The best luxury vinyl plank for most homes is a rigid-core click-lock plank with a 20 mil wear layer and an attached pad — COREtec Plus Enhanced if you want it warmer and quieter underfoot, Shaw Floorte Pro or Pergo Extreme if you want a denser, more dent-resistant SPC core. Below 12 mil is for bedrooms and closets; 20 mil is the sensible floor for kitchens, hallways and pets; 22 mil and above earns its premium only in genuinely hard-wearing spaces.
Everything else on the box — "waterproof", "pet-proof", the total thickness in millimetres — matters far less than those two specs and the condition of the subfloor underneath. A premium plank on an uneven floor will click, gap and break its locks; a mid-priced plank on a flat, dry subfloor will outlast it.

Product Specs
- Type: Wpc Rigid Core / Cork-Backed
- Rank in this guide: #1
COREtec is the brand that popularised rigid-core vinyl, and the Plus Enhanced planks are the range most homeowners should start with. The published construction is an 8 mm plank with a 20 mil wear layer, a waterproof WPC core and an attached cork underlayment. That combination hits the three things people actually notice in daily life: it shrugs off kitchen and hallway traffic, it feels and sounds less hollow than thinner SPC planks, and the cork backing takes some of the chill out of the floor.
The foamed WPC core is the trade-off. It is softer than an SPC core, so a heavy point load — a piano leg, a loaded bookcase on narrow feet, a dropped cast-iron pan — can leave a permanent dent that an SPC plank would resist. Use wide furniture cups and it is a non-issue for most rooms. It also costs more than big-box SPC, and you are paying partly for the comfort.
What We Like
- Rigid core resists dents from toys, chairs and pet traffic
- Waterproof core handles spills and accidents
- Attached pad simplifies DIY installation
- Multiple collections and price points
What We Don’t Like
- Specs vary by collection — easy to buy the lighter-duty one
- Harder and louder underfoot than cork-backed WPC
- Surface still scratches under large-dog claws
Product Specs
- Type: Rigid Core Lvp / Attached Pad
- Rank in this guide: #2
Pergo Extreme is the vinyl side of a brand better known for laminate, built on a rigid waterproof core with an attached underlayment and sold in several collections at different price points. For a house with dogs and children, a rigid core is the right starting point: it resists dents from dropped toys and chair legs far better than WPC, and the waterproof core means a water bowl knocked over at 2 a.m. or an accident on the floor is a wipe-up rather than a swollen plank.
The collections are not identical, which is the important caveat. Wear layer and thickness vary across the range, so pick a collection with a 20 mil wear layer for pet households — claws drag grit across the surface, and that is exactly the abrasion the wear layer exists to absorb. No vinyl is scratch-proof under a large dog's nails; a 20 mil layer simply means the print film survives the scratching for many more years.
What We Like
- Dense SPC core is dimensionally stable through seasonal swings
- Good dent resistance for gym equipment and heavy furniture
- Waterproof core suits below-grade use
- Wide choice of collections and plank formats
What We Don’t Like
- Feels harder and cooler underfoot than WPC
- Collection-by-collection specs need checking
- Underlayment and vapour-barrier rules vary between collections
Product Specs
- Type: Spc Rigid Core
- Rank in this guide: #3
Shaw's Floorte Pro family is built on stone-plastic composite cores, and SPC is the core type that belongs on a basement slab. A dense, limestone-filled core moves less with temperature and humidity than foamed WPC, so it is less likely to gap in a cool winter basement or peak when the dehumidifier is off for a week in August. It also takes the weight of a sectional, a treadmill or a home gym with less risk of permanent indentation.
Floorte Pro spans several collections with different wear layers and plank sizes; the ones carrying "Plus" in the name generally add an attached underlayment. On concrete, check whether Shaw requires a separate 6-mil polyethylene vapour retarder for your chosen collection — the answer determines what goes under the plank, and getting it wrong is the commonest way to void a basement warranty.
What We Like
- 22 mil options at a mid-market price
- Attached pad — no separate underlayment to buy
- Widely stocked, easy to buy extra boxes and trims
- Large colour range
What We Don’t Like
- Entry products are thinner with only 12 mil wear layers
- Sold through one retailer
- SPC is firmer and louder than cork-backed WPC
Product Specs
- Type: Spc Rigid Core / Attached Pad
- Rank in this guide: #4
LifeProof is Home Depot's house brand, and its value lies in availability as much as price: dozens of colours, most in stock, with matching transitions and stair nosing on the same shelf. The rigid-core planks come with an attached pad, and wear layers vary widely across the range, topping out at 22 mil on the better collections — read the spec on the box rather than assuming.
That spread is the thing to watch. The cheapest LifeProof products are thinner with a lighter wear layer — perfectly good for bedrooms and a home office, under-specified for a kitchen with a dog. The 22 mil versions cost more but are still competitive with premium-brand 20 mil planks, which makes them the best value pick in this list for high-traffic rooms on a budget. Buy every box for a room from the same dye lot and open several at once while laying, so colour variation is blended across the floor.
What We Like
- Commercial-rated wear layer
- No expansion transitions over long runs
- Cabinets and islands can sit on top
- Handles rolling loads and office chairs
- Individual planks replaceable
What We Don’t Like
- Demands a very smooth, flat subfloor
- Professional installation recommended
- No pad — harder and colder underfoot
- Sold through flooring retailers rather than big boxes
Product Specs
- Type: Flexible Glue-Down Lvt
- Rank in this guide: #5
Van Gogh is Karndean's flagship glue-down plank: a thin, flexible "dryback" vinyl bonded to the subfloor with adhesive and carrying a commercial-rated wear layer. Glue-down is the right construction when a floating floor is the wrong one — long open-plan runs that would otherwise need expansion transitions, kitchens where heavy islands and cabinets would pin a floating floor, rooms with office chairs and rolling loads, retail and rental properties that need individual planks replaced without unclicking a wall's worth of floor.
The price of that performance is preparation and labour. A thin glued plank telegraphs every trowel ridge, nail head and dip in the subfloor straight through to the surface, so the floor needs skim-coating or self-levelling to a high standard first. It is a professional install for most homeowners, and it is colder and harder underfoot than a padded click plank.
What We Like
- Convincing textured wood visuals
- 20 mil wear layer suits high-traffic rooms
- Waterproof rigid core with attached underlayment
- Broad range of plank sizes
What We Don’t Like
- Premium pricing
- Mostly sold through independent flooring dealers
- Rigid core is firmer underfoot than cork-backed WPC
Product Specs
- Type: Rigid Core Lvp / Wood Visuals
- Rank in this guide: #6
Mannington has made resilient flooring for generations, and Adura Max is its rigid-core, waterproof click line with an attached underlayment; check the wear layer on the specific collection, as it varies. Where it stands out is the visuals: a wide range of plank widths and lengths, painted bevels and texture registered to the grain on many styles, so the surface feel follows the knots and rays rather than being a uniform pattern pressed over the whole plank.
The things that make LVP look like vinyl are short planks, repeating prints and a flat, slightly plasticky sheen. Longer planks and a large number of unique print screens reduce all three. Whatever line you choose, lay planks out from several boxes before installing and pull any obviously repeating boards — that does more for realism than the brand alone.
Two other widely sold lines deserve a mention. Mohawk SolidTech is Mohawk's waterproof rigid-core family, and Smartcore is Lowe's in-store brand, which plays the same role there that LifeProof plays at Home Depot. Both are judged exactly the same way: check the wear layer for the room, the core type for the space, and whether the pad is attached.
SPC vs WPC vs Glue-Down
"Luxury vinyl plank" now covers three quite different constructions. They share a printed design film and a clear wear layer on top; the difference is what sits underneath.
| Construction | Core | Typical thickness | Strengths | Weaknesses |
|---|---|---|---|---|
| SPC (stone-plastic composite) | PVC + limestone, dense | 4 – 8 mm | Dent resistance, dimensional stability, basements | Hard, cold, louder footfall |
| WPC (wood/wood-plastic composite) | Foamed PVC, lighter | 6 – 9 mm | Warmer, quieter, softer underfoot | Dents under point loads, moves more with heat |
| Flexible / glue-down (dryback) | Thin flexible vinyl | 2 – 3 mm | Long runs, rolling loads, cabinets on top | Needs a near-perfect subfloor, pro install |
SPC is the default today because it is dense, stable and cost-efficient. Limestone filler makes the core stiff and heavy, which is why SPC planks shrug off chair legs and furniture and why they move very little when the room heats and cools. That stability is the reason to prefer it in basements, sunrooms with good blinds, and anywhere the thermostat gets turned down for weeks. The cost is comfort: SPC is hard underfoot and transmits footfall noise, which is why an attached pad matters more on SPC than on anything else.
WPC uses a foamed core — the "wood" in the name is largely historic, and most modern WPC cores are foamed PVC. The air in the foam makes it lighter, warmer to the touch and quieter, and it feels closer to engineered wood when you walk on it. The same softness lets a narrow heavy load leave a dent, and the core expands and contracts more with temperature. Upstairs living rooms and bedrooms are its natural territory.
Flexible glue-down plank is the original LVT and still what most commercial spaces use. It is thin, fully bonded and does not float, so it never needs the expansion breaks a floating floor requires and it tolerates rolling loads. It is unforgiving of the subfloor — and if you are refinishing an existing wooden floor instead, our guide to the best water-based polyurethane for floors covers that route.
Wear Layer: What the Mils Mean
The wear layer is the transparent film over the printed design, measured in mils — thousandths of an inch, not millimetres. It is the single best predictor of how long the floor will keep looking new, because once grit and traffic abrade through it, the print wears and the damage cannot be repaired except by replacing planks.
| Wear layer | In millimetres | Suits | Avoid in |
|---|---|---|---|
| 6 – 8 mil | ≈ 0.15 – 0.2 mm | Closets, guest rooms, short-term rentals on a budget | Anywhere with daily traffic |
| 12 mil | ≈ 0.3 mm | Bedrooms, home offices, low-traffic living rooms | Kitchens, entries, large dogs |
| 20 mil | ≈ 0.5 mm | Kitchens, hallways, family rooms, pets, basements | Little — the sensible default |
| 22 – 28+ mil | ≈ 0.55 – 0.7+ mm | Mudrooms, entries off a garage, light commercial, rentals | Bedrooms — you are paying for durability you won't use |
Two clarifications matter. First, the wear layer governs abrasion, not dents. A 22 mil plank on a soft WPC core still dents under a fridge foot; a 12 mil plank on dense SPC resists it. Dent resistance comes from the core. Second, the fine scratches that make a floor look tired mostly happen in the factory-applied urethane or ceramic-bead coating on top of the wear layer. Every brand has a version of this coating, and it is why gritty entries benefit from a good walk-off mat more than from any extra mil.
Kitchens need 20 mil: chair legs, dropped utensils and grit carried from the back door. Pets need 20 mil plus trimmed nails, and owners of large, active dogs should consider 22 mil and a lighter, mid-tone colour that disguises surface scuffing better than very dark or very light planks. Basements earn 20 mil if they are a family room or gym, and 12 mil is acceptable for a storage room or guest suite.
Total Thickness and Attached Pads
Total thickness — usually quoted as 5 mm, 6.5 mm, 8 mm and so on — is mostly core and pad. It is not a durability number, and a 9 mm plank with a 12 mil wear layer will wear out sooner than a 6 mm plank with 20 mil. What thickness does buy is a stiffer plank that bridges small subfloor dips, a more solid feel, and better sound behaviour. Above about 8 mm the returns diminish quickly.
Most rigid-core planks now come with an attached pad, typically 1–1.5 mm of IXPE foam or cork. It improves comfort and dampens the hollow sound floating floors are known for. The firm rule: do not add a second underlayment under a padded plank. A soft layer below lets the click joints flex every time someone steps on them, and that flex is what breaks the locking edges and opens gaps. Most manufacturers void the warranty if you do it.
An attached pad is not automatically a vapour barrier. Some manufacturers accept their attached pad as sufficient on concrete; others still require a 6-mil polyethylene sheet underneath. That is a manufacturer-specific instruction, and on a basement slab it is the one to look up before buying.
Waterproof vs Water-Resistant
"Waterproof" on an LVP box means the plank itself does not swell when wet. SPC and WPC cores contain no wood fibre to absorb water, so a spill left overnight, a leaking dishwasher or a wet dog will not damage the plank. That is a genuine advantage over laminate, which is usually marketed as water-resistant: the surface sheds water for a period, but water that reaches the fibreboard core at the edges causes swelling.
What "waterproof" does not mean is that the floor protects the house. A floating floor has joints; standing water seeps through them and around the perimeter to the subfloor below, and a plank floor sitting over a wet subfloor can trap moisture and grow mould. After a real leak, floating LVP is often unclicked, dried out and reinstalled — a nice advantage — but the subfloor needs to dry first. For bathrooms, seal the expansion gap around tubs and toilets with 100% silicone, and treat the planks as protecting themselves, not your joists.
Installation: Subfloor, Acclimation, Gaps
Click-lock floating installation is why LVP has become the most popular DIY floor. Planks lock together on their long and short edges and the whole floor floats over the subfloor, held down by its own weight and the trim around the edge. A reasonably handy homeowner can do a bedroom in a day with a tape, a utility knife, a tapping block and a pull bar.
Subfloor Flatness
The tolerance most rigid-core manufacturers publish is in the region of 3/16 inch over 10 feet (some also specify 1/8 inch over 6 feet). Lay a long straightedge across the floor in several directions and slide shims under the gaps. Dips get filled with patching compound or self-leveller; humps on concrete get ground and on wood get planed or sanded. A floor that is out of tolerance produces the most common LVP complaints: planks that click when walked on, joints that peak or open, and broken locking tongues. Glue-down planks need it flatter and smoother still.
Acclimation
Requirements vary. Many SPC lines say little or no acclimation is needed; WPC and glue-down products more often specify 24–48 hours in the room, boxes laid flat, at normal living temperature. The safe default is to bring the boxes into the room two days ahead with heating or cooling running as normal. Planks installed cold from a garage in winter expand when the house warms them, which is exactly the movement the expansion gap is supposed to absorb rather than add to.
Expansion Gaps and Transitions
Leave about 1/4 inch at every wall, pipe, door jamb and fixed object — more if the manufacturer says so. Baseboard or quarter round covers it. Undercut door casings so the plank slides beneath rather than being butted against them. Most floating floors also need a T-moulding transition at doorways and once a run exceeds the manufacturer's maximum, which on many lines is in the range of 40–50 feet in one direction.
Never pin a floating floor. Kitchen islands, built-in cabinets and heavy fixed shelving should sit on the subfloor with the plank cut around them, not on top of it. A floor that cannot move will buckle somewhere else, usually in the middle of a room in the first summer.
Basements and Concrete Slabs
LVP is the best mainstream finished floor for basements, because it is the only common option that does not mind occasional damp. But a waterproof plank on a wet slab is still a problem floor: moisture moving up through the concrete condenses under the floor, the subfloor stays damp, and mould and musty smells follow even when the planks look perfect.
Fix water first. Seepage through walls, wet corners after rain or efflorescence on block need dealing with before the floor goes in; our guide on how to waterproof basement walls covers the sequence, and a masonry sealer for basement walls is part of it on block foundations.
Then test the slab. The quick check is to tape a two-foot square of plastic sheet down on all four edges and leave it for 24–48 hours. Damp underneath means vapour is coming through. For a definitive number, manufacturers quote limits from in-slab relative humidity probes (ASTM F2170) or calcium chloride tests (ASTM F1869). Many floating LVP lines accept slabs up to roughly 85% RH, but the figure varies — check before relying on it.
Use the right barrier. On concrete, a 6-mil polyethylene sheet, seams overlapped and taped and turned up the wall behind the trim, is the usual requirement unless the manufacturer accepts its attached pad instead. Do not substitute a foam underlayment for a barrier on top of a padded plank.
Control humidity. A basement held at 45–55% relative humidity is better for the floor, the drywall and everything stored down there. A dedicated basement dehumidifier is the cheapest insurance in the whole finished-basement budget. Choose SPC over WPC for its dimensional stability. If the space is really a workshop or garage-style utility room, a coating is the better finish — compare options in our garage floor coating guide, or for a low-cost painted finish see the best concrete floor paint.
AC Ratings, Use Classes and VOCs
AC ratings are a laminate standard, not a vinyl one. AC1 to AC5 come from the abrasion and impact tests in EN 13329, the European laminate specification. You will occasionally see an AC rating on a vinyl listing, but it is borrowed terminology; for LVP the meaningful durability numbers are the wear layer in mils and the use class.
Use classes come from the European resilient flooring classification (EN ISO 10874): a 2 prefix is domestic and a 3 prefix is commercial, with the second digit indicating traffic intensity. Class 23 means heavy domestic use; class 33 means heavy commercial; class 32 or 33 on a residential plank suggests a robust wear layer. In North America, warranties are a practical proxy: a "lifetime residential, 10–15 years light commercial" warranty usually signals a 20 mil-class product.
Indoor air quality is the other thing to check. Look for FloorScore certification, administered by SCS Global Services, which shows the product meets the California Department of Public Health emission limits for VOCs. Major brands have moved to phthalate-free plasticisers in the last decade, and most now say so on the spec sheet. Expect a mild smell from newly unboxed planks; ventilate for a few days after installation, especially with glue-down adhesives.
Cost per Square Foot
| Category | Materials / sq ft | Installed / sq ft | Notes |
|---|---|---|---|
| Entry SPC, 6 – 12 mil | $1.50 – $3.00 | $3.50 – $6.00 | Bedrooms, rentals, light use |
| Mid-range rigid core, 20 – 22 mil, pad | $3.00 – $5.00 | $5.00 – $9.00 | The value sweet spot |
| Premium WPC / SPC, designer visuals | $4.50 – $7.00 | $7.00 – $11.00 | Cork backing, long planks, premium texture |
| Commercial glue-down | $3.50 – $7.00 | $7.00 – $12.00+ | Includes adhesive; prep often extra |
Installation labour for click-lock LVP typically runs $1.50–$4 per square foot, more for stairs, which are usually charged per step. The extras that do not appear in the headline price are removing the old floor ($1–$2 per square foot for carpet or tile removal), self-levelling or patching ($1–$3 per square foot where the floor is out of tolerance), new baseboard or quarter round, transitions, stair nosing, and moving furniture and appliances.
Order 10% extra for waste on a straight lay, more on rooms with many angles or a diagonal pattern, and keep a box after the job for repairs — dye lots change and a matching plank three years later is not guaranteed.
DIY saves the labour line, which on a 500 sq ft main floor is roughly $750–$2,000. The work itself is not hard; subfloor flattening is where DIY jobs go wrong, so measure the floor with a straightedge before deciding whether to tackle it yourself.
The Short Version
Pick the core for the space: SPC for basements, sunrooms and heavy furniture; WPC for upstairs comfort; glue-down for large open plans, commercial use and kitchens with heavy islands.
Pick the wear layer for the traffic: 12 mil for bedrooms, 20 mil for kitchens, hallways, basements and anything with paws, 22 mil and above for entries and rentals.
Then spend the effort where floors actually fail: a subfloor flat to 3/16 inch in 10 feet, the right vapour barrier on concrete, a 1/4 inch gap at every wall, and nothing heavy pinning the floor. COREtec Plus Enhanced is the best all-rounder, LifeProof's 22 mil planks are the best value, and Shaw Floorte Pro is the pick for a basement slab.
Frequently Asked Questions
Match it to the traffic. A 12 mil wear layer is fine for bedrooms, home offices and other low-traffic rooms. A 20 mil wear layer is the sensible default for kitchens, hallways, family rooms, basements and any home with dogs, and it typically carries a light-commercial warranty as well as a residential one. 22 mil and above is worth paying for in mudrooms, entries from a garage, rentals and light commercial spaces. Below 12 mil — the 6 and 8 mil products — belongs only in closets and spare rooms. Remember that the wear layer governs abrasion; dent resistance comes from the core.
Neither across the board. SPC has a dense limestone-filled core that resists dents and stays dimensionally stable through temperature changes, which makes it the better choice for basements, sunny rooms, heavy furniture and home gyms. WPC has a foamed core that is warmer, quieter and softer underfoot, which suits upstairs living rooms and bedrooms where comfort matters. The trade-off is that WPC dents more readily under heavy point loads and moves more with heat. If you are unsure, SPC with an attached pad is the safer default; if comfort is the priority and the room is temperature-stable, WPC is more pleasant to live on.
Yes — it is the best mainstream finished floor for basements, because a vinyl core does not swell when damp. But fix any water entry first and test the slab: tape plastic sheet down for 24–48 hours, or use the RH or calcium chloride test the manufacturer specifies. Install a 6-mil polyethylene vapour barrier on the concrete unless the manufacturer accepts its attached pad instead, choose SPC for stability, and keep the space at roughly 45–55% relative humidity with a dehumidifier. A waterproof plank over a slab pushing moisture through still traps damp underneath, which leads to mould and odours.
The plank is; the floor is not. SPC and WPC cores contain no wood fibre, so spills, pet accidents and a leaking appliance will not swell or delaminate the planks. But a floating floor has joints and an expansion gap around the edge, and standing water will find its way through to the subfloor underneath. After a significant leak, click-lock planks can often be lifted, the subfloor dried, and the floor reinstalled. In bathrooms, seal the perimeter gap around the tub and toilet with silicone. Laminate, by contrast, is usually water-resistant: its fibreboard core swells if water reaches the edges.
No, and adding one usually causes problems. A second soft layer lets the click joints flex under foot traffic, which breaks the locking edges and opens gaps, and most manufacturers void the warranty if you add extra cushioning. The exception is a vapour barrier: on concrete, many manufacturers still require a thin 6-mil polyethylene sheet under a padded plank, because the pad itself is not rated as a moisture barrier. That is not cushioning, and it does not cause the flex problem. Check the installation guide for your specific collection.
Most rigid-core manufacturers specify within about 3/16 inch over 10 feet, and some add 1/8 inch over 6 feet. Check with a long straightedge in several directions. Fill dips with floor patch or self-levelling compound, and grind or sand high spots. Glue-down vinyl needs a flatter, smoother surface still, because thin planks telegraph every ridge and nail head. An out-of-tolerance subfloor is the most common cause of LVP problems: clicking underfoot, peaked or gapping joints and broken locks — none of which are covered by warranty when the floor is outside the stated tolerance.
Materials run roughly $1.50–$3 per square foot for entry SPC with a 6–12 mil wear layer, $3–$5 for mid-range 20–22 mil rigid core with an attached pad, and $4.50–$7 for premium lines. Professional click-lock installation adds about $1.50–$4 per square foot, bringing installed costs to roughly $3.50–$11. Commercial glue-down runs $7–$12 or more installed. Budget separately for old floor removal, levelling compound, trim, transitions and stair nosing, and order 10% extra for waste. The mid-range 20 mil category is where most homeowners get the best value.
Not properly. AC ratings (AC1–AC5) come from EN 13329, the European standard for laminate flooring, and describe abrasion and impact resistance for laminate's melamine surface. When an AC rating appears on a vinyl listing, it is borrowed terminology. For LVP, judge durability by the wear layer in mils, the EN ISO 10874 use class (23 is heavy domestic, 33 heavy commercial), and the warranty — a light-commercial warranty usually indicates a 20 mil-class product. For air quality, look for FloorScore certification and a stated phthalate-free formulation.
