About this calculator
The Island Kitchen Cost Calculator estimates the cost of a modular kitchen with a central island — the aspirational layout for premium 3+ BHK and villa kitchens. The2026 India range for an L + island or U + island setup is ₹4.5–12 lakhdepending on island size, material and appliance integration.
Islands need at least 120 sqft of kitchen floor area with 36–42 inches of clearance on all sides. The island itself adds 6–10 Rft of cabinetry and is often where the hob or sink moves — pushing plumbing and electrical work up by 25–40% over a standard L-shape.

How the calculation works
Base L of 11 Rft at ₹3,500/Rft laminate = ₹38k + 6 ft island at ₹4,500/Rft (counter both sides) = ₹27k cabinetry. Add counter (quartz preferred at ₹600/sqft × 22 sqft = ₹13k), accessories ₹40k, chimney + hob ₹45k, appliance integration ₹60k. Realistic turnkey: ₹4.5–8 lakh in laminate; ₹8–12 lakh in PU.
Why this estimate is more accurate
Islands look simple but the plumbing and electrical for hob-or-sink-on-island can blow up the budget by ₹1–2 lakh on its own. Knowing the realistic cost of each island function helps you decide whether to keep it as decorative storage or commit to full appliance integration.
Material comparison
| Island function | Added cost | Floor area need | Best for |
|---|---|---|---|
| Decorative + storage only | ₹85k–2.5 lakh | 110+ sqft | Most homes |
| + breakfast seating | ₹1.1–3 lakh | 130+ sqft | Open-plan kitchens |
| + hob with downdraft | ₹1.8–4 lakh | 150+ sqft | Villa kitchens |
| + sink + dishwasher | ₹1.5–3.5 lakh | 140+ sqft | Family kitchens |
| Full prep + cooking island | ₹2.5–5 lakh | 180+ sqft | Luxury villas |
What affects the final cost
- Island size — 4 ft minimum (decorative), 6 ft sweet spot, 8 ft+ needs villa-scale kitchen.
- Clearance — 36-inch minimum on all sides; 42 inches if you have a sit-down breakfast counter.
- Plumbing extension — sink-on-island needs new drain + supply line; ₹35–80k.
- Electrical — hob + downdraft on island ₹40–90k for circuit + exhaust.
- Counter overhang — for seating, 12-inch overhang requires steel support; ₹15–30k.
- Storage on both sides — doubles cabinetry quantity vs wall-side only.
