The work sits inside our kitchen and laundry plumbing service. If you are new here, the Strathpine home page maps everything we cover.
A sink that will not drain is a different problem, and it belongs on our blocked drains page. This page is about the fittings above the floor.
From Old Sink Out to Leak Test
A sink connection runs through five links: each supply line with its isolation valve, the mixer, the basket waste, the trap and waste pipe, and a final leak test. Here is what each part does:
Isolation valves
each supply line gets its own shut-off, so the sink can be closed off without killing water to the rest of the house.
The mixer
the hot and cold supplies terminate here, and the connections get checked for weep as part of the test.
The basket waste
the collar and washer that close off the drain hole in the base of the bowl, a common leak point when the rubber ages.
The trap
the bent fitting under the bowl holds a water seal that stops sewer gas coming up the waste pipe.
The leak test
water runs through the full assembly with the cupboard dry underneath, so any escaping joint shows straight away.
One extra detail matters if you have a dishwasher. The machine usually pumps its waste into a spigot on the sink trap, so the new waste needs that spigot fitted; see our dishwasher installation page for the machine side of the job.
Tapware, wastes and connectors sold for installation here also carry WaterMark certification and appear on the official product database. We check that before anything goes in.
What a Home Owner May Do Under the Sink
In Queensland, a licensed plumber fits the sink: a new or relocated bowl is notifiable work reported on a Form 4, and a same-position swap is minor work. The difference between the two categories decides the paperwork.
Notifiable work is plumbing done in a building that already stands. No council permit is needed, but the plumber lodges a Form 4 with the QBCC within ten business days of completing the job, and hands you a copy for your records.
Minor work still belongs to a licensee. A straight swap of the bowl in the same position needs no permit and no Form 4, because nothing new is being added or moved.
Renters follow one more step. A tenant needs the owner or manager's written okay on a Form 23 before a fixture goes in, and that approval cannot be refused without a good reason.
How the Sink Style Changes the Job
A top-mount sink sits on top of the cut-out on its own rim, while an undermount is fastened beneath the bench and leaves the cut edge on show. That single difference changes most of the fitting work.
A top-mount hides a rough cut, which is why it suits laminate benchtops and simpler jobs. The rim drops over the opening and seals against the bench.
An undermount reverses the arrangement. Clips or support brackets carry the bowl's weight from below, and the exposed edge gets cut precisely and sealed with silicone, because water sits against that edge every time the bench is wiped down.
The mixer itself is a separate decision. Choosing and fitting the tap is covered by our tap replacement page.
Like for Like or a New Position
The price turns on five things: keeping the existing position or moving it, adding water or waste connections, the room to work under the bench, the benchtop material and the tapware you choose. No dollar figure applies until the job has been scoped on site, because two houses rarely match on those five points.
The quote then arrives in writing before any work starts. Nothing proceeds without your go-ahead.
The suburb's stock splits the work two ways. Area-level figures record 60 dwellings approved in 2021-22, so a share of installs go into fresh kitchens in new attached housing. Most jobs, though, replace fittings in the older detached houses west of the centre, the brick-veneer stock from the estates once marketed as Little Aspley.
Where a Kitchen Sink Leaks
Five spots account for most under-sink leaks: a weeping trap joint, the basket waste seal, the mixer base, a supply join, and the seam between bowl and bench. Each one has a different fix, and the leak test after installation checks all five.
Some leaks stay quiet. A cupboard base that has swelled, a stale smell behind the doors, or a tide mark on the cabinet floor tells you water has been escaping slowly even with no visible drip.
One local pattern deserves a mention. Houses here that had kitchens modernised years ago often still carry the braided hoses from that reno, and hoses past their rated life let go suddenly under a sink. Our flexi hose replacement page covers that swap.

Kitchen Sink Questions From Strathpine
Call (07) 3524 7163Can I legally install my own kitchen sink?
No, you cannot. A sink is regulated plumbing, so the law puts the job with a licensed plumber. The QBCC's unregulated list is short and covers small items such as a washer or jumper valve inside a tap; a sink does not appear on it.
How do I check my plumber is licensed?
Yes, easily. The QBCC keeps online registers you can search free: one shows whether a plumber holds a licence, and another shows whether notifiable paperwork sits against your address. Get the licence number when you book and confirm it there.
Is a top-mount or undermount sink easier to fit?
Yes, a top-mount is the easier fit. The rim covers the cut edge, so the opening needs no perfect finish, and laminate benches suit it. An undermount leaves the edge exposed, so the cut needs precision, a silicone seal, and brackets or clips to hold the bowl.
Why is water leaking under my kitchen sink in Strathpine?
Usually one of five joints: the trap, a waste connection, the washer in the basket waste, the mixer base, or the seam between bowl and bench. A cupboard floor that stays damp or swells means a slow leak even without a visible drip.
Does replacing a kitchen sink need a council permit in Strathpine?
No, it does not. A same-position swap is minor work with no permit and nothing to lodge. A new or moved sink is notifiable work, which still needs no council permit, though units and buildings on a combined drain can require one, so ask the plumber first.
