Understand LVP

Start your vinyl plank vs tile decision here. Luxury vinyl plank (LVP) is a multi-layer floor that looks like wood (or stone) but is mostly vinyl and a rigid or flexible core. Knowing the layers — and where thin products fail — keeps you from buying the wrong box for the room.

What LVP actually is

From the top down you usually have: a clear wear layer, a printed design film, a core (the stiff “body”), and often an attached foam pad on the bottom. Total thickness (for example 6 mm or 12 mm) is not the same as wear-layer thickness (measured in mils — thousandths of an inch).

Rigid core vs flexible

Rigid core (SPC / WPC)

SPC (stone plastic / rigid polymer) and WPC (wood plastic) cores stay flatter, dent less under chairs, and are the usual DIY click-lock choice today. SPC is typically denser and more stable; WPC can feel a bit warmer underfoot.

Flexible vinyl

Older or budget glue-down / loose-lay sheets and planks bend easily. They can look great when installed well, but they need a flatter, cleaner substrate and are less forgiving for first-time DIY than rigid click-lock.

Wear layers (mils) — use cases

Wear layer protects the print; it does not make a thin core behave like a thick one under heavy loads.

Thickness by use — and where each fails

Box labels advertise total thickness. Thicker rigid cores usually feel better and hide minor subfloor waves better — but no residential LVP is magic. Here’s the honest take:

~6 mm

Often entry-level rigid or older flexible builds. Fine for low-traffic bedrooms if the subfloor is excellent.

Fails in: garages (temperature swings + vehicle loads); also weak long-term in busy family homes — dents, broken locks, telegraphing.

~8–10 mm

Common midrange DIY. Comfortable for most homes when wear layer and prep are solid.

~10 mm can struggle under heavy furniture, rolling loads (office chairs, carts), or commercial-adjacent / very high-traffic spaces.

~12 mm+

Safer match for active family homes, larger rooms, and slightly imperfect (but still in-spec) subfloors.

Still follow flatness and moisture rules — thicker does not forgive a wet slab.

~20 mm premium

Top-tier residential build for comfort and stability when loads and traffic are high.

Choose when you want maximum underfoot feel and margin — not a substitute for garage-rated products.
What buying too thin looks like: you see and feel ridges from the subfloor (telegraphing), click joints that crack or won’t stay locked, chair dents, edges that peak or cup, and the printed design wearing through early in traffic lanes.
Garages: standard residential LVP is usually the wrong category. Cold/hot swings, tire loads, and oil call for products made for garages (or epoxy / specialty systems) — not a 6 mm living-room plank. When in doubt, ask the manufacturer if the SKU is garage-rated before you buy.

Waterproof vs water-resistant

“Waterproof” usually means the plank won’t swell like laminate or hardwood when wet. It does not mean floods are fine, or that water trapped under a floating floor is harmless. Edges, transitions, and the subfloor still matter. Standing water can ruin trim, walls, and warranties.

Click-lock vs glue-down

Underlayment: attached vs separate

Many rigid planks ship with foam already glued on. Don’t add a second thick pad unless the manufacturer allows it — double padding can void warranties and make locks fail. Separate underlayment or a vapor barrier is used when the brand requires it (especially over concrete). Always match the written install instructions for that SKU.
