3BHK Interior Design Cost in Bangalore | Suntew

Furnishing a 3BHK in Bangalore is the most-asked-about, least-clearly-answered cost question in the city's interior design market, mostly because a '3BHK' can mean anything from 1,050 to 1,900 sq ft depending on the builder, the layout, and whether anyone's quoting you carpet area or the more generous built-up area.

We'll give you the direct number first, then walk through exactly where it goes and why two quotes for the 'same' flat can differ by lakhs. Every figure below reflects typical 2025-26 market rates for Bangalore 3BHK interiors at this scope, priced on a fixed-price basis.

How much does a 3BHK cost to furnish in Bangalore?

A complete 3BHK in Bangalore, 1,200 to 1,800 sq ft, runs Rs.4.5 to Rs.11 lakhs depending on finish grade. That's the number people search for, so let's start there before we get into where it actually goes.

It's a wide range because a 3BHK isn't one job, it's five or six smaller jobs stacked together: three bedrooms with different owners' tastes, a kitchen that has to work daily, a living-dining zone that does the entertaining, and usually a study or a guest room that gets treated as an afterthought until someone actually has to work from home in it. Below is where the money typically goes, room by room, at 2025-26 Bangalore market rates.

What does each room actually cost?

Add these up at the standard-finish column and you land around Rs.4.5 to 5 lakhs. Premium finish, meaning better plywood grade, branded hardware, and more false ceiling and lighting work, pushes it to Rs.9 to 11 lakhs. Most Suntew clients land in between, closer to Rs.6.5 to 7.5 lakhs, because they upgrade the kitchen and master bedroom and keep the third bedroom simple.

Why do quoted prices for '3BHK interiors' vary so wildly online?

You'll see quotes anywhere from Rs.3 lakhs to Rs.15 lakhs for what's called a '3BHK package,' and it's not because someone's lying, it's because '3BHK' doesn't mean a fixed size. A big part of the confusion is builders historically sold flats on super built-up area, which can be 25 to 30% larger than the space you actually get to walk on.

The Real Estate (Regulation and Development) Act, 2016 changed this. Under RERA, developers must now disclose and price based on carpet area, defined as the net usable floor area excluding external walls but including internal partition walls, not the inflated super built-up figure. So a '1,500 sq ft 3BHK' by super built-up area might have a carpet area closer to 1,050 to 1,150 sq ft, and that's the number that actually determines how much interior work you need. Before you compare quotes across companies, always ask whether their per-sq-ft rate is based on carpet area or built-up area. It's the single biggest reason two '3BHK quotes' can differ by 40%.

What's included in a 'complete' 3BHK package, and what usually isn't?

1. Modular kitchen — cabinets, counter, and basic appliances cutouts are standard; the chimney, hob, and sink itself usually aren't, unless you specifically ask.
2. Wardrobes in all three bedrooms — sliding or openable shutters with internal fittings; mirror panels are often a separate line item.
3. False ceiling — typically the living room only in a standard package; bedroom ceilings cost extra unless you push for full coverage.
4. Painting — two coats of emulsion is standard; texture or accent-wall finishes are priced separately.
5. Electrical and plumbing points — shifting or adding new points isn't included in most fixed packages and gets billed as a change request, so flag anything you want moved during the design stage, not after work starts.
6. TV unit and study table — these are frequently 'optional add-ons' in package pricing, not core inclusions, so check the itemised quote line by line.

Owner-occupied 3BHK vs a rental or resale flat: does the spend change?

Yes, and it should. If you're moving in for the long haul, put the money into the kitchen carcass, wardrobe hardware, and anything that's expensive to redo later. Cosmetic things like an accent wall or a fancy pendant light are cheap to change in five years; a swelling plywood shutter isn't.

If it's a rental 3BHK, the calculus flips. Tenants respond to how a flat photographs and feels on the first walkthrough, not to what brand of hinge is inside the cabinet. A well-lit living room, a clean modular kitchen, and decent wardrobes across all three bedrooms let you charge 15 to 20% above a bare-shell rental in most Bangalore micro-markets, and you don't need premium-grade everything to get there.

Where do most 3BHK budgets actually blow past the estimate?

Almost never on the kitchen or the wardrobes, since those are quoted upfront and locked into a fixed-price contract if you insist on one. It's the things people don't think to ask about at the quotation stage: shifting a switchboard after the electrician's already wired the flat, adding a loft over a wardrobe once you see how little storage you actually have, or deciding halfway through that you want the third bedroom's plain shutters upgraded to match the master bedroom.

Our advice, and it costs nothing: walk through the 3D design with your family before signing off, room by room, and ask 'will I regret not doing this now' for anything you're on the fence about. Change requests after work starts always cost more than the same item priced in at the start.

What should you ask before signing a 3BHK interior contract?

Most disputes in 3BHK projects trace back to a handful of questions nobody asked at the start. Before you sign anything, get clear, written answers to these:

1. Is the quote based on carpet area or built-up area? — as covered above, this single line item explains most of the price gap between competing quotes for the 'same' flat.
2. What plywood grade is specified, and is it named on the invoice? — 'branded plywood' means nothing without a grade. Ask for BWR or better in writing, not just verbally at the site visit.
3. Is the price fixed, or does it change if material costs rise mid-project? — a genuinely fixed-price contract protects you from mid-project cost hikes; a 'quotation' or 'estimate' usually doesn't.
4. What's the payment schedule tied to? — payments linked to actual work milestones, like carcass completion or shutter fixing, protect you far better than a schedule tied purely to calendar dates.
5. Who handles a defect found after handover, and for how long? — get the warranty period and what it covers, hardware, plywood, or both, in writing before work starts, not after something's already gone wrong.

One more: ask whether the quoted price includes GST. Interior work in India is taxed under GST, with the exact rate depending on contract structure — check current classifications on the CBIC GST portal if you want to verify before signing. None of these questions should make a designer defensive. If they do, that's information too.
