  • As far as hot tubs and sanitation are concerned, the numbers are what matters. To kill bacteria, a hot tub must contain a sanitizer, such as chlorine or bromine. Effective bacteria elimination requires no less than a free chlorine or bromine residual of 1.0 parts per million. A pH between 7.2 and 7.8 is also necessary for the sanitizer to be effective. A water test will provide information on both the free residual and pH levels. A bacteria sample taken with each test will show whether the sanitizer is performing optimally. A negative bacteria result reflects a well-sanitized hot tub.

    The lacquer according to the present invention is based on epoxy resin, particularly baking enamels. According to a preferred embodiment of the invention, a water-dilutable epoxy resin lacquer applied by electro-immersion painting is used. A thin film between 10 and 40 μm with a high solids content can be applied by electro-immersion lacquering. After rinsing off the film of lacquer with ultra-filtrated water, the film of lacquer receives its final hardness and strength at a baking temperature between 150 and 200° C. The coating with an epoxy resin lacquer is characterized by excellent adhesive strength, high hardness, as well as high resistance to abrasion. Furthermore, it has surprisingly favorable primer properties, and it effects a solid bond with the intermediate layer, which consists of a polyurethane or methacrylic compound. The result is a sanitary tub with a strong bond between the metallic outer shell and the plastic inner shell.

  • In addition, the invention discloses the method of manufacturing the sanitary tub having an inner and outer shell. An intermediate layer is applied between the inner shell and the outer shell. A protective coating is then applied to an inner and outer side of the outer shell. The protective coating comprises a conversion layer produced by phosphatizing, and a lacquer forming an abrasion and impact resistant layer on the outer side, and an adhesive agent on the inner side between the outer shell and the intermediate layer without roughening.

    Facilities that provide hot tubs for public use require regular health inspections to determine their sanitation levels. If you have concerns, put your mind at ease and ask the facility director for information about the hot tub, such as how many people use it per day, how often inspections take place and the qualifications of the employees that care for the hot tub. Ask how often the employees check the pH and chlorine levels. A sanitary hot tub has a pH and chlorine check two times a day, every day, according to the Centers for Disease Control and Prevention.

  • An object of the present invention is to provide a sanitary tub having the structure described above, without damaging the corrosion protection on the outer shell and the connection between the outer and inner shells during production.

Sanitary tubs are known from DE-C 44 31 716, in which the outer shell is pickled and basically enameled on the back side. Since the adhesion of the intermediate layer consisting of a polyurethane or a methacrylic compound is inadequate on an enameled surface, no enameling is provided on the inner surface of the steel sheet shell. This makes manufacturing of the tub more difficult because a commonly used immersion process cannot be applied for the enamel coating. The coating of enamel applied to the inner side has to be mechanically removed, for example by sandblasting, or at least have the surface roughened. According to another design described in DE-C 44 31 716, the outer shell, which is deep-drawn from steel sheet, is pickled and passivated before the acrylic shell is molded on the inner side and glued to the steel blank. In a last process step, the rust-preventing coating is applied to the outer shell of the composite tub. In this step, the ledge and the inner side of the composite tub, which is already manufactured, have to be covered by a costly process. Furthermore, there is the risk that the protection against corrosion may be incomplete along the ledge of the tub because of the required coverings.
