The Future of Wetrooms: Why System‑Led Design Defines Modern Performance By Ian Cartwright, Wall Protection Specialist
Why Detailing Now Defines Performance
In my work across NHS estates, leisure facilities, student accommodation and hospitality, I see one truth repeated time and again: wetrooms are pushed far beyond what most people imagine. Persistent moisture, harsh cleaning chemicals and relentless footfall expose every weakness in the build‑up.
And from a specialist’s perspective, the pattern is clear.
Most wetroom failures don’t start on the surface. They begin in the junctions, corners and transitions where detailing either protects the space for years or allows failure to creep in within months.
A modern wetroom isn’t a loose collection of products. It’s a coherent, engineered system where hygienic wall protection, coving components and slip‑resistant flooring work together to deliver predictable, long‑term waterproof performance.
Key Performance Criteria
In the UK, wetrooms are expected to meet performance requirements relating to waterproofing, drainage, slip resistance, structural integrity and accessibility. There’s no single wetroom‑specific guidance, so compliance is achieved through a combination of Building Regulations and British Standards.
A well‑performing UK wetroom should:
• Remain watertight
• Drain effectively without pooling
• Prevent water escape
• Provide slip resistance
• Avoid moisture damage or mould
• Comply with applicable Building Regulations and BS 5385 guidance
The Wetroom System Required
To meet these expectations, specifiers can now turn to one trusted supplier capable of delivering a coordinated, compatible system.
The combined wetroom solution from Gradus and Gerflor brings together:
• Gradus SureProtect Pure hygienic wall cladding
• Gradus Cove Formers & Clean Corner Systems
• Gerflor Tarasafe H2O slip‑resistant safety flooring
This system‑led approach is what ensures every interface, wall, floor, junction and transition - works together rather than against each other.
Materials That Elevate the Envelope
SureProtect Pure
SureProtect Pure is a proven wetroom wall‑cladding solution. It provides a seamless, impervious surface ideal for healthcare, leisure and commercial environments. It eliminates moisture ingress, supports infection‑control protocols and delivers a durable, easy‑clean finish.
Specifiers can explore the full range in the Gradus Wall Protection Catalogue or speak directly with the Gradus wall protection specialists for project‑specific guidance.
Tarasafe H2O Slip‑Resistant Flooring
Tarasafe H2O offers:
• Sustainable slip resistance
• Heat‑welded seams for watertight integrity
• Compatibility with coved transitions
• Proven performance across NHS estates, leisure facilities and student accommodation
Gradus Cove Formers & Clean Corner Systems
These components address the most common wetroom failure points. By removing 90° angles where the wall and floor meet, they create smooth, hygienic junctions that support wall‑to‑floor waterproofing and reduce the risk of water ingress.
Together, these materials form a fully integrated wetroom system engineered for long‑term commercial performance.
The Effectiveness of the Combined Solution
When SureProtect Pure, Cove Formers, Clean Corners and Tarasafe H2O are installed as a coordinated system, the wetroom performs as intended- not just on day one, but throughout its lifecycle.
This combined solution delivers:
• Predictable waterproofing integrity
• Improved hygiene and infection control
• Reduced maintenance interventions
• Greater durability under heavy use
• Confidence for estates teams and contractors
It’s a system designed to withstand real‑world operational pressures.
Benefits of the Complete System
A coordinated, system‑led approach results in a wetroom that is:
• Fully waterproof
• Hygienic and easy to maintain
• Slip resistant and safe
• Protected at every junction
• Built for long‑term commercial performance
This is wetroom design that is engineered to last, not simply installed to look good.
When the System Works, the Space Works
A wetroom built as a complete system performs better, lasts longer and protects the building fabric more effectively. For NHS estates, leisure facilities, student accommodation and care facilities, this approach reduces risk, simplifies specification and ensures consistent, repeatable performance.
When the system works, the space works.
FAQs
What is system‑led wetroom design?
A design approach where wall protection, flooring, coving and waterproofing layers work as one integrated system.
Why do wetrooms fail in commercial buildings?
Failures typically occur at transitions, corners and junctions.
What flooring is best for wetrooms?
Slip‑resistant, heat‑welded flooring such as Tarasafe H2O ensures watertight performance.
How do you create hygienic wetroom walls?
Use seamless, impervious wall protection like SureProtect Pure to eliminate moisture ingress.
What are cove formers and clean corners?
They remove 90° angles at the wall‑and‑floor join, creating hygienic, easy‑clean transitions that support waterproofing integrity.
