Are you planning to install sustainable and stylish flooring in your home and wondering if cork flooring is waterproof? This eco-friendly and comfortable material has become a popular choice among homeowners seeking a natural, warm, and quiet living environment. But can cork truly withstand moisture in bathrooms and other damp areas?
In this guide, UK Flooring Depot explores the truth about cork flooring’s water resistance, how to install it safely in bathrooms, and what alternatives you might consider for high-moisture rooms.
Key Takeaways
Cork flooring is naturally water-resistant but not fully waterproof.
Proper installation, sealing, and maintenance are essential for long-term protection.
Glue-down cork floors perform better than floating click systems in damp spaces.
Eco-friendly sealants and finishes can enhance cork’s resistance to moisture.
Alternative waterproof options like Vinyl (LVT) or Waterproof Flooring may offer greater durability for bathrooms.
The Natural Qualities of Cork Flooring
Cork flooring is made from the bark of cork oak trees, a renewable resource that allows the trees to regrow after harvesting. This makes cork one of the most sustainable flooring materials available today. Its honeycomb-like cellular structure creates millions of air pockets, giving cork its signature softness, warmth, and sound insulation.
These characteristics make cork flooring ideal for living rooms and bedrooms, where comfort and quietness matter most. For an elegant alternative, you can also explore Real Wood Flooring or our timeless Herringbone & Parquet designs to add natural charm to your home.
Is Cork Flooring Waterproof or Water-Resistant?
The terms “waterproof” and “water-resistant” are often confused, but they mean very different things. Waterproof flooring can handle continuous exposure to water, while water-resistant flooring can repel moisture for a limited time.
Cork contains suberin, a natural waxy substance that repels water—one reason cork is used in bottle stoppers. However, when cork is manufactured into tiles or planks with seams, its ability to resist water depends heavily on the quality of sealing and installation. Floating cork floors that use HDF (High-Density Fibreboard) cores are particularly vulnerable if moisture seeps into the joints.
For rooms that experience regular humidity, such as bathrooms and kitchens, cork can be used safely only when it’s properly sealed and installed using the right method.
Choosing the Right Cork Flooring for Moisture-Prone Areas
Fully Glued Cork Flooring
For bathrooms or wet areas, fully glued cork flooring offers the best protection. The adhesive creates a tight bond between the floor and the subfloor, minimising gaps where water could enter. This method also prevents lifting and swelling caused by fluctuating humidity levels. Just like installing Vinyl (LVT), proper preparation of the subfloor is essential for long-lasting performance.
Floating Cork Flooring
Floating cork floors are easier to install thanks to their click-lock systems, but they’re less water-resistant. Even small gaps along the edges can allow moisture to penetrate. If you choose floating cork, applying a high-quality waterproof sealant after installation can improve its resistance. Alternatively, consider Waterproof Flooring options that are specifically engineered to handle humidity and spills without damage.
How to Seal Cork Flooring
Sealing cork flooring is key to enhancing its water resistance. Most cork floors come pre-finished with a protective layer, but an additional coat after installation provides better moisture protection.
Use eco-friendly polyurethane, natural oils, or water-based varnishes that maintain cork’s natural look while protecting it from water absorption. Regular maintenance is equally important—clean spills immediately, avoid soaking the floor when mopping, and reseal periodically to maintain durability.
For those who love natural finishes, the same sealing techniques are often applied to Real Wood Flooring or Herringbone & Parquet to preserve their texture and longevity.
Cork Flooring with Vinyl Layers
Some modern cork floors combine cork with vinyl layers to improve moisture resistance. These vinyl-cork hybrid floors offer the comfort of cork with the durability and waterproofing of vinyl. This makes them an excellent choice for bathrooms, kitchens, or utility rooms.
However, if full waterproofing is your priority, traditional Vinyl (LVT) or Laminate Flooring collections provide a wider variety of waterproof and easy-to-maintain styles, from wood effects to stone textures.
Best Rooms for Cork Flooring
Cork flooring truly shines in dry living spaces where comfort and insulation are priorities. It’s perfect for living rooms, bedrooms, and home offices, where it provides warmth, quietness, and eco-friendly beauty.

FAQs
Is cork flooring suitable for bathrooms?
Yes, cork flooring can be used in bathrooms if it’s glued down and properly sealed. Floating cork floors are not ideal unless fully waterproofed after installation.
Does cork flooring swell when wet?
If exposed to standing water or high humidity, unsealed cork can swell or warp. Sealing the floor and wiping up spills quickly prevents this issue.
How long does cork flooring last?
With proper installation and care, cork flooring can last over 25 years while maintaining its comfort, warmth, and natural charm.
Can cork flooring be refinished?
Yes. Just like Real Wood Flooring, cork flooring can be lightly sanded and resealed to refresh its surface and extend its lifespan.
Summary
Cork flooring is naturally water-resistant, sustainable, and exceptionally comfortable underfoot. While not entirely waterproof, it can perform beautifully in bathrooms and kitchens when properly sealed and installed using a glue-down method. For areas exposed to heavy moisture, consider alternatives like Vinyl (LVT), Laminate, or Waterproof Flooring for complete peace of mind.
