3BHK Renovation Cost in Bengaluru 2026: Full Breakdown by Room and Package

The 3BHK renovation cost in Bengaluru in 2026 usually falls between ₹6 lakh and ₹35 lakh, and where your home lands in that range depends on its age, how much hidden plumbing and wiring needs replacing, and the finish level you choose. If you own a 1,300 to 1,800 sq ft apartment in Jayanagar, Indiranagar, HSR Layout or Malleshwaram that was built in the 1990s or 2000s, this guide breaks the numbers down room by room and package by package, so you can plan a realistic budget before you call a single contractor.

Quick answer: For a typical 1,500 sq ft Bengaluru 3BHK, expect roughly ₹6 to 10 lakh for a basic refresh (painting, minor repairs, one bathroom), ₹12 to 20 lakh for a mid-range renovation (new kitchen, two or three bathrooms, rewiring, flooring in key rooms), and ₹22 to 35 lakh or more for a premium overhaul with full flooring, modular wardrobes, false ceilings and layout changes. Older homes with concealed leakage or aluminium wiring sit at the higher end of each band.

3BHK Renovation Cost in Bengaluru 2026: Overview

Renovation is different from new interiors. When you move into a new flat, the walls are dry, the pipes are new and the wiring is under warranty. When you renovate a 20 or 25 year old home, part of your budget goes into things you will never see: replacing corroded GI pipes, fixing seepage behind tiles, upgrading the electrical load for air conditioners and induction cooktops, and correcting cracks that came from years of monsoon expansion and contraction.

That is why a quote for the 3BHK renovation cost in Bengaluru can look very different from a quote for new interiors in a similar sized flat. A fair way to think about it is in three layers:

• Civil and services layer: demolition, plumbing, electrical, waterproofing, plastering and flooring. This is usually 35 to 50 percent of the total in older homes.
• Interior layer: modular kitchen, wardrobes, TV unit, false ceiling, doors and windows. Usually 35 to 45 percent.
• Finishing layer: painting, lighting fixtures, sanitaryware, accessories and deep cleaning. Usually 15 to 20 percent.

Measured per square foot, the 3BHK renovation cost in Bengaluru in 2026 is roughly ₹450 to ₹700 per sq ft for basic work, ₹800 to ₹1,300 per sq ft for mid-range work, and ₹1,500 to ₹2,300 per sq ft or more for premium work, measured on carpet area. If you want a city-wide view across home sizes, our home renovation cost guide for Bangalore 2026 covers 1BHK to independent houses.

3BHK Renovation Cost in Bengaluru by Package

Most homeowners find it easier to start with a package and then adjust. The table below shows typical ranges for a 1,400 to 1,600 sq ft 3BHK apartment. These are indicative 2026 market ranges, not fixed prices, and a site visit always changes the final figure.

A useful rule: if your home was built before 2005 and has never had its plumbing replaced, budget from at least the middle of the mid-range band. In our experience, the 3BHK renovation cost in Bengaluru for such homes rarely stays in the basic band once the old tiles come off.

If your home is smaller, the 2BHK home renovation cost in Bangalore guide gives the equivalent numbers.

Room-by-Room Cost Breakdown

Breaking the 3BHK renovation cost in Bengaluru into rooms helps you decide where to spend and where to hold back. The figures below assume mid-range materials from reputed brands.

Kitchen

The kitchen usually takes the biggest single share of the 3BHK renovation cost in Bengaluru. In older Bengaluru flats, the kitchen often has a cement platform with a Cuddapah or granite top, a single steel sink and an exhaust fan hole. Converting this to a modular kitchen with a chimney, a tall unit and proper under-counter plumbing is where most of the money goes. Choosing BWP plywood over MDF for base cabinets near the sink is worth the extra 10 to 15 percent. For a deeper dive, read our kitchen and bathroom renovation guide for Bangalore 2026.

Bathrooms

A 3BHK usually has two or three bathrooms, and they are the main source of leakage complaints from the flat below. Never re-tile a bathroom without redoing the waterproofing and checking the floor trap and the slope. A bathroom done properly costs more upfront, but a leaking bathroom can cost you a neighbour's ceiling repair and months of association follow-ups.

Bedrooms and Living Areas

Wardrobes drive bedroom costs and can swing the 3BHK renovation cost in Bengaluru by several lakh. A sliding wardrobe with laminate finish costs much less than a lacquered glass or PU finish wardrobe. In the living room, false ceilings and lighting change the feel of a dated home the most for the money spent.

Hidden Costs in Older Bengaluru Homes

The gap between the first quote and the final bill usually comes from what is found after demolition. If you are estimating the 3BHK renovation cost in Bengaluru for a home built in the 1990s or early 2000s, keep a contingency of 10 to 15 percent for these items:

Homes that are older still, or independent houses, have their own patterns. Our old house renovation guide for Bangalore explains structural checks for those properties.

What Pushes the Price Up or Down

Two families with identical floor plans can end up with very different bills. These are the factors that move the 3BHK renovation cost in Bengaluru the most:

1. Age and condition of services: A home where plumbing and wiring are reusable can save ₹2 to 4 lakh.
2. Flooring choice: Overlaying new tiles on old ones is cheaper but raises the floor level and can cause door clearance problems. Full removal costs more but is cleaner.
3. Material brands: The difference between a local laminate and a branded one, or between entry-level and premium sanitaryware, can be 30 to 50 percent per item.
4. Layout changes: Moving a kitchen, opening a wall or shifting a bathroom adds plumbing, structural checks and association approvals.
5. Floor and access: A tenth-floor flat with a small service lift and restricted working hours costs more in labour and logistics than a ground-floor flat.
6. Whether you live in during work: Phased work takes longer and adds protection and cleaning costs.
7. Season: Waterproofing, external painting and terrace work are best done between November and April, before the monsoon. Demand peaks before Deepavali, which can push labour rates up.

Building materials follow published standards. If you want to understand grades of cement, tiles or electrical cables, the Bureau of Indian Standards lists IS codes you can ask your contractor to confirm on product labels.

Renovation Timeline and Step-by-Step Process

Time is money on site, so the schedule affects the 3BHK renovation cost in Bengaluru directly. A mid-range project usually takes 8 to 12 weeks from demolition to handover. Planning and design add 2 to 4 weeks before that. Here is a typical sequence:

1. Week 0 to 2, site survey and design: Measurements, moisture checks, electrical load assessment, layout and 3D designs, material selection.
2. Week 2 to 3, quotation and approvals: Itemised BOQ, association permission letter, work schedule and payment milestones agreed.
3. Week 3 to 4, demolition: Old tiles, kitchen platform, bathroom fittings and wardrobes removed. Debris cleared as per association rules.
4. Week 4 to 6, services: Plumbing in CPVC/UPVC, electrical conduits and wiring, AC piping, waterproofing in bathrooms and balconies with a 24 to 48 hour ponding test.
5. Week 6 to 8, civil finishes: Flooring, wall tiling, plastering repairs, false ceiling framing.
6. Week 7 to 10, carpentry: Factory-made modular units installed. Site carpentry for custom pieces.
7. Week 9 to 11, painting and fixtures: Putty, primer, paint, light fittings, sanitaryware, switches.
8. Week 11 to 12, snagging and handover: Defect list, corrections, deep cleaning and warranty documents.

Painting is often the last major item and the one people try to time with festivals. If that is your plan, our painting cost before Deepavali guide explains how to book early.

Apartment Association Rules and Approvals

Most Bengaluru apartment associations have written renovation rules, and ignoring them can stop work halfway. Before you finalise the 3BHK renovation cost in Bengaluru with any contractor, confirm these points with your association or facility manager:

• Working hours: Commonly 9 am to 6 pm on weekdays, with noisy work like drilling and breaking restricted to specific hours. Sundays and public holidays are often off limits.
• Refundable deposit: Many associations ask for a deposit, often ₹10,000 to ₹50,000, refunded after inspection of common areas.
• Lift usage: Material movement through the service lift only, with lift padding and time slots.
• Debris disposal: Debris bagged and removed by your contractor, never left in corridors or basement.
• Structural restrictions: No cutting of beams, columns or shear walls. Any wall removal needs a structural engineer's opinion.
• Facade rules: Balcony enclosures, grill changes and outdoor AC unit placement often need approval to keep the building uniform.

For independent houses where you plan structural changes or additional floors, check plan sanction requirements with BBMP before work begins.

Mistakes to Avoid

These are the mistakes that most often inflate the 3BHK renovation cost in Bengaluru for families in older apartments:

1. Comparing quotes by the total only: A lower total often hides lower-grade plywood, thinner tiles or missing waterproofing. Compare item by item.
2. Skipping the ponding test: Bathroom and balcony waterproofing must be tested with standing water before tiling. Skipping this saves a day and can cost lakhs later.
3. Tiling over old plumbing: If pipes are more than 15 years old, replace them while the walls are open. Breaking new tiles later is far more expensive.
4. Ignoring electrical load: Adding three ACs and a geyser on old wiring is a fire risk. Ask for a load calculation and a new distribution board.
5. No written scope or payment schedule: Every item, brand and finish should be in writing, with payments linked to completed stages.
6. Starting waterproofing in June: Plan wet-area and external work for the dry months. Monsoon work rarely cures properly.
7. Underestimating the timeline: Add two weeks of buffer for material delays and association restrictions.

Choosing the right team prevents most of these. Our guide to the best home renovation contractors in Bangalore lists the questions to ask before you sign.

How to Save Without Cutting Corners

Reducing the 3BHK renovation cost in Bengaluru is about spending in the right places, not buying the cheapest material. Practical ways to save:

• Retain what works: Good quality granite floors, solid teak doors and sound window frames can be polished and reused.
• Prioritise wet areas: Spend on kitchen and bathroom waterproofing and plumbing first. Décor can be upgraded later.
• Standardise sizes: Using standard modular sizes reduces carpentry waste and cost.
• Use laminate where it matters less: Laminate in kids' rooms and lacquer or acrylic only where it is visible every day.
• Bundle work: One contractor handling civil, electrical, plumbing and interiors usually costs less than four separate vendors, and avoids blame-shifting.
• Book in the off-season: January to April often has better labour availability than the pre-Deepavali rush.

A single team that handles design, civil work and interiors makes this easier. You can see how we structure this on our home renovation services page.

Frequently Asked Questions

What is the average 3BHK renovation cost in Bengaluru in 2026?

For a 1,400 to 1,600 sq ft apartment, most mid-range renovations cost between ₹12 lakh and ₹20 lakh. A basic refresh can be ₹6 to 10 lakh, while a premium overhaul can go beyond ₹30 lakh.

How much does it cost per sq ft to renovate a 3BHK in Bangalore?

Roughly ₹450 to ₹700 per sq ft for basic work, ₹800 to ₹1,300 per sq ft for mid-range and ₹1,500 to ₹2,300 or more for premium finishes, on carpet area.

How long does a full 3BHK renovation take?

Plan for 8 to 12 weeks of site work for a mid-range scope, plus 2 to 4 weeks of design and approvals. Premium projects can take 4 months.

Can I renovate my 3BHK while living in it?

Yes, if the work is phased room by room. It takes longer and needs dust protection, but many Bengaluru families do it. Kitchen and bathroom phases are the hardest to live through.

Do I need BBMP approval to renovate an apartment?

Internal renovation without structural changes generally does not need BBMP plan approval, but your apartment association's written permission is almost always required. Structural changes or additions in independent houses need proper approvals.

How much contingency should I keep?

Add 10 to 15 percent to your estimated 3BHK renovation cost in Bengaluru for homes older than 15 years. Hidden plumbing, seepage and wiring issues are the usual reasons.

Is it cheaper to renovate or to buy a new 3BHK?

Renovating is usually far cheaper than buying a new flat in a similar Bengaluru locality, and you keep your neighbourhood, schools and commute. It makes sense when the building structure is sound.

Which rooms should I renovate first if my budget is limited?

Spend the first part of your 3BHK renovation cost in Bengaluru on bathrooms and the kitchen, because leakage and plumbing problems get worse with time. Bedrooms and living areas can be upgraded in a second phase.
