The wedi Fundo Flex sloping panel with rebate is part of the modular Fundo Flex system and forms the basis for a modern walk-in shower with a linear drain. This sloping panel offers maximum flexibility when determining the drain position and can easily be adapted to almost any bathroom layout. Thanks to its low installation height and waterproof XPS construction, this element is suitable for both new builds and renovation projects.
When do you use this sloping panel?
This sloping panel is available in different thicknesses and is used in combination with the wedi Fundo Flex channel element. The version with rebate is designed for installation on top of the floor structure, where the rebate ensures a clean and secure connection to the channel element.

wedi Fundo Flex – a flexible system solution for shower floors with linear drains
The wedi Fundo Flex is a modular shower floor system that offers maximum design freedom for walk-in showers with a linear drain. Unlike standard shower floors with a fixed drain position, the Fundo Flex allows the drain to be positioned exactly where the design or existing installation requires it. This makes the system particularly suitable for renovations, bespoke solutions and bathrooms with limited installation height.
Maximum freedom in drain positioning
With many shower floors, the drain position is predetermined, which can result in unwanted adjustments to the floor structure or pipework. The wedi Fundo Flex removes this limitation. Thanks to its modular design, the drain can be positioned freely: directly against the wall, at a distance from the wall, or even centrally within the shower area. This allows the system to integrate perfectly with modern bathroom designs and technical constraints.

Part of the complete wedi system
The wedi Fundo Flex sloping panel with rebate, together with the channel element, Wave drain, sealing systems and optionally wedi Fundo Top, forms a complete, flexible and technically reliable building system for modern, fully waterproof walk-in showers.
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
