Why do sinks and basins leak?
The bottle trap is the common wash trap under HDB sinks and basins. It holds water to block sewer smells and catches debris, so it is also where most leaks and chokes start: its seals wear, and it can loosen when it is unscrewed for cleaning. The waste, the outlet fitting in the sink or basin itself, has a seal that hardens over time. Water seeping around the edge of a basin usually means the silicone seal has failed.
Do you need a licensed plumber to replace a basin?
No. PUB lists installing, replacing or removing any washbasin or sink, including the bottle trap below it, as simple plumbing work that a handyman without a licence may do. Moving or extending the water supply pipes to a new position is regulated work for a PUB-licensed plumber, so plan the pipework with one if you are relocating a sink during renovation.
Sinks and basins in HDB flats, condos and landed homes
- HDB flats: basins are usually wall-hung or set into a vanity, with a bottle trap and flexible hoses below. Kitchen sinks are typically stainless steel, set into the countertop.
- Condos: undermount sinks and countertop basins are common. An undermount sink is bonded under a stone countertop, so replacing one needs more care.
- Landed homes: older homes may have pedestal basins and older pipes, and matching new fittings to old pipes can need adaptors.
Common problems
Water dripping under the sink or basin: a loose or worn bottle trap, a waste seal that has hardened, or a leaking hose. Water seeping around the basin edge: the silicone between the basin and the wall or countertop has failed. Bad smell from the sink: a dirty or dried-out bottle trap. Basin is loose or tilting: the wall brackets or fixings have loosened. Cracked or chipped basin: replacement is the lasting fix, because cracks spread. Slow draining: a partial choke in the bottle trap or waste (see Choke Clearing). Kitchen sink coming away from the countertop: failed sealant or loose clips under the sink.
What the work covers
We find the leak first, then reseal or replace the trap, waste or hose that is causing it. For a basin or sink replacement, the old unit is disconnected and removed, the new one is fixed and levelled, and the waste, trap and supply hoses are connected. Edges are sealed with silicone, and the water is run to check every joint for leaks.

FAQs
At SG QuickFix, sink and basin leak repairs start from $70. If the bottle trap or waste needs replacing, labour starts from $80 plus the part. Most leaks under a sink are fixed in 30 to 60 minutes.
Basin replacement labour starts from $160 when you supply the basin. Supplying and installing a basic basin starts from $250. Kitchen sink replacement labour starts from $180.
No. PUB lists installing or replacing a washbasin or sink, including its bottle trap, as simple plumbing work that doesn't need a licensed plumber. Moving the water supply pipes to a new position is licensed work.
A bottle trap is the fitting under a sink or basin that holds water to stop sewer smells and catches debris. HDB notes it is the common wash trap in HDB flats. It unscrews for cleaning, which is also why it can leak when its seal wears.
Usually food and grease are decaying in the bottle trap or waste pipe, or the trap has dried out. Cleaning the trap often fixes it. If the smell continues, the waste pipe may be partly blocked.
Replacing a drop-in kitchen sink usually takes two to four hours, including removing the old sink, fitting the new one, connecting the waste and sealing the edges. Undermount sinks under stone countertops take longer.
Yes. A new basin is a good time to change the tap too, since both are disconnected anyway. Tap replacement is priced under Tap Repair & Replacement, from $65 plus the tap.
