What does it cost to build a separate wet kitchen in Malaysia?
A separate wet kitchen is a dedicated enclosed cooking zone built behind or alongside the main dry kitchen. It keeps wok-frying heat, steam and cooking odours out of the open-plan living and dry-kitchen area. In the Klang Valley, most terrace houses and many older condos are built with this in mind — either using a rear utility space, a converted yard area, or by partitioning the existing kitchen. Here are the broad 2026 cost ranges:
| Scope | What’s included | Indicative cost (Klang Valley) |
|---|
| Basic partition | Glass or aluminium partition across existing kitchen, ventilation grille, basic sink & tap | RM8,000 – RM15,000 |
| Mid-range build | New walled wet-kitchen room, full tiling, MR-plywood cabinets, hood & hob, plumbing & electrical | RM25,000 – RM40,000 |
| Premium extension | Rear-yard extension with structure, glass bifolds, custom cabinets, island prep counter, premium appliances | RM45,000 – RM70,000+ |
Note: these costs are for the wet kitchen build only. If you are also renovating the adjacent dry kitchen, see our kitchen renovation cost guide → for the dry-kitchen component.
Types of wet kitchen build in Malaysian homes
The right type of wet kitchen for your home depends on the existing layout and available space:
- Glass or aluminium partition across an open kitchen — the lowest-cost option. Creates a visual and partial odour barrier but is not fully enclosed. Best for condos and apartments with limited space. Cost: RM8,000–RM15,000 including ventilation improvements.
- Enclosed rear kitchen room using existing utility or bomb-shelter space — the most common approach in terrace houses. Requires hacking, new tiling, dedicated plumbing, a hood and proper ventilation to exterior. Cost: RM20,000–RM40,000 depending on size and finishes.
- Yard or rear-space conversion — enclosing an existing covered yard or rear service area to create a proper wet kitchen. May require a minor structure (polycarbonate/metal roof, walls, drainage). Cost: RM25,000–RM50,000 including structure.
- Rear extension build — a purpose-built addition to the rear of a landed property, typically requiring LA or council approval. Full brickwork/steel structure, new floor slab, full M&E. Cost: RM45,000–RM80,000+.
Wet kitchen build cost comparison
| Build type | Suitable for | Approval needed | Indicative cost |
|---|
| Glass/aluminium partition | Condo, apartment, small kitchen | Condo management consent | RM8,000 – RM15,000 |
| Enclosed rear kitchen room | Terrace house, semi-D | Usually none if within existing structure | RM20,000 – RM40,000 |
| Yard / service-area conversion | Landed property with covered rear yard | LA approval if structure added | RM25,000 – RM50,000 |
| Purpose-built rear extension | Semi-D, bungalow, link house | LA / MPAJ / MBPJ approval required | RM45,000 – RM80,000+ |
For any build that adds new structure to the exterior of a landed property, check with your local authority (LA) before proceeding. Unpermitted extensions can be ordered demolished at the owner’s cost. See our full house renovation cost guide → for broader context.
Cost breakdown by trade
For a typical mid-range enclosed wet kitchen (about 60–80 sq ft) in a Klang Valley terrace house:
| Trade / item | Typical share | Cost driver |
|---|
| Structural work (walls, floor, ceiling) | 15–25% | Extension vs. enclosure of existing space |
| Tiling (floor + full-height wall) | 15–20% | Tile grade and total area |
| Cabinets & worktop | 25–35% | Material: MR plywood vs. aluminium |
| Plumbing (sink, water points, drainage) | 10–15% | Distance from existing wet zone |
| Ventilation (hood, ducting, exhaust fan) | 8–12% | Ducting length and wall penetration |
| Electrical (new circuits, points, lighting) | 8–12% | Distance from DB; new sub-DB if far |
| Hacking, disposal & waterproofing | 5–10% | Wet floor must be waterproofed |
Cabinet & worktop options for the wet kitchen
Because the wet kitchen is exposed to constant steam, grease and high heat, material choice matters far more here than in the dry kitchen. Standard melamine will swell and delaminate within 2–3 years — this is the single most common costly mistake in wet kitchen builds:
| Material | Cost (per running ft) | Moisture resistance | Lifespan (wet environment) | Recommendation |
|---|
| Standard melamine | RM180 – RM320 | Poor — swells rapidly | 2–4 years | Do NOT use in wet kitchen |
| MR (moisture-resistant) plywood | RM350 – RM600 | Good | 10–15 years | Best value for wet kitchen |
| PVC / solid surface board | RM500 – RM850 | Very good | 12–20 years | Premium mid-tier |
| Aluminium frame cabinet | RM700 – RM1,300+ | Excellent — fully waterproof | 20+ years | Best long-term for wet kitchen |
For worktops, granite tiles are the budget choice (RM80–RM150/sq ft), quartz the mid-range standard (RM200–RM350/sq ft), and solid granite slab the premium option (RM350–RM600/sq ft). Avoid laminate worktops in the wet kitchen — the steam and grease environment causes edge swelling and delamination.
Structure & extension costs
If your wet kitchen build involves adding new structural elements — walls, a roof, a floor slab or a service yard enclosure — these are typically the biggest variables in the quote:
- Light steel or timber roof (polycarbonate/metal sheet): RM3,000–RM8,000 for a basic service-yard covering, depending on span and material.
- Brickwork wall (per linear metre): RM250–RM450/m including plaster and skim. A 4 m × 3 m enclosure requires roughly 14 linear metres of wall — approximately RM4,000–RM7,000.
- New floor slab (concrete, per sq ft): RM25–RM50/sq ft for a ground-floor slab, depending on thickness and reinforcement. A 60 sq ft wet kitchen slab costs RM1,500–RM3,000.
- Drainage and floor trap: RM600–RM1,500 for a new floor drain with proper gradient, essential in any wet kitchen.
Ventilation & extraction — the most overlooked cost
Proper ventilation is what separates a functional wet kitchen from one that fills the house with cooking fumes. In the Klang Valley climate, wok cooking at high heat generates significant grease-laden steam — an inadequate hood or blocked ducting causes grease to accumulate on walls and ceilings throughout the home:
- Standard chimney hood (60 cm): RM500–RM1,200 supply. Choose a minimum 800 m³/h extraction rate for wok cooking.
- Commercial-style hood (90 cm, 1,200+ m³/h): RM1,200–RM3,500 supply. Recommended for serious daily wok cooking.
- Ducting to exterior: RM800–RM2,500 depending on route length. Always duct to the exterior — never into a ceiling void or recirculate-only in the wet kitchen.
- Exhaust fan (wall or ceiling, backup): RM150–RM400 installed. Useful as a secondary ventilation point.
Budget at least RM1,500–RM4,000 for a properly designed ventilation system. Cutting this budget is the second most common expensive mistake after using the wrong cabinet material.
What affects your wet kitchen build cost the most?
Four factors move the price more than anything else:
- Whether you need new structure. Building new walls, a slab or a roof can add RM10,000–RM30,000 to a job that would otherwise be primarily M&E and fit-out. Working within the existing building envelope is significantly cheaper.
- Cabinet material. The gap between melamine and aluminium-frame cabinets can be RM200–RM1,000 per running foot. For a 10 ft run, that is RM2,000–RM10,000 of difference.
- Distance from existing plumbing and electrical. If the wet kitchen is near the existing water points and distribution board, routing is quick and cheap. If it is at the opposite end of the house, expect long pipe runs and new conduit — adding RM3,000–RM8,000.
- Whether LA approval is required. A permitted rear extension adds design fees (RM3,000–RM8,000), approval fees and compliance costs that can total RM10,000–RM20,000 on top of construction.
Worked example: mid-range wet kitchen build in a KL terrace house
An illustrative budget for converting a covered rear service yard (~70 sq ft) in a Klang Valley terrace house into an enclosed mid-range wet kitchen. Treat this as a planning guide, not a quote:
| Item | Indicative cost | Notes |
|---|
| Enclose rear yard (brickwork + simple roof) | RM10,000 | ~4 m × 3 m space, steel roof |
| Floor screed, waterproofing & drain | RM3,000 | New floor slab + membrane |
| Full-height wall & floor tiling | RM6,000 | Mid-range 30×60 tiles, ~60 sq m total |
| MR-plywood cabinets (12 running ft) | RM6,500 | Upper + lower run |
| Granite tile worktop | RM1,800 | ~12 sq ft |
| Hood (90 cm) + ducting to exterior | RM3,000 | 800 m³/h hood + 3 m duct run |
| Plumbing (sink, tap, water points) | RM2,500 | New run from existing wet zone |
| Electrical (new points, lighting, exhaust) | RM2,000 | 2 double sockets + LED lighting |
| Hacking, disposal & misc. | RM2,000 | |
| Total | ~RM36,800 | Mid-range finishes, existing space |
A basic glass-partition approach in a condo could cost as little as RM8,000–RM12,000. A premium purpose-built extension with bifold glass doors and aluminium cabinets could reach RM60,000–RM80,000+.

How to save without cutting corners
- Work within the existing building envelope. If there is an existing covered service yard or rear utility room that can be enclosed and tiled, avoid adding new structure. This alone saves RM10,000–RM25,000.
- Keep plumbing close to the existing wet zone. Minimising pipe runs by siting the new wet kitchen near existing water points reduces M&E costs significantly.
- Use MR-plywood cabinets, not aluminium. MR-ply delivers 90% of the moisture protection at roughly 50% of the cost. Aluminium is a long-term upgrade, but not essential for a first build.
- Size the hood correctly from the start. Do not under-spec ventilation to save RM500 — the grease remediation and repainting costs later will far exceed the saving.
- Bundle with the dry kitchen or wider renovation. Running the wet kitchen alongside a broader renovation shares haulage, labour mobilisation and supervision costs.
- Get three itemised quotes with comparable scope before committing. A lump-sum quote is impossible to compare meaningfully.
How to choose a contractor for your wet kitchen build
- Ask for an itemised quotation that separates structural, tiling, cabinets, plumbing, electrical and ventilation. A lump sum prevents you from identifying where costs differ between quotes.
- Confirm the contractor specifies MR-plywood (or better) for all wet-zone cabinets in writing — not just verbally.
- Check they design the ventilation duct to exterior — not to a ceiling void or recirculation-only mode.
- Verify experience with structural enclosures if the job involves new walls or a roof — not all renovation contractors handle this.
- Confirm waterproofing of the wet kitchen floor is included, with a written warranty.
- Agree a milestone payment schedule (deposit, structural completion, fit-out completion, final snag) rather than paying everything upfront.

Common wet kitchen build mistakes to avoid
- Using standard melamine cabinets in the wet kitchen — the single most common, most regretted mistake. Steam and grease swell melamine boards within 2–3 years, leading to sagging doors and a full replacement bill.
- Recirculating the hood exhaust into the ceiling — grease accumulates in the void, becomes a fire hazard, and eventually finds its way into the house. Always duct to exterior.
- Skipping the floor waterproofing membrane — a wet kitchen floor that is not properly waterproofed will seep water into the slab, causing costly structural damage and ceiling stains to rooms or areas below.
- Under-sizing the hood — a hood with insufficient extraction capacity (below 600 m³/h) will fail to clear wok fumes, defeating the entire purpose of a separate wet kitchen.
- Building without LA approval for a new structural extension — an enforcement notice can result in a mandatory demolition order at your cost. Always check with your local council first.
- No contingency budget — wet kitchen builds often reveal hidden drainage issues, old corroded pipes or unexpected structural problems once hacking starts. Allow 10–15% for surprises.
How long does a wet kitchen build take?
Timeline depends heavily on whether new structure is required. For a typical mid-range terrace-house enclosed wet kitchen:
- Week 1: Hacking, site clearance, new brickwork or framing (if applicable).
- Week 1–2: Rough-in plumbing, electrical conduit, waterproofing of floor.
- Week 2–3: Plastering, floor and wall tiling.
- Week 3–4: Cabinet fabrication and installation, worktop templating.
- Week 4: Worktop, hood, hob, ducting, electrical fixtures, final plumbing connections.
- Week 4–5: Snag, silicone sealing, cleaning and handover.
A pure partition job (no new structure) can be completed in 1–2 weeks. A purpose-built extension requiring LA approval adds 4–8 weeks to the timeline for the approval process alone.
