What a Kitchen Sink Replacement Includes
A replacement brings the hot and cold supplies up to the tap, seals the basket waste into the bowl, hooks up the trap and waste pipe, then puts every joint through a leak test. That is the whole job, start to finish.
The parts in order:
Isolation valves
a valve on each supply line shuts the water at the sink alone, so the rest of the house stays on.
Supply connections
the hot and cold lines run from the house supply to the tap.
Basket waste
the strainer that seals the drain hole in the bowl.
Trap
the bend holds a water plug that keeps sewer gas down in the drain instead of the kitchen.
Leak test
we run the water and check every joint before packing up.
A dishwasher's drain hose usually clips to a spigot on the sink's waste pipe, so the new waste needs that fitting whenever a machine shares the line. Our dishwasher installation page covers that connection in full, and filtered water at the new bowl is a water filter installation job we quote separately.
Who May Fit a Kitchen Sink in Queensland
Queensland law puts every sink connection in licensed hands. A brand-new sink, or one shifted to a different spot in an existing house, counts as notifiable work, while a straight swap in the same position counts as minor work.
What that means for you:
Notifiable work
no council permit applies, and we report the job to the QBCC on a Form 4 inside 10 business days of finishing.
Minor work
a QBCC licensee still does the replacement, but no form gets lodged.
Your copy
the Form 4 we give you goes into the property's records.
Checking us
the QBCC's registers are searchable online, so you can confirm a licence and see whether a form exists for your address.
Tapware, wastes and connectors fitted here need WaterMark certification and a listing on the WaterMark product database, which is what keeps the installation compliant.
Drop-In and Undermount Sinks Compared
A drop-in sink sits proud of the bench with its lip overlapping the opening, while an undermount is carried from beneath the benchtop and needs an exact, sealed edge. The benchtop usually decides which one suits.
Drop-in (top-mount)
the lip overlaps the opening and covers a less-than-perfect cut, which suits laminate benches and keeps the fit straightforward.
Undermount
brackets or clips carry the bowl's weight from below, leaving the cut-out edge on show.
Sealing
silicone protects that exposed edge, since it cops water every time the bench gets wiped.
What Changes the Price of a Sink Job
What you pay turns on a handful of things we can only judge on site:
- whether the bowl stays put or shifts position
- whether fresh supply or waste points get run
- the reach-in room under the bench
- the benchtop
- the tapware and fittings you choose
We set the price in a fixed quote once we've seen the job. A same-position swap is the simplest version; moving the bowl across the kitchen adds pipework and turns the job notifiable, which brings the Form 4 with it.
Picking new taps at the same time? Our tap replacement page shows what that involves.
Trap, Waste and Seal Problems
Leaks under a kitchen sink start at five spots: the trap or waste joint, the basket waste's seal, the tap base, a supply join, or the seal between bowl and benchtop. The cupboard usually tells the story first.
Signs worth a visit:
- a swollen cupboard floor, a musty odour or staining beneath the bowl, even with no drip visible
- water pooling around the basket waste as the bowl empties
- a weeping joint at the trap you can see when you open the doors
A bowl that drains slowly is a blockage rather than a leak, and our blocked drains page owns that one. For the braided hoses behind many sinks in these 2000s homes, see our flexi hose replacement page.
Sink Work in a Growing Suburb
Area-level figures put this suburb's population growth at 4.3 per cent between 2020 and 2025, with building approvals adding 289 dwellings across five years. Most homes around The Corso and its feeding streets are detached family houses finished from the 2000s onward, so the sinks we open up are mostly renovation upgrades rather than original fit-outs.
Renovations are the common thread. A kitchen reno in an existing house is notifiable work too, so the same Form 4 process covers a sink that moves as part of a bigger refit.
Apartment owners should raise it with us first, because some apartment renovations need a local government permit. The laundry tub runs on the same supply-and-waste logic, and our laundry plumbing page covers it.

Kitchen Sink Questions Answered
Call (07) 3520 4094Do I need a plumber to install a kitchen sink?
Yes, the QBCC's guidance for owners lists sinks among the fixtures only a QBCC-licensed plumber or drainer may fix or replace, and its short list of licence-free owner jobs leaves sinks off. We handle the connections, the testing and any paperwork.
Can I install a kitchen sink myself in North Lakes?
No, the water and waste connections are licensed work in Queensland. The QBCC allows owners only a brief list of licence-free jobs, such as swapping a tap washer, and a full sink fit-out sits outside it.
How much does it cost to fit a kitchen sink?
It depends on where the bowl goes, whether fresh pipework is run, the space beneath the bench, the benchtop and the fittings. We set the figure in a fixed quote after seeing the job.
Does a dishwasher connect to the kitchen sink waste?
Yes, in most homes. The machine's drain hose clips to a spigot on the sink's waste pipe, so the new waste needs that fitting whenever a dishwasher shares the line. Our dishwasher installation page covers the rest.
Who arranges a kitchen sink replacement in a North Lakes rental?
The owner or manager keeps the duty to keep the premises in good repair. Queensland tenancy law says a tenant needs written sign-off on a Form 23 before fixing a fixture to the premises or altering the structure, and a refusal needs a reasonable basis.
