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
Gold is the most 'noble' metal resulting from a very stable electronic structure. In any solid metal there is a tendency for electrons in the outermost atomic orbitals to 'float' between atoms, like a sort of electronic atmosphere. This atmosphere can be blown along by the potential electric difference (volts) between one point and another and is what creates an electric current.
