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
The metal retains a solid structure due to the electrostatic force of attraction between the positive sodium ions and the delocalized electrons. Conductors allow the free flow of electrons through them. Since sodium has electrons that are free to move, it is a conductor of electricity.
