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
i. The drift velocity of electrons in a wire is proportional to the current that flows in the wire. ii. For a material such as copper, which has a high concentration of free electrons, the drift velocity is less than for a material with a lower concentration. iii. If a current flows from a thick copper wire into a thinner copper wire, the electrons will slow down (their drift velocity decreases).
