wedi Fundo Flex Wave Drain DN-40

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.

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.

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.

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.

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)

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.

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.

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.

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.

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
