Why HPL Is 100% Waterproof – Tested in UAE Conditions

When it comes to washrooms and locker rooms in the UAE, waterproof performance is not optional—it’s a requirement. From high humidity in coastal areas like Dubai and Sharjah to constant floor washing in malls, schools, and offices, washroom materials get tested every single day. That’s why HPL (High Pressure Laminate), also called compact laminate or phenolic board, is considered one of the best waterproof partition materials in the UAE.

What Is HPL (High Pressure Laminate)?

HPL stands for High Pressure Laminate. It’s a compact board made by pressing multiple layers of kraft paper soaked in resin under extremely high heat and pressure. The result is a dense, solid and non-porous sheet that does not absorb water.

• Toilet cubicle doors and panels
• Washroom partitions
• Changing room cubicles
• Gym and school lockers
• Shower partitions

Why HPL Is 100% Waterproof (The Real Science)

HPL is waterproof because it is sealed through its full thickness—not only on the surface. The resin penetrates the paper layers and becomes a solid, compact mass when pressed. This structure blocks water penetration and prevents swelling.

• Resin-saturated core (no loose fibers to soak moisture)
• High density created under pressure
• Non-porous structure that blocks water entry
• No swelling or softening like wood-based materials

How UAE Climate Tests Washroom Materials

The UAE environment is harsh for washrooms. Many materials fail due to humidity, repeated wet cleaning, heavy usage, and temperature shifts between AC interiors and warmer external areas.

1. High humidity (especially coastal Dubai/Sharjah)
2. Constant cleaning with water + disinfectants
3. High footfall in malls, schools, gyms, offices
4. Temperature variation causing warping in weak boards

HPL vs MDF / Plywood: Why HPL Wins in Wet Areas

MDF and plywood can look good initially, but they are not truly waterproof unless fully sealed—edges and screw holes become weak points. HPL compact laminate stays stable because its entire thickness is water-resistant.

• HPL does not absorb water through edges
• HPL does not swell in humidity
• HPL remains stable with frequent floor washing
• HPL lasts longer in public washrooms

Where HPL Is Commonly Used in UAE Projects

HPL is widely used in UAE commercial projects due to durability, hygiene, and premium looks.

• Luxury mall washrooms
• Office washrooms (Business Bay, DIFC, Downtown)
• Schools and universities
• Gym and fitness locker rooms
• Hotels and hospitality projects
• High-traffic public washrooms

Is HPL Safe for Shower Areas and Wet Rooms?

Yes. HPL compact laminate is suitable for shower partitions and changing rooms because it resists direct water exposure and maintains shape. For best results: select the right thickness, use waterproof-grade hardware, and ensure proper drainage and installation.

Does HPL Get Damaged by Cleaning Chemicals?

HPL is highly resistant to common washroom cleaners and disinfectants used in UAE facilities. Avoid extremely abrasive pads and harsh acids for long-term surface protection.

How We Test HPL Performance in UAE Conditions

At Royal Cubicles, our project experience across the UAE shows that correctly installed HPL panels stay firm in high humidity, do not swell at edges, and maintain color/finish after repeated cleaning—making HPL a long-term solution.

Choosing the Right HPL Thickness

Common thickness guide for UAE projects:

• 12mm: Popular for toilet cubicle doors and partitions
• 18mm: Extra rigidity for heavy-traffic commercial areas
• 6–10mm: Used for specific design needs or backing

Why HPL Toilet Cubicles Are the Best Choice in UAE

If you need a washroom solution that survives humidity, frequent cleaning, and heavy daily use, HPL compact laminate is one of the most reliable materials available in the UAE.
