher Installation Involves
A dishwasher needs three things: a cold water supply with an isolation tap, a drain connection, and power. In a kitchen that already had a dishwasher, all three exist and the job is a swap: disconnect the old machine, connect the new inlet hose to the isolation tap, clamp the drain hose high onto the sink trap spigot or a dedicated waste, level the machine, and run a test cycle while checking every joint for weeping.
A first-time install is where the price moves. If there is no isolation tap under the sink, one has to be fitted. If the sink trap has no spigot, a dishwasher trap or a separate waste is needed. If the machine is going into an island bench, the water and drain may need to be run under the floor. Each of those is plumbing work, and it is what separates a swap from an install.
The details that matter for the warranty: the drain hose must rise above the trap before it drops (the high loop) so waste water cannot siphon back, the inlet hose must be the one supplied with the machine, and the isolation tap must be reachable without pulling the dishwasher out. Mr Splash installs dishwashers across Sydney; the dishwasher installation page has the details and the booking form.
Ovens and Cooktops: When It Is a Gas Job
An electric oven or cooktop is an electrician's job if it is hardwired, and a plug-in appliance can be positioned by anyone. A gas oven or gas cooktop is different: in NSW connecting a gas appliance is licensed gasfitting work, and the gasfitter must test the connection for leaks and issue a certificate of compliance when the work requires one. That is the part of the job you are paying for, not the lifting.
What moves a gas install price: whether a gas bayonet or supply point already exists at the right spot, whether the existing regulator suits the new appliance, whether the run from the meter needs to be extended, and whether the old appliance was connected with a hose that does not meet current standards. A like-for-like changeover on an existing point is quick; a new gas point is a gas line job quoted on the run.
Mr Splash's licensed gasfitters install and certify gas cooktops and ovens across Sydney. The gas oven installation page covers what is checked on every connection.
Washing Machine Installation
A washing machine needs hot and cold laundry taps, a drain (a standpipe or a laundry tub), and power. The published market range of $70 to $180 (Airtasker, Australia-wide, updated 9 April 2025, not a Mr Splash price) reflects a swap where all three exist: connect the hoses, hook the drain hose into the tub or standpipe, level the machine and test.
The extra work comes from old laundry taps that seize or drip once the hoses are moved, a drain that overflows because a front loader pumps out faster than the old standpipe can take, or a laundry with no taps at all where a new set has to be fitted. The most common call after a DIY install is a slow leak from a hose washer or a cross-threaded fitting that has been running into the floor for weeks.
The washing machine installation page has the booking form and the checklist a plumber runs on every install.
What Changes the Price of an Appliance Install
Swap or First Install
Existing water, drain, gas and power points make it a swap. Creating any of them makes it a plumbing, gas or electrical job.
Where the Appliance Goes
Under an existing sink is simple. An island bench, a new laundry or a cooktop in a fresh benchtop cut-out means running services to it.
Old Fittings
Seized isolation taps, dripping laundry taps and non-compliant gas hoses get found the moment the old appliance comes out, and they need replacing before the new one goes in.
Compliance
Gas work needs a licensed gasfitter and, where required, a certificate of compliance. It is part of the job, not an extra.
Removal and Disposal
Taking the old appliance away is quick if it is in the quote and awkward if it is not. Ask.
Time of Day
An appliance install is rarely an emergency. Booking business hours avoids any after-hours fee, which is always confirmed before attending anyway.
How to Get a Fixed Price for an Installation
- Photograph the space: under the sink, the laundry taps and drain, or the cooktop cut-out and the gas point, whatever the appliance connects to.
- Send the appliance details, the make and model, or a photo of the spec plate, so the right hoses, regulator or trap are on the van.
- Say whether it is a swap or a first install, and whether the old appliance needs taking away.
- For gas, say what is there now: a bayonet, a fixed connection, or nothing.
- Get the fixed price, GST included, before booking. Mr Splash confirms it from the photos and it does not change unless you change the job.
Appliance Installation Questions, Answered
How much does it cost to install a dishwasher?
Published marketplace ranges put a dishwasher installation at $100 to $200 Australia-wide (Airtasker, updated 9 April 2025; ServiceTasker, 29 December 2023) for a like-for-like swap. A first install that needs a new isolation tap, a drain spigot or services run to an island bench is plumbing work on top. Those are market figures, not Mr Splash prices: Mr Splash confirms one fixed price, GST included, from a photo of the space.
How much does it cost to install a gas oven or cooktop?
Marketplace ranges put cooktop installation at $120 to $500 Australia-wide (Airtasker, updated 9 April 2025), not a Mr Splash price. In NSW a gas connection is licensed gasfitting work, leak-tested and certified where required, and the price depends on whether a gas point already exists at the spot. Mr Splash quotes gas installs as one fixed price after seeing the existing connection.
How much does it cost to install a washing machine?
The published market range is $70 to $180 Australia-wide (Airtasker, updated 9 April 2025) for connecting a machine to existing laundry taps and a drain, not a Mr Splash price. Seized taps, a drain that cannot keep up with a front loader, or a laundry with no taps add plumbing work, which is quoted as a fixed price before it starts.
Do I need a plumber to install a dishwasher?
For a swap onto an existing isolation tap and drain spigot, a competent installer can do it. Fitting a new water point, cutting a drain connection into the trap or running services to a new location is plumbing work that in NSW must be done by a licensed plumber. Mr Splash Plumbing holds NSW Lic 306457C.
Can a plumber install a gas cooktop?
Only a licensed gasfitter can connect a gas appliance in NSW. Mr Splash's gasfitters install and certify gas cooktops and ovens, test every connection for leaks before the appliance is turned on, and provide the compliance paperwork where the work requires it.
Are the prices on this page Mr Splash prices?
No. The installation ranges are Australia-wide marketplace figures and the hourly figure is a Sydney market rate, each named and dated beside the figure. Your own Mr Splash price is one fixed quote, GST included, confirmed before any work starts, with no charge just to come and look during business hours.
