Concealed Cistern – Bottom Inlet

A concealed cistern with bottom inlet is a compact and efficient flushing solution, designed to be hidden within a WC unit or wall cavity. Ideal for modern bathrooms, it provides a clean, minimalist appearance while maintaining powerful and reliable flushing performance.
