## Summary description

## Long description

The kfa² LOGON BLACK bidet faucet (concealed/mounted bidet mixer) is a black-finish fitting designed for personal hygiene installations that require either a built-in valve body or surface-mounted connection. The mixer provides a minimalist appearance with a matte black aesthetic intended to match contemporary bathroom designs. It is intended for use on bidets where a discreet, corrosion-resistant black tap is preferred.
Advantages
The concealed/mounted design allows flexible installation in installations with hidden plumbing or with a visible mounting box. The black finish is resistant to typical bathroom wear and creates a uniform look with other black sanitary fittings. The mixer delivers controlled water flow and temperature through a single control mechanism, simplifying operation while maintaining precise adjustment. The design reduces visible plumbing lines and supports a clean, modern bathroom layout.
Suitable for
Residential bathrooms where a black, low-profile bidet fitting is desired
Public washrooms that require durable, easy-to-maintain bidet fixtures
Renovation projects that use concealed valve bodies or surface-mounted mixers
Contemporary or minimalist interior schemes emphasizing matte black fixtures
Key specifications
Installation type: concealed or mounted (compatible with built-in or surface-mounted valve bodies)
Finish: black, suitable for modern bathroom color schemes
Function: single-mixer bidet faucet for personal hygiene
Operation: single control for flow and temperature regulation
Application: bidet mounting on bathroom fixtures with appropriate valve configuration
How to use
Install the bidet mixer according to the installer’s instructions for concealed or surface-mounted valve bodies, ensuring water supply lines are shut off before connection. After mechanical mounting and water connections are completed and checked for leaks, use the single control to regulate water flow and set a comfortable temperature. Operate the control smoothly to avoid sudden temperature changes and verify proper drain function of the bidet fixture during first use.
Usage recommendations
To preserve the black finish, clean the surface with a soft cloth and mild, non-abrasive detergent; avoid strong acids, alkalis, or abrasive pads. Periodically check connections for leaks and service the cartridge or seals according to standard sanitary hardware maintenance intervals. For installations in hard-water areas, consider routine maintenance to prevent mineral buildup affecting flow and operation.
