Concealed Solution for Limited Installation Depth

July 29, 2025

In modern bathroom design, every centimetre matters – especially when the depth of the wall is limited. That’s exactly where the LIV-FIX WC 9052 comes into play: our slimmest concealed cistern, specifically designed for spaces where standard solutions are not suitable.

Whether it’s the renovation of older buildings, narrow partition walls or sanitary units in public facilities – this model delivers maximum functionality in minimal space.

Why LIV-FIX WC 9052?

Extremely small installation depth
With an adjustable range of 91 to 140 mm, this model is the ideal solution for shallow drywall constructions or narrow masonry niches. The exact depth depends on the specific installation situation and the project requirements – such as pipe alignment, wall flush mounting, or adapting to existing structures. The depth is typically defined by the planner or installer based on the real-life scenario.

Wide Selection of Flushing Plates

In bathroom design, it’s often the details that make the difference – and the flushing plate is one of the key visual elements. The LIV-FIX WC 9052 is compatible with a wide range of flushing plates that offer both functional and aesthetic flexibility.

Ruby, Caro, Zircon, Circle – soft and geometric shapes,
Beat, Key, Tune – contemporary and minimalist designs,

You can choose between various materials and finishes – from minimalistic gloss to brushed metal textures.
