The DOMO single-lever basin mixer is a compact, reliable fixture that combines everyday practicality with engineered detail. Designed for washbasins, it features clean lines, robust brass construction and a premium Chromeline finish. Operation is intuitive: the precise control cartridge L 39 allows smooth, stepless adjustment of flow and temperature; CoolFix supplies cold water in the lever’s mid-position to save energy, and EcoProtect reduces water consumption. Durability is enhanced by ShieldProtect, a membrane that protects internal components from cleaners and deposits, minimizing maintenance. The fixed spout is fitted with a Neoperl® Cascade diffuser (approx. 8 l/min at 3 bar). Flexible 3/8" connection hoses and an M33 x 1.5 threaded tailpiece enable straightforward installation; recommended deck cut-out Ø35 mm. Available in Chromeline, DOMO suits private bathrooms and public washrooms and is ideal for new-builds and renovations with its functional, restrained design.
