The safe solution for showering on timber floors
With the wedi Fundo Ligno Plus, you choose a technically advanced shower element that has been specifically engineered for timber floor constructions. Combine it with a wedi waste, sealing systems and optionally wedi Fundo Top to create a durable, fully waterproof and low-maintenance walk-in shower.
wedi Fundo Ligno Plus – the ultra-thin shower tray for timber floor constructions
The wedi Fundo Ligno Plus is a prefabricated walk-in shower tray developed specifically for bathrooms with timber joist floors and wooden suspended floors. Thanks to its minimal edge height of just 23 mm, the tray can be fully integrated into the load-bearing timber floor layer. This makes it ideal for both renovation of older buildings and modern new-build projects with timber floor structures.
Designed for timber floors – safe and technically reliable
Installing a walk-in shower on a timber floor requires maximum reliability. The Fundo Ligno Plus is engineered precisely for this application. Its flush integration prevents unwanted height differences while providing a stable, fully waterproof base for tiles or an alternative seamless finish with wedi Fundo Top.
- Ideal for timber joist and wooden suspended floors
- Only 23 mm edge height for seamless integration
- Compatible with renovation and new-build projects
- Stable and load-bearing shower base
Prefabricated slope and 100% waterproof core
Like all wedi Fundo shower trays, the Ligno Plus features a factory-formed slope that ensures reliable drainage towards the waste outlet. The core is made from closed-cell extruded polystyrene (XPS), which is completely waterproof and does not absorb moisture. The surface is finished with a robust, fibre-reinforced mortar layer and is ready for tiling immediately.
Flexible waste selection to suit your installation
The wedi Fundo Ligno Plus is supplied without a fixed waste, allowing you to select the most suitable wedi waste for your project. In most cases, a DN-50 horizontal or vertical waste is used. Where installation height is limited, a DN-40 waste may also be applied. Waste position can be central or offset, depending on the chosen size and floor structure.
- Waste not included – ordered separately
- Suitable for DN-50 horizontal or vertical wastes
- DN-40 possible for minimal build-up height
- Central or offset waste position available
Fast and secure installation on timber subfloors
The Fundo Ligno Plus is lightweight and easy to handle. It can be cut to size on site while maintaining its geometry and slope. Combined with wedi sealing systems, it forms a durable and fully waterproof walk-in shower solution that meets the demands of timber floor constructions.
- Prefabricated shower tray – no wet screed required
- Ready for tiling immediately
- Suitable for residential and professional use
- Fully compatible with wedi building boards and wall systems
Design freedom with waste covers and wedi Fundo Top
For the final finish, the Fundo Ligno Plus can be combined with a wide range of wedi waste covers. It is also compatible with wedi Fundo Top, a ready-made seamless surface that replaces tiles and creates a modern, low-maintenance shower area without grout joints.
