Kitchen renovation: a straight answer from a main contractor

Your kitchen is where renovation mistakes show up fastest. Doors clash, sockets end up behind appliances, the sink is too near the hob, and the quote you thought was complete suddenly is not. A singapore kitchen renovation goes better when you treat it like a build, not just a mood board.

That is the straight answer from a main contractor. Before choosing colours or handles, decide the scope, the constraints, and the service runs. Service runs means the water pipes, waste pipe, gas line, power points and hood exhaust path. Those decide more than most owners expect.

What a kitchen renovation usually costs in Singapore

For 2026, the common ranges for an HDB kitchen in Singapore are roughly these:

• Basic refresh: about S$8,000 to S$15,000. This usually means simple carpentry, basic finishes, limited electrical or plumbing changes, and no major layout change.
• Standard full renovation: about S$15,000 to S$25,000. This is where many complete HDB kitchens land. New cabinets, new worktop, sink and mixer, backsplash, moderate electrical and plumbing works.
• Premium or heavy overhaul: about S$25,000 to S$35,000+. More hacking, more tiling, premium stone, built-ins, island work, or open kitchen conversion.

Many complete HDB kitchens end up around S$18,000 to S$25,000. That is not a promise. It is a realistic middle band if you are changing most of the kitchen but not rebuilding half the flat.

What moves the number:

• How much carpentry you are building.
• Whether you hack tiles and walls.
• Whether you move the sink, hob or gas point.
• Countertop material and length.
• How many new power points, light points and dedicated circuits you need.
• Appliance type, freestanding versus built-in.
• Property type: HDB, resale, BTO, condo.
• Site condition: old pipes, uneven walls, hidden defects.

If you only remember one thing about kitchen cost, remember this: carpentry usually carries the budget. Not the nice tap, not the pendant light, not the handle colour. Cabinet length, cabinet height, drawer count, internal accessories, carcass material and laminate grade add up quickly.

A practical cost breakdown

Not every project uses the same line items, but these are the usual buckets:

Work item	Typical effect on budget	What increases cost
Carpentry	Often the largest share	Full-height units, many drawers, corner systems, internal organisers, better board and laminate choices
Countertop	Moderate to high	Quartz, sintered stone, long runs, waterfall ends, cut-outs and unusual profiles
Hacking and disposal	Moderate	Removing wall tiles, floor tiles, old cabinets, masonry bases, and any approved wall removal
Tiling	Moderate to high	Large tile format, difficult laying, many corners, floor levelling, premium tiles
Plumbing	Low to moderate	Moving sink position, replacing concealed pipe sections, adding water points
Electrical	Low to moderate	More socket points, oven or hob loads, under-cabinet lighting, rewiring old circuits
Appliances	Wide range	Built-in oven, induction hob, hood, dishwasher, premium brands

The trade-off is simple. If you want the budget under control, reduce customisation first. Do not start by cutting the hidden work. Cheap hinges can be changed later. A badly planned sink trap or under-sized circuit is a nuisance every day.

What you are really paying for in a singapore kitchen renovation

Homeowners often think they are buying cabinets and a counter. In reality, you are paying for six things at once:

1. Layout planning. Where the work zones sit, and whether they can work with existing services.
2. Demolition and making good. Removing old finishes without damaging what stays.
3. Service coordination. Water, waste, gas and power must match the cabinet and appliance plan.
4. Fabrication. Cabinets, stone tops, glass or tile backsplash, metal support if needed.
5. Installation. This is where workmanship shows. Alignment, clearances, sealant, levelling.
6. Defect handling. Doors settling, silicone touch-up, appliance fit issues, concealed leak checks.

This matters because different firms are stronger at different stages. A design-first firm may produce nicer drawings. A build-first firm usually sees clashes earlier. If the same side handles both, there is less finger-pointing when the hood duct route steals your top cabinet space.

Start with scope: refresh, rebuild, or reconfigure

Most kitchen jobs fall into three types. Be honest about which one yours is.

1. Refresh

You keep the basic layout. You may replace cabinet shutters, countertop, sink, tap, backsplash, and maybe some appliances. You do little or no tile hacking. This is the cheapest route and often the fastest.

Best for: newer flats, decent existing layout, tight budget.

Trade-off: you save money, but you also keep old service positions and old planning mistakes.

2. Rebuild in the same footprint

You remove the old kitchen and build a new one in roughly the same positions. Sink stays near sink. Hob stays near hob. You may retile and rewire parts of the space, but you do not fight the building too much.

Best for: most owners. This is where many S$15,000 to S$25,000 kitchens sit.

Trade-off: you get a full visual and functional reset, but not complete freedom.

3. Reconfigure

You move zones, open up walls where approval allows, add an island or peninsula, hide appliances, or convert from enclosed to open concept.

Best for: owners who cook often and know exactly what is wrong with the current plan.

Trade-off: highest cost, more approval risk, more hidden work, longer programme.

A lot of kitchen overspending happens because the owner says "simple only" but the scope is actually a reconfiguration. Once you move the sink and hob, "simple" is usually gone.

Layout first, style second

A kitchen that looks good but works badly is expensive storage. Before material choices, settle these questions:

• How many people cook at one time.
• How often you fry, boil, bake or meal prep.
• Whether you need a dishwasher, tall oven, or full-sized fridge.
• Whether small appliances stay out or go into cabinets.
• How much dry storage you really use.
• Whether you need a separate service yard workflow.

Then look at the three main zones:

1. Storage zone: fridge, dry goods, crockery.
2. Wash zone: sink, dish rack, bin, detergent, dishwasher if any.
3. Cook zone: hob, hood, oils, spices, utensils, oven if any.

Good kitchens reduce crossing. You should not carry dripping vegetables across the hob area to wash them. You should not put the fridge where its door blocks the main walkway. You should not place the bin so far from the prep area that scraps end up on the floor.

Common planning mistakes

• Top cabinets too low, head hits while washing.
• Fridge door cannot open fully because of wall return or handle clash.
• Drawer bank placed where another door blocks it.
• Microwave niche with no ventilation allowance.
• Hood duct route not planned before carpentry measurement.
• Too few sockets on the worktop run.
• Sink too small for woks and oven trays.
• Worktop joints placed at obvious wet areas.

These are not design theory issues. They are site issues. They should be checked against appliance models, actual wall dimensions, and service points before fabrication.

Materials: where to spend, where to save

You do not need the most expensive finish for a durable kitchen. You need suitable materials in the right places.

Cabinet carcass and fronts

The carcass is the cabinet box. The shutters are the doors and drawer fronts. Ask what board is used, what finish is used, and what edge treatment is provided. Water resistance matters most near sink areas and floor-level cabinets.

Spend more if: your kitchen is heavily used, you want more drawers, or you need full-height storage that stays straight and stable.

Save money by: reducing special internal accessories, limiting glass doors, avoiding too many narrow custom modules.

Countertops

Countertops need to handle heat, moisture, impact and staining. Different materials perform differently. No material is perfect.

Material	Typical strength	Typical compromise
Laminate top	Lower upfront cost	Less resistant to heat and wear
Solid surface	Can have cleaner-looking joints, easy to shape	Can scratch and has heat limits
Quartz	Popular balance of look and durability	Costs more than budget options, still needs proper use
Sintered stone or natural stone	Premium appearance, strong performance depending on product	Higher cost, heavier, detail planning matters

If the budget is tight, many owners get better value from a sensible quartz top and better drawer hardware, instead of stretching for a premium stone while cutting functional items elsewhere.

Backsplash and wall finish

Tiles are durable and practical. Glass can be easy to wipe but needs careful templating. Compact wall panels reduce grout lines but depend on the system used. If you fry often, choose based on cleaning, not just appearance.

Flooring

If the existing kitchen floor is sound and your new design can work with it, keeping it can save real money. If the floor is hollow, badly levelled, or does not match threshold heights after hacking, replacing it may be the correct decision.

The trade-off is cost versus disruption. Floor hacking means more noise, more debris, and more risk of uncovering uneven substrate that needs rectification.

HDB and condo constraints you should know before drawing anything

Rules matter most when owners want an open kitchen, move wet areas, or alter walls. The exact permission route depends on the property type and scope. For HDB flats, renovation rules and permit requirements apply to certain works such as hacking and works affecting services. For condos, there are also MCST rules on deposits, work hours, protection and submissions.

The practical point is this: do not design first and ask about approvals later. If the concept depends on removing a wall, moving a gas point, or changing wet area finishes, check feasibility early.

What usually needs extra care

• Hacking walls or floor finishes.
• Open-concept conversion.
• Gas pipe alteration.
• Changes affecting waterproofing at wet areas.
• Condo work hours, lift protection and debris disposal routes.

Also note the plain site reality. Older resale kitchens often hide surprises: patched pipes, uneven wall faces, abandoned points, non-standard levels. BTO kitchens usually have fewer legacy issues, but not always better layouts.

Electrical and plumbing: the hidden part that decides whether the kitchen works

Most owners under-plan this section. Then they live with extension cords, exposed hoses and awkward sink cabinets.

Electrical

Make a list of every powered item:

• Fridge
• Hob if induction
• Hood
• Oven
• Microwave
• Dishwasher
• Water dispenser or purifier
• Rice cooker, kettle, toaster, coffee machine
• Under-cabinet lights

Then mark what stays plugged in all the time, what is built in, and what sits on the worktop. Some appliances need dedicated planning for load and location. Even when the cost of adding points looks small on paper, the right number and placement can change daily convenience a lot.

Plumbing

The sink location affects waste pipe routing, trap space, dishwasher position and base cabinet use. If you move the sink too far from the existing discharge point, you may lose storage because the pipe fall has to be maintained. Pipe fall means the slight slope needed for wastewater to drain properly.

That is why a perfectly symmetrical drawing can still be a poor build decision. The services may not support it without compromise.

Gas

If you use gas, treat gas line changes seriously. The route, clearances and compliance matter. Plan the hob model early. Do not assume any cabinet layout can simply "hide" the pipe neatly.

Open kitchen, enclosed kitchen, or half-open

This is one of the biggest decisions in a singapore kitchen renovation. It affects cost, approvals, smell control, storage and resale appeal.

Open kitchen

Pros: brighter feel, more interaction with living area, room for island or peninsula if space allows.

Cons: more visible clutter, smell and grease spread more easily, usually higher cost if hacking is involved.

Enclosed kitchen

Pros: better containment for heavy cooking, more wall space for storage, easier to keep the mess out of sight.

Cons: can feel smaller and darker if not planned well.

Half-open kitchen

Pros: some visual openness without fully giving up separation, can work with sliders, windows or a partial wall.

Cons: detailing becomes more important, and partial solutions can look unresolved if done carelessly.

For families who cook often with oil and strong seasoning, enclosed or half-open usually ages better in daily use. For light cooking, open kitchens can work well. This is not about taste. It is about actual cooking habits.

Timeline: what takes time, and what causes delay

A kitchen renovation is not only site work. It includes measuring, drawing, confirmation, procurement and fabrication. The exact duration depends on scope, approvals and how quickly selections are confirmed.

What usually stretches the programme:

• Late appliance selection, which affects cabinet dimensions.
• Change of layout after hacking starts.
• Wall or floor conditions that need rectification.
• Approval lead times where required.
• Countertop templating delays because base cabinets are not ready.

A common sequence is: site measure, drawing confirmation, demolition, service works, wet works, cabinet measurement or installation depending on method, top templating, countertop install, final fittings, testing and defects.

The straight trade-off is this. Fast jobs need early decisions. If you want to compare six hob models, three sink types and four laminates after site work starts, the programme will move with that.

How to read a kitchen quotation without getting lost

A short quote can look cheap because it says less. A longer quote can look expensive because it names more things. Do not compare only the total.

Check whether these are clearly stated:

• Demolition scope and debris disposal.
• Whether floor and wall tile hacking are included.
• Whether haulage or protection is included if relevant.
• Cabinet carcass material, finish and internal colour.
• Door and drawer hardware specification.
• Countertop material and thickness.
• Backsplash material and height.
• Number and type of electrical points.
• Plumbing inclusions and exclusions.
• Appliance installation scope.
• Painting or making good to adjacent areas.
• Permit or submission responsibilities where applicable.

Two quotes with the same total can be very different jobs. One may include tile replacement, service alteration and haulage. Another may price only carpentry and top, leaving the rest as variation later.

Good questions to ask

1. What assumptions are you making about existing pipes, walls and levels?
2. What is excluded because it cannot be confirmed yet?
3. If I change sink or hob position, what else is likely to change?
4. When do appliance models need to be confirmed?
5. What on-site conditions commonly create variation for this type of kitchen?

Those questions are more useful than asking only for a discount.

Where owners usually overspend, and where they regret cutting

Common overspends

• Too many internal accessories that do not match actual use.
• Fancy finishes on cabinets that are exposed to heavy wear.
• Premium stone on a small kitchen while storage remains badly planned.
• Oversized islands in spaces that need better clearance instead.

Common regrets from over-cutting

• Too few drawers.
• Too few sockets.
• Weak task lighting.
• Low-quality runners and hinges on heavily used cabinets.
• Not planning for bin, cleaning items and dish drying from the start.

If you want a practical rule, spend on the parts you touch every day: drawer systems, worktop usability, sink size, lighting, socket placement and service planning.

Who a main contractor suits best

Not every homeowner needs the same setup. If you already have a complete design and only need build execution, your priority may be coordination and workmanship. If you have no drawings and no renovation experience, you need both planning and build sense.

A direct main contractor approach suits owners who want the design to answer to the build. It is useful when the kitchen has real trade coordination issues, not just decorative ones. The advantage is not magic. It is fewer gaps between what is drawn and what can be installed by the crew on site.

The trade-off is also plain. Build-led teams may be more direct and less theatrical in presentation. If you value that, good. If you want ten mood boards before discussing the waste pipe route, that is a different process.

FAQ

How much should I budget for a complete HDB kitchen renovation?

A realistic 2026 budget for many complete HDB kitchens is around S$18,000 to S$25,000. A basic refresh may be around S$8,000 to S$15,000, while heavier or more premium builds can run S$25,000 to S$35,000 or more. The main cost drivers are carpentry volume, countertop choice, hacking, tiling, and whether you move plumbing, gas or electrical points.

Is it cheaper to keep the existing kitchen layout?

Usually yes. Keeping the sink, hob and main service positions reduces plumbing, electrical and gas changes. It also lowers the chance of site complications. The trade-off is that you may keep some functional weaknesses of the old kitchen. For many homes, rebuilding within the same footprint gives the best balance of cost and improvement.

Should I hack the kitchen wall to create an open concept?

Only if the space and your cooking habits support it, and only after checking whether the wall can be altered and what approvals are needed. Open kitchens can make the home feel larger, but they usually cost more and contain cooking smells less well. For heavy cooking, a half-open or enclosed kitchen is often the more practical choice.
