Kitchen Sink Size Guide for HDB & BTO Kitchens

Choosing a kitchen sink is not only about the design, it is about the size. Get it right and washing up feels easy while you still have counter space left to cook and prep. Get it wrong and either the bowl feels cramped or the sink swallows up the little counter you have.

For a new kitchen it is simple: choose the sink size that suits your counter space and the way you cook, and your carpenter builds the cabinet to match. For sink materials, bowl types and styles, see our main guide How to Choose the Right Kitchen Sink in Singapore.

Start with your counter space, not the sink

In many kitchens, especially compact HDB and BTO layouts, the counter run is short, and the sink has to share it with your hob, your prep area and somewhere to stack drying dishes. So the first question is not "how big a sink can I get?" but "how much counter can I give the sink and still have room to cook?"

A few simple guides help you get the balance right:

• Keep a proper prep zone. Try to leave a clear stretch of counter, ideally at least 450mm to 600mm, on one side of the sink for cutting, plating and a dish rack. This is where most of the real work happens.
• Do not crowd the hob. Leave a sensible gap between the sink and the cooker hob, so water and hot oil are kept apart and you have landing space beside each.
• Let the sink take its share, not all of it. As a rough guide, the sink should take up only about a quarter of your counter run. A bigger bowl is nice, but not if it leaves you nowhere to work.

Matching sink size to your kitchen

Once you know how much counter you can give the sink, match it to a size:

Compact single bowl (around 450mm to 520mm wide)

• Best for: shorter counters and tighter spaces, or anywhere you would rather keep more counter free for prep than give up room to a large basin. Pairs with a 600mm kitchen cabinet.

Standard single bowl (around 650mm to 720mm wide)

• Best for: a counter with a little more room to spare. A wide single bowl lets you lay big woks, baking trays and stockpots flat on the bottom. Pairs with a 750mm to 800mm kitchen cabinet.

Large or double bowl (around 780mm to 840mm wide)

• Best for: longer counters with plenty of room to spare, or households where two people often wash up together. Pairs with a 900mm kitchen cabinet or wider.

Tight on counter space? Consider a workstation sink

If your kitchen is compact and counter space is precious, a workstation sink is one of the smartest ways to get more done without a bigger counter. Instead of spreading your work across the countertop, you prepare inside the sink.

A workstation sink has built-in ledges along the top of the bowl, so accessories slide across it:

• A chopping board that sits over the bowl, so you cut vegetables right above the sink and sweep the scraps straight in.
• A colander for rinsing and draining rice, vegetables or noodles.
• A drying rack for washed dishes or produce.

Because you rinse, cut, drain and dry all within the sink's own footprint, a workstation sink effectively gives you a second work surface without taking up any extra counter. That makes it especially useful in a small HDB or BTO kitchen, where every centimetre of counter counts. It still fits a normal single-bowl opening, so you do not need a wider counter to enjoy it.

Understanding bowl depth

Depth affects both how comfortable the sink is to use and how much storage you keep underneath.

• Standard depth (180mm to 200mm): easy to reach into without leaning forward, and leaves the most room in the cabinet below for a water filter, cleaning supplies or a small bin.
• Deep bowl (210mm to 230mm): better at containing splashes when you wash large cookware under a strong tap, and hides dishes below the counter line. Just remember a deeper bowl hangs lower, so it leaves less height for tall items stored underneath.

Frequently asked questions

How much of my counter should the sink take up?

As a rough guide, aim for the sink to use only about a quarter of your counter run, and try to keep at least 450mm to 600mm of clear counter on one side for prep and a dish rack. In a compact kitchen, a smaller bowl that leaves you room to work often beats a large bowl that fills the counter.

What is the best sink for a small kitchen?

A compact single bowl keeps more counter free, while a workstation sink lets you cut, rinse and drain inside the bowl itself, giving you extra working space without a bigger counter. Both are good ways to make a small kitchen work harder.

Is a single bowl or double bowl better?

For most kitchens a large single bowl is more practical, as it lets you lay big pans, woks and baking trays flat. A double bowl splits the same width into two smaller basins, which suits those who like to separate washing and rinsing, but it needs a wider counter to feel comfortable.
