SPC vs WPC Vinyl Flooring: Which One Should You Buy?

SPC (Stone Plastic Composite) and WPC (Wood Plastic Composite) are both 100% waterproof vinyl flooring options — but they are built differently, feel different underfoot, and perform differently depending on where you install them. The short answer: SPC is denser, more durable, and better for high-traffic or commercial-adjacent spaces; WPC is softer and warmer underfoot but less dimensionally stable. For most GTA homes — especially basements, kitchens, and main floors — SPC wins. Here's exactly why, with real numbers.
What Is SPC Vinyl Flooring?
SPC stands for Stone Plastic Composite. The core is made from a blend of limestone powder, polyvinyl chloride (PVC), and stabilizers — compressed into a rigid, dense plank. A typical SPC plank is 4–6mm thick at the core, with a printed wear layer on top and an attached underlayment on the bottom.
Because the core is stone-based, SPC is extremely dimensionally stable. It won't expand or contract significantly with temperature swings — which matters enormously in GTA homes that see indoor temperatures range from 15°C in an unheated garage to 28°C in summer. SPC is also 100% waterproof throughout the entire plank, not just the surface.
A solid entry-level SPC option in our inventory: the 315D by Simba Universe 6.5mm Vinyl Flooring at $2.59/sqft. At 6.5mm total thickness with a rigid SPC core, it's built for real life — pets, kids, basement moisture, and the occasional dropped cast iron pan.
What Is WPC Vinyl Flooring?
WPC stands for Wood Plastic Composite. The core blends wood fibre (or foamed PVC) with plastic to create a plank that's noticeably softer and more cushioned than SPC. WPC planks typically run 7–12mm total thickness, and that extra bulk contributes to a warmer, more comfortable feel underfoot — closer to laminate or engineered hardwood than rigid vinyl.
WPC is also 100% waterproof, but its wood-fibre core makes it slightly more vulnerable to prolonged moisture exposure at the edges and seams compared to SPC. More importantly, WPC expands and contracts more with temperature changes — which can cause gapping or buckling in rooms with inconsistent climate control.

Where Each One Actually Performs — Room by Room
Basement: SPC is the clear winner. Concrete slabs in GTA homes — especially anything built before 2005 — release moisture vapor year-round. SPC's inorganic stone core won't absorb that moisture. WPC's wood-fibre content can swell at the edges over time if moisture infiltrates the seams. For any waterproof flooring application below grade, SPC is the safer long-term bet.
Kitchen: Either works, but SPC's harder surface handles dropped items, rolling chairs, and pet claws better. WPC will show dents from chair legs under heavy dining tables faster than SPC.
Living Room / Bedroom (above grade): This is where WPC earns its premium. Standing on WPC for extended periods — cooking, playing with kids — is noticeably more comfortable than SPC. If your main concern is comfort and you have consistent climate control (which most above-grade GTA rooms do), WPC is a legitimate choice.
Stairs: Neither SPC nor WPC should be installed as a floating floor on stairs — they need to be glued or mechanically fastened. SPC's rigidity makes it the preferred choice for stair installations because it won't flex under point-load stress.
The GTA Reality: Why We Sell Mostly SPC
Toronto and the surrounding GTA presents specific flooring challenges that most national content ignores. Here's what actually matters locally:
- Freeze-thaw cycling: GTA homes experience temperature swings of 40°C+ between winter and summer. Rooms with exterior walls, sunrooms, or uninsulated garage-adjacent spaces see dramatic temperature fluctuations. SPC's stone core expands and contracts at roughly 0.02mm per metre per degree Celsius — WPC moves significantly more. In a 400 sqft room, that difference is measurable and can cause gapping at seams.
- Concrete slab moisture: Most GTA homes built between 1960–2000 have basement slabs with no vapour barrier beneath them. Relative humidity in those spaces regularly hits 65–80% in summer. SPC handles this without issue. WPC can handle it too, but the margin for error is smaller.
- Builder-grade flooring aging out: A large portion of GTA homes built in the 1990s–2000s have original engineered hardwood or laminate that's now 20–25 years old. When replacing these floors, the subfloor is often OSB or plywood with minor undulation. SPC tolerates up to 3/16" variation per 10 feet without requiring full levelling — which saves labour costs on professional installation.
- GTA installation pricing: Labour for SPC/WPC floating installation runs $1.50–$2.50/sqft in the GTA. Add $0.50–$1.00/sqft for carpet removal if you're replacing broadloom. Total installed cost for a quality SPC floor like the Simba 315D: roughly $4.50–$5.50/sqft all-in for a typical 1,200–1,500 sqft main floor.

How SPC and WPC Compare to Other Flooring Types
If you're still deciding between vinyl and other materials entirely, here's the honest context:
vs. Laminate: Both SPC and WPC are 100% waterproof. Laminate — even the best waterproof laminate — offers only 72-hour waterproof protection. The Sandy by NAF 12mm Waterproof Laminate at $2.79/sqft is an excellent product for dry or semi-dry spaces, but if your basement ever sees standing water, vinyl wins. See our full laminate flooring category for more options.
vs. Engineered Hardwood: Engineered hardwood looks more premium and adds genuine resale value, but it is not waterproof — not even close. The Sabbia 1/2 Hickory Click System by Northernest at $4.69/sqft is a beautiful above-grade option, but should never go in a basement or any space with moisture risk. Browse our full engineered hardwood collection for above-grade applications where you want real wood character.
vs. Solid Hardwood: Solid hardwood is not suitable for basements, period. It's also more sensitive to humidity fluctuations in kitchens. For those spaces, SPC vinyl is the practical answer every time.

What to Look for When Buying SPC or WPC
Not all SPC is created equal. Here's what the specs actually mean:
- Wear layer thickness: Measured in mils (thousandths of an inch). Residential use: 12 mil minimum. Heavy residential or light commercial: 20 mil+. Budget SPC at 6 mil will scratch visibly within 2–3 years in a busy household.
- Total plank thickness: Thicker is not always better for SPC — a 6mm SPC with a quality core outperforms a 9mm SPC with a foamed-out core. Check the core thickness, not just total thickness.
- AC Rating: AC3 is the residential standard. AC4 is appropriate for home offices or spaces with heavy foot traffic. Most quality SPC in our vinyl flooring inventory is AC3 or AC4.
- Attached underlayment: Most SPC and WPC comes with IXPE or cork underlayment pre-attached. This reduces sound transmission and adds a small amount of thermal insulation. If your product doesn't include it, budget an extra $0.30–$0.60/sqft for a separate underlayment layer.
- Formaldehyde emissions: Look for FloorScore or GREENGUARD Gold certification. This matters especially in basement installations with limited ventilation.
The Bottom Line: Which Should You Choose?
Choose SPC if: you're installing in a basement, kitchen, bathroom, or any space with temperature swings or moisture risk. You want maximum durability and don't mind a firmer feel underfoot. You're replacing flooring in a 1990s–2000s GTA home with an imperfect subfloor.
Choose WPC if: you're installing in an above-grade bedroom or living room with stable climate control. Comfort underfoot is a priority. You're willing to pay a small premium for that softer feel and your space genuinely doesn't face moisture challenges.
When in doubt, SPC is the safer, more versatile choice — which is why it makes up the majority of what we stock and install.

Frequently Asked Questions
Is SPC or WPC better for basements?
SPC is better for basements in virtually every case. Its inorganic stone-limestone core won't absorb moisture vapor from concrete slabs, and it handles the temperature swings common in GTA basements without gapping or buckling. WPC's wood-fibre content makes it more vulnerable to prolonged moisture exposure at the seams over time.
Is WPC vinyl flooring actually waterproof?
Yes — WPC is 100% waterproof at the plank surface and core. However, like all floating floors, water that sits at the seams and edges for extended periods can work its way beneath the floor. Neither SPC nor WPC is a substitute for proper subfloor moisture mitigation in high-risk areas.
How much does SPC vinyl flooring cost installed in Toronto?
Material costs for quality SPC in the GTA range from $2.00–$4.50/sqft. Add $1.50–$2.50/sqft for professional installation labour, plus $0.50–$1.00/sqft for carpet removal if applicable. A typical 1,200 sqft main floor comes in at $5,000–$8,500 fully installed, depending on product selection and subfloor condition.
Can I install SPC vinyl over my existing floor?
In many cases, yes — SPC can float over existing tile, hardwood, or vinyl as long as the existing floor is flat (within 3/16" per 10 feet), firmly bonded, and less than 3/4" total height gain won't create transition problems at doorways. Loose, soft, or heavily damaged existing floors should be removed first.
Does WPC vinyl feel noticeably different than SPC underfoot?
Yes, noticeably so. WPC's thicker, foamed core absorbs impact and feels warmer and softer — similar to walking on a quality laminate. SPC feels firmer and harder, more like ceramic tile. For people who stand for long periods in kitchens or have joint concerns, WPC's cushion is a real practical benefit.
What's the difference between LVP and SPC vinyl?
LVP (Luxury Vinyl Plank) is a broad category that includes both SPC and WPC — it just means a thick, plank-format vinyl floor. When a retailer says "LVP," ask specifically whether the core is SPC or WPC. Most modern LVP sold in Canada today is SPC, but the terminology is often used interchangeably, which causes confusion.
