Proven technology, contemporary design

The Geberit Monolith sanitary module has been recognized with several international awards and is already a hit with designers and homeowners. All the working parts, including tank and fill and flush valves, are hidden inside a sleek metal-and-glass housing, available in wall-hung or floor-standing models.

Designed for ease of installation

Monolith upgrades the look of any bathroom, with minimal effort. The floor-mounted model is designed to replace a standard tank and toilet, attaching to existing supply and waste connections without structural modifications. Installation can be performed by a plumber alone without raising much construction dust or noise. The toilet can be ready to use in just a few hours.

Top marks for water consumption

Every Geberit Monolith sanitary module comes with dual-flush capability built in. Monolith has received top marks on the Water Efficiency Label (WELL label of EUnited Valves).
