Kitchen Appliance Planning: What to Buy Before Your Carpentry Is Built

Choose your major kitchen appliances before your carpentry is built, not after. Your hob, oven, cooker hood, fridge, sink and dishwasher all have fixed dimensions and specific power and water requirements, and your cabinets, worktop cut-outs and electrical points must be built around those exact models. Confirm the appliances first, hand the spec sheets to your contractor and interior designer, then let the carpentry follow.

This is the single most common ordering mistake in a Singapore kitchen renovation. HDB and condo kitchens are compact, so a fridge that is 5cm too wide, an oven that needs a 16-amp point where only a 13-amp socket was wired, or an induction hob that does not clear the drawer below can force costly rework. Appliances lead, carpentry follows, and a little planning up front saves you from tearing out finished cabinets later.

Why buy appliances before the carpentry?

Carpenters build cabinets and cut the worktop to match the exact appliance model you give them. A built-in oven, an induction hob and a cooker hood each need a precise opening, and those cut-outs are permanent once the stone or laminate top is fabricated. If you buy the appliance later, you are gambling that a future model will fit an opening decided months earlier.

Power and plumbing are the other half of the story. Different appliances need different points: a standard 13-amp socket, a dedicated higher-rated circuit for an oven or induction hob, a water inlet and drain for a dishwasher, and a socket positioned where the fridge will actually stand.

- Built-in oven: usually needs a dedicated higher-amp circuit, not a shared kitchen socket

- Induction hob: high power draw, often wants its own circuit and correct cable size

- Dishwasher: needs a water inlet, a drain point and a nearby socket

- Fridge: needs a socket in the right spot plus breathing space around it for heat

Which appliances must be confirmed first?

Prioritise anything that is built in or boxed in by carpentry, because those are the hardest to change afterwards. Free-standing items that simply plug in and sit on the floor give you more flexibility, but their footprint and clearances still shape the layout.

- Confirm early (built-in or boxed in): hob, cooker hood, built-in oven, built-in microwave, integrated dishwasher, sink and tap

- Confirm the size and position (free-standing): fridge, washing machine, dryer, water heater, and any tall larder appliance

- More flexible (plug and play): kettle, air fryer, rice cooker, blender and other countertop gadgets you can add anytime

How do I match appliances to power points and wiring?

Give your electrician the appliance spec sheets before first fix wiring, so points are placed and rated correctly. In Singapore, high-load appliances such as built-in ovens, induction hobs and some instant water heaters may need a dedicated circuit rather than a shared 13-amp socket, and the cable size and breaker must match the load. This is licensed electrical work and should be done by a competent professional.

Plan socket positions to the millimetre. A socket hidden behind a fridge is fine, but a socket where a tall cabinet will sit is wasted. Mark where the cooker hood ducting will run, where the hob's isolator switch goes, and whether your kitchen has enough countertop sockets for daily gadgets.

- List every appliance and its rated power before wiring is finalised

- Ask whether any appliance needs its own dedicated circuit

- Decide induction versus gas early, since it changes both wiring and whether you keep a gas point

- Add a few extra countertop sockets now; retrofitting them later means hacking finished walls

Where should I buy kitchen appliances in Singapore?

For major appliances, Singapore homeowners commonly compare large electronics and department retailers such as Courts, Harvey Norman, Gain City and Best Denki, alongside brand showrooms and the appliance sections of stores like IKEA. Compare the same model across a few sellers, and always ask about installation, delivery, warranty and whether removal of your old appliance is included.

Prices vary widely by brand tier and features, so treat any figure as a rough guide and check current pricing before you commit. As a very general sense of entry to mid-range built-in appliances, expect an induction or gas hob from around S$400 to S$1,200, a built-in oven from around S$700 to S$2,500, a cooker hood from around S$300 to S$1,200, and a fridge from around S$700 upward depending on size and features.

- Bring the exact model number to your contractor, not just the brand

- Confirm delivery timing so appliances arrive after carpentry, not before it is ready

- Keep the spec sheet or manual; installers and your carpenter both need the dimensions

How do appliance choices shape the kitchen carpentry itself?

Your appliance list quietly dictates the whole cabinet layout. An oven at eye level needs a tall housing unit; a dishwasher needs a cabinet-width gap with services behind it; a large fridge may need a taller ceiling clearance and a wider run of floor. Deciding these before design lock-in is exactly the kind of coordination that a proper kitchen renovation planning process is meant to handle, so the carpentry, worktop, tiling and wiring all reference the same appliance schedule.

When you plan your kitchen renovation, hand your contractor a single sheet listing every appliance, its dimensions, its power or plumbing needs and where it will sit. That one document keeps the carpenter, electrician, plumber and worktop fabricator working from the same source, and it is the cheapest insurance against a fridge that does not fit or an oven with no suitable point.

- Give the appliance schedule to your renovation contractor before design is finalised

- Coordinate hob cut-outs and cooker hood ducting with the carpentry drawings

- Confirm sink and tap models so the worktop cut-out and plumbing rough-in are correct

What clearances and ventilation should I plan for?

Every appliance needs breathing room and access. Fridges release heat and need a gap at the back and sides; ovens need ventilation so the surrounding cabinet does not overheat; a cooker hood needs the right distance above the hob to extract effectively. Doors and drawers also need to open fully without hitting an island or a neighbouring appliance.

In Singapore's humid climate, ventilation and moisture matter. Make sure your cooker hood ducting has a sensible path outdoors or to the designed exhaust, and keep the fridge away from direct afternoon sun where possible. Small clearance mistakes show up as doors that clash or an appliance that runs hot and loud.

Frequently asked questions

Should I buy kitchen appliances before or after renovation? Buy or at least fully confirm your major built-in appliances before the carpentry is built. Cabinets, worktop cut-outs, power points and plumbing are all built around the exact models, so choosing appliances first prevents expensive rework on finished cabinetry.

Do I need a dedicated power point for an oven or induction hob in Singapore? Often yes. Built-in ovens and induction hobs draw high power and may need a dedicated circuit rather than a shared 13-amp socket, with cable and breaker sized to match. Give the spec sheets to a licensed electrician before wiring is finalised so the points are rated and placed correctly.

Where do Singapore homeowners usually buy kitchen appliances? Common options include large retailers such as Courts, Harvey Norman, Gain City and Best Denki, plus brand showrooms and stores like IKEA. Compare the same model across a few sellers and confirm installation, delivery and warranty. Treat any price as a guide and check current pricing before buying.

Can I change my appliances after the kitchen is built? Free-standing, plug-in items like an air fryer or kettle can be swapped anytime. Built-in appliances are much harder, since a new model may not fit the existing opening or point. If you expect to upgrade later, tell your contractor early so the housing and services allow for it.
