Built-in shower set kfa² LOGON with 3-function faucet, black — concealed installation

Concealed (built-in) shower set kfa² LOGON with integrated 3-function faucet in a black finish is designed for under-plaster installation. The unit combines a recessed shower mixer body with a trim plate and a three-position diverter, allowing selection between multiple water outlets. The flush-mounted design provides a clean, minimalist aesthetic suitable for modern bathrooms and renovation projects that require a hidden installation.

Advantages

The concealed construction hides the plumbing and leaves only the control plate visible, reducing visual clutter and simplifying bathroom styling. The three-function diverter offers flexible water routing without external valves, enabling easy switching between shower handset, overhead shower or alternative outlet. A black finish provides a contemporary look and coordinates with dark fixtures and fittings while offering corrosion-resistant surface treatment suitable for wet-room environments.

Suitable for

• Residential bathrooms requiring a minimalist, flush-mounted shower solution
• Bathroom renovations where plumbing is set for under-plaster installation
• Showers that need a single concealed control for multiple water outlets

Key specifications

• Installation type: concealed / built-in (under-plaster)
• Control: integrated 3-function diverter for selecting water outlets
• Finish: black, suitable for modern bathroom schemes
• Mounting: trim plate with recessed mixer body designed to be covered by wall finish
• Material characteristics: corrosion-resistant surface treatment for wet environments

How to use

Use the recessed trim plate controls to turn water on and off and to switch between the three available functions. During operation, rotate or press the diverter position according to the product’s ergonomics to select the desired outlet — for example, handset, overhead shower or secondary outlet. Temperature and flow adjustment depend on the connected valve and supply setup; ensure appropriate commissioning and balancing of hot and cold supplies before regular use.

Usage recommendations

Install only with appropriate concealed valve bodies and follow the manufacturer’s installation instructions for under-plaster mounting. Ensure access for service by leaving the recommended maintenance opening or using the specified installation box. Clean the black finish with a soft cloth and mild, non-abrasive cleaner; avoid aggressive chemicals and abrasive pads to preserve surface appearance.
