Of all flat sizes, a 3BHK interior budget varies the widest — there’s more area, more rooms, often a third bathroom, and more scope for premium finishes, so the gap between a sensible mid-range fit-out and a high-end one is large. As with any flat, the per-square-foot rate hides the detail. What helps is a room-by-room view of where a 3BHK budget goes and what scales as you move up from a 2BHK. This guide lays it out.

The figures here are indicative current market ranges for Thane and the wider MMR — not Jyani’s quote — your exact cost depends on scope, materials and the flat’s condition, and is confirmed only after a free site visit and a review of your requirements.

What scales from a 2BHK to a 3BHK

Moving up isn’t simply “add 50%”. The extra bedroom adds a wardrobe, storage and lighting; the often-larger living/dining supports a more layered ceiling and a bigger feature wall; and a third bathroom adds a full waterproofing-and-finish line. Painting, flooring and electrical scale with the extra area. The kitchen, interestingly, doesn’t always scale much — a 3BHK family kitchen may be similar in cost to a well-specified 2BHK kitchen. If you’re comparing the two, our 2BHK interior design cost in Thane West guide sits alongside this one.

The premium-finish factor

3BHK projects are where premium finishes most often enter the budget — acrylic or veneer kitchen shutters, a quartz counter, engineered-wood flooring in bedrooms, layered cove ceilings, and more lighting. Each is a legitimate choice, but together they can move a 3BHK from mid-range to high-end. The way to stay in control is to decide where premium genuinely matters to you (often the kitchen counter and the living room) and where standard is fine, rather than upgrading everywhere by default.

How to budget realistically

Decide scope and civil inclusion first, then get an itemised, room-wise BOQ from a site visit. Lock material selections early — on a 3BHK, with more rooms and decisions, scope creep after demolition is the most common reason budgets run over.

Frequently Asked Questions

How much does a 3BHK interior cost in Thane? It varies the widest of any flat size, depending on area, finish level and civil scope. This guide breaks the budget down room by room with indicative ranges; the exact figure comes from an itemised BOQ after a site visit.

Is a 3BHK interior just 50% more than a 2BHK? Not exactly — the extra bedroom, often-larger living area, third bathroom and more painting/flooring/electrical all add, while the kitchen may not scale much. It’s better budgeted room by room than by a flat percentage.

Where do 3BHK budgets most often go premium? In kitchen shutters and counter, bedroom flooring, layered ceilings and lighting. Choosing where premium genuinely matters — rather than upgrading everywhere — is how to keep control.

Which part of a 3BHK costs the most? Usually the modular kitchen, then wardrobes and furniture across three bedrooms. Bathrooms scale with the count; civil work is the swing factor in resale flats.

Can I phase a 3BHK renovation? Yes — phasing suits larger projects with cash-flow needs, with phase breaks set so they don’t compromise sequencing (all wet work before finishes, for example).
