wedi Fundo Flex channel element – flexible base for free drain positioning
✔️ Free drain positioning ✔️ Low installation height ✔️ Modular system ✔️ 100% waterproof ✔️ Suitable for timber and concrete floors
The wedi Fundo Flex channel element is the core component of the modular Fundo Flex system and enables free positioning of the drain within the shower floor. This element is used when standard shower trays with fixed drain positions are not suitable due to floor joists, pipework or specific design requirements. Thanks to its low installation height and waterproof XPS construction, the channel element is ideal for both renovation projects and new-build applications.
When do you choose the Fundo Flex channel element?
The channel element is used in situations where maximum flexibility is required for positioning the shower drain. When combined with the corresponding slope boards, shower channel and Wave drain, it creates a technically reliable and fully waterproof shower solution without the need for major modifications to the floor structure.

wedi Fundo Flex – the modular system for maximum freedom in drain positioning
The wedi Fundo Flex is a modular shower floor system developed for situations where a fixed drain position is not possible or desirable. The Fundo Flex channel element forms the technical core of the system and allows the drain to be positioned exactly where the floor structure and bathroom design require it. This makes the system ideal for renovations, bespoke solutions and bathrooms with complex floor constructions.
Free drain placement without compromise
With many standard shower floors, the drain position is fixed, often leading to extensive modifications to joists, pipework or structural elements. The wedi Fundo Flex channel element eliminates these limitations. In combination with the matching sloping panels and shower channel, the drain can be positioned against the wall, away from the wall or even centrally within the shower area. This keeps the design in control, without technical restrictions.
Free positioning of the shower channel
Ideal for joists, pipework and structural obstacles
Suitable for renovation and new-build projects
Compatible with timber and concrete floors
Technical foundation of the Fundo Flex system
The Fundo Flex channel element is manufactured from the well-known wedi XPS rigid foam with a closed-cell structure. This material is fully waterproof, load-bearing and lightweight. The channel element is combined with one or more sloping panels that ensure a precise and reliable gradient towards the drain. When used with wedi sealing systems, it forms a completely waterproof shower solution without wet construction processes.
Flexible, low-profile and easy to install
Thanks to its low installation height, the Fundo Flex channel element is ideally suited for bathrooms with limited floor build-up. The element is easy to cut to size and integrates seamlessly with the other components of the Fundo Flex system. This allows for a fast, clear and technically secure installation, even in complex situations.

Part of the complete wedi system
The wedi Fundo Flex channel element forms, together with sloping panels, shower channel, Wave drain and sealing systems, a complete, flexible and technically reliable construction system for waterproof walk-in showers with maximum design freedom.
What is the wedi Fundo Flex?
The wedi Fundo Flex is a modular shower floor system that offers maximum freedom when positioning the shower drain. Unlike standard shower trays with a fixed drain location, the Fundo Flex allows you to determine the drain position yourself. This makes the system particularly suitable for renovations, bespoke solutions and bathrooms with complex floor constructions.
Why choose the Fundo Flex instead of a standard Fundo shower tray?
With standard Fundo shower trays, the drain position is fixed. The wedi Fundo Flex removes this limitation by allowing free positioning of the shower channel. This means existing pipework or floor joists do not need to be altered, and the bathroom design can remain the leading factor. The result is greater technical flexibility and design freedom.
Can the wedi Fundo Flex be used on timber floors?
Yes, the wedi Fundo Flex is suitable for both timber and concrete floor constructions. Thanks to its lightweight, waterproof XPS material and low system build-up height, it is particularly well suited for timber joist floors and renovation projects where structural load and installation height are critical factors.
What is the installation height of the wedi Fundo Flex?
The installation height of the Fundo Flex system is low and depends on the selected components and installation situation. Factors such as the type of slope panels, the chosen Wave drain (DN-40 or DN-50) and the use of a support element all play a role. This flexibility allows the system to be used even where installation height is limited.
Which components are required for a complete Fundo Flex installation?
The wedi Fundo Flex is a modular system consisting of several components. Depending on the installation requirements, the following elements are needed:
wedi Fundo Flex channel element – forms the basis for free positioning of the shower channel
wedi Fundo Flex slope panels – provide a correct and reliable slope towards the drain
wedi Fundo Flex stainless steel shower channel 1.0 – cut-to-length design channel for flexible placement
wedi Wave drain DN-50 or DN-40 – low-maintenance drain with integrated trap
wedi support element for the Wave drain – ensures stable and precise installation without using cement
wedi medium-bed mortar – for bonding the system components
wedi sealing set and slope profiles (optional)
What is the advantage of the wedi support element for the Wave drain?
The wedi support element ensures stable and accurate positioning of the Wave drain. This eliminates the need to build up the drain with cement or mortar, making installation faster and more straightforward. The support element increases installation reliability and contributes to a technically sound and durable drainage solution.
How does the wedi Fundo Flex differ from other walk-in shower systems?
The unique combination of freely positionable drainage, low installation height and a fully waterproof, tested system sets the Fundo Flex apart. It offers maximum design freedom without compromising on technical reliability or waterproofing performance.
Should the wedi Fundo Flex be combined with wedi building boards?
Combining the Fundo Flex with wedi building boards is not mandatory, but it is highly recommended. Wedi building boards provide a stable, waterproof and well-insulated substrate and allow a complete, integrated wedi system to be used throughout the entire shower area.
Is the wedi Fundo Flex easy to maintain?
Yes, the shower channel features a removable cover with an integrated hair catcher, making cleaning easy. The Wave drain is designed for optimal flow performance and ease of maintenance and includes an integrated odour trap.
For which situations is the wedi Fundo Flex most suitable?
The Fundo Flex is ideal for:
Renovation projects where existing pipework or floor joists cannot be relocated
Bathrooms with limited installation height
Designs featuring long or freely positioned shower channels
Timber and concrete floors requiring a lightweight, waterproof solution
Where can I get advice on the wedi Fundo Flex?
