Both look like iron rods. Only one is real steel.

Every bathroom has a hollow space under the floor where the pipes sit. If that space is filled with broken bricks and stones instead of clean sand, water finds a way down.

- Crystalline waterproofing membraneA proper waterproof coating from Dr. Fixit or Fosroc. Engineered to last decades
- Brand and coat count in your contractWritten before any tile is laid

Type the total quote your contractor gave you. We compare it against the realistic range for your home and tell you where the gap likely hides.
Estimated raw materials for your build. Take this to any supplier or contractor for verification. If a quote uses dramatically less than this, ask why.
You chose Comfort. Here is what changes if you go up or down.
Same plot, same area, same floors. Only the materials and finishes change.
All numbers above update as you change this.
- Primary TMT steel. Brand named in your contract. No rerolled bars.
- Structural Engineer drawings. Signed, sealed, and yours to keep.
- Electrical and plumbing coordinated. Pipe and wire routes drawn together on paper before any slab is cast.
- Crystalline waterproofing. Dr. Fixit or Fosroc. Brand and method in writing.
- Verified M-sand and concrete mix. Sand quality checked on site, mix recipe agreed before every pour.
- Finolex or Polycab FRLS wiring. Flame Retardant Low Smoke. Brand named in your contract.

The gap is not because a contractor lied. It is because ₹1,800 is a stripped-down base rate. It assumes rerolled steel, no Structural Engineer, skipped waterproofing, and the cheapest wire and paint. Those are the choices that make ₹1,800 possible.
