Copper tubs are naturally antibacterial what makes them perfect for slipper soaking tubs. Coppersmiths from Santa Clara del Cobre located in central Mexico have been hammering copper for bathroom for centuries using the same technique. The copper bathtub production process begins with a thick sheeting hammered into a 16 and 14 gauge material use for the production. Since they are handmade, the tubs are truly pieces of art with old European styling. Since each bathtub is individually produced, you as a buyer have liberty to customize it most of the time without any extra cost.
