When choosing SPC vinyl flooring, thickness matters—but not always in the way most people expect. The right choice depends on your room, your subfloor, and whether you need sound dampening or moisture protection. This SPC flooring thickness guide breaks down exactly what each option delivers for Toronto homes.
What SPC Thickness Actually Means for Your Floor
SPC (Stone Plastic Composite) flooring thickness ranges from 6mm to 10mm, but the core layer provides structural stability rather than cushioning. Unlike carpet or some laminate products, more thickness in SPC doesn't mean a softer feel—it means better resistance to subfloor imperfections, improved acoustics, and a more solid sensation underfoot.
The wear layer—the protective top coating—typically ranges from 0.3mm to 0.7mm and determines scratch and scuff resistance. This is separate from total plank thickness. A 6mm plank with a 0.5mm wear layer can actually outperform an 8mm plank with a 0.3mm wear layer in durability, even though it's thinner overall.
Top Floorings Depot stocks vinyl plank flooring in Toronto across multiple thicknesses for residential and commercial projects across the GTA. Product specifications vary, so confirm exact details on each product page.
Basement Installations: Moisture and Subfloor Considerations
Toronto basements often have uneven concrete subfloors with minor height variations. Thicker SPC (8mm–10mm) bridges these minor subfloor imperfections better without telegraphing flaws through the planks. This can save you from extensive subfloor preparation before installation.
All SPC vinyl provides excellent water resistance for basement moisture concerns, which is a major advantage in below-grade spaces. However, proper installation preparation remains essential—even waterproof flooring needs correct acclimation and seam sealing to perform as intended.
Thicker options at Top Floorings Depot offer improved sound absorption for basement entertainment areas or rental suites. If you're finishing a basement in a North York semi or a Scarborough townhome, this can make a meaningful difference in how the space feels day-to-day.

Condo and Apartment Flooring: Sound Dampening Requirements
Toronto condo boards often require minimum Impact Insulation Class (IIC) ratings for flooring installations. This is where thickness and underlayment become critical considerations. SPC with a total thickness of 8mm or more, combined with attached underlayment, helps meet these standards.
Thicker SPC reduces footfall noise and provides a more solid feel underfoot for upper-floor condo units. This matters especially in high-rise buildings where sound transmission between units is a common concern. The Riche Flooring Heavy-Duty 8mm SPC Vinyl series, for example, includes a 2mm EVA pad pre-attached, achieving IIC 73 and STC 72 ratings that satisfy most Toronto condominium requirements.
Top Floorings Depot recommends checking your building's flooring requirements before selecting thickness. Many condos have specific guidelines around wear layer minimums, total floor height, and approved underlayment. The Condo Soundproof Flooring Guide covers these requirements in more detail.
Living Areas and High-Traffic Residential Zones
For main-floor living rooms, bedrooms, and hallways where subfloor conditions are generally good, 6mm–8mm SPC works well. These spaces typically have cleaner, more level subfloors, so the extra thickness doesn't provide significant advantage.
The 10mm SPC option offers the most comfortable underfoot experience and best sound performance for family rooms and hallways where you want that premium feel. It also handles heavy furniture better without potential flexing at seams.
All three thicknesses provide comparable durability when wear layer specifications match your household traffic levels. A 6mm plank with a 20mil wear layer handles pet claws and daily family traffic similarly to a 10mm plank with the same wear layer—the difference is feel and acoustic performance, not longevity.

Quick Comparison: Choosing Your SPC Thickness
| Thickness | Best For | Key Advantage |
|---|---|---|
| 6mm | Budget-conscious projects, level subfloors, rentals, quick renovations | Cost-effective when conditions allow |
| 8mm | Most residential rooms, condos, finished basements, upper floors | Balanced performance, meets most condo requirements |
| 10mm | Main living areas, family rooms, spaces where comfort matters most | Premium feel, best acoustics |
6mm SPC works as a budget-conscious choice for projects where subfloors are already level and sound dampening isn't a priority. It's practical for rental property updates or quick renos where you need good looks without premium investment.
8mm SPC is the balanced option providing solid performance across most residential applications. With attached underlayment, it satisfies condo board requirements while still handling family traffic, pets, and everyday wear. Top Floorings Depot carries 8mm Waterproof SPC Vinyl Plank Flooring in multiple colours and finishes.
10mm SPC delivers premium comfort and sound dampening for spaces where feel matters most. The extra thickness makes a noticeable difference in family rooms, master bedrooms, or any upper-floor space where you want to minimize footfall noise.

Making Your Final Decision
Choosing between 6mm, 8mm, and 10mm SPC comes down to three practical questions:
-
What's your subfloor like? Older basements with uneven concrete benefit from 8mm or 10mm. Newer main floors with level subfloors work fine with 6mm.
-
Do you have condo requirements? Check your building's IIC requirements. Most need at least 8mm with proper underlayment to pass.
-
How important is underfoot feel? If comfort and sound matter—family rooms, upstairs bedrooms—invest in 10mm or at minimum 8mm with quality attached underlayment.

Frequently Asked Questions
Does thicker SPC flooring mean better quality? Not necessarily. Thickness affects sound dampening and subfloor forgiveness, but wear layer quality and core density determine overall durability. A quality 8mm plank often outperforms a budget 10mm plank.
Is 6mm SPC too thin for everyday residential use? 6mm works well for residential use when subfloors are level and sound dampening isn't a priority. It's a practical choice for bedrooms, rentals, and projects with tight budgets. The key is pairing appropriate thickness with a sufficient wear layer for your traffic levels.
What's the difference between SPC and LVP thickness? SPC (Stone Plastic Composite) and LVP (Luxury Vinyl Plank) are similar products, but SPC has a rigid stone-polymer core that provides more dimensional stability. SPC typically performs better over imperfect subfloors and handles temperature changes more reliably—a relevant consideration for Toronto's freeze-thaw cycles.
Do I need underlayment with SPC vinyl flooring? Many SPC products come with attached underlayment, eliminating the need for separate underlayment. If your SPC doesn't include attached underlayment, a proper underlayment is recommended—especially for sound dampening in condos or multi-level homes.
Will thicker SPC help with a slightly uneven basement subfloor? Yes. Thicker SPC (8mm–10mm) bridges minor subfloor imperfections better than thinner options. However, significant height variations still need subfloor preparation. For details on basement subfloor requirements, see the Basement Flooring Guide.
How do I know if my condo board requires specific flooring thickness? Contact your building management or strata corporation directly. They'll provide their flooring guidelines, including minimum IIC ratings, wear layer requirements, and approved installation methods. Top Floorings Depot can help you find products that meet common Toronto condo standards.
Can I install SPC flooring over existing vinyl or laminate? In many cases, yes—but the existing floor must be level, firmly adhered, and in good condition. Remove any damaged sections and ensure no moisture issues before proceeding. Check product installation guidelines for specific requirements.
What's a good wear layer for households with pets? For pet owners, a 20mil (0.5mm) wear layer provides excellent scratch and scuff resistance. This is the heavy-duty commercial-grade specification found in the Riche Flooring Heavy-Duty series and handles pet claws well without showing wear prematurely.
How does SPC flooring handle Toronto winters? SPC flooring handles temperature fluctuations well due to its rigid stone-polymer core. Unlike hardwood, it won't warp or buckle with humidity changes common in heated Toronto winters. This stability makes it suitable for spaces with baseboard heating systems.
Should I acclimate SPC flooring before installation? Yes. Even waterproof SPC flooring benefits from acclimation—typically 24–48 hours in the installation space at room temperature. This allows the planks to adjust to ambient conditions and ensures proper fit after installation. Confirm specific acclimation requirements with your product documentation.
