Quick answer:
Typical range: ₹15 lakh to ₹25 lakh for a 3 BHK, according to Housiey’s 2026 guide. That figure covers India, and the same guide ranks Mumbai as the costliest city, so expect your quote to sit in the upper half.
Biggest line item: the kitchen, which usually takes 20% to 25% of the total budget, per Housiey.
Easy-to-miss extras: 18% GST on modular components, civil work, society deposits, and a designer fee of 10% to 15% at some firms.
How Much Does a 3 BHK Interior Cost in Mumbai?
Start with two reference points, then compare them with a real project.
Now add a Mumbai example. RSpace’s completed projects page lists a 1,200 sq ft 3 BHK in Andheri West at ₹18 lakh to ₹22 lakh. The scope covers a complete modular kitchen, wardrobes, and a TV unit with premium finishes. The company’s FAQ also says full home interiors start from ₹15 lakh.
Divide the project band by 1,200 sq ft and you get roughly ₹1,500 to ₹1,830 per sq ft. That is my own arithmetic. It sits below Housiey’s Mumbai rate, and the gap is a reminder that per sq ft prices depend on scope. A figure that includes false ceilings, civil work, and loose furniture runs higher than one for modular woodwork alone. Use per sq ft numbers as a sanity check, never as a quote.
Full Home Interior Cost: Where a ₹20 Lakh Budget Goes
Housiey says kitchens usually take 20% to 25% of the total. The rest of this split is a planning guide I built from published unit rates and listed project bands. Adjust it to your own plan.
The shares overlap, and the midpoints add up to about 100%. Here is what sits inside each line.
Kitchen: ₹4 lakh to ₹5 lakh
Design Cafe puts fully modular kitchens in Mumbai at ₹3.5 lakh to ₹6 lakh in its March 2026 guide. The RSpace project listing shows a kitchen band of ₹4 lakh to ₹6 lakh. Finish drives most of the gap. Housiey lists laminate at ₹1,400 to ₹2,000 per sq ft, acrylic at ₹2,000 to ₹3,000, and PU at ₹3,000 to ₹4,000.
Bedrooms and wardrobes: ₹6 lakh to ₹7 lakh
Wardrobes swing the total more than any other item. Picture three wardrobes, each 6 ft wide and 7 ft high. That is 126 sq ft of wardrobe. At Housiey’s rates, laminate costs about ₹1.3 lakh to ₹1.9 lakh, and sliding systems cost about ₹3.2 lakh to ₹4.4 lakh. Your finish choice alone moves the budget by ₹2 lakh or more.
For a fuller bedroom, RSpace lists a 320 sq ft master bedroom in Powai at ₹3 lakh to ₹4 lakh. It includes a floor-to-ceiling wardrobe, a walk-in closet, and a vanity. If your third bedroom becomes a study, the same page shows a 200 sq ft home office at ₹1.5 lakh to ₹2 lakh.
Living and dining: ₹3 lakh to ₹4 lakh
DesignCafe splits interiors into must-haves and good-to-haves. Must-haves include a TV unit and a small shoe rack. Good-to-haves add wall panelling, a foyer unit, and upgraded finishes. Most of your overspending risk lives in this list. Decide early which items you want now and which can wait.
Bathrooms: ₹1.6 lakh to ₹2.4 lakh
Housiey puts the average bathroom at ₹80,000 to ₹1.5 lakh. Two bathrooms therefore cost ₹1.6 lakh to ₹3 lakh. A luxury build costs more. RSpace lists a 180 sq ft bathroom in Juhu with Kohler fittings at ₹2.5 lakh to ₹4 lakh. If your flat has a third bathroom, add it to the plan.
False ceiling, lighting, and paint: ₹1.6 lakh to ₹2 lakh
Housiey lists gypsum ceilings at ₹90 to ₹150 per sq ft, POP at ₹70 to ₹120, and wooden ceilings at ₹250 to ₹450. Take 700 sq ft of gypsum ceiling. That costs about ₹63,000 to ₹1.05 lakh before lighting and paint.
What Pushes Your Price Up or Down
Five factors explain most of the difference between two quotes:
Finish grade. Premium finishes, fancy carpentry, and branded fittings raise cost the most, says DesignCafe.
Scope. A quote with civil and electrical work costs more than one without.
Room use. DesignCafe notes that a spare room used as a small den costs far less than one fitted with a wall bed and a study unit.
Mumbai itself. Labour and transport run higher here than in many cities, and society rules limit work hours.
Carpet area. More area means more materials, storage, and labour.
Hidden Costs Mumbai Buyers Miss
The quote you sign rarely equals the money you spend. Watch for these items:
Civil work for plumbing or gas line changes
Electrical upgrades
Society deposits and permissions
Temporary relocation during work
An exhaust duct for a ductable chimney
18% GST on modular components
A designer fee, which HomeLane says often runs 10% to 15% of project cost
Do the math on GST. Say ₹15 lakh of a ₹20 lakh quote covers modular components. GST then adds ₹2.7 lakh. Ask whether your quoted figure already includes it. A 10% to 15% designer fee on ₹20 lakh would add ₹2 lakh to ₹3 lakh, so ask whether the fee sits inside the package.
7 Ways to Lower Your Full Home Interior Cost
Phase the work. Finish the kitchen, wardrobes, and bathrooms first. Add loose furniture later.
Use laminate inside cabinets. Spend on visible shutters instead.
Pick standard module sizes. DesignCafe says smart kitchen planning can trim costs by 15% to 25%.
Keep plumbing points where they are. Moving them adds civil work.
Mix modular units with simple carpentry. Odd corners often cost less this way.
Choose one showpiece zone. Put the panelling in the living room and keep other rooms simple.
Compare itemised quotes. Match finish, plywood grade, and hardware before you judge price.
What a Good 3 BHK Quote Should List
A clear quote leaves no guesswork. Check that it names:
Every room and what it includes
Finish and plywood grade for each item
Hardware brand and model
Civil, plumbing, and electrical work, priced separately
GST, shown clearly
Payment stages
Warranty length and coverage
Start date and completion timeline
Use a published vendor as a yardstick. RSpace’s FAQ states full-home timelines of 30 to 45 days after design approval, along with a 10-year warranty on modular products. Whoever you hire, ask for the same details in writing.
Next Steps
You now have the numbers to judge any 3 BHK quote. Here is a simple plan:
Measure each room and list what you need now versus later.
Set a total budget and keep 5% to 10% as contingency.
Request three itemised quotes with the same scope.
Compare them against the checklist above.
Visit a showroom and ask to see finished work.
If you want to test your numbers against a real home, RSpace’s full home interiors range and its Andheri West showroom give you a place to start. Knowing your full home interior cost before you sign is the surest way to avoid a mid-project surprise.
