Best Thickness for Engineered Hardwood Flooring: Toronto Homeowner's Guide
What is the best thickness for engineered hardwood flooring?
For many Toronto houses with suitable plywood subfloors, Parqueteam Hardwood Flooring generally prefers quality 3/4-inch engineered hardwood flooring. However, 1/2-inch and 5/8-inch products can also be excellent choices, especially for condominiums, concrete subfloors and renovations where finished floor height is important.
The most important detail is understanding that overall plank thickness and hardwood wear-layer thickness are not the same thing.
A 3/4-inch engineered hardwood flooring plank with a thin hardwood surface may offer less future refinishing potential than a 5/8-inch plank with a thicker genuine hardwood wear layer.
Plank thickness also does not determine flooring quality on its own.
In this guide, we'll compare common engineered hardwood flooring thicknesses, explain how the wear layer affects long-term value and help Toronto homeowners choose the right product for their property.
Engineered Hardwood Flooring Thickness: Quick Comparison
Overall Thickness | Approximate Metric Equivalent | Common Considerations |
3/8 inch | 9.5 mm | Selected low-profile installations |
1/2 inch | 12.7 mm | Condos, concrete subfloors and renovations |
5/8 inch | 15.9 mm | Versatile residential installations |
3/4 inch | 19.1 mm | Preferred by Parqueteam for many suitable house installations |
These are general product categories rather than universal performance rankings.
Manufacturers may offer slightly different nominal measurements, such as 12 mm, 15 mm, 18 mm or 20 mm.
The installation method, core construction, hardwood wear layer and manufacturer specifications should all be reviewed before purchasing.
1. What Does Engineered Hardwood Flooring Thickness Mean?
Engineered hardwood flooring consists of a genuine hardwood surface bonded to a supporting core.
Two thickness measurements are particularly important.
Overall Plank Thickness
Overall thickness describes the full depth of the engineered hardwood flooring plank, including the natural hardwood surface and supporting layers.
For example, a 3/4-inch engineered hardwood flooring product is approximately 19 mm thick.
Overall thickness can affect:
Compatibility with certain installation methods.
Finished floor height.
Door and transition clearances.
Product construction and stiffness.
Compatibility with existing flooring.
However, a thicker plank is not automatically more stable, more durable or more resistant to scratches.
Hardwood Wear-Layer Thickness
The wear layer is the genuine hardwood surface above the engineered core.
Depending on the product, it may be approximately 1 mm, 2 mm, 3 mm, 4 mm or thicker.
This measurement is particularly important when considering future sanding and refinishing.
A thicker usable hardwood surface generally provides more potential for restoration, assuming the flooring construction and condition permit it.
If you plan to keep your engineered hardwood flooring for many years, ask about both measurements before buying.
2. Is 1/2-Inch Engineered Hardwood Flooring Good?
Yes. Quality 1/2-inch engineered hardwood flooring can be a practical choice for many Toronto properties.
Its relatively low-profile construction may be useful when flooring must meet existing doors, tiles, cabinets or adjacent rooms.
Advantages of 1/2-Inch Engineered Hardwood Flooring
Suitable for certain glue-down installations.
Available in products designed for concrete subfloors.
May reduce finished-floor-height complications.
Can provide genuine hardwood appearance at different price levels.
Available in multiple wood species, colours and finishes.
What Are the Disadvantages?
The main concern is not necessarily the overall thickness but the specific construction.
Some 1/2-inch engineered hardwood flooring products have relatively thin hardwood wear layers, while others have more substantial surfaces.
Installation compatibility can also vary.
A thinner plank should not be assumed suitable for every nail-assisted or floating installation method.
Our Recommendation
Consider quality 1/2-inch engineered hardwood flooring when floor height is limited or the product is appropriately designed for the selected installation system.
Check the hardwood wear layer, core quality and manufacturer specifications rather than judging the product by thickness alone.
3. Is 5/8-Inch Engineered Hardwood Flooring a Good Choice?
For many homeowners, 5/8-inch engineered hardwood flooring offers an attractive middle ground.
It provides a substantial overall construction without reaching the full thickness of a typical 3/4-inch plank.
Quality 5/8-inch products are available with different hardwood wear-layer thicknesses and core designs.
Advantages of 5/8-Inch Engineered Hardwood Flooring
Suitable for a variety of residential renovation projects.
May offer useful finished-floor-height flexibility.
Available in genuine hardwood species such as white oak.
Can be appropriate for approved glue-down and other installation systems.
Certain products provide meaningful refinishing potential.
Does 5/8-Inch Engineered Hardwood Flooring Last Longer Than 1/2-Inch Flooring?
Not automatically.
Two products of different thicknesses can have different surface finishes, wear layers and manufacturing quality.
A well-constructed 1/2-inch product may outperform a poorly manufactured 5/8-inch product.
For long-term durability, evaluate the flooring as a complete system.
Our Recommendation
Quality 5/8-inch engineered hardwood flooring is worth considering for Toronto homeowners who want a balance between finished-floor height, construction and product selection.
4. Is 3/4-Inch Engineered Hardwood Flooring the Best Option?
At Parqueteam Hardwood Flooring, 3/4-inch engineered hardwood flooring is generally our preferred starting point for suitable residential installations.
This is especially true for many houses with properly prepared plywood subfloors where a quality nail-and-glue-assisted installation is planned.
However, 3/4-inch engineered hardwood flooring is not automatically the best option for every property.
Advantages of 3/4-Inch Engineered Hardwood Flooring
Quality products may offer:
Substantial engineered plank construction.
Compatibility with certain nail-and-glue-assisted installation systems.
A range of wide-plank hardwood flooring options.
Genuine hardwood surfaces in multiple finishes.
Potential for substantial hardwood wear layers.
Important Limitations
A thicker engineered hardwood flooring plank can create additional height at transitions, doors and stair connections.
Premium products may also cost more.
Most importantly, the overall 3/4-inch thickness does not guarantee a thick hardwood wear layer.
A manufacturer can produce a thick engineered plank with a relatively thin genuine hardwood surface.
Our Recommendation
For a Toronto house with a suitable plywood subfloor and sufficient height clearance, a well-manufactured 3/4-inch engineered hardwood flooring product is often an excellent choice.
But if a quality 5/8-inch product offers a better wear layer or suits the installation conditions more closely, it may provide better overall value.
5. What Is the Best Hardwood Wear-Layer Thickness?
This is one of the most important questions homeowners should ask.
The hardwood wear layer influences the potential for future refinishing, although it does not independently determine how long the factory finish will last.
Hardwood Wear Layer | What Homeowners Should Know |
Around 1 mm | Generally unsuitable for conventional sanding |
Around 2 mm | Limited refinishing potential; do not assume a full sanding is possible |
2.5–3 mm | Certain products may qualify for refinishing, subject to construction and condition |
Around 4 mm | Greater potential for future restoration |
5–6 mm | Substantial hardwood surface, with potential for additional refinishing |
These are general guidelines, not guaranteed numbers of refinishing cycles.
What Does the National Wood Flooring Association Recommend?
The National Wood Flooring Association (NWFA) established a Refinishable Program that includes minimum wear-layer criteria for eligible wood flooring.
Among its requirements:
Factory-finished smooth wood flooring: at least 2.5 mm.
Unfinished smooth wood flooring: at least 3.2 mm.
Sculpted or distressed wood flooring: at least 2.5 mm at the lowest point.
These minimums help establish whether certain products qualify for the program. They do not guarantee a specific number of future sanding cycles.
Actual refinishing suitability depends on the remaining usable wood, the flooring's condition and the installation.
Is a 4 mm Hardwood Wear Layer Worth It?
For homeowners prioritizing long-term restoration options, a quality engineered hardwood flooring product with approximately 4 mm of usable hardwood can be worth considering.
However, the price difference should be evaluated alongside core construction, finish quality and product specifications.
A thicker wear layer is valuable, but it should not be the only purchasing criterion.
6. Which Engineered Hardwood Flooring Thickness Is Best for Toronto Condos?
For many Toronto condos, both 1/2-inch and 5/8-inch engineered hardwood flooring can be practical options.
A quality 3/4-inch product may also be suitable when the building and project conditions permit it.
The choice depends on more than the plank's thickness.
Many condominiums have concrete subfloors, existing floor-height restrictions and sound-control requirements.
Important Condo Considerations
Acoustic approval: The building may require a tested flooring assembly with approved underlayment.
Concrete conditions: Moisture and surface flatness must satisfy the flooring manufacturer's requirements.
Installation method: Floating, glue-down and double glue-down systems have different requirements.
Floor height: Acoustic membranes and adhesives add to the finished height of the flooring assembly.
A thicker engineered hardwood flooring product does not automatically provide better sound insulation.
Condo owners should confirm the approved flooring system with building management before purchasing materials.
7. Which Thickness Is Best for Houses With Plywood Subfloors?
For houses with suitable plywood subfloors, 3/4-inch engineered hardwood flooring is often our preferred option.
Depending on the selected product, nail-and-glue-assisted installation may be appropriate.
However, thinner engineered hardwood flooring can also perform successfully when the manufacturer approves the installation method.
Why Subfloor Preparation Still Matters
Even a thick engineered hardwood flooring product can develop problems over an unsuitable substrate.
Before installation, the subfloor should be evaluated for:
Loose or damaged plywood.
Excessive unevenness.
Moisture conditions.
Structural movement.
Compatibility with the proposed fastening or adhesive system.
A thicker flooring plank cannot compensate for a poorly prepared subfloor.
8. What Thickness Is Best for Concrete and Basements?
Engineered hardwood flooring can be installed over suitable concrete when the selected product is approved for the application.
Glue-down and floating engineered hardwood flooring systems are commonly considered for properly prepared concrete subfloors.
However, thickness alone does not determine whether the flooring is suitable.
Concrete Subfloor Considerations
Concrete moisture must be evaluated according to the product and adhesive manufacturers' requirements.
The floor must also meet the applicable flatness and surface-preparation specifications.
For Toronto basement floors, it is especially important to investigate existing moisture or water infiltration problems.
Engineered hardwood flooring is not waterproof.
A thicker plank will not protect the flooring against ongoing basement moisture problems.
Our Recommendation
Choose a manufacturer-approved engineered hardwood flooring product and installation system that suits the concrete conditions.
When ceiling height or door clearance is limited, a suitable 1/2-inch product may be worth considering.
9. Does Thicker Engineered Hardwood Flooring Cost More?
In many product collections, thicker engineered hardwood flooring costs more because it may require additional materials or more substantial construction.
However, thickness is only one pricing factor.
Wood species, hardwood wear layer, finish, plank dimensions and manufacturer can have an equally important influence.
At Parqueteam Hardwood Flooring, engineered hardwood flooring materials generally cost $4.99–$11.99 per square foot.
Installation labour depends on the selected system.
Installation Method | Typical Labour Rate |
Click-lock floating engineered hardwood flooring | $1.50–$2.50/sq. ft. |
Nail-and-glue-assisted engineered hardwood flooring | $2.50–$3.50/sq. ft. |
Full glue-down engineered hardwood flooring | $3.00–$4.50/sq. ft. |
Herringbone engineered hardwood flooring | $5.50–$7.50/sq. ft. |
Adhesives, acoustic membranes, subfloor preparation, removal, material waste and taxes are additional unless included in the quotation.
When comparing flooring samples, determine whether a higher-priced product offers a better hardwood wear layer, construction or finish—not simply more overall thickness.
10. How to Choose the Right Engineered Hardwood Flooring Thickness
Before making a purchase, consider the following factors.
Installation method: Confirm that the product is approved for floating, nail-assisted or glue-down installation, as appropriate.
Subfloor material: Concrete and plywood can require different systems.
Floor height: Account for door clearances, existing tile, thresholds and stair transitions.
Hardwood wear layer: Consider future refinishing potential if you expect to keep the flooring long-term.
Product quality: Examine core construction, manufacturing quality and the warranty.
Indoor conditions: Maintain temperature and relative humidity within the manufacturer's requirements.
Overall budget: Compare the complete installed price rather than the cost of the planks alone.
For many homeowners, a quality engineered hardwood flooring product with a suitable hardwood wear layer is a better investment than simply purchasing the thickest available board.
Frequently Asked Questions About Engineered Hardwood Flooring Thickness
What is the best thickness for engineered hardwood flooring?
For many Toronto houses with suitable plywood subfloors, Parqueteam generally prefers quality 3/4-inch engineered hardwood flooring. For condos and projects with limited floor height, 1/2-inch or 5/8-inch products may be more practical.
Is 1/2-inch engineered hardwood flooring thick enough?
Yes. Quality 1/2-inch engineered hardwood flooring can perform well when it is approved for the installation method and installed over a suitable subfloor.
Is 5/8-inch engineered hardwood flooring better than 1/2-inch?
Not automatically. The core construction, hardwood wear layer, finish quality and installation suitability are more important than the overall thickness difference alone.
Is 3/4-inch engineered hardwood flooring worth the extra money?
It can be worthwhile for suitable house installations, but it is not automatically superior. Compare the actual product specifications and finished-floor-height requirements.
Is a 2 mm hardwood wear layer enough for refinishing?
Do not assume so. A 2 mm hardwood wear layer generally offers limited sanding potential. The NWFA's Refinishable Program specifies higher minimums for eligible flooring products.
What is the best hardwood wear-layer thickness?
For homeowners who want meaningful future refinishing potential, approximately 3–4 mm or more is worth considering, subject to the manufacturer's specifications and the flooring's eventual condition.
Does thicker engineered hardwood flooring soundproof a condo better?
Not necessarily. Sound transmission depends on the complete flooring assembly, including acoustic underlayment and building construction. Approval should be based on the condominium's requirements.
Can 3/4-inch engineered hardwood flooring be installed over concrete?
Yes, certain 3/4-inch products are suitable for approved concrete installations. The manufacturer must permit the selected installation method, and the substrate must meet moisture and preparation requirements.
Final Verdict: What Thickness Should You Choose?
For many Toronto house installations, quality 3/4-inch engineered hardwood flooring remains our preferred starting point.
For condos, concrete subfloors and renovations with height restrictions, 1/2-inch and 5/8-inch engineered hardwood flooring can be equally practical choices.
However, total thickness should never be considered independently of the hardwood wear layer, core construction, subfloor and installation system.
If long-term restoration is important, pay particular attention to the thickness of the genuine hardwood surface.
The best product is not necessarily the thickest engineered hardwood flooring available. It is the product whose complete specifications best match your home.
