The Superflat bathroom drain is a floor-level drain that requires little space but delivers maximum performance. With a minimum installation depth of just 95 mm, it is specifically designed for renovating existing buildings where floor build-up is restricted. Despite its compact size, the drain combines tasteful design covers with a high drainage capacity of up to 0.9 l/s, and features flexible nozzles with acoustic decoupling for quiet operation.
The drain has a DN 50 outlet and is available in two versions: one inlet or three inlets. The removable odour trap uses a "Lock & Lift" system for effortless maintenance, and optional waterless Multistop protection provides rodent, foam, and odour stop functionality. The Variofix upper section is rotatable, tiltable, and height-adjustable to accommodate different installation scenarios. A safe-to-install sealing system with a lip seal firmly connected to the drain body ensures a reliable water-tight installation. The product is suitable for barrier-free construction in both renovation and new building projects.
