## Long description

The kfa² Otava wall-mounted undercounter washbasin faucet in black, single-handle model 045559-810-81 is a mixer designed for mounting on the wall above a washbasin. It combines a single-lever control for both flow and temperature with a compact spout profile optimized for space-saving configurations and concealed plumbing. The matte or satin black finish integrates with contemporary bathroom interiors and coordinates with other black fittings and accessories.
Advantages
This wall-mounted mixer offers simplified installation for setups with concealed supply lines, freeing up basin deck space and enabling a cleaner visual appearance. The single-handle operation provides intuitive control of water flow and temperature with one motion. A durable black surface finish resists everyday wear and helps maintain a consistent look across the bathroom. The compact spout and wall-mounted layout are suitable for both small and larger basins where deck-mounted installation is not desired.
Suitable for
 Bathrooms with concealed plumbing or in-wall shutoffs
 Wall-mounted undercounter or countertop washbasins where deck space is limited
 Renovation projects seeking a coordinated black-finish faucet set
 Modern and minimalist bathroom designs
Key specifications
 Mounting type: wall-mounted above washbasin
 Operation: single-handle mixer for flow and temperature control
 Finish: black (matte or satin appearance)
 Spout orientation: fixed, directed toward washbasin
 Installation requirement: concealed water supply connections behind wall
 Recommended use: indoor bathroom washbasin installations
How to use
Operate the lever to start and stop the water flow and to set the desired temperature: moving the lever vertically regulates flow rate and horizontally adjusts temperature between cold and hot. Aim the spout toward the washbasin center to avoid splashing. Periodically check the concealed connections for proper sealing after installation and follow local plumbing codes for shutoff valves and service access.
Usage recommendations
For reliable performance, install the faucet with compatible concealed supply fittings and ensure hot and cold lines are correctly oriented. Clean the black finish with a soft, damp cloth and mild detergent; avoid abrasive cleaners or pads that can scratch the surface. If water-saving aeration is desired, verify compatibility with local flow restrictions and replaceable aerator cartridges where applicable.
