The wedi Complete Underfloor Heating Kit for Bathrooms is a carefully assembled all-in-one solution for a comfortable and fully waterproof bathroom floor. This system is based on the pre-grooved wedi boards for 16 mm underfloor heating pipes with a centre distance of 12 cm. All required materials are matched to the selected area of 4 m² or 6 m², ensuring you immediately have the correct quantities for an efficient installation.
Unlike traditional systems, this solution uses a dry-build construction with no waiting time or drying process. The waterproof wedi boards, combined with the included components, form one technically integrated floor system, ready for tiling and connection up to the manifold or RTL valve.
➕ Complete kit designed for 4 m² or 6 m²
➕ Choice of 30, 40 or 50 mm board thickness
➕ Suitable for 16 mm PE-RT pipes (120 mm centres)
➕ Includes pipes, washers, edge insulation, screws and reinforcing tape
➕ Includes primer and tile adhesive
➕ Kits can be combined for larger areas (e.g. 4 + 6 m²)
➕ Manifold or RTL valve available as an optional add-on
With the wedi Complete Underfloor Heating Kit for Bathrooms you choose certainty, speed and comfort. All materials are precisely matched to your floor surface area, so you do not need to calculate quantities and will not end up with shortages or excess materials. Order the correct kit directly or combine multiple sets for larger spaces and create a professional, waterproof underfloor heating system.
The wedi Complete Underfloor Heating Kit for Bathrooms is a carefully assembled dry-build system designed to create a comfortable and fully waterproof bathroom floor. The kit is based on pre-grooved wedi boards for 16 mm PE-RT underfloor heating pipes with a centre distance of 12 cm. All components are precisely matched to the selected floor area of 4 m² or 6 m², ensuring you immediately have the correct quantities for an efficient and professional installation.
Unlike traditional underfloor heating installed in cement screeds, this system uses a dry-build construction without drying time. The combination of waterproof wedi boards, high-quality fixing materials and coordinated accessories creates a stable and durable floor construction that is immediately ready for tiling.
The complete kits are available in three board thicknesses: 30, 40 and 50 mm. This allows the floor construction to be perfectly matched to the existing situation or to the thickness of a wedi Fundo shower tray. The result is one continuous, fully waterproof bathroom floor with integrated underfloor heating.
Do you have a floor area larger than 4 m² or 6 m²? Simply combine multiple kits, for example 4 + 4 m² or 4 + 6 m². This allows you to scale the system easily without complex calculations.
Each kit contains all materials required to install the floor system up to the tile layer and up to the connection to the manifold or RTL valve. The contents are matched to the selected floor area.
A manifold or RTL valve is not included as standard but can easily be supplied as an additional option.
Thanks to this dry and well-designed construction, a stable, insulating and fully waterproof floor structure is created that heats up quickly and is ready for use immediately.

The complete kit includes the pre-grooved wedi boards as well as all required materials such as 16 mm PE-RT pipe, washers, edge insulation, screws, reinforcing tape, primer and tile adhesive. All quantities are precisely matched to 4 m² or 6 m², so you do not need to calculate materials and you avoid leftover waste.
Yes. The wedi boards are 100% waterproof by themselves. In combination with wedi 610 and reinforcing tape, you create a fully waterproof floor construction suitable for bathrooms and other wet rooms.
This complete kit is suitable for 16 mm PE-RT underfloor heating pipes with a centre distance of 12 cm. This fixed spacing ensures even heat distribution.
Yes. If you need, for example, 8 m² or 10 m², you can easily combine multiple sets, such as 2 × 4 m² or 4 + 6 m². This allows you to scale the system flexibly without complex calculations.
No. A manifold or RTL valve is not included as standard in the kit. These can be ordered separately, depending on the required connection and installation set-up.
A manifold is used when the underfloor heating is part of a larger system with multiple circuits or when you want central temperature control. An RTL valve is often used for smaller areas, such as a bathroom, connected to an existing central heating system without a separate circuit. The most suitable option depends on the situation and the type of control you want.
Yes. This system can form part of an existing underfloor heating installation. Depending on the build-up and capacity, it can be connected to an existing manifold or expanded with an additional circuit. This makes it easy to integrate the bathroom into the overall heating system.
Yes. For wooden subfloors, a suitable primer is applied first, such as Ardex P52. The wedi boards are bonded and additionally mechanically fixed with screws and washers for maximum stability.
No. This is a dry-build system. No cement screed needs to be poured, so there is no long drying time. After installation and bonding, the floor can immediately be prepared for tiling.
Yes. The wedi boards are made from XPS rigid foam and have insulating properties. This ensures heat is efficiently directed upwards while reducing heat loss to the underlying structure.
Certainly. The system is suitable for any area where tiles are installed, such as kitchens, utility rooms, entrance areas and wellness spaces. Thanks to its waterproof and insulating properties, it can be used in a wide range of applications.
Yes. The system can be controlled with a suitable thermostat, including Wi-Fi or smart controls. The exact options depend on the chosen manifold or RTL valve and the central heating system. Ask about the best solution for your situation.
Yes. Thanks to its low build-up height, light weight and dry installation method, this underfloor heating system is highly suitable for bathroom renovation projects.
Yes. Underfloor heating in combination with wedi is specialist work. Advice is available remotely or in the showroom, so you can be confident you have the correct build-up and material selection.
