Design That Stands on Its Own

Proven stability for creative bathroom concepts beyond the heavy and the ordinary: lightweight waterproof solutions and the smart construction behind floating lines and long spans.

In contemporary bathroom architecture, the ability to build freely - without bulky substructures, visible reinforcements, or reliance on ceiling fixings - has become a mark of both technical expertise and design maturity. Architects and interior designers are seeking solutions that allow space to feel lighter, clearer, and more intentional. And this is precisely where wedi’s newest system developments redefine what is possible.

Lightweight design. Stable performance.

With a high-density, closed-cell XPS core, wedi building boards and modules combine remarkably low weight with proven, enduring waterproof performance. This duality - light enough to handle effortlessly, yet strong enough to support long spans - creates new opportunities for creative bathroom planning. Walls and modules can be positioned where they make the most architectural sense, rather than where the building’s structure dictates.

Traditionally, extending freestanding partitions in wet areas meant compromise such as excessive reinforcement, metal framing, or ceiling connection. wedi breaks this pattern by setting a new benchmark for unsupported length: just two building boards with a thickness of only 80mm are enough to construct a freestanding wall up to 1800mm long and 2600mm high, with remarkable structural stability. wedi XL and XXL building boards provide the perfect solution. “Our lightweight partitions strike the perfect balance between design freedom and technical reliability,” says Andrew Watkins, Technical Manager at wedi UK. “We guarantee stability up to a length of 1.8 metre – without any additional reinforcement or ceiling support.” The result is a cleaner architectural language: long, uninterrupted planes that appear to rise effortlessly from the floor.

Walls that stand alone. Unsupported, uncompromised.

Shower partitions typically require more than a simple dividing wall. While wedi building bords from 80 mm thickness can be milled or prefabricated on site to accommodate niches or service runs, the final performance still depends heavily on workmanship. To ensure reliable outcomes in wet-room design, wedi also provides ready-to-install wall elements with factory-integrated technology - such as Hansgrohe iBox, preinstalled hot and cold pipes, or built-in storage niches - offering architects a secure, specification-led solution. All wall modules can be seamlessly integrated into partitions using standard wedi building boards of matching thickness, creating a light yet structurally robust, interlocking construction without ceiling support or supplemental reinforcement up to 1.8m in length. The result is a refined, functionally resolved design delivered through a fully coordinated wedi system solution

Compact footprint. Full-scale performance.

Small spaces often demand the highest degree of planning intelligence. “Our newest wall element the Sanwell XS shower module delivers exactly that - a slimline, ready-to-tile solution that includes the required hot and cold-water pipes as well as the reinforcement for on site installation of a shower rod,” highlights Watkins. “At only 300mm wide and 50mm thick, it is practical and easy to integrate into even the smallest spaces”. The new module offers an extremely compact system solution for shower back wall design with surface-mounted fittings as well as straightforward installation and enduring waterproof performance.

Creating the perfect curve to meet the goal at just the right angle — what makes football fans' hearts beat faster is also shaping modern bathroom design; here, too, it’s all about movement, as softly contoured shower walls create elegant, fluid transitions that invite you further into the space. Bringing organic forms to life in wet areas however requires more than vision, efficient and reliable construction is essential. Built on decades of knowledge and trust, wedi solutions ensure that every curve is as breathtaking as it is watertight. Cut, shape, bend: flexible and easy to work with, wedi Construct building boards enable designers to shape bathroom structures with precision and confidence, knowing that every feature is backed by predictable stability and a fully certificated system. For architects who value both aesthetic clarity and technical certainty, this brings a whole new level of design freedom.

Design. Trust. Build.

Backed by proven performance, wedi’s 100% waterproof building systems bring visionary designs to life without structural compromise. “What distinguishes our solutions is their cohesion. Every element is engineered to interlock seamlessly, reducing risk during installation and ensuring long-term security in humid, high-load environments,” - concludes Andrew Watkins, Technical Manager at wedi UK. “For specifiers and planners, this system reliability translates directly into trust: trust in the build quality, trust in long-term performance, and trust that creative concepts can be executed exactly as intended.” Backed by 43 years of expertise, wedi empowers the creation of unsupported forms with its fully coordinated system solutions turning compact construction spaces into surprisingly expansive and expressive design opportunities.
