Wet Kitchen vs Dry Kitchen in Malaysia: Layouts, Rules and What to Check in JB Homes

中文 · Bahasa Melayu · Bahasa Indonesia

In Malaysia, a wet kitchen (dapur basah) is the closed, washable room for heavy cooking such as frying, curries and sambal, and a dry kitchen (dapur kering) is the cleaner, often open area for light cooking, drinks and serving. You need both only if you cook often with strong heat, oil and spices. Landed extensions need council approval, condo kitchen works need the management’s written approval, and gas work needs a competent person.

What a wet kitchen and a dry kitchen are

The names describe how each space is used, not a legal category. Floor plans label them as “kitchen” and “dry kitchen”, “wet kitchen” and “pantry”, or one “kitchen” with a yard behind it.

	Wet kitchen (dapur basah)	Dry kitchen (dapur kering)
Typical use	Stir-frying, deep-frying, curries, sambal, washing fish and meat	Breakfast, drinks, reheating, baking, plating food
Position	Enclosed room at the back, next to the yard	Open to the dining area, often with an island
Appliances	Gas hob, heavy-duty hood, sink, floor trap	Induction hob, oven, microwave, fridge
Benefit	Smoke, grease and smells stay out of the house	Looks clean and sociable
Drawback	Takes floor area; hot without good ventilation	Not built for heavy cooking

Why so many Malaysian homes have two kitchens

Much home cooking across Malaysia’s communities uses high heat, oil and strong aromatics: wok frying, frying chilli paste, tempering spices and deep-frying fish. That means smoke, grease on walls and smells that linger in curtains and sofas. As open-plan condos became common, many households kept a closed room for that cooking and an open counter for everything else. In JB’s warm, humid climate, a wet kitchen with a window or an opening to the yard also lets heat out.

If your household cooks for a big family, entertains at festivals or needs separate preparation areas, two zones make daily life easier. My guides to Muslim-friendly living, the Indian community and Chinese-speaking life in JB cover food and daily life.

Common kitchen layouts in Johor homes

Home type	Usual arrangement	What to look out for
Terrace and semi-D houses	Dry kitchen inside; wet kitchen at the back, designed in or added later as an extension	Whether the rear kitchen is on the approved plan; leaks where the new roof meets the old
Larger condos	Open dry kitchen plus an enclosed wet kitchen beside the yard, sometimes with a glass door between	Where the hood vents; where the gas point is; whether the yard is also the laundry area
Mid-size condos	One enclosed kitchen with a yard, or a fully open kitchen	Whether the management allows a glass partition
Studios and serviced apartments	Open kitchenette, often with an electric hob only	Whether heavy cooking is practical; house rules on gas

Read the kitchen together with the yard, windows and aircon ledges: see floor plan red flags, built-up vs land area and landed house types.

Wet kitchen vs dry kitchen vs one kitchen: which suits you?

Your household	Usually works well	Why
Cooks heavy meals most days, larger family	Separate wet and dry kitchens	Smoke stays in one washable room; two people can cook at once
Cooks a few times a week	One kitchen with a ducted hood	Saves floor area for living space
Rarely cooks	Open dry kitchen or kitchenette	Cheaper to fit out; feels bigger
Landlord	Keep a closed kitchen if the layout has one	Families who cook often look for one; singles care more about furnishing

Landlords can see furnished vs unfurnished rentals for what tenants expect in the kitchen.

The rules that apply to kitchen works

Building by-law minimums

Kitchens are designed to the Uniform Building By-Laws 1984 (Undang-Undang Kecil Bangunan Seragam):

• Size and height: at least 4.5 m² and 1.5 m wide (by-law 42(3)), and at least 2.25 m high in homes other than shophouses (by-law 44(1)(b)).
• Light and air: windows of at least 10% of the floor area and openings for air of at least 5% (by-law 39(1)), unless the council accepts permanent mechanical ventilation instead (by-law 41).

So a windowless wet kitchen is not automatically wrong, but it relies on proper mechanical ventilation. If a renovation closes off the kitchen window or encloses the yard, ventilation becomes your problem.

Landed homes: when a wet kitchen needs council approval

Many older JB terraces have a wet kitchen built over the back yard. Section 70 of the Street, Drainage and Building Act 1974 bars erecting a building without the council’s prior written permission, and an alteration with new foundations, a new or bigger roof, or rebuilt outer or party walls counts as erecting (section 70(16)). A covered rear kitchen usually falls in that group.

• Usually no plans needed: painting, retiling and new kitchen cabinets are not on MBJB’s permit lists.
• Permit or plans needed: rear or side extensions, new roofs, internal walls and facade changes, through MBJB’s minor works permit or full plans.
• Getting it wrong: MBJB’s December 2022 checklist lists a penalty plan fee of 10 times the processing fee; MBIP has said late approval carries a penalty of up to 30% of the cost of the works (The Star, October 2021); section 70(13) allows fines of up to RM50,000.

See my renovation permit guide, JB’s local councils explained and, if you are buying a house with a rear kitchen, illegal extensions in subsale houses.

Condos: management approval, windows and the facade

The standard by-laws in the Third Schedule of the Strata Management (Maintenance and Management) Regulations 2015 say:

• Paragraph 27: no renovation without the management’s prior written approval (and the authority’s where needed); a deposit may be asked, and works must not weaken the structure.
• Paragraph 28: adding a platform or moving an external door or window needs both the authority and the management.
• Paragraph 29: no change to the facade without the management’s written approval.

So enclosing a yard with glass, moving the kitchen window or cutting an external wall for a hood duct all need approval first, and a structural or shear wall between kitchen and living room cannot simply be removed. A May 2026 SAYS guide put typical renovation deposits at RM2,000 to RM5,000 or more. House rules on ducts, gas and working hours differ, so ask the management office first.

Wet floors and waterproofing

Hacking wet-kitchen floor tiles to move the sink or floor trap can break the waterproofing membrane and send water into the unit below. Ask your contractor to redo and test the waterproofing before tiling; see water leaks from the unit above.

Gas, fire safety and ventilation

• Gas work needs a competent person. Installing, altering or repairing gas pipes and installations must be done or supervised by a competent person certified by the Energy Commission (Gas Supply Act 1993, section 35). Kitchen contractors should not move a piped gas point.
• Cylinders need air. LPG is heavier than air and collects at floor level, so avoid sealed cabinets and keep the hose and regulator in good condition. Check your building’s house rules on cylinders.
• Don’t leave cooking unattended. The Fire and Rescue Department’s director-general said about 60% of house fires were linked to electrical problems and named unattended cooking and gas leaks as other major causes; he advised keeping a fire extinguisher at home (Berita RTM, 3 August 2025).
• Ducted or recirculating hood. A ducted hood removes smoke and heat; a recirculating one only filters grease and smells. In condos, plan any duct opening with the management first.

Moving heavy cooking to an induction hob? Check the wiring first in older homes (see old home electrical wiring). As an illustration, a 2 kW hob used 45 minutes a day uses about 45 kWh a month, roughly RM20 at the Energy Commission’s base charges of 44.43 sen per kWh before incentives and adjustments (see my electricity bills guide). Cooking smells drifting into corridors are a common condo complaint; my guide to neighbour problems in condos covers the complaint steps.

Planning a wet and dry kitchen: a practical checklist

1. Start with how you cook and who cooks; that decides whether you need two zones.
2. Check approvals first: the approved plan for landed homes, the house rules and renovation form for condos.
3. Zone the appliances: gas hob, sink and floor trap in the wet kitchen; fridge, oven and coffee station in the dry kitchen.
4. Plan ventilation (window, yard opening or ducted hood) before closing anything off, and keep laundry away from the hob if the yard is shared.
5. Get written quotes and a contract: see hiring a designer or contractor and renovation costs.

Does a second kitchen add value? It depends on local buyers: an approved wet kitchen is often welcome in family areas, while an unapproved extension can hold up a sale (see renovations and resale value).

What I check at a viewing

• Original or added? Whether a landed wet kitchen is on the approved plan, and whether the seller has the permit.
• Leaks and damp where the extension roof joins the house (see roof leaks).
• Ventilation, gas and yard: a window or yard opening, where the hood vents, piped gas or cylinders, and whether laundry and aircon units crowd the yard.
• New launches: whether the show unit’s kitchen matches the agreement’s specifications (show unit checklist) and cabinet defects at handover (VP checklist).

Foreign buyers: Johor generally sets a RM1 million minimum price for foreigners buying residential property, with limited exceptions, so many foreign families look at larger condos and landed homes, where separate kitchens are common (New Straits Times, April 2026).

Where to buy if this matters to you

• Mount Austin: family landed homes and condos.
• Tebrau, Setia Indah and Molek: established estates where rear kitchen extensions are common; check approvals.
• Bukit Indah and Gelang Patah: newer landed townships on the west side.
• Iskandar Puteri: larger condos and landed homes near EduCity.
• Skudai, Tampoi and Kempas: older terraces and mid-range condos.

Frequently asked questions

What is the difference between a wet kitchen and a dry kitchen?

A wet kitchen is an enclosed, tiled room for heavy cooking such as frying, curries and washing raw food, usually with the gas hob, sink and floor trap. A dry kitchen is an open or semi-open area for light cooking, drinks and serving, often next to the dining area.

Do I really need both a wet and a dry kitchen?

Only if you cook with high heat, oil and strong spices most days, or have a large household. If you mainly cook light meals or eat out, one well-ventilated kitchen with a ducted hood is usually enough and saves floor space.

Do I need council approval to build a wet kitchen at the back of my terrace house?

Usually yes. A rear extension with a new roof, walls or foundations counts as erecting a building under section 70 of the Street, Drainage and Building Act 1974 and needs the council’s written permission. Retiling or new cabinets in the existing kitchen generally do not.

Can I convert an open kitchen into a closed wet kitchen in a condo?

Often yes, with the management’s prior written approval under the standard strata by-laws. Changes to external windows, doors or the facade also need approval, and structural or shear walls cannot be removed. Check your building’s house rules first.

Can I use a gas cylinder in a condo wet kitchen?

Many condo households cook with LPG cylinders, but some buildings have piped gas or house rules on where cylinders may be kept. Any work on gas pipes must be done or supervised by a competent person certified by the Energy Commission.

What is the minimum kitchen size in Malaysia?

Under by-law 42(3) of the Uniform Building By-Laws 1984, a kitchen in a residential building must be at least 4.5 square metres in area and at least 1.5 metres wide. Kitchens in homes other than shophouses must also be at least 2.25 metres high.
