Geberit Monolith 131.144.SF.1 In-Wall Flushing System, White Glass with Matte Silver Trim — Bathroom Toilets & Toilet Parts
The Geberit Monolith is a different way to solve the same problem a standard in-wall tank solves: hiding the plumbing while keeping the toilet's footprint small. Instead of building out a full wall, the Monolith uses a slim, freestanding glass panel that houses the concealed dual-flush cistern behind a white tempered glass front with matte silver accent trim.
This version is built for floor-standing toilets rather than wall-hung bowls, and the rough-in is adjustable between 9 and 12 inches, which gives installers room to work with an existing floor-mounted toilet's plumbing rather than requiring a full relocation. The dual-flush actuation on the front panel lets users choose a full or reduced flush, which helps cut down on water use over time.
Because the system doesn't require moving the existing rough-in in most cases, it's a practical option for renovations where you want a cleaner, more modern look at the toilet without tearing into the wall. The glass panel finish is easy to wipe down and holds up well in a busy bathroom.
