Abstract: The invention includes a method and apparatus for quieting and insulating a bath during its operation in order to reduce the amount of noise and vibration transmitted to its user. The bath comprises a bath vessel and a pre-molded high density insulation pad secured thereto for insulating the bath vessel from noise, vibration and heat transfer. The pre-molded insulation pad is positioned on the bottom of the bath vessel while the laminate of the bath vessel is still wet so that the pad bonds with the bath vessel as the laminate cures. After the pre-molded insulation pad has bonded to the bath vessel, an upper surface of the bath vessel is leveled with a lower surface of the pre-molded pad so that these upper and lower surfaces are parallel to each other. Further, the pump assembly is positioned away from the bath vessel during installation and operation so that vibrations generated by its pump are not directly transmitted from the pump assembly to the bath vessel.
