WPC and SPC are both sold as "waterproof flooring" in India. Both use a click-lock system. Both look like wood. Both are positioned as alternatives to laminate in wet or humid areas. So what's actually different — and which one should you choose? The short answer is: they're designed for completely different problems, and buying the wrong one is a surprisingly easy mistake.
The Core Difference: What's Inside
The name tells you everything:
- WPC = Wood Plastic Composite. The core is a foamed polymer mixed with wood fibre. This makes it lightweight, slightly soft underfoot, and genuinely comfortable to stand on for hours. The foam structure also means it absorbs subfloor imperfections without cracking.
- SPC = Stone Plastic Composite. The core is a compressed mix of limestone powder and PVC. It's dense, rigid, dimensionally extremely stable, and harder underfoot. The stone content makes it heavier and more resistant to temperature-driven expansion and contraction.
Both have a vinyl wear layer on top — that's what makes them waterproof at the surface. The difference is entirely in the core behaviour.
How They Perform in Indian Conditions
| Factor | WPC | SPC |
|---|---|---|
| Monsoon humidity | Good — foam core absorbs minor expansion | Excellent — stone core barely reacts to moisture |
| Summer heat (45°C+) | Can soften/warp if left in direct sun | Better heat resistance; still needs expansion gaps |
| Comfort underfoot | Noticeably softer and warmer | Harder, colder — closer to tile feel |
| Impact resistance | Good — foam absorbs minor impacts | Less forgiving of dropped heavy objects |
| Subfloor tolerance | Forgiving of minor unevenness | Needs flatter subfloor — cracks under flex |
| Price (India, 2026) | ₹90–150/sqft | ₹80–140/sqft (slightly cheaper per sqft) |
Where Each Actually Belongs in an Indian Home
Choose WPC for: Living rooms, bedrooms, and any space where you'll be standing for long periods or walking barefoot. The foam core makes it noticeably more comfortable on hard Indian concrete subfloors. Also better for older buildings with uneven subfloors that can't be levelled perfectly.
Choose SPC for: Kitchens, laundry areas, commercial spaces, and any room that sees frequent wet mopping. The rigid stone core handles water pooling better than WPC's foam, which can eventually absorb water if the wear layer scratches through. SPC also outperforms in rooms with AC running 12+ hours a day — the aggressive temperature cycling that causes WPC to micro-expand and contract over time.
The Wear Layer Question
Both WPC and SPC live or die on their wear layer thickness. In India, a lot of mid-market product ships with 0.3mm wear layers — this is borderline. Aim for 0.5mm minimum for residential use, 0.7mm+ for kitchens and commercial. The wear layer thickness is where brands cut corners most aggressively, and it's where the product starts failing first in Indian footwear and wet-mop conditions.
Summary Recommendation
If you're choosing between WPC and SPC for a typical Indian 2BHK: use SPC in the kitchen and bathrooms, WPC everywhere else. If budget is tight and you can only pick one: SPC wins for its dimensional stability in India's climate extremes. But if you care about how the floor feels to walk on, especially barefoot in bedrooms — WPC is the better experience.
