Renovation Costs Per Square Foot in India
When planning an apartment or flat renovation, estimating by renovation costs per square foot is the standard rule of thumb used by civil contractors, interior designers, and architects across Indian metros (Mumbai, Delhi NCR, Bengaluru, Hyderabad, Chennai, and Pune).
Depending on whether you choose standard modular factory fittings or premium custom veneer woodwork and Italian marble, renovation costs fall into three clear quality tiers:
₹700 – ₹1,100 / sq ft
Pre-laminated particle board, surface repainting with tractor emulsion, basic vitrified 2×2 floor overlay, existing sanitaryware retention.
₹1,200 – ₹2,000 / sq ft
BWR marine ply with 1mm laminate, Gypsum false ceiling with cove LED, new vitrified tiles (4×2 ft), Jaquar fittings, Asian Paints Royale.
₹2,200 – ₹3,500+ / sq ft
Acrylic/PU kitchen, Italian composite marble or wooden flooring, concealed Kohler/Grohe diverters, multi-zone smart automation, veneer panelling.
| Apartment Type | Carpet Area | Economy (₹700–₹1.1K) | Standard (₹1.2K–₹2K) | Premium (₹2.2K–₹3.5K) |
|---|---|---|---|---|
| 1 BHK Flat | 400 – 550 sq ft | ₹2.8 – ₹4.8 Lakh | ₹5.0 – ₹8.5 Lakh | ₹9.0 – ₹15.0 Lakh |
| 2 BHK Flat | 800 – 1,050 sq ft | ₹5.6 – ₹9.0 Lakh | ₹10.0 – ₹16.5 Lakh | ₹18.0 – ₹28.0 Lakh |
| 3 BHK Flat | 1,200 – 1,600 sq ft | ₹8.5 – ₹14.5 Lakh | ₹15.0 – ₹25.0 Lakh | ₹28.0 – ₹45.0 Lakh |
2BHK Renovation Cost Breakdown (800–1,000 Sq Ft)
A 2BHK flat is the most common apartment format in urban India. When undertaking a comprehensive remodel, homeowners often wonder how their budget divides across civil work, carpentry, plumbing, and electricals.
Here is a trade-by-trade breakdown for an 850 sq ft 2BHK flat renovated to standard-plus specifications:
L-shaped or parallel layout (approx 65 sq ft counter length). Includes boiling water resistant (BWR IS:303) marine ply carcass, 1mm high-gloss anti-scratch laminate shutters, soft-close Blum/Hettich drawer channels, granite or quartz countertop, and stainless steel sink.
Includes complete floor and wall hacking, Dr. Fixit polymer membrane waterproofing (crucial for preventing slab leaks to downstairs flats), vitrified anti-skid floor and glazed wall tiles up to 7 ft lintel, CPVC internal plumbing, Jaquar diverters, and wall-hung commodes with concealed cisterns.
Gypsum board false ceiling (Saint-Gobain Gyproc 12.5mm) across living room, dining, and 2 bedrooms (approx 600 sq ft covered area). Includes GI channel framework, LED cove profile lighting, and recessed COB spotlights.
Laying 4×2 ft or 2×2 ft glazed vitrified tiles (Kajaria, Somany, Nitco) over existing floor using cement mortar bedding or polymer thinset adhesive. Includes skirting and epoxy grout in wet transitions.
Thorough scraping of old paint, 2 coats of Birla White / Asian Paints TruCare wall putty, 1 coat primer, and 2 coats of washable interior acrylic emulsion (Asian Paints Royale or Apcolite).
Two floor-to-ceiling 3-door wardrobes with lofts (commercial MR ply with laminate), TV unit with back-paneling, and an entryway shoe cabinet.
Hacking existing tiles, clearing debris per society guidelines, chased wall conduits for AC power points, modular switches (Legrand/Schneider), and post-construction chemical deep cleaning.
Total Standard 2BHK Investment
₹6.3 Lakh – ₹11.7 Lakh
Average turnkey cost: ~₹8.5 Lakh for full 850 sq ft flat
Kitchen Renovation Cost in India (Modular Kitchen Deep Dive)
Kitchens account for nearly 25% to 30% of an apartment remodel. In Indian cooking, heavy spices, oil vapor, and rigorous daily washing demand moisture-resistant and heat-tolerant construction:
Carcass & Cabinet Base
BWR / BWP Marine Plywood (IS:710): The gold standard for Indian kitchens. Resists boiling water, steam, and pests. Avoid particle board or standard MDF under the sink where plumbing leaks occur.
Cost: ₹1,100 – ₹1,800 / sq ft of cabinet surface
Shutter Finish
Acrylic vs 1mm High-Pressure Laminate: Laminate is budget-friendly, scratch-resistant, and durable. Acrylic provides a glass-like ultra-gloss modern finish but is vulnerable to scratches.
Laminate: ₹180 – ₹350 / sq ft | Acrylic: ₹450 – ₹850 / sq ft
Countertop Selection
Jet Black Granite vs Engineered Quartz: Jet black granite remains virtually indestructible against turmeric (haldi) and lemon juice stains. Quartz looks sleek and non-porous but requires heat trivets.
Granite: ₹140 – ₹320 / sq ft | Quartz: ₹300 – ₹800 / sq ft
Hardware & Pullouts
Soft-Close Tandem Boxes (Hettich / Hafele): SS wire baskets cost less upfront but rust over 5 years. Tandem boxes carry 30–50kg pots with smooth silent glides.
₹3,500 – ₹6,500 per drawer set
Bathroom Renovation Cost in India (Waterproofing & Fittings)
Bathroom leaks are the number one cause of conflict between apartment neighbors in Indian housing societies. Cutting corners on bathroom waterproofing leads to costly ceiling seepage lawsuits.
- Waterproofing Membrane (₹30 – ₹55 / sq ft): Apply 2 coats of polymer-modified cementitious slurry (such as Dr. Fixit Fastflex or Fosroc Brushbond) over the sunken slab, turning at least 1 foot up the brick wall. Always conduct a 48-hour water ponding test before laying tile bedding.
- CPVC Concealed Piping (₹12,000 – ₹25,000 / bath): Replace old galvanized iron (GI) pipes with SDR-11 CPVC pipes (Astral, Ashirvad) with brass transition fittings.
- Tiling & Grouting (₹40 – ₹90 / sq ft tile + ₹30 labor): Vitrified tiles on walls up to door height; matte anti-skid vitrified tiles for flooring. Use epoxy grout on the floor to prevent water permeation through grout lines.
- Sanitaryware & Brassware (₹25,000 – ₹70,000 / bath): Wall-mounted WC with concealed pneumatic flush tank (Geberit / Jaquar) makes cleaning effortless. Diverters and overhead rain showers add modern elegance.
Financing Your Renovation: Personal Loan vs Home Improvement Loan
If you lack ready cash for a ₹6 to ₹12 Lakh apartment renovation, Indian banks offer two primary financing vehicles:
Secured against your existing property or home loan. Interest rates range between 8.75% and 9.75% with repayment tenures up to 15 years. Lower EMI burden, and interest qualifies for tax deduction under Section 24(b) up to ₹30,000/year.
Unsecured financing disbursed in 24–48 hours with minimal paperwork. Interest rates are significantly higher at 10.5% to 15.0% with short 3-to-5-year tenures, leading to substantially higher monthly EMIs.
