Home Renovation Cost in Bangalore (2026): Room-by-Room Rates

Ask five contractors for a renovation quote and you'll get five numbers that differ by lakhs — for the same flat. That's not (always) dishonesty. It's because "renovation" can mean anything from a paint refresh to gutting the home down to brick. Until the scope is pinned down, the price can't be.

This guide pins it down. We'll separate renovation into three clear scopes with per-sq-ft rates, give you room-by-room budgets for the two most expensive rooms in any renovation (kitchen and bathroom), expose the hidden costs that surface only after demolition, and end with a practical framework — including the contingency percentage we insist on for every project.

The Quick Answer

Cosmetic Refresh

₹150–400 / sq ft

Painting, minor repairs, lighting swaps, soft furnishings. No civil work. A 1,000 sq ft 2BHK: ₹1.5–4 L.

Standard Renovation

₹800–1,500 / sq ft

New modular kitchen & wardrobes, false ceiling, some flooring, electrical updates. A 2BHK: ₹8–16 L.

Full Gut Renovation

₹1,800–3,500+ / sq ft

Demolition, civil changes, full plumbing/electrical rework, all-new interiors. A 2BHK: ₹18–35 L+.

Why Renovation Costs Differently Than New Interiors

If you've priced interiors for a new flat, recalibrate — renovation carries four cost layers a new home never sees:

• Demolition & debris removal (₹15–40/sq ft). Old cabinetry, tiles, and false ceilings must be broken, bagged, carried down, and legally disposed of. In high-rises, debris lift charges and society rules add more.
• Undoing before doing. Every surface must be prepared: old adhesive ground off, walls re-plastered, waterproofing redone. New-build work starts at zero; renovation starts at minus one.
• Hidden damage. The moment tiles come off, you meet the house's history — seepage, termite trails, hollow plaster, undersized wiring. Some of it must be fixed before anything new goes in.
• Working occupied. If you're living in the home during work, phasing, dust protection, and daily cleanup slow the project and add labour cost. Moving out for 6–8 weeks is often cheaper overall.

What quotes can't see: the state of walls and pipes behind old tiles is unknown until demolition day — which is why contingency isn't optional.

Renovation Cost Per Sq Ft, by Scope (Bangalore 2026)

Rates assume standard-grade materials. Premium finishes (veneer, acrylic, imported hardware, natural stone) push each band up 30–60% — for exactly what changes between grades, see our essential vs luxury interiors comparison.

Full-Home Renovation Budgets by Flat Size

Where a standard 2BHK renovation budget actually goes

Here's a typical split of a ₹12 lakh standard renovation, so you can see which line items dominate:

Modular kitchen~₹3.4 L

Wardrobes & storage~₹2.6 L

False ceiling & lighting~₹1.4 L

Painting & wall prep~₹1.2 L

Electrical rework~₹1.0 L

Demolition & disposal~₹0.7 L

Flooring (partial)~₹1.0 L

Contingency (~10%)~₹0.7 L

Notice the kitchen and wardrobes alone consume half the budget — which is why the next two sections go deep on the rooms that decide your total.

Kitchen Renovation Cost, in Detail

The kitchen is renovation's heavyweight: it combines carpentry, plumbing, electrical, gas, and ventilation in one small room. Typical 2026 budgets:

One more kitchen-specific warning: this is the wettest room in the house, so the plywood grade inside your cabinets matters more than the finish outside them. Insist on moisture-resistant cores — our BWP plywood guide explains exactly what to specify and why.

Bathroom Renovation Cost, in Detail

Per square foot, bathrooms are the most expensive space in any home — small rooms, dense with plumbing, tiling, and waterproofing. Typical budgets per bathroom:

Bedroom, Living Room & Other Spaces

Bedroom renovation: ₹1.5–4 L per room

Typically a wardrobe (₹80,000–2 L depending on size and finish), a headboard or panelled feature wall (₹30,000–80,000), false ceiling with cove (₹25,000–60,000), painting, and electrical updates. Add ₹40,000–1 L if flooring changes.

Living + dining renovation: ₹2–6 L

TV unit (₹50,000–1.5 L), false ceiling with layered lighting (₹50,000–1.2 L), feature wall (₹30,000–1 L), crockery unit, painting, and switches/points. This zone rewards spending on lighting more than on any single furniture piece.

Frequently forgotten line items

• Balconies: deck tiles, seating, and greenery — ₹30,000–1 L per balcony.
• Pooja unit: ₹25,000–80,000 depending on carving and back-panel work.
• Utility area: washer plumbing, storage, and dado tiling — ₹20,000–60,000.
• Main door refurbishment: polish or replacement — ₹8,000–60,000.
• Safety/handover items: deep cleaning, pest treatment, touch-ups — ₹10,000–25,000.

The 7 Factors That Swing Your Cost Most

1. Age of the property. Homes older than 15 years usually need full electrical rewiring (old wiring can't handle modern loads) and plumbing replacement — a ₹1.5–4 L layer newer flats skip.
2. Whether wet areas move. Relocating kitchens or bathrooms multiplies civil and plumbing cost, and in apartments may not be permitted at all.
3. Material grade. The essential-to-premium jump adds 30–60% per item — worth it in kitchens and master wardrobes, rarely in guest rooms.
4. Flooring decisions. Laying new tile over old (where feasible) costs a fraction of breaking and re-laying — but raises floor height. Full re-flooring for a 2BHK: ₹1.5–4 L.
5. Society rules & access. Restricted work hours, no service lift, debris rules, and refundable deposits all extend timelines and labour cost in gated communities.
6. Living in vs moving out. Occupied renovations run 15–25% slower. Compare that cost with two months' rent nearby before deciding.
7. Scope creep. The famous "while we're at it..." Every mid-project addition is priced without competition and delays everything behind it. Freeze scope before demolition day.

Hidden Costs: The Post-Demolition Surprises

These are the items that most commonly appear after the quote is signed. Ask about every one of them upfront — and read our full guide to hidden costs in home interiors for the new-interiors equivalents:

• Debris disposal beyond estimate — old flats often yield 30–50% more debris than assumed.
• Seepage & waterproofing repairs discovered behind bathroom and kitchen tiles.
• Termite treatment if trails are found during demolition (₹8,000–25,000).
• Electrical load upgrade — new ACs and appliances may need a sanctioned-load increase and new MCB distribution.
• Society deposits & charges — refundable, but they lock up ₹10,000–50,000 of cash flow.
• Furniture shifting & storage during work (₹15,000–60,000 for a typical 2BHK over two months).
• GST — confirm whether every quote you compare includes it.
• Deep cleaning & touch-up at handover, often excluded from base quotes.

10.10 Ways to Cut Renovation Cost — Without Cutting Corners

1. Keep wet points where they are. The single largest saving available.
2. Renovate in the right order, once. Civil → plumbing/electrical → waterproofing → tiling → carpentry → painting. Out-of-order work gets redone.
3. Retile over existing floors where height and structure allow.
4. Refinish instead of replace — solid wood doors, good granite, and structurally sound wardrobe carcasses can be re-laminated or polished for 30–40% of replacement cost.
5. Spend by zone, not uniformly — premium in kitchen and master wardrobe, standard elsewhere (the hybrid logic from our essential vs luxury guide).
6. Buy sanitaryware and appliances during sale seasons and have the contractor install — but confirm warranty responsibility in writing first.
7. Freeze the design before demolition. Mid-project changes are the most expensive purchases you'll ever make.
8. Move out if the project exceeds 6 weeks — the speed gain usually beats the rent.
9. Get itemised quotes only. Lump-sum quotes hide both padding and omissions.
10. Never skip waterproofing, wiring, or ply grade to save money. These are the three savings that always return as bigger bills.

Timelines & a Safe Payment Structure

For a stage-by-stage walkthrough of what happens when, see our interior design timeline guide.

Payment structure that protects you

A fair, milestone-linked schedule looks like: 10% booking → 40% on material/factory order → 40% on delivery and installation milestones → 10% on snag-free handover. Walk away from anyone demanding 70–80% before work begins, and hold that final 10% until every snag on your punch list is closed.

How we compiled these figures

Cost ranges reflect quoted and executed renovation projects in the Bangalore and Hosur market as of Q2–Q3 2026, at prevailing material, labour, and civil-work rates. Ranges are intentionally wide because renovation cost depends heavily on property age and condition — factors invisible until demolition.

This article is general guidance, not a quotation. For numbers specific to your home's age, layout, and condition, request an itemised estimate after a site visit — no renovation quote given without seeing the property should be trusted as final.
