TOPCRET – CLAY
Clay Plaster Bathroom: Style, Sustainability & Waterproofing
Think your bathroom can’t have natural textures, breathable materials, and modern durability? Think again. With Clay® by TOPCRET, your next bathroom renovation doesn’t have to choose between wellness, aesthetics, and practicality.
Clay plaster in bathrooms isn’t just a trend—it’s a shift toward cleaner air, softer spaces, and seamless finishes that calm the mind and resist water. Curious? Let’s explore why Clay® is the game-changer your bathroom’s been waiting for.
Why Clay in the Bathroom?
Redefining What's Possible: Clay in Wet Areas
For years, clay plaster was off-limits for bathrooms—too sensitive to moisture. But Clay shatters that myth with a dual-system finish that includes Hydro+, making it waterproof before sealing. That’s right—you can now use clay in showers, backsplashes, even full wet rooms.
Introducing Hydro+: Waterproof Before Sealers
Most waterproof finishes are synthetic, sealed with chemicals or require constant maintenance. Clay® with Hydro+ is naturally breathable and prepped for water, eliminating the need for toxic treatments while keeping your walls healthy and dry.
Benefits of a Clay Bathroom
VOC-Free & Breathable: A Healthier Washroom
Bathrooms are often filled with humidity and synthetic materials. Clay® changes that. It’s VOC-free, naturally breathable, and helps regulate humidity—perfect for preventing mould and stale air.
Seamless from Floor to Wall
Tiles have grout lines. Paint peels. But Clay creates a continuous surface from floor to wall, delivering that sleek, spa-like finish every modern bathroom needs.
Natural Insulation & Comfort
Clay doesn’t just look good—it feels good. It provides a natural warmth underfoot and reduces noise, creating a peaceful space for everyday rituals.
Design Possibilities with Clay
Textures Made for Spa-Like Ambience
Clay® comes in four textures:
S (Smooth): sleek and modern
M (Medium): balanced and soft
L (Layered): tactile and earthy
XL (Rustic): bold, expressive texture
Each finish pairs beautifully with stone, wood, or minimalist bathroom furniture, offering that “wrapped in clay” feeling designers love.
Colours Inspired by Nature
Over 60 nature-inspired shades, from warm terracotta to calm stone greys, let you create the atmosphere you crave. Prefer custom? The “Paint to Sample” programme means your bathroom can match your exact tone.
Installation & Durability
No Demolition Needed
Renovating doesn’t have to mean tearing down walls. Clay® can be applied over existing substrates, including tiles, making it perfect for quick yet high-impact upgrades.
Built to Withstand Daily Moisture
Unlike traditional plasters that crack or fade, Clay stands up to the realities of daily use. It’s even more durable than microcement in wet areas—yes, really.
Clay vs Other Bathroom Finishes
Tiles, Cement, and Tadelakt
Tiles: prone to mouldy grout and cold aesthetics.
Cement: durable but industrial, and not breathable.
Tadelakt: beautiful but requires burnishing, waxing, and expert labour.
Why Not Tiles or Cement?
Tiles are classic—but prone to grime and maintenance. Cement? Too cold and industrial. Clay offers a warmer, more tactile alternative with no compromise on durability.
Why Clay® Wins the Comparison
Clay® brings the handcrafted look of tadelakt, the durability of cement, and the natural benefits of raw earth—without the complexity. No wax. No polish. No compromises.
