Kitchen Sink Installation & Replacement in Singapore
Whether upgrading to a bigger basin or fixing a leaky old one, a kitchen sink replacement is more involved than it looks — it touches the worktop, the plumbing and the seal. Here’s what to know.
Key takeaways
- Sink installation involves the basin, tap, waste, traps and seal.
- The sink type (top-mount, undermount) affects the fit to the worktop.
- A watertight seal and leak test are essential to avoid cabinet damage.
- Often paired with a new tap or a worktop change.
What’s involved
Fitting a sink means removing the old basin, preparing the worktop cut-out if the size differs, seating the new sink with a watertight seal, and reconnecting the tap, waste and trap. It’s then leak-tested before the cabinet below is put back to use.
Sink types and the worktop
A top-mount (drop-in) sink sits on the worktop and is the simplest swap; an undermount fixes beneath for a seamless look but needs a compatible worktop. If you’re changing sink size or style, the worktop may need adjusting — worth planning if you’re also updating the countertop.
Why the seal matters
The most important part is a proper seal and drainage connection — a poor seal lets water seep into the cabinet, warping it and feeding mould. Getting it watertight and tested is what makes the job last.
Frequently asked questions
Can any sink fit my worktop? Not always — size and mount type must suit the cut-out and worktop material.
Why is my sink leaking underneath? Usually a failed seal or a loose waste/trap connection — both fixable.
Should I replace the tap at the same time? It’s convenient to — and avoids a second visit.
Do I need a plumber? For a watertight, tested install, yes — it protects the cabinet below.
