Definition

This is a steel or metal installation frame designed to be built into a double wall (drywall system) or stud wall. It is used for securely mounting a washbasin (sink), as well as housing the water supply, drain connections, and supporting elements in a concealed manner. The flush-mounted element means that once installed, only the washbasin and the control fittings (e.g., faucet) are visible, while all the pipes, brackets, and the frame remain hidden inside the wall.
