Home Renovation Cost in Bangalore (2026)

Renovating a home in Bangalore is a different job from doing the interiors of a new flat. With a new flat you start from bare walls and known services. With a home that is ten, twenty or forty years old, you start with what previous owners left behind: wiring sized for a fridge and two fans, pipes that have scaled up inside, tiles laid over tiles, and a layout planned for a different way of living.

That hidden work is why renovation estimates vary so much. In 2026, a cosmetic refresh of a Bangalore flat can cost Rs 300 to Rs 600 per square foot. A full renovation, with new services, flooring, kitchen, bathrooms and carpentry, usually costs Rs 1,800 to Rs 3,500 per square foot of carpet area.

This guide explains what drives that range and how to plan a renovation that does not grow halfway through.

Three levels of home renovation

A cosmetic refresh changes how the home looks without opening walls or floors. It covers painting, new lights and fans, new switch plates, minor carpentry repairs, new curtains and perhaps a few shutters. For a 1,100 sq ft 2 BHK, that is roughly Rs 3.5 lakh to Rs 6.5 lakh.

A partial renovation targets the rooms that age worst: the kitchen and the bathrooms, plus electrical upgrades and painting. For a 2 BHK this usually costs Rs 8 lakh to Rs 15 lakh. It is the most common scope for flats bought resale in areas such as Jayanagar, JP Nagar, Koramangala and Indiranagar.

A full renovation strips the home back. It replaces the wiring and plumbing, re-does the floors, the kitchen and every bathroom, adds new wardrobes and storage, and often changes the layout by moving a wall or merging rooms. For a 1,100 sq ft flat that typically means Rs 20 lakh to Rs 38 lakh, and more for independent houses.

Room-by-room and trade-by-trade costs

These 2026 ranges are for a typical Bangalore apartment:

• Full electrical rewiring: Rs 1.5 lakh to Rs 3 lakh for a flat, and Rs 2.5 lakh to Rs 5 lakh for an independent house.
• Bathroom renovation, including waterproofing, plumbing, tiles and fittings: Rs 1.8 lakh to Rs 3.5 lakh per bathroom.
• Kitchen renovation with new cabinets: Rs 1.8 lakh to Rs 3.8 lakh, rising to Rs 6 lakh with new plumbing, wiring and tiles.
• Flooring: Rs 80 to Rs 240 per sq ft installed for vitrified tiles, plus Rs 25 to Rs 45 per sq ft to remove the old floor.
• Painting with putty and primer: Rs 18 to Rs 35 per sq ft of wall area.
• Wardrobes: Rs 65,000 to Rs 1.6 lakh each, depending on size and finish.
• False ceiling with cove lighting: Rs 90 to Rs 160 per sq ft.

Add 8 to 12 per cent for design, supervision and contingency. Renovations nearly always uncover something, and having a buffer is cheaper than stopping work to find money.

The hidden costs in older Bangalore homes

Wiring is the first. Homes built before the early 2000s were often wired with aluminium or thin copper conductors and no earth leakage protection. A modern household runs ACs, geysers, induction cooktops, chargers and a home office. Extending old circuits instead of replacing them is a false economy and a safety risk.

Plumbing is the second. Galvanised iron pipes corrode and scale from the inside, which is why water pressure drops in older flats. CPVC lines inside the walls, replaced while the tiles are off, solve the problem for decades.

Waterproofing is the third. Damp patches on a bedroom wall that shares a wall with a bathroom, or on a ceiling below a terrace, usually mean the original waterproofing has failed. Fix the source before painting, or the patch returns after the first monsoon.

Floor levels are the fourth. Many older homes have had new tiles laid over old ones, raising the floor until doors scrape. Proper removal costs more upfront but avoids trimming every door in the house.

Termites are the fifth. Bangalore's older layouts have a long history of termite trouble in wooden frames and built-in cupboards. An anti-termite treatment before new woodwork goes in costs a small fraction of the carpentry it protects.

Renovating an independent house versus a flat

Independent houses in older areas such as Basavanagudi, Malleshwaram, Rajajinagar and Jayanagar give you more freedom: you can change windows, add a room on the terrace, rework the staircase or re-do the facade. They also carry more risk, because the structure, the roof and the external walls are your responsibility.

Have a structural engineer look at the house before you plan any wall removal or vertical addition. Cracks over doors and windows, sagging lintels and dampness at the base of walls all need to be understood before the interior work is designed.

Flats are simpler but more restricted. You cannot touch structural walls or columns, external changes such as balcony enclosures often need the association's approval, and work hours and debris removal follow society rules.

How to keep a renovation on budget

Fix the scope in writing before work starts, with drawings and a bill of quantities that lists every item, its material and its rate. Most budget overruns come from decisions made on site.

Do the services first. Wiring, plumbing and waterproofing go in before tiles, carpentry and paint. Reversing that order is how renovations end up cutting new tiles to fix old pipes.

Choose materials before demolition. Tiles, sanitaryware, kitchen finishes and lights all have lead times. Waiting for a tile to arrive while the floor is open costs time and labour.

Phase if you need to. Many families renovate the kitchen and bathrooms first, then the bedrooms and living room a year later. It costs a little more overall because the team mobilises twice, but it spreads the spending.

How long a home renovation takes

A cosmetic refresh of a 2 BHK takes two to four weeks. A partial renovation with the kitchen and two bathrooms takes six to ten weeks. A full renovation of a flat takes three to five months, and an independent house with structural work can take six months or more.

If you plan to live at home during the work, add time. Most full renovations are easier and faster if the family moves out.
