LVP vs laminate flooring for a Florida house on a slab

If your floor sits on a concrete slab and water ever reaches it, the LVP vs laminate question has a short answer: luxury vinyl plank takes standing water and slab moisture, and laminate does not, because laminate's core is wood fibre. Laminate still earns its place in dry rooms, where its harder surface and firmer feel are worth having.

We install both, so this is not a pitch for one of them. It is where each one belongs in a Sarasota or Bradenton house, and what to ask before you choose.

What is the difference between LVP and laminate?

Both are plank floors that usually click together and float, and both show a printed picture of wood under a clear top layer. What sits under that picture is the difference, and it is the part you never see once the floor is down.

Laminate is built on a core of high-density fibreboard: wood fibre pressed hard with resin. The wood grain is printed on a paper layer, and a hard, clear melamine coat over it takes the wear. That top coat is why laminate is known for shrugging off scratches.

Luxury vinyl plank is plastic all the way through. The planks that suit a house on a slab have a rigid core, usually stone-polymer composite, or SPC, which is mineral-filled and does not absorb water. Over it sit the printed layer and a clear vinyl wear layer, measured in mils.

Is laminate waterproof?

The surface of a laminate board sheds a spill if you wipe it up. The core does not forgive water that gets into it. Fibreboard that soaks up water through a seam or a cut edge swells, and once it has swollen it does not go back down: the joints rise into ridges, and the boards have to be replaced.

Some laminate is sold as water-resistant, with sealed edges and treated cores that hold off a spill for longer. Read the manufacturer's own terms for what that label covers. A promise about spills on top says nothing about water coming up from underneath, and in a Florida house on a slab, that is the water to plan for.

That core is why the best flooring for a Florida house puts standard laminate on the short list of floors that struggle on a slab, and why it sends wet rooms to vinyl or tile instead.

Why does the slab decide so much?

Most houses here sit on a concrete slab on grade, and concrete passes moisture up from the ground as vapour all year, whether or not the surface looks dry. A floating floor sits right on top of that, with only an underlayment and a plastic moisture barrier in between.

An SPC vinyl plank does not care about that vapour. A laminate board needs the barrier under it to do its job perfectly for as long as the floor is down, in a house with a pool, sliders open half the year and a storm season. That is a lot to ask of a thin sheet of plastic.

Vinyl is not a reason to skip the slab, either. Water that sits under any floating floor has nowhere to go, and adhesives fail when the slab is still giving up moisture. Why floors fail in Florida houses explains the moisture test and what to do when a slab reads high, and it is worth reading before you buy either floor.

Where does LVP make more sense?

Anywhere water can reach the floor: the kitchen, the hall to the sliders, the room off the lanai, a rental, or a house that is shut up for the summer and opened again in the fall. Rigid-core vinyl is the floating floor that does not mind a wet towel, a dripping swimsuit or a leak nobody finds until Monday.

It is also warmer and quieter underfoot than tile, softer to stand on for long stretches in a kitchen, and more forgiving of a slab that is not perfectly flat. Those are the reasons luxury vinyl plank sits beside porcelain at the top of the flooring we install for Florida houses.

The number to ask for is the wear layer, in mils. Every vinyl plank looks the same in the box. A wear layer around 12 mil is a reasonable residential floor; 20 mil and above is what belongs in a house with dogs, sand and a door to the pool. If a supplier does not tell you the figure, ask for it.

Where does laminate still make sense?

In rooms that stay dry, laminate's strengths come forward. Bedrooms, a home office and an upstairs living room rarely see standing water, and there the question is wear and feel rather than water.

The melamine top coat on laminate is generally harder than a vinyl wear layer, which is why laminate is the one known for resisting scratches from chair legs, sand from the beach and a dog's claws on a run down the hall. In a dry room with that kind of traffic, it is a fair choice.

It also feels more like a wood floor. A laminate board is stiffer than a vinyl plank, so it sounds and feels firmer underfoot, and the better boards carry an embossed texture that follows the printed grain. Some people prefer that; others prefer the softer, quieter vinyl. Stand on both before you decide.

Sun is one more point to weigh. Vinyl moves with temperature more than a fibreboard core does, so a vinyl floor in front of a west-facing slider in full afternoon sun needs the expansion room its manufacturer specifies. That is an install detail rather than a reason to rule vinyl out, but it is worth knowing about a sunny room.

How are LVP and laminate installed over a concrete slab?

Both are usually floated: the planks lock to each other, not to the slab, over an underlayment. Laminate on concrete needs a moisture barrier under it. Many rigid-core vinyl planks come with a pad attached, and the manufacturer's instructions say whether a separate barrier is still required.

Both need a gap at the walls, hidden under the baseboard, so the floor can expand and contract. A floating floor pinned at the edges by cabinets, tight trim or a heavy island has nowhere to go, and that is where ridges and gaps start. Both also need a flat slab: a plank that bridges a dip flexes every time someone steps on it, and the joints wear.

Getting the slab flat and dry is most of the job, and it is the part no label on a box can do for you. Removing the old floor, levelling the slab and installing the new one is one job for our crew, so there is no gap between trades for something to go wrong in.

What if you want real wood instead?

Neither LVP nor laminate is wood on top; both are a photograph of it. If the wood itself is the point, the wood floor that belongs on a slab here is engineered, with a real oak wear layer over a cross-laminated core. Riva Spain engineered hardwood is what we install, and choosing it is a different conversation, about the wear layer and the air in the house rather than about standing water.

And for a bathroom or a laundry room, the answer is neither. A room that gets truly wet wants tile, and porcelain tile is indifferent to water in a way no floating floor is.

LVP vs laminate: how to choose, room by room

1. Will water ever stand on it? The kitchen, the room off the lanai, a house that sits empty for the summer: LVP with a rigid core.
2. Is it a dry room where scratches and feel matter most? A bedroom, an office, an upstairs room: laminate is a fair choice.
3. Is it a bathroom or a laundry? Tile.
4. What does the slab read? A high reading points to vinyl or tile, or to treating the slab before anything goes down.
5. How thick is the wear layer? For vinyl, ask for the mil figure. For laminate, ask for the abrasion rating the manufacturer publishes.

The quickest way to settle it is to put both under your feet. The racks in our Bradenton showroom hold wood-look planks you can lift out, compare side by side and take home to see in your own light, next to the tile and wood you might be weighing them against.
