The Sourcing THEMA LUX DF12304-1 Black single-lever shower mixer is a wall-mounted shower faucet designed to control water flow and temperature with a single ergonomic handle. Finished in matte or satin black, the mixer provides a compact footprint that fits contemporary bathroom interiors and standard shower installations where a combined control valve is required. The unit integrates a smooth rotational control for precise temperature adjustment and a lever action for immediate flow regulation.

Advantages

This single-lever shower mixer combines compact design and straightforward operation to simplify daily shower use.

The wall-mounted format leaves the shower area uncluttered and allows for easier cleaning around the fixture.

How to use

Operate the lever to start or stop water flow and rotate or tilt it to adjust temperature as required.
