Wilco is a manufacturer of concealed cistern systems, flush plates and replacement toilet components commonly used in modern bathrooms and apartment developments. Wilco cisterns are designed for wall-hung and concealed toilet installations where the flushing mechanism is hidden inside the wall or joinery cabinetry.

These systems are popular in contemporary bathrooms because they provide a cleaner appearance while saving space and improving hygiene. Wilco concealed cisterns typically use dual-flush technology, allowing toilets to operate using reduced water consumption compared with older flushing systems.

At Sydney Bathroomware we supply a range of Wilco cistern spare parts, including outlet valves, inlet valves and flush components designed to restore proper flushing performance without replacing the entire cistern system
