For most Singapore homes doing daily wok cooking, a two-burner or three-burner gas hob with at least one high-BTU wok burner (around 4 kW or higher) and a standard 60 cm cutout is the practical sweet spot. If your kitchen is genuinely compact or your gas point is awkwardly positioned, a 30 cm domino gas hob paired with another cooking appliance is worth considering.
The question most buyers ask is "gas or induction?" The more useful question is: if you have settled on gas, which gas hob actually fits your kitchen, your cooking style, and the piping that is already in the wall? A wrong cutout size means a rework. An underpowered burner means your wok never gets hot enough. An oversized four-burner unit in a narrow galley kitchen means you cannot open drawers on one side. This guide works through those specifics so you can make the technically correct call, not just pick whatever looks good in the showroom.
What Actually Separates Gas Hobs from Each Other
Gas hobs look similar on a webpage. On paper they all have burners, knobs, and a stainless or tempered glass surface. The differences that matter in daily use are burner output (BTU or kW), the number and configuration of burners, ignition quality, and how the hob handles a safety shutoff if the flame goes out. Entry-level units often skip the flame-failure device on every burner, which is a gap worth flagging when you compare specifications.
Surface material also matters more than it seems. Tempered glass tops are easier to wipe but chip if you drop a cast-iron pan wrong. Stainless steel and enamelled steel tops are more forgiving of impact but collect grease around the burner crowns. In Singapore's humidity, anything with deep grooves and crevices around the trivet supports becomes a cleaning chore within weeks.
Burner Count, Configuration, and BTU Output
The common configurations in Singapore are two-burner (typically around 60 cm wide), three-burner (usually 75-90 cm), and the single-zone 30 cm domino format. Four-burner units exist but a 90 cm-plus cutout is rare in HDB and most condo kitchens.
BTU output per burner is where the spec sheet earns its keep. A standard burner runs at roughly 1.5-2 kW, which is fine for simmering sauces or boiling water. A wok burner needs to be meaningfully higher, typically in the 3.5-5 kW range, to generate the sustained flame height and heat distribution that gives char-grilled vegetables their flavour. If a hob lists all its burners at identical output, that is a hint none of them is truly optimised for wok work.
Three-burner models often arrange two standard burners flanking a central high-output wok burner, which is a sensible layout for a household that cooks rice, soup, and stir-fry simultaneously. Two-burner models are genuinely sufficient for one or two people cooking simple meals, but can feel limiting during Chinese New Year prep or any gathering that involves multiple pots at once.
Cutout Sizes, Kitchen Fit, and Piping Placement
The cutout dimension your countertop requires is not negotiable once the stone is cut. Common built-in gas hob cutout widths run at approximately 30 cm for a domino unit, 60 cm for a two-burner, and 75-90 cm for three-burner models. Always cross-reference the exact cutout dimensions in the product specification sheet against your countertop measurement, with allowance for the overlap frame of the hob itself.
Piping placement is the factor many buyers only discover mid-renovation. The gas inlet on a built-in hob is usually located at the rear or one side. If your existing gas point is on the opposite side, you will need the piping rerouted, which requires a licensed gas service worker, not a general contractor. That rerouting adds time and cost to your renovation schedule, and it is the kind of detail worth clarifying with your renovation contractor before you order the hob.
For genuinely smaller kitchens where 60 cm of continuous counter space is not available, a domino gas hob at 30 cm is a serious option. You lose one burner, but you gain flexibility to pair it with an induction domino or a teppanyaki plate in the adjacent slot, giving you more cooking modes in a narrow run.
Gas Type, Ignition, and Safety Features
Singapore runs on town gas (reticulated) in most residential properties, with some older estates and landed homes using LPG cylinders. Not all gas hobs are set up for both gas types out of the box, and using an LPG-rated hob on town gas (or vice versa) without the correct conversion kit affects flame performance and can be unsafe. Confirm the gas type in your home and check that the hob you are buying is rated for it, or that a conversion kit is included and properly installed.
Auto-ignition (piezo electric spark on every burner) is now standard on decent models. The more meaningful safety feature is a flame-failure device (FFD) on every burner, not just the main wok burner. An FFD cuts the gas automatically if the flame is extinguished by a boilover or a draught. Some budget units include it only on one or two burners, and that partial coverage is worth knowing about before you buy.
Cast-iron trivets are heavier and more stable than enamelled steel ones, and they distribute load better for heavy pots. The downside in Singapore's climate is that cast iron will rust if left wet. A quick wipe after cooking is not optional.
Gas vs Induction: The Honest Trade-off
Gas has genuine advantages. The flame responds instantly to every knob adjustment, there is no latency between your input and the heat change. A wok can be lifted and tilted without losing heat, which matters for tossing vegetables at high heat. And every pan type works, including uncoated carbon steel and cast iron that would be fine on induction anyway but also the older aluminium pots that are not magnetically compatible.
Induction has its own real case. Induction hobs heat only the base of the pan, not the air around it, which keeps the kitchen notably cooler in Singapore's year-round heat. Spillovers sit on a cool glass surface rather than baking onto a live burner, so cleanup is faster. If your kitchen lacks a gas point entirely, or your HDB unit uses only electrical supply in the kitchen area, induction is not a stylistic preference but a practical necessity.
The trade-off to weigh honestly: induction requires magnetic (ferrous) cookware. If you cook a lot with a thin-walled aluminium wok or old non-magnetic pans, the switch to induction means replacing those too. And for families where high-heat wok cooking is daily rather than occasional, many cooks simply prefer working with a visible flame. Neither choice is universally correct.
Choosing by Kitchen Type
This is where condition-specific guidance matters more than general principles.
HDB galley kitchen with an existing gas point
A two-burner gas hob at 60 cm is usually the right answer. It fits the standard countertop run, uses the existing gas infrastructure, and leaves room beside it for a small prep area. If cooking volume is high, check the wok burner BTU figure before assuming any two-burner is equivalent to another.
Condo or resale flat with a wider island or peninsula
A three-burner unit in the 75-90 cm range opens up simultaneous cooking without cramping the layout. Verify the countertop material can handle the cutout dimensions, some engineered stone edges are fragile at narrow spans.
Studio or compact kitchen with limited counter space
A 30 cm domino gas hob gives you a gas flame for wok cooking without occupying the full 60 cm run. Pair it with a countertop induction unit if you need a second heat source, which keeps both options without doubling the built-in footprint.
Landed home or kitchen with full renovation flexibility
You have the most options here. A three-burner or even four-burner unit is viable if the countertop run is long enough and the gas piping can be positioned centrally. Bear in mind that a larger gas hob over a large oven below means a very warm cooking zone, adequate ventilation and a powerful hood become more important, not less.
Browse the gas hob range to compare burner configurations and cutout dimensions across available models. Filter by burner count and use the specification sheets to cross-reference your countertop measurement before confirming.
Frequently Asked Questions
Do I need a licensed technician to install a gas hob in Singapore?
Yes. Gas piping connections in Singapore must be carried out by a licensed gas service worker registered with the Energy Market Authority. This applies to new installations and to any rerouting of existing piping. A general contractor or handyman cannot legally perform the gas connection. Factor this into your renovation schedule and budget from the beginning.
Can I use any cookware on a gas hob?
Gas works with virtually all cookware types, including aluminium, copper, cast iron, stainless steel, ceramic, and carbon steel. There is no magnetic compatibility requirement as there is with induction. The main consideration is trivet stability: lightweight pans on wide-spaced trivets can wobble, so check the trivet design if you regularly use small saucepans.
What cutout size should I plan for if I am renovating now?
Standard cutout widths for built-in gas hobs are approximately 30 cm (domino), 60 cm (two-burner), and 75-90 cm (three-burner). Always use the exact cutout dimensions from the specific product's specification sheet, not a general rule. Have your countertop fabricator confirm the measurement before cutting, adjustments after the stone is cut are costly and sometimes impossible.
What is a flame-failure device and do I need it on every burner?
A flame-failure device (FFD) automatically shuts off the gas supply to a burner if the flame is extinguished unexpectedly, such as by a boilover or a draught. It is a meaningful safety feature. Some lower-cost models include it on only one burner. For a household with children or anyone who cooks at a rapid pace, FFD coverage on all burners is the safer specification to prioritise.
Is a gas hob cheaper to run than induction in Singapore?
It depends on gas and electricity tariff rates at the time, and how efficiently each is used. Gas transfers heat through a flame, so some energy escapes around the pan base; induction transfers heat directly through the pan base, making it more thermally efficient for most cooking tasks. Running cost comparisons shift as tariffs change, so check current rates from SP Group and your gas retailer rather than relying on a fixed figure.
The Right Hob Fits More Than Just the Countertop
A gas hob that matches your cutout, your gas type, your burner count, and your actual cooking habits will outlast one that was simply the easiest choice to make on the day. If wok cooking at high heat is a near-daily activity and your kitchen already has a gas point in the right position, a well-specified gas hob with a genuine high-BTU wok burner is hard to argue against. If you are starting a renovation from scratch and have flexibility on cooking technology, it is worth sitting with the induction option too before committing the countertop.
