Office pantry fit-out in Dubai: water, waste and what it costs

Where water and waste actually exist in a tower

In a Dubai office tower the wet services live in the core. Cold water comes off a riser with a meter or sub-meter, and soil and waste stacks sit behind the toilet blocks on the same vertical line, floor after floor. That geometry, not the floor plate, sets the realistic pantry zone.

Water is the easy half. Pipe runs almost anywhere in the ceiling void with enough length, isolation valves and insulation. Waste is the half that says no, because it needs continuous fall. A single bowl sink wants a 40 mm waste; add a dishwasher and a second bowl to the same branch and it becomes 50 mm. A fall in the region of 1 in 40 to 1 in 80 has to be held all the way to the stack, and every bend and level change eats the headroom you have above the ceiling. Branch length is limited before the run needs venting or an air admittance valve, and the 75 mm trap seal that keeps drain odour out of the office is exactly what a badly vented branch empties over a long weekend.

So the useful question at lease stage is how much fall you have between the underside of the slab and the top of the ceiling across that distance, not how far the pantry sits from the core on a plan. Ask for the landlord's drainage drawing, then open the ceiling in two or three positions and look, because in a fifteen-year-old tower an as-built is a hypothesis. Who owns the tie-in to the stack is part of what belongs in an MEP package.

When the drain is nowhere near where you want the pantry

Raising the floor locally is the cleanest answer. A plinth or a step buys the fall, and an office with a raised access floor may already have the void. It costs floor area and a threshold detail, and it has to be drawn before the finishes schedule rather than after.

Coring the slab to drop into the floor below is what tenants ask for and rarely get. A post-tensioned slab gets scanned with ground penetrating radar before anyone drills, the structural engineer signs the position, and plenty of fit-out manuals forbid new penetrations outright. Where it is allowed, your pipe then lives in the ceiling void of the tenant underneath, which needs their access, the landlord's written consent and a maintenance route for the rest of the lease.

A macerator removes the gravity problem and brings its own. Pumped waste discharges through small bore pipe that can rise, so the pantry goes where you want it. In exchange you own a pump with a power circuit, a noise level the boardroom next door will hear, a service panel that has to stay reachable, and a failure mode that is wet. We specify them when the alternative is putting the pantry in the wrong part of the floor, and we say plainly what the client is signing up for.

The tenant below you decides your waterproofing

A pantry is a wet area, and treating it as a dry room with a sink in it sends the bill to somebody else's ceiling.

Waterproofing goes under the whole pantry floor rather than in a patch at the sink, turned up the walls behind the units and dressed into the threshold. Liquid-applied membrane is the usual choice on a fit-out because it follows the detail. The part that gets skipped is the proof: a flood test held for 24 to 48 hours, witnessed, photographed and filed before screed and tiles cover it. That is trade practice rather than a code line, and it is the only evidence you will hold when the tenant below reports a stain.

Fit-out manuals add conditions that are not negotiable. Wet areas are commonly banned above electrical rooms, server rooms and landlord plant, and sometimes above another tenant's demise entirely. An upstand at the threshold appears in many manuals, a drip tray under the dishwasher in most, and newer towers increasingly ask for leak detection wired to a solenoid valve that shuts the supply off by itself. Read those clauses before a designer draws, with the same seriousness they get on genuinely wet commercial work such as salon and spa plumbing.

Extract, and the line you cannot cross

A pantry needs mechanical extract. Odour, steam off a boiling tap, heat from a fridge compressor and a dishwasher in an enclosed room do not clear on their own. The duct usually goes into the landlord's toilet and pantry extract riser, which is where it gets interesting, because that riser was sized years ago for the toilets and often has nothing spare. Measure the available capacity before anyone promises the client an enclosed pantry. A tea point is designed on air changes, around ten per hour depending on volume and designer, not on the canopy volumes a kitchen needs. A recirculating filter hood is not extract and will not satisfy anyone reading the drawing.

Then the line. No cooking means no grease, and no grease means ordinary galvanised ductwork, ordinary fire dampers, no kitchen approval set. The moment the equipment schedule carries a hob, a grill or anything throwing grease-laden vapour, the job becomes a commercial kitchen: welded liquid-tight grease duct, access panels along the run, a discharge point the building will argue about, and a different approvals queue. A microwave and a toaster sit on the safe side. An induction hob is a conversation with the landlord. Open flame in a leased office tower is a refusal.

A pantry is the densest electrical point on the floor

Nothing else on an office floor draws like a pantry per square metre. Realistic connected loads: bean-to-cup coffee machine 2 to 3 kW, under-counter boiler or boiling tap 1.5 to 3 kW, dishwasher 2 to 3 kW while the element heats, microwave around 1.2 to 1.5 kW drawn, undercounter fridge a couple of hundred watts, ice maker a few hundred more. A modest pantry is 8 to 12 kW connected inside four square metres.

Diversity means you rarely draw all of it at once, but the circuits have to be there. Dishwasher and boiler each want a dedicated radial circuit and a local isolator above the worktop where a hand can reach it, not behind the appliance. Socket positions follow the appliance schedule, so the appliance schedule has to arrive before the distribution board is ordered, which on a fast programme it often does not. Spare ways in the board are cheap now and expensive in year three.

Where the pantry tips a floor past its agreed capacity you are in another queue entirely. A load increase goes to DEWA through an enrolled consultant and contractor and is counted in weeks from the date a correct pack was lodged. Few office pantries approach the 400 kW threshold that forces a substation discussion, but a tenant stacking a pantry, a server room and a boardroom AV wall onto a floor already at its ceiling can find it.

Do you need DM and Food Control if nobody cooks

The pantry gets no permit of its own. It is drawn into the fit-out submission, with water, waste, extract and power on the MEP set, and approved with everything else. On mainland Dubai that means the Dubai Municipality fit-out permit through the Building Permit System, where a complete and compliant file usually comes back in ten to twelve working days, with a Civil Defence NOC of one to three weeks running alongside and four to eight weeks the honest number from lease signature. Off mainland, the desk changes: our JLT offices went through a DDA fit-out permit, and d3, Trakhees jurisdictions and the free zone districts each have their own route.

Food Control is the question tenants ask most and read least correctly. A food permit follows the trade licence activities, not the presence of a sink. A company licensed for consultancy, trading or technology, running a tea point for staff and visitors, is not a food establishment, so no food licence and no Food Control inspection of the pantry. Change any part of that and the answer changes with it. A staff canteen where meals are prepared, a pantry inside a unit whose licence carries food activities, or anything served to the public puts you under food establishment rules, with their own layout, sink and finish requirements. Confirm the activity list with your licensing consultant before a designer draws, and verify the current Dubai Municipality requirements directly with the authority rather than relying on a summary.

Civil Defence reads the pantry as partitions and detection. A new enclosed room needs its own smoke detection, sprinkler coverage and emergency lighting, the same as a meeting room does.

Cat A, Cat B and whose pantry it is

A pantry is almost always Category B, which means yours. Category A is the landlord's lettable office: ceiling, lighting, primary air conditioning, sprinklers, floor finish. Some towers hand over a Cat A tea point, and more of them leave a capped water and waste point near the core without mentioning it in the brochure. Get the unit's state in writing before signature, because "fitted" in a listing means whatever the last tenant left behind. What each starting line leaves you to build is set out in our note on shell and core, Cat A and Cat B.

The lease that lets you build the pantry will usually make you remove it. Reinstatement means stripping the joinery and services and capping the drainage properly rather than plugging it, funded by you at the end of a term when nobody has budgeted for it. Price it at the start.

What it costs and how long it takes

We do not publish a pantry rate, for the same reason we publish no office rate: the number is an output of a scope. For orientation, market bands published by Dubai joinery and fit-out suppliers put pantry casework broadly between AED 1,800 and 3,200 per linear metre. That is a reported market band rather than a rate card and not ours, it assumes a given spec of carcass, doors and worktop, and it says nothing about the services that decide whether the pantry works.

Joinery moves with worktop material, carcass and edging, integrated appliances, bespoke against modular, and whether a factory can build the drawing as drawn. Services move with distance to the stack, whether a macerator is needed, available extract capacity, and spare ways in the board. On programme a pantry rarely owns the critical path by itself, but its first fix and second fix take roughly two to three weeks of site time inside the same window as every other service in the ceiling, and the long lead item is the joinery, not the pipework. The expensive version of a pantry is always the one that changes position after coordination. How we sequence a tenant job around that sits in our process, and the wider package in office fit-out.

Where tenants lose the money

The position gets chosen off a mood board instead of a drainage drawing. The dishwasher appears on the appliance list after the waste branch is sized. Nobody asks for a local isolation valve, so one dripping tap shuts off water to the floor. The macerator or the trap ends up behind fixed joinery with no access panel. Waterproofing gets value engineered out because it is only a sink. Reinstatement never reaches the budget at all.
