The Ultimate Guide to Flat Renovation in Mumbai (2026)

Buying a resale flat or receiving possession of a new flat in Mumbai is a huge milestone. However, transforming it into your dream home requires meticulous planning and a reliable civil contractor. Here is the most realistic breakdown of civil and interior renovation costs in Mumbai for 2026.

1. Civil Alterations and Flooring Cost

In Mumbai, maximizing space is essential. Many homeowners opt to break walls to open up the kitchen or merge balconies. Once alterations are done, changing the flooring to modern large-format vitrified tiles (e.g., 2x4 ft or 32x32 inch) is highly recommended.

  • Demolition and Debris Removal (Kachra): ₹15,000 to ₹25,000 (Mumbai has strict rules and high costs for debris dumping).
  • New Flooring (Material + Labor): ₹100 to ₹150 per sq.ft., depending on tile quality. For a standard 1BHK (approx. 400 sq.ft. carpet), flooring costs around ₹50,000 to ₹70,000.

2. Bathroom Remodeling & Waterproofing

Leaking bathrooms are the biggest nightmare in Mumbai societies. A complete bathroom overhaul includes removing old tiles, chemical waterproofing, new concealed plumbing (CPVC), and fitting designer tiles and sanitaryware.

Cost per Bathroom: ₹60,000 to ₹90,000. Never compromise on waterproofing quality in Mumbai!

3. Modular Kitchen Construction

Breaking the old builder-provided platform and building a new L-shaped or parallel Granite/Quartz platform with wall tiles (Dado) and modular baskets (Marine Plywood + Acrylic finish).

Cost: ₹80,000 to ₹1.5 Lakhs based on finishes and accessories.

4. Painting and POP/False Ceiling

Applying Birla Putty, followed by a premium washable plastic paint (like Asian Paints Royale), combined with a modern POP false ceiling with hidden LED cove lights.

Cost: ₹60,000 to ₹1 Lakh for a 1BHK flat.

Total 1BHK Renovation Estimate

A complete, end-to-end standard renovation for a 1BHK in Mumbai typically costs between ₹3 Lakhs to ₹5 Lakhs. A 2BHK renovation ranges from ₹5 Lakhs to ₹8 Lakhs.
