Commercial Tandoor Oven Buying Guide 2026: Gas vs Charcoal, Drum Sizes, BTU & FOB Prices
A commercial tandoor is the centrepiece of any Indian, Pakistani, Afghan, Persian or modern fusion kitchen — and increasingly a profit driver for hotels, banqueting operations and cloud kitchens across the Middle East, Africa and South Asia. If you are specifying a tandoor for a new restaurant, a hotel production kitchen or a central kitchen, this 2026 buying guide walks through the fuel options, drum sizes, key specifications, realistic FOB China price ranges and the installation details that decide whether a tandoor performs for a decade or cracks within a year.
What is a commercial tandoor and how does it work?
A tandoor is a cylindrical clay oven that cooks by a combination of intense radiant heat from the pot walls, convective heat rising through the mouth, and direct heat from the fuel bed below. A natural-clay or fireclay pot sits inside an insulated stainless-steel shell; a layer of ceramic fibre or rockwool between the two keeps the outer body cool and holds heat in. Skewers of marinated meat hang vertically from the rim, while breads such as naan and roti are slapped onto the near-vertical inner wall, where they bake in about 60–90 seconds.
Because the pot stores so much energy, a tandoor recovers temperature quickly between batches — the reason a single unit can keep pace with a busy grill line. The trade-off is weight and thermal mass: a commercial tandoor is heavy, slow to pre-heat from cold, and best left running through service.
Gas vs charcoal vs electric tandoor: which should you choose?
Charcoal or wood-fired tandoors give the authentic, smoky char that defines traditional tandoori cooking. They are prized by specialist restaurants but demand more from the kitchen: heavier extraction, make-up air, a spark arrestor and more labour to light, tend and clean. Gas tandoors — running on LPG or natural gas — light instantly, hold a steady temperature and are far easier to operate at volume, which is why most hotels and high-throughput kitchens specify them. Many operators choose a dual gas-and-charcoal design: gas for fast, reliable heat, with a charcoal tray for finishing flavour. Electric tandoors exist for indoor or ventilation-limited sites, but their lower output and slower recovery suit cafes and small menus rather than banquet volumes.
Commercial tandoor sizes and capacity
Tandoors are sized by the internal clay-pot diameter and mouth opening. As a planning guide:
| Class | Pot diameter | Approx. skewers / naan per batch | Typical gas input | Approx. weight |
|---|---|---|---|---|
| Small (cafe / cloud kitchen) | 500–560 mm | 8–12 | 15,000–25,000 BTU/hr | 80–120 kg |
| Medium (standard restaurant) | 650–750 mm | 14–18 | 25,000–35,000 BTU/hr | 120–180 kg |
| Large (hotel / banquet) | 900 mm and up | 20–28 | 35,000–50,000 BTU/hr | 180–250 kg |
Square-bodied hotel tandoors offer more working room around the mouth and a flat base that suits fixed installations, while round drum models are lighter and cheaper to ship. Match the class to your peak covers rather than your average — a tandoor that is undersized for Friday-night or Iftar volume becomes the bottleneck for the whole hot line.
Key specifications to check before you buy
Body material: a 304 stainless outer shell resists corrosion and cleans easily; premium hotel lines use copper cladding for appearance and durability. Clay pot: the quality and thickness of the natural-clay or fireclay pot largely determines cooking performance and lifespan; a well-cured, evenly thick pot resists cracking. Insulation: ceramic fibre or high-density rockwool between pot and shell keeps the outside safe to touch and cuts fuel use. Burner and controls (gas models): look for a robust cast-iron or stainless burner, a thermocouple and a flame-failure (gas safety) valve as standard. Grates, skewer sets and warming ledges round out a professional package.
These are exactly the areas where a made-to-order unit pays off. Because the shell is welded and the pot is fitted in-house, a capable factory can build the drum diameter, round or square body, LPG or natural-gas manifold, copper cladding and banquet-style front doors to your drawing — typically on a 25–45 day production lead time rather than the 60–90 days common for bespoke equipment. Ask for a spare thermocouple, burner and a replacement clay pot in the first order so a hairline crack never takes the station out of service.
How much does a commercial tandoor cost?
Prices vary with size, body material and fuel system. As a 2026 reference, typical FOB China ranges are:
| Model type | Typical FOB China price |
|---|---|
| Small single-drum, stainless, gas or charcoal | US$550–1,000 |
| Medium restaurant drum, stainless | US$1,000–1,800 |
| Large / square hotel-line / copper-clad | US$1,800–3,500+ |
Add ocean freight, duties and any local certification for your market. For a hotel banqueting kitchen in Qatar or a high-volume grill house in the UK, the large square gas model is usually the right call; a delivery-only cloud kitchen in Nairobi or Riyadh is often better served by a compact single drum that fits a tight footprint and a modest LPG supply.
Installation, ventilation and safety
Tandoors are heavy and run hot, so plan the site early. Confirm the floor can carry the loaded weight, and leave the clearances to combustible surfaces specified by the manufacturer. Ventilation is non-negotiable: a Type I grease canopy with adequate exhaust volume, dedicated make-up air, and — for charcoal — a spark arrestor. Gas models need a regulator correctly sized for LPG or natural gas and a certified connection. Season a new clay pot slowly over several low-heat cycles before first service to prevent thermal shock.
How to source a commercial tandoor from China
China remains the most competitive origin for commercial tandoors, but quality varies widely between workshops, so the factory you choose matters more than the headline price. Look for a supplier that welds its own stainless shells, cures its clay pots properly, fits recognised gas-safety components and can provide the certification and documentation your customs authority requires. For a vetted starting point, see our guide to the top commercial kitchen equipment manufacturers in China, then ask each candidate for reference photos of installed tandoors and a sample of their gas-safety and insulation build.

Running costs and daily operation
Fuel is the biggest running cost, and it favours planning. A gas tandoor on LPG is cheap to idle and quick to bring back to temperature, so many kitchens light it at prep and hold it through service rather than cycling it. Charcoal costs more per hour and needs a member of staff to manage the bed, but for a specialist restaurant that smoky signature is the product. Whichever fuel you choose, budget for consumables and wear parts: skewers, the charcoal grate, burner jets and the thermocouple on gas units all get hard use. Daily cleaning is simple but essential — ash removal for solid fuel, and a wipe-down of the stainless shell — while the clay pot should be brushed, never doused with cold water when hot. Treated well, a good clay pot lasts years; shocked with water or run empty at full heat, it can crack in weeks.
Common mistakes to avoid when buying a tandoor
Three errors show up again and again. The first is undersizing: buyers spec for average covers and then choke on peak nights, so size for your busiest service. The second is ignoring ventilation: a tandoor without proper extraction and make-up air will fail inspection and make the kitchen unbearable, and charcoal without a spark arrestor is a fire risk. The third is buying on price alone: a thin, poorly cured clay pot or an unbranded gas valve is a false economy that costs far more in downtime than it saved at purchase. Confirm the fuel type against your actual gas supply, insist on a gas-safety valve, and order spare parts with the unit so a small failure never closes the station.
Frequently asked questions
How hot does a commercial tandoor get?
A working commercial tandoor typically runs between 350°C and 450°C (660–840°F), with the hottest zone near the top of the clay pot. That intense radiant and convective heat is what cooks a naan in 60–90 seconds and seals tandoori meats quickly while keeping them moist.
Gas or charcoal tandoor — which is better for a restaurant?
Charcoal delivers the smoky, traditional flavour many chefs want, but needs strong extraction, make-up air and more labour. Gas tandoors light instantly, hold temperature consistently and are easier to run at volume, which is why most hotels and high-throughput kitchens choose gas or a dual gas-plus-charcoal design. Electric models suit lower-output or indoor sites with limited ventilation.
How much does a commercial tandoor cost?
As a 2026 guide, typical FOB China prices run about US$550–1,000 for a small single-drum stainless model, US$1,000–1,800 for a medium unit, and US$1,800–3,500+ for large, square hotel-line or copper-clad tandoors. Fuel system, body material and drum size drive the difference.
What ventilation does a tandoor need?
A tandoor produces high heat and, with charcoal, smoke and sparks. Plan for a Type I grease canopy with adequate exhaust volume, dedicated make-up air, and a spark arrestor for solid-fuel models. Gas units need a correctly sized LPG or natural-gas regulator and clearance to combustibles.
Can I get a tandoor customised for my kitchen?
Yes. Because a tandoor is essentially a clay pot inside a welded stainless shell, drum diameter, round-versus-square hotel bodies, LPG or natural-gas manifolds, copper cladding and front-loading banquet doors can all be built to your drawing, usually on a 25–45 day production lead time.
