New Shower Costs. The actual cost of a new shower depends on your location, the materials used, the complexity of the installation, and other factors. 1  A basic shower enclosure may cost as little as $400 to $600, while a combination bath/shower unit or a top-of-the-line surround could cost $1,500 to $3,000 or more.
A metal with a large number of free flowing electrons most likely has good conductivity
Fun questions! Conductors have many, many mobile electrons. For many metals, it is about one electron per atom which is free to move. These electrons have rather large velocities, due to the fact that they fill up energy levels just as the electrons in atoms fill up available energy levels.
