Walk into any modular kitchen showroom and the built-in hob looks like the future: a sheet of black glass sitting flush in the countertop, no gaps, no legs, no grime lines. Beside it, the freestanding stainless-steel cooktop looks like the past the customer is trying to escape. That visual contrast sells a lot of hobs — and then Indian cooking moves in, with its heavy kadais, its daily thermal shocks, its masala spills, and its need for a burner to be serviced on a Sunday morning before lunch. The choice between the two is genuinely close, and it turns on four factors: cutout commitment, glass safety, serviceability, and cost.
The fundamental difference is architectural. A freestanding cooktop sits on the counter — it can be lifted, carried to the service centre, or replaced in an afternoon. A built-in hob is cut into the countertop — the stone is cut once, to that hob's dimensions, and the hob lives in that hole for the life of the kitchen unless the stone is re-cut. Everything else follows from that one fact: the hob's beauty is permanent, and so are its constraints.
This guide compares the two across the dimensions that actually decide satisfaction: the cutout and what it commits the owner to, the safety of toughened glass under Indian cooking loads, what happens when a burner fails, and what each costs over its life. The verdict is stated plainly at the end — and it will surprise buyers who assumed the showroom answer was the right one.
Cutout sizes: the commitment you cut in stone
A built-in hob needs a rectangular cutout in the countertop, and the cutout is model-specific. For a 60 cm four-burner hob, commonly cited manufacturer specs put the cutout around 560 mm wide by 480 mm deep; for 90 cm five-burner models, around 860 mm by 480 mm — but the only figure that matters is the one in the installation manual of the exact model being bought, because cutouts vary by brand and a 10 mm error means the hob either falls through or does not fit. The stone cutter needs the manual before cutting, not after. Two further commitments follow: the cabinet below the hob must be planned around it (no drawer directly under a gas hob without heat shielding — commonly cited practice keeps at least the top drawer clear or heat-protected), and replacing the hob years later means finding a model with an identical or larger cutout, since stone cannot be un-cut.
The freestanding cooktop commits to nothing. It needs a flat counter, a gas connection, and roughly its own footprint — typically 600–800 mm wide for four burners. It can be swapped for any other model in minutes, carried out for deep cleaning, and replaced without touching the stone. In rented homes, or in kitchens where the cooking setup may change, that reversibility is worth more than any aesthetic.
| Factor | Built-in hob | Freestanding cooktop |
|---|---|---|
| Installation | Cut into the countertop; cutout per the model's manual (60 cm hob ≈ 560 × 480 mm cutout, commonly cited) | Sits on the counter; no cutting, no commitment |
| Counter cleanability | Flush glass — one wipe across; no grime lines | Legs and edges trap spills; the counter under it needs periodic lifting to clean |
| Looks | Seamless, premium, showroom-finish | Utilitarian; stainless or glass-top but visibly an appliance |
| Glass safety | Toughened glass, but a dropped cooker on one point can shatter it — replacement means the whole glass top | Glass-top models share the risk; stainless models have no glass to break |
| Burner service | Technician visits home; parts are model-specific and costlier | Carry to the service centre; parts are standardised and cheap |
| Heavy Indian vessels | Check the glass load rating; sliding a full cooker across glass risks scratches and point impact | Stainless tops take abuse; pan supports are replaceable |
| Replacement in 5–8 years | Must match the existing cutout or re-cut the stone | Any model that fits the counter width |
| Indicative cost | ₹15,000–40,000+ (indicative, verify locally) | ₹8,000–15,000 for a 4-burner (indicative, verify locally) |
Glass safety, honestly
Built-in hobs use toughened (tempered) glass, typically 8 mm in commonly cited specs, which is strong against distributed loads and thermal shock within its rating. The failure mode buyers should understand is point impact: toughened glass is weakest against a hard, small-area strike — exactly what a heavy steel cooker dropped edge-first delivers. When toughened glass fails, it shatters into blunt granules (the safety feature), but the hob is unusable until the entire glass top is replaced, which is a model-specific part at a model-specific price. Stainless-steel cooktops simply do not have this failure mode. Households that regularly handle 10-litre cookers and heavy iron kadais should weigh this honestly against the look.
Serviceability: the Sunday-morning test
Apply the Sunday-morning test: a burner clogs or the ignition fails two hours before lunch guests arrive. With a freestanding cooktop, the unit is carried to the service centre or a local repair shop — most Indian towns have one — and burners, knobs and pan supports are standardised parts available off the shelf. With a built-in hob, the repair comes to the kitchen: a company technician, an appointment slot, model-specific spares that may need ordering. Neither is a deal-breaker in a metro with good service networks; outside them, the freestanding cooktop's repairability is a genuine advantage. Ask the dealer, before buying a hob, where the nearest authorised service point is and what a replacement glass top costs — the answers are more informative than the brochure.
What each costs — purchase and lifetime
The purchase gap is significant: a four-burner freestanding cooktop from a mainstream brand runs roughly ₹8,000–15,000, while a four-burner built-in hob starts around ₹15,000 and climbs past ₹40,000 for five-burner auto-ignition models with heavy pan supports — all indicative marketplace ranges to verify locally. But the lifetime math matters more. The hob adds stone-cutting labour, a model-specific replacement glass top if the glass ever fails (ask the price before buying — it is the number dealers least like to quote), and technician-visit servicing. The cooktop adds nothing beyond standardised spares. Over a decade, the hob typically costs multiples of the cooktop in total ownership — the premium buys the flush look and the wipe-clean counter, which for many buyers is genuinely worth it. It should just be bought with open eyes.
| Cost head | Built-in hob (indicative) | Freestanding cooktop (indicative) |
|---|---|---|
| Appliance, 4-burner | ₹15,000–30,000 | ₹8,000–15,000 |
| Appliance, 5-burner 90 cm | ₹30,000–45,000+ | Not applicable — cooktops top out at 4 burners typically |
| Stone cutting for cutout | ₹2,000–5,000 labour | Zero |
| Replacement glass top (if shattered) | ₹6,000–15,000, model-specific | Glass-top cooktop: ₹2,000–5,000; stainless: not applicable |
| Routine burner service | Technician visit, model spares | Carry-in service, standardised cheap spares |
| All figures | Indicative, verify locally | Indicative, verify locally |
Where it works, and where to avoid
- Built-in hob: worth it in owned homes with good service networks, where the flush look and wipe-clean counter justify the premium and the cutout commitment.
- Freestanding cooktop: the right answer for rented homes, towns with thin service networks, and households that prize repairability — plus every budget kitchen.
- Heavy-vessel households: stainless cooktops take the most abuse; if choosing a hob, verify the glass load rating and keep iron kadais off sliding drags.
- 90 cm five-burner hobs: only where the counter run and the 90 cm chimney above both exist — the hob, the cutout and the chimney are one system.
- Avoid: buying a hob without reading the cutout manual before the stone is cut; placing any hob without 150 mm wall clearance and 300 mm sink separation; choosing on looks alone without asking the replacement-glass price.
