Wet and dry kitchen design for Malaysian homes

The wet-and-dry kitchen is a genuinely good climate and cooking response, and it is also frequently built when it is not needed — because it appears on every developer floor plan.

Whether you need one depends entirely on how you cook.

Why the split exists

Wok cooking at high heat aerosolises oil. That vapour condenses on every surface it reaches, and no domestic extraction hood captures all of it. Over a few years it builds a film on cabinet doors, ceilings and the underside of wall units.

The wet kitchen isolates that. It is a sealed or semi-sealed room with heavy-duty extraction, hard finishes and a floor that can be hosed. The dry kitchen — often open to the living area — handles preparation, coffee, breakfast and everything that produces no grease.

The split makes sense if you wok-fry regularly. If your household cooks mostly Western, uses an induction hob, or eats out five nights a week, a second kitchen consumes floor area and budget for a room that becomes storage within a year.

A practical test: count the times last month you cooked something that filled the kitchen with vapour. Fewer than four, and a single well-ventilated kitchen with a properly sized hood is the better answer.

Extraction: the decision everything else depends on

Get this wrong and nothing else in the kitchen matters.

• Wok cooking: an extraction rate of at least 1,000 m³/h, ducted externally. Chinese-style hoods with high suction outperform slimline European designs for this task, whatever the showroom says.
• Standard cooking: 600–800 m³/h is adequate.
• Always duct outside. Recirculating hoods with charcoal filters remove some odour and essentially no grease or moisture. In this climate that is not a compromise, it is a failure.
• Duct run: keep it short and straight. Every bend costs performance; a long flexible duct with three bends can halve effective airflow.
• Make-up air: a powerful hood needs air to replace what it removes. In a sealed, air-conditioned kitchen a strong hood will simply starve. Provide a vent or leave a door undercut.

Layout

The work triangle — sink, hob, refrigerator — still governs. Keep the sum of the three legs between roughly 4m and 7m. Larger and you walk too far; smaller and two people cannot work without collision.

Galley suits narrow plans and wet kitchens. Two parallel runs, 1,000–1,200mm apart.

L-shape is the most flexible for dry kitchens, and leaves a corner for a table.

Island needs a room at least 3.6m wide to leave 900mm clear on all sides. Below that it becomes an obstacle. Islands are also the most common thing we remove from a first-draft layout, because in most Malaysian apartments the same money buys better storage elsewhere. Kopi Lane is a commercial example of the opposite decision — there the island had to wrap a structural column, and that constraint improved it.

Dimensions worth setting yourself

Catalogue standards were set for a different average height.

• Worktop height: the usual 850mm suits someone around 165–170cm. The comfortable rule is elbow height minus 100–150mm. For a cook of 155cm, 800mm is far better — and a different height for the wok station is normal, since wok work is done lower.
• Upper cabinet clearance: 500–600mm above the worktop. Less and you knock your head; more and the top shelf is unreachable.
• Walkway: 900mm minimum single-cook, 1,200mm if two people cook together.
• Drawer over door: deep drawers in base units beat cupboards for almost every purpose. The rear of a base cupboard is where things go to be forgotten.

Worktops

For a wet kitchen, granite or stainless steel. For a dry kitchen, quartz is the sensible default.

Details that matter in this climate

• Ventilation gap behind base units on external walls, to stop condensation building where you cannot see it.
• Marine plywood or aluminium carcasses under the sink, without exception — see materials for Malaysian humidity.
• A slight fall on the wet kitchen floor toward a floor waste, so it can genuinely be washed down.
• Sealed skirting or a coved junction at the floor, so grease and water have nowhere to collect.
• Task lighting under wall units. Ceiling downlights put your own shadow on the worktop, which is the most common lighting complaint we hear.
• Sockets where they are used, not evenly spaced. Map your appliances first.

A common sequence error

Kitchens are often designed around a cabinet layout, then extraction is added at the end. Reverse it: decide how you cook, size the extraction, place the hob where the duct can run short and straight, and build the layout around that.

A kitchen with a beautiful layout and a starved hood becomes a kitchen nobody cooks in. Our kitchen and joinery service starts with the cooking, and the drawings follow.
