Wiesbaden One-Pack concealed thermostatic mixer set round type 403 in gunmetal

The Wiesbaden One-Pack concealed thermostatic mixer set type 403 is a concealed thermostatic mixer set in gunmetal with a round design, supplied in the 30 cm version. This larger variant is ideal for those who want to make more of a statement in the shower enclosure. As a One-Pack, everything comes in a single package, ensuring a consistent finish throughout. The dark gunmetal tone adds a warm, industrial accent to the bathroom.

Generous sizing: The 30 cm variant is larger than the 20 cm version from the same range and gives the shower enclosure greater presence.

Easy to order: With a One-Pack, there is no need to compare individual components — the combination has already been put together for you.

Round design: The rounded lines complement round basins and mirrors beautifully, creating a soft, cohesive overall impression.

Thermostatic comfort: The set temperature remains stable, making showering comfortable and safe for the whole family.

Gunmetal finish: This dark metallic colour is less stark than matt black and pairs well with natural materials.
