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
Best Answer: Not only do metals have low resistivity, but they are ductile and can be drawn into wires in the first place. Metal wires are strong and flexible, not brittle, and can dissipate heat reasonably well. durability issues might have some merit in explaining this. but the chief reason is that in metal, electrons can travel freely, because there in no gap of electron (band gap) in metal. The two tapes is actually overlapping, therefore no need initial energy to excite the electron to cause flow.
