Introduction: Why Your Renovation Budget Keeps Growing
You’ve seen the Instagram transformations. The jaw-dropping kitchen islands, the spa-like bathrooms, the basement that looks like a boutique hotel lounge. What you don’t see is the invoice.
Here’s the reality: a renovation quote prices the work a contractor will do—it does not price the consequences of disturbing a home that is already standing. Demolition, discovery, disruption, and delay routinely add 30% to 50% on top of the quote. That’s why renovation needs a 15–20% contingency where a new build needs only 10%.
This guide by Vaastvik Design Group breaks down the real cost of a renovation in Noida, Greater Noida, Ghaziabad, and across Delhi NCR room by room, so you can budget like a professional—not like someone hoping for the best.
How Much Does a Home Renovation Cost? The Big Picture
Before diving into individual rooms, understand the overall cost of a renovation and the two lenses that answer two different questions:
Per-square-foot (₹/sqft): Answers “How big is my total budget?” A blended rate of ₹1,800/sqft on a 1,050 sqft flat gives roughly ₹19 lakh—but that average hides a ₹4,500/sqft kitchen and a ₹300/sqft balcony.
Per-room (₹/room): Answers “Where should that budget go, and what do I cut first?” The kitchen, master bedroom, living room, and second bedroom typically absorb around 70% of a fit-out budget.
General Cost Tiers (2026)
| Tier | Scope | Cost Per Sq Ft (India) |
| Refresh | Cosmetic updates, paint, minor repairs | ₹150–₹350 |
| Partial Interior | Select rooms, modular work | ₹800–₹1,200 |
| Full Interior | Complete home fit-out | ₹1,500–₹2,500 |
| Gut + Rebuild | Structural changes, full overhaul | ₹3,500–₹5,500+ |

Room-by-Room Renovation Cost Breakdown
1. Kitchen Renovation Cost: The Single Most Expensive Room
The kitchen is where the most money per square foot goes because it stacks four costly systems into one small space: cabinetry, countertop, appliances, and services (plumbing, electrical, exhaust).
2026 Kitchen Remodel Costs:
- Minor/Refresh: ₹21.25 lakh
- Mid-Range: ₹51 lakh
- Major/Upscale: ₹1.27 crore+
Where Your Kitchen Budget Goes (for a ₹42.5 lakh project):
| Category | % of Budget | Cost |
| Cabinets & Hardware | 29% | ₹12,32,500 |
| Labor & Installation | 25% | ₹10,62,500 |
| Appliances | 14% | ₹5,95,000 |
| Countertops | 10% | ₹4,25,000 |
| Flooring | 7% | ₹2,97,500 |
| Lighting & Fixtures | 5% | ₹2,12,500 |
| Plumbing & Fixtures | 4% | ₹1,70,000 |

Pro Tip: Moving walls or plumbing doubles costs. Keep the layout if possible—this is the single biggest saving in any modular kitchen setup or kitchen remodel.
2. Bathroom Renovation Cost: Small Room, Big Numbers
The average bathroom remodel in 2026 costs around ₹8.5 lakh to ₹25.5 lakh.
Bathroom Cost by Size:
| Bathroom Type | Cost Range |
| Small/Powder Room (under 50 sq ft) | ₹4,25,000–₹12,75,000 |
| Standard Full Bathroom | ₹12,75,000–₹34,00,000 |
| Master Bathroom | ₹21,25,000–₹29,75,000 |
| Luxury Primary Suite | ₹68,00,000+ |
Source: Vaastvik Design Group Hidden Costs Guide 2026
The Fixture Relocation Trap: Moving a toilet or shower means opening walls and floors, running new drain and supply lines, often cutting joists, and pulling additional permits. This cascade adds ₹85,000 to ₹4,25,000 per fixture moved.
ROI Reality: A mid-range bathroom remodel recoups about 74% of its cost at resale. An upscale remodel recoups about 45%. The non-financial return—daily comfort, accessibility—usually tips the decision.
3. Basement Finishing Cost: The Best Value Per Square Foot
A finished basement adds 500–1,200 square feet of living space for less per square foot than adding an addition. Most homeowners spend around ₹27.2 lakh.
Basement Finish Levels:
| Finish Level | Total Cost | Per Sq Ft |
| Basic (drywall, paint, flooring) | ₹8,50,000–₹25,50,000 | ₹1,275–₹2,550 |
| Mid-Range (bathroom, wet bar) | ₹25,50,000–₹42,50,000 | ₹2,125–₹4,250 |
| High-End (full suite, custom) | ₹63,75,000+ | ₹4,250+ |
The Moisture Warning: Waterproofing must come FIRST. Finishing a wet basement is throwing money away. Typical waterproofing costs ₹1,27,500 to ₹12,75,000 depending on severity. Spending ₹6,80,000 on waterproofing now beats spending ₹34,00,000 on a redo later.
4. Bedroom Renovation & Addition Costs
A standard bedroom renovation (cosmetic updates, floorhttps://www.forbes.com/home-improvement/ing, paint, lighting) typically runs ₹1.2–₹1.8 lakh, making it an essential component when evaluating the overall cost of a renovation.
Adding a New Bedroom:
| Room Type | Cost Per Sq Ft | Typical Total |
| Basic Bedroom (12×14) | ₹12,750–₹21,250 | ₹17,00,000–₹51,00,000 |
| Bedroom + Bathroom | ₹21,250–₹29,750 | ₹85,00,000+ |
| Second Story Addition | ₹34,000+ | ₹63,75,000+ |
Source: Vaastvik Design Group Hidden Costs Guide 2026
Key Insight: Finishing a basement or attic costs 40–60% less than building an addition because the shell already exists.
5. Living Room Renovation Cost
The living room is the “impression room”—where guests form their first opinion. When evaluating the total cost of a renovation, a typical living room renovation in India runs ₹1.5 to ₹5 lakhs depending on scope.
- Essential: ₹75,000–₹1.5 lakh
- Comfort: ₹1.5–₹3 lakh
- Premium: ₹3–₹5 lakh+
The Hidden Costs That Blow Your Renovation Budget
A renovation quote does not include the costs that exist only because the home already exists and is occupied. Here’s what actually shows up:
| Hidden Cost | Typical Range | When It Hits |
| Demolition + Dismantling | ₹25,000–₹90,000 | Day one |
| Debris/Malba Removal | ₹15,000–₹50,000 | Throughout |
| Hidden Damage Repair | ₹50,000–₹2,00,000+ | When walls open |
| Society Fees + NOC + Deposit | ₹25,000–₹1,50,000 | Before work starts |
| Temporary Accommodation | ₹30,000–₹1,50,000 | If you move out |
| Design Changes Mid-Execution | 2–3× original cost | Worst possible time |
| Electrical Rewiring | ₹40,000–₹1,50,000 | When old wiring fails |

The Golden Rule: Keep 10–15% contingency for a new fit-out. Keep 15–20% for a renovation. The older the building, the higher the contingency.
Frequently Asked Questions
How much does a full home renovation cost in 2026?
Full home renovation in India typically runs ₹1,500 to ₹4,000 per sq ft, so a 1,000 sq ft home usually costs ₹15 lakh to ₹40 lakh depending on scope and finish level.
Which room is the most expensive to renovate?
The kitchen is the single most expensive room per square foot, followed by bathrooms and master bedrooms. These three rooms typically absorb 50–60% of a total renovation budget.
How much should I budget for unexpected renovation costs?

Renovating is generally 40–60% cheaper than building an addition or new construction, especially if you’re finishing existing space like a basement or attic rather than adding square footage.
What is the best ROI renovation?
Kitchen and bathroom remodels typically offer the best return, with mid-range bathroom remodels recouping around 74% of costs at resale. Basement finishing also delivers strong value per square foot.
How long does a renovation take?

Final Word: Budget Like You Mean It
The true cost of a renovation isn’t just the quote. It’s the initial quote plus the hidden cost of a renovation associated with undoing decisions made by previous builders and owners you never met.
Your action plan:
- Size the envelope first using per-square-foot rates for your city and scope.
- Allocate per room—spend premium in the kitchen and master bath, stay lean in the foyer and balcony.
- Add 15–20% contingency and treat it as sacred. You will need it.
- Price the hidden costs—demolition, debris removal, society deposits, and temporary accommodation—before you sign anything.
- Get detailed itemised quotes from reputable local firms like Vaastvik Design Group and ask what they exclude. The answer is where your budget will actually go.
Renovation is half construction, half discovery. Budget for both.
