LAUFEN LIS CW1 Concealed Cistern for Wall-Hung Toilets

The LAUFEN LIS CW1 is a high-quality concealed cistern engineered specifically for wall-hung toilet installations. This in-wall tank system serves as a robust and space-saving solution, allowing for a clean, minimalist bathroom design by hiding the plumbing infrastructure behind the wall. Built with precision, it offers reliable performance and efficient water management for both residential and commercial sanitary environments.

Advantages

The primary benefit of the LAUFEN LIS CW1 is its ability to maximize bathroom space by integrating the flushing mechanism directly into the wall structure. This design not only creates a modern aesthetic but also simplifies floor cleaning by eliminating the need for floor-mounted toilet bases. The system is constructed from durable materials designed to withstand long-term use, ensuring consistent flushing performance and structural integrity within the wall cavity.

Suitable for

• Modern residential bathroom renovations
• Commercial restroom facilities requiring a minimalist look
• Wall-hung toilet installations in tight spaces
• New construction projects focusing on contemporary sanitary design

When it may not be suitable

This concealed cistern is not suitable for floor-mounted toilets or installations where the wall structure cannot support an in-wall tank system. It is also not recommended for DIY projects if the installer lacks professional experience in plumbing and wall construction, as improper installation can lead to leaks or structural issues.

Key specifications

• Designed for wall-hung toilets
• Concealed in-wall installation
• Durable tank construction
• Efficient water management system
• Compatible with standard wall-hung toilet mounting hardware

How to use

The cistern is installed behind a finished wall, typically within a stud frame or a brick wall cavity, before the final wall covering is applied. Once the tank is secured and connected to the water supply and the toilet bowl, the flush plate is installed on the wall surface. Users operate the toilet by pressing the flush plate, which triggers the internal mechanism to release water from the tank into the bowl.

What to consider before purchase

• Ensure your wall structure is deep enough to accommodate the cistern
• Verify compatibility with your chosen wall-hung toilet bowl
• Confirm that the flush plate design matches your bathroom aesthetic
• Check local plumbing codes for concealed cistern requirements

Usage recommendations

Regular maintenance of the flush mechanism is recommended to ensure long-term efficiency. Ensure that the water supply connection is easily accessible via the flush plate opening for any future service needs.
