Stone-composite core: 100% waterproof and dimensionally rock-steady. Typical installed cost, durability, where it works and how to care for it.
SPC stands for stone-plastic composite: limestone powder blended with PVC and stabilizers, extruded into a dense, rigid core. Because the core contains no organic material, it cannot swell, rot, or support mold, and it barely moves with temperature — the two properties that make SPC the default recommendation for kitchens, baths, basements and rental properties. It is denser and thinner than WPC, so it telegraphs subfloor imperfections and feels harder and louder underfoot unless it carries an attached acoustic pad.
The clear top film — the durability spec that matters most. 6 mil: light residential. 12 mil: busy homes and pets. 20–30 mil: commercial. 6 mil and 20 mil products can look identical in the box.
SPC is stone-filled, rigid, thin, dent-resistant and cheaper. WPC is foamed and warmer, softer and quieter, but dents more easily under point loads like refrigerator legs.
IXPE or cork pad bonded to the plank. Adds meaningful acoustic dampening and comfort, and saves an install step, but hides less subfloor unevenness than people expect.
Aluminum-oxide or ceramic-bead additives in the top coat raise scratch resistance substantially. Ask specifically whether the wear layer is enhanced.
Angle-angle, angle-tap and drop-lock. Quality of the milling matters more than the brand — a poorly milled click joint will peak and separate.
Reputable current products are phthalate-free and FloorScore certified for indoor air quality. Cheap imports frequently are not — ask for documentation.
| Wear layer | 6–30 mil |
|---|---|
| Total thickness | 4–8 mm |
| Waterproof | Yes — core and surface |
| Install | Floating click, glue-down commercial |
Wear layer is the whole ballgame. 12 mil minimum for a family home, 20 mil for anything commercial. Below 8 mil is a rental-grade product.
Each feature paired with the benefit it delivers. A spec on its own tells you nothing about whether it is worth paying for.
No organic content whatsoever, so it cannot swell, rot or feed mold. A burst supply line is a mopping job, not a replacement job.
Commercial-grade abrasion resistance in a residential product. The spec that decides whether a floor looks new in year eight or tired in year three.
The rigid core barely reacts to temperature, so it can run continuously from a sunny kitchen through to a north-facing hall without transition strips.
Raises scratch resistance sharply — the practical difference between a floor that shows every claw mark and one that does not.
Goes over existing tile, plywood or a flat slab with no adhesive, so an occupied house can be floored room by room.
Drawn from the same ratings used everywhere else on this site, so this cannot flatter the product beyond what the comparison table says.
The specifications below decide how this floor performs. Ask for them in writing — a sample board and a price per square foot do not tell you any of it.
Luxury Vinyl Plank — SPC (Rigid Core) runs $4.00–$11.00 per square foot installed in 2026 — $2.00 to $6.00 for material and $2.00 to $5.00 for professional labor. Spread across an expected 15 to 25 year service life that works out near $0.38 per square foot per year. Regional variation of 20 to 40% is normal, and demolition, subfloor prep and trim are extra.
15 to 25 years, assuming it went into an appropriate room over a properly prepared substrate and gets the maintenance it needs. Wear layer is the whole ballgame. 12 mil minimum for a family home, 20 mil for anything commercial. Below 8 mil is a rental-grade product.

Yes — luxury vinyl plank — spc (rigid core) is unaffected by water, which is why it works in bathrooms, laundries and below grade. Note that a waterproof material does not make a waterproof floor: water can still travel through seams to the subfloor beneath.
Sweep or vacuum (beater bar off) regularly. Damp-mop with a pH-neutral vinyl cleaner as often as you like — it is waterproof. Critically: never use rubber-backed mats — vinyl reacts with rubber and stains permanently.
Same family first, then products with a similar look from other families.
Foamed core: warmer, quieter and softer than SPC — and thicker.
Seamless, welded, genuinely impermeable — the healthcare standard.
Cheap to buy, expensive to keep. Know the lifecycle math.
