How much does a wet kitchen and dry kitchen renovation cost in Penang?

A typical Penang home splits its kitchen budget into roughly RM 12,000 to RM 35,000 for the dry kitchen and RM 6,000 to RM 20,000 for the wet kitchen, and mixing up which zone needs which materials is the most common costly mistake we see in quotes on this directory. Most Malaysian homes run two kitchens under one roof rather than one: a dry kitchen for display, coffee, and light meals, and a wet kitchen for the heavy wok cooking that would otherwise wreck the finishes in the "good" kitchen. This guide explains what belongs in each zone, what materials actually hold up there, and how the two budgets sit against the overall kitchen renovation cost bands we track for George Town.

What "wet kitchen" and "dry kitchen" actually mean

A dry kitchen is the kitchen you show people. It usually sits closer to the living and dining area, sometimes fully open-plan, and is used for coffee, toast, reheating, the occasional stir-fry on an induction hob, and storing crockery. It gets the nicer finishes because it stays relatively clean: laminate or plywood cabinetry, a display island or peninsula, pendant lighting, and a countertop chosen as much for looks as durability.

A wet kitchen is where the real cooking happens: wok frying, deep frying, steaming, boiling, and the kind of high-heat, high-oil cooking common in Chinese, Nyonya, and Indian home cooking. It is usually tucked at the rear of a terrace house, in a semi-outdoor space, or behind a service yard door in a condo. It gets built with materials that shrug off oil splatter, steam, and strong smells rather than materials that photograph well.

The split exists because Penang's everyday cooking is genuinely hard on a kitchen. A few nights of belacan, curry, and wok-fried noodles leave oil film and lingering smell that a display kitchen's laminate finish and open-plan layout were never designed to absorb. Separating the two lets the dry kitchen stay presentable while the wet kitchen absorbs the abuse, and it is one reason renovation quotes in Penang so often list two kitchen scopes rather than one.

Splitting the budget: dry kitchen vs wet kitchen

These are the typical scopes and material choices we see in quotes that separate the two zones, alongside what a project costs when both are handled together.

Zone	Typical scope	Material	RM range
Dry kitchen	Display cabinetry, sink, induction or electric hob, coffee and prep counter, sometimes an island	Laminate/melamine or plywood carcass, quartz or solid-surface countertop	RM 12,000-35,000
Wet kitchen	Wok burner, extraction hood, washing point, pot and ingredient storage	Aluminium or stainless steel cabinets, tiled or quartz countertop	RM 6,000-20,000
Combined renovation (typical terrace or condo)	Both zones handled as one project, no structural changes	Mixed material by zone	RM 18,000-55,000
Combined with structural work (adding or enclosing a wet kitchen)	Both zones plus an extension, roofing, or enclosure	Mixed material by zone, plus structural works	RM 30,000-70,000+

The "combined renovation" row lines up with Band 1 and Band 2 of our general kitchen renovation cost guide: most homes doing a standard kitchen job are really funding both zones out of one number, they just don't see it broken out unless they ask. Once you add demolition, wall hacking, rewiring, and new flooring across the whole kitchen footprint, a project moves into Band 3 territory (RM 55,000-90,000) regardless of the wet/dry split, because those costs apply to the room as a whole, not to one zone.

Dry kitchen materials and costs by tier

Dry kitchen cabinetry is priced per linear foot, the same way built-in wardrobes are, and the logic is nearly identical: carcass material is the dominant cost driver, then countertop, then hardware.

Tier	Per linear foot	Typical 10-foot run
Laminate/melamine carcass	RM 750-1,100	RM 7,500-11,000
Plywood carcass, upgraded finish	RM 1,100-1,600	RM 11,000-16,000
Quartz countertop add-on	RM 280-450 per linear foot	RM 2,800-4,500
Island or peninsula addition	RM 3,500-9,000	flat, size-dependent

A dry kitchen with a 10-foot run, a quartz countertop, and a small island typically lands in the RM 18,000-28,000 range, which is why it eats most of the RM 12,000-35,000 band on its own before the wet kitchen is even quoted. Melamine is fine for a dry kitchen because it rarely sees direct heat or heavy moisture; plywood earns its premium mainly in humid corners or where the dry kitchen backs onto an external wall.

Wet kitchen materials and costs by tier

Wet kitchen cabinetry trades finish for durability. Aluminium and stainless steel dominate this zone because both shrug off oil, steam, and the occasional water splash in a way laminate and particleboard cannot.

Material	Per linear foot	Typical 8-foot run
Aluminium frame cabinet, laminate or PVC panel infill	RM 450-750	RM 3,600-6,000
Stainless steel cabinet, welded construction	RM 750-1,200	RM 6,000-9,600
Tiled countertop (ceramic or homogeneous tile)	RM 45-80 per square foot	site-measured
Quartz countertop, wet-kitchen grade	RM 250-380 per linear foot	RM 2,000-3,000

Aluminium cabinetry is the more common choice for domestic wet kitchens in Penang: it costs less than a comparable stainless run, resists rust in a humid, splash-prone environment, and is easy to wipe down. Stainless steel costs more because the panels are usually welded rather than framed, but it holds up better against direct heat near a high-BTU wok burner and against sharp-edged cookware, which is why it shows up more often in homes that cook commercial-style volumes or run a food business out of the house.

Ventilation and exhaust for the wet kitchen

A wet kitchen lives or dies on how well it clears smoke, steam, and oil vapour. Two things matter here:

1. A properly ducted hood, not a recirculating one. A wall-mounted or ceiling hood ducted straight to an external wall or the outside typically costs RM 800-2,500 installed, depending on CFM rating and duct run length. A recirculating hood that just filters and blows air back into the room is cheaper but leaves oil film in the air, which is exactly what a wet kitchen is meant to avoid.
2. Cross ventilation from an actual opening. Most well-built Penang wet kitchens keep a window, louvre panel, or a section left open to the sky so heat and steam can escape naturally rather than relying on the hood alone. If you're adding or replacing that opening, an aluminium casement or louvre window is priced the same way as any other aluminium window in the house, see our aluminium works cost guide for panel pricing by size and glass grade.

Condo owners enclosing a service yard into a wet kitchen should also check whether the management corporation allows a ducted external vent through the facade; some strata buildings restrict facade penetrations, which pushes owners toward a recirculating hood plus a louvre door instead.

Waterproofing and floor falls in the wet zone

Because a wet kitchen involves direct water use (washing vegetables, rinsing woks, mopping down oil splashes), the floor and drainage detailing matters more here than anywhere else in the house.

• Floor fall towards a drain point. The tiler should slope the floor at roughly 1:100 to 1:200 towards a floor trap, so standing water clears on its own instead of pooling near the cabinet base.
• Waterproofing membrane under the tile, run up the wall at least 150-300mm at the skirting and higher behind the sink and wok station. This is a small line item, typically RM 8-15 per square foot, but it is the one step that prevents seepage into the dry kitchen or, in a condo, into the unit below.
• A step-down of 20-50mm from the dry kitchen into the wet kitchen is common in terrace houses specifically to contain splashes and stop water migrating into the display zone.
• Non-slip, matte-finish tile (R10 slip rating or better) rather than the polished porcelain often used in the dry kitchen, since the wet kitchen floor is wet more often than not.

Skipping any of these to save a few hundred ringgit is the single biggest source of "why is my dry kitchen floor damp" complaints we hear about after a renovation.

Adding a wet kitchen where there isn't one

Plenty of Penang condos and older single-storey terraces were built with only one small kitchen and no separate wet zone at all. Adding one later is a common request, and the cost depends heavily on whether it's structural.

In a condo, the usual move is enclosing the service yard or utility balcony behind the kitchen into a proper wet kitchen. Before doing this, confirm with the joint management body whether structural changes, gas cylinder storage, and facade penetrations (for ducting or a window) are permitted; many strata buildings prohibit piped or cylinder gas on an enclosed balcony, which pushes owners toward an induction wok burner instead of an open-flame one. Enclosing the space (glass or aluminium panel wall, basic tiling, cabinetry, and an extraction fan) typically runs RM 8,000-18,000 depending on the size of the yard and whether plumbing needs extending.

In a terrace house, adding a wet kitchen usually means extending into the rear yard or building under an existing awning. This needs MBPP or MPSP planning approval if the footprint extends beyond the original building line, plus a drainage tie-in to the existing sewer line and new roofing. A modest rear extension with basic aluminium or stainless cabinetry, tiling, and roofing typically lands between RM 15,000 and RM 30,000 before council fees, more if the extension needs a new roof structure rather than tying into an existing overhang.

How to brief your cabinet maker

A wet/dry split is easy to under-specify because it looks like one kitchen job on paper. Before getting quotes, write down:

1. Material by zone, named explicitly. "Kitchen cabinets" on a quote tells you nothing; ask for aluminium, stainless steel, laminate, or plywood, per zone, in writing.
2. Wok burner type and BTU rating, since a high-output burner needs a reinforced or heat-resistant countertop cutout, not just any quartz slab.
3. Hood CFM and duct route, confirmed before the ceiling or wall is closed up, not after.
4. Floor trap location and slope direction, agreed with the tiler before any tile goes down, since it cannot be corrected afterward without re-tiling.
5. Splashback material for the grease zone. Tile is standard; a stainless steel sheet behind the wok station is a common upgrade that resists staining better than grouted tile.
6. Gas cylinder storage, ventilated per Bomba guidance if you're keeping a cylinder rather than piped gas or induction.
7. Electrical points for both zones separately: small-appliance sockets in the dry kitchen, and burner ignition, exhaust fan, and water heater points in the wet kitchen.

Get three quotes against the same written spec, the same advice as in our general kitchen renovation cost guide, since a wet/dry split is one of the easiest places for a vague quote to quietly downgrade material after the contract is signed.
