Kitchen Sink Installation in Wilston
Fitting a new bowl touches four things at once: the sink, the mixer, the supply lines and the waste line. Kitchen sink installation in Wilston is licensed work at every one of those connections, and a licensed plumber handles them for Wilston homes and the suburbs around.

Replacing a kitchen sink, adding a second bowl or shifting the whole thing along the bench all sit on this page. It's part of the wider kitchen and laundry plumbing work we do, and the price is fixed in writing before anything starts.
From Old Sink Out to Leak Test
Connecting a kitchen sink means joining the hot and cold supplies through shut-off valves, the mixer, the waste outlet, the trap and the drain line, then a leak test. Each part has a job:
The supplies
each line gets its own shut-off valve, so the sink can be isolated without turning off water to the rest of the house.
The waste and trap
the basket waste locks into the bowl from below, and the trap keeps a plug of water that stops sewer smells rising back through the waste.
The dishwasher tie
where a machine drains into the sink waste, the new outlet needs a spigot for its hose. See dishwasher installation for that job in full.
The test
every joint gets run with water and checked before we pack up the tools.
How the Sink Style Changes the Job
A top-mount bowl sits on the bench with its lip overlapping the cut-out, while an undermount hangs beneath the benchtop and demands an exact, sealed edge. The style you pick changes the fitting work:
Top-mount
the lip hides a rough cut, laminate tops suit it, and the fitting is the simpler of the two.
Undermount
clips or brackets under the bench hold the bowl up, and silicone seals the exposed cut-out edge, so the cut has to be clean and true.
If the mixer is changing at the same time, our tap replacement page runs through the choices and the rules that apply.
What a Home Owner May Do Under the Sink
A licensed plumber makes every sink connection; a home owner in Queensland may not. The QBCC's owner summary lists sinks and taps as regulated work, and only a short unregulated list, items like a tap washer or jumper valve, stays open to you.
Where your job sits in the rules depends on what changes:
A straight swap
putting a new bowl where the old one sat is minor work. A licensee still does it, without a permit or any form to lodge.
A new or shifted sink
adding a second bowl or moving the old one is notifiable work. No council permit is needed, but we lodge a Form 4 with the QBCC within 10 business days of finishing, and your copy comes with us on the day.
An apartment kitchen
some apartment renovations need a local government permit, so unit owners should raise the plan with us before anything is ordered.
One product rule applies before you shop: any tapware, waste or connector fitted here has to be WaterMark certified and listed on the WaterMark product database.
Where a Kitchen Sink Leaks
Five spots account for nearly all sink leaks: a trap union, the seal around the basket waste, the mixer's base, a supply nut and the join where bench meets bowl. A slow one hides well:
A swollen cupboard base, a stale smell or a tide mark inside the cabinet
means water has been escaping even when nothing drips on the day you look.
Braided supply hoses
under the bench are a common weak point as they age, and our flexi hose replacement page explains why and when to swap them.
If the bowl itself blocks or drains slowly, that belongs on our blocked drains page rather than here, and we'll say so when you describe it.
What Changes the Price of a Sink Job
The price turns on five things: whether the bowl stays put, new supply or drain points, the room under the bench, the benchtop, and the tap and fittings. After a look at the job, the figure lands in a fixed written quote before any work starts.
One local wrinkle is worth raising early. On a pre-war house near Paling Avenue, the supply line is often original galvanised steel narrowed by a century of internal scale. A new mixer can still run weak unless the line is checked first, and the pipe is usually the culprit when flow disappoints, not the tap.

Kitchen Sink Questions Answered
Call (07) 3523 7172How does a plumber install a kitchen sink?
We isolate the supplies, disconnect the old bowl and mixer, then connect the new sink's waste, trap and supply lines and finish with a leak test. Every connection is licensed work, and you receive a copy of any Form 4 we lodge for the job.
Can I install a kitchen sink myself in Wilston?
No, the plumbing connections are licensed work in Queensland, and a sink is not on the QBCC's short unregulated list. Only small jobs like changing a tap washer or jumper valve stay open to a home owner.
How do I check my plumber is licensed?
The QBCC's online registers let you search a licence and see whether a Form 4 has been lodged for your property. Check the number before work begins, and keep the Form 4 copy we hand you at the end.
Who arranges a sink replacement in a rental property?
The owner or property manager holds the duty to keep the place in good repair, so repairs and replacements are theirs to arrange. A tenant needs written approval on a Form 23 before attaching a fixture or making a structural change, and that request should not be refused without good reason.
Can a kitchen sink be moved to a new spot in Wilston?
Yes, moving a sink is notifiable work in an existing home, so a licensed plumber runs new supply and waste lines and lodges a Form 4 within 10 business days. No council permit is needed.
