Modular construction with wedi
Specialists are scarce, schedules are getting tighter, demands are increasing: Modular construction also opens up new paths for bathrooms and wet rooms. Complete bathroom modules are the key to this, which are already manufactured in the production hall and delivered to the construction site prefabricated.
The extensive prefabrication in controlled production environments makes it possible to implement bathroom projects faster, more cost-effectively and with high quality. Wedi has been an active member of the German Prefab Building Association (BDF) for over 10 years and is the system supplier for the sealing of bathrooms for numerous prefabricated house manufacturers and bathroom module builders. In addition, wedi offers prefabricated, customer-specific room construction for the creation of bathrooms. Prefabricated shower partitions up to Complete Construction Kits for bathroom modules are possible here.

Lead by ARDEX: Modular construction at wedi
Wedi offers high-quality and efficient solutions for modular and wet rooms that can be perfectly integrated into modular construction projects. Whether for bathrooms and bathrooms in hotels, residential homes or other projects: The prefabricated and high-quality sealing systems from wedi are perfect wherever fast and flexible construction methods are required. In addition, there are a number of innovative and sustainable system solutions for modular construction.
As part of the ARDEX Group, wedi also benefits from many years of experience and innovative strength in the field of Prefab Modular Offsite. With its many brands, the ARDEX Group offers a comprehensive portfolio of construction products for the fast, efficient and sustainable realization of modular construction projects. The close cooperation within the group is a clear plus – also for industry, project developers and crafts.

Modular construction Not always, but more and more often
Modular solutions have a future – but it depends on the individual case. They are not suitable for every bathroom and wet room project. But there is a growing number of applications where modular construction can be useful.
- For hotels, student residences and apartment buildings: In a construction project are the requirements for wet rooms high? Then the industrially prefabricated solutions from wedi are the right answer. They enable efficient and high-quality implementation and can significantly accelerate the construction process.
- For prefabricated house builders and modular construction companies: A company wants fast and safe bath sealing. Wedi supplies products adapted to customers and production processes – from wall to floor sealing. In this way, we enable a high degree of prefabrication.
- For architects and planners : Is there a bathroom renovation or refurbishment in the pipeline? Or the new construction of bathrooms with modern wellness elements? Wedi supports with pre-fabricated shower and wet room modules. We work closely with architects and planning managers. And we are flexible: This allows us to adapt modules precisely to specific project requirements.
Modular construction: Three solutions, a thousand possibilities
- Modular Construction Kits : wedi offers factory-sealed and tailor-made construction kits for bathrooms and wet rooms. These have integrated sanitary technology such as drains and shower fittings. Modular Construction Kits can be installed on site in a short time, speeding up and simplifying the construction process.
- System Solutions for Modular Construction: wedi provides a wide range of products and systems. These are particularly suitable for wood module construction and other lightweight constructions.
- Customisable Each construction project has its own requirements. That is why we adapt the wet room solutions exactly to this. Of course, without any compromise in quality or efficiency.

Efficient, safe, sustainable: Advantages of modular construction
- Fast and precise: Factory prefabrication and ready-to-install modules significantly reduce construction time. All elements are tailor-made and can be installed quickly – so everything runs smoothly on the construction site.
- Waterproof and safe: The wedi modules are 100% waterproof and offer high resistance to moisture. This makes them particularly suitable for Wet Rooms in modular buildings.
- Sustainable and resource-saving: wedi relies on resource-saving processes and materials. This modular design reduces waste, saves energy and contributes to meeting the EU's sustainability goals.
Wedi for modular construction and prefab
Modular construction and prefab: Both aim at efficient and time-saving drains on the construction site. The difference loungers in the degree of prefabrication.
- Complete bath modules are prefabricated and delivered to the construction site in modular construction. The contracted companies can then easily position them on site – with all the advantages mentioned above.
- PreFab involves prefabricating individual components. An example of this is the wedi Sanwell shower wall module: Cold and hot water pipes are pre-installed, and the Hansgrohe iBox for more than 200 flush-mounted fittings is already installed in the factory. This saves time on site and increases reliability.

Solution for 38 bathrooms: Practical example for modular construction
The St. Peter-Ording beach clinic has the whole person in view. This includes an ambience in which patients feel comfortable: In other words, also modern bathrooms.
In the course of the hospital expansion, a total of 38 new bathrooms were to be built for the patients. That called for efficiency – and wedi. The shower area, the mounting for the wash stand, the toilet device and the preparation for electrical and lighting components should be pre-fabricated at the factory. How did you do this with existing base products?
