LVT flooring is incredibly popular — and for good reason. It’s stylish, durable, and highly resistant to moisture. But how waterproof is it really? And what happens if water gets under the floor, for example during a leak?
In this article, we explain everything clearly and simply.
Is an LVT floor water-resistant? Yes — with important conditions
The material itself is fully water-resistant. Daily spills, wet shoes, cleaning, pets — LVT can handle it all.
But in cases of heavy water exposure, such as a serious leak or flooding, the situation changes. Not because the LVT gets damaged, but because the subfloor and adhesive can be affected.
The LVT remains intact, but the glue bond can weaken, causing tiles or planks to lift, bubble, or shift.
That’s why quick action during water damage is essential.
How can water damage an LVT floor?
1. Water underneath the floor
During a leak, water may seep below the LVT. If the adhesive gets wet, it can lose strength, and the floor may detach or form bubbles.
2. Warping or movement from long-term moisture
LVT does not swell like wood, but prolonged standing water can still cause deformation or raised edges, especially if moisture enters through small openings.
What affects the water resistance of LVT flooring?
✔ Floor thickness
Thicker LVT is generally more stable and resistant to movement.
✔ Correct type of installation
Glue-down LVT is ideal for kitchens, bathrooms and commercial spaces — as long as it’s installed professionally.
✔ Condition of the subfloor
A level, dry, solid subfloor is crucial.
Moisture in the subfloor = risk of debonding.
✔ Installation quality
A precise, professional installation prevents gaps where water can seep through.
What should you do in case of a leak?
-
Remove standing water immediately
-
Allow both the LVT and the subfloor to dry completely
-
Ventilate to prevent mould
-
Unsure about the damage? → Have a specialist check the adhesive and subfloor
LVT is tough, but long-term moisture exposure is never ideal.
Conclusion
LVT is an excellent flooring choice for kitchens, bathrooms, coastal properties and even yachts. The material itself is highly water-resistant.
However, in extreme situations like leaks or flooding, the subfloor or adhesive layer may be affected.
With proper installation and quick action during water exposure, an LVT floor will stay beautiful for many years — even after a surprising leak.
