Luxury vinyl plank (LVP) flooring has surged in popularity largely because of its reputation as a waterproof flooring option — but the full story is a bit more nuanced.
The Short Answer: Yes, But With Caveats
The planks themselves are 100% waterproof. LVP is made from synthetic PVC materials, meaning the planks will not warp, swell, or absorb water the way hardwood or laminate can. Spills, splashes, and even pet accidents can be wiped up without damaging the surface.
Where It Gets Complicated
While the planks themselves are waterproof, that doesn't mean water can be ignored entirely. Allowing water to sit on top of the floor for extended periods, or permitting moisture to work its way underneath the planks over time, can lead to serious problems. Standing water can eventually find its way through the seams, and once moisture becomes trapped beneath the floor it can cause your flooring to wave and buckle, and create a host of other problems with the subfloor underneath. Waterproof planks protect against everyday spills and splashes, but they are not a green light to let water go unaddressed. Promptly cleaning up spills and keeping moisture from building up beneath the floor are just as important as the flooring material itself.
Are All Vinyl Plank Floors Waterproof?
Not all vinyl plank is created equal. There are a few distinctions to be aware of:
• LVP (Luxury Vinyl Plank) — Fully waterproof planks at the surface level.
• Standard/budget vinyl plank —Generally waterproof at the plank level, but may have thinner wear layers and less durable construction.
• WPC (Wood Plastic Composite) — Despite being marketed alongside waterproof flooring, WPC contains wood fiber in its core, which can absorb moisture over time. Buyers should be cautious — it is not a truly waterproof floor and is better described as water-resistant at best. Prolonged exposure to moisture can cause the core to swell or break down.
• SPC (Stone Plastic Composite) — A fully waterproof rigid core option. Its limestone and PVC core contains no wood fiber, making it far more resistant to moisture than WPC and a better choice for high-humidity or wet areas.
Best Uses for Waterproof LVP
LVP is an excellent choice for moisture-prone areas like kitchens, bathrooms, laundry rooms, and basements. For the best protection, look for products marketed as "waterproof" (not just "water-resistant"), use waterproof underlayment, and seal the perimeter edges where the floor meets walls.
The Bottom Line
Vinyl plank flooring is one of the most water-resistant flooring options on the market, and in most cases it is genuinely waterproof at the plank level. Just remember — proper installation matters just as much as the product itself when it comes to keeping moisture from becoming a long-term problem.
