Geberit’s Monolith, as detailed in this brochure, has a modular structure made of high-quality materials, such as safety glass and brushed metal, and is available in black or white. The toilet tank, as well as the fill and flush valves, are hidden inside a sleek, brushed-metal housing. It fits the same rough-in as a standard toilet and uses a dual-flush mechanism (1.6 gal. per flush and 0.8 gpf) that is built into the top of the housing. The Monolith was developed to connect to existing drainage and water supply connections.
