A paraffin bath apparatus for melting paraffin used in therapeutic applications is disclosed. The paraffin bath apparatus comprises a housing having a base, a sidewall and upper opening. An inner tub is formed of a temperature resistant polymeric material is a generally cup shaped member having a bottom wall, an upstanding wall and an open top. The inner tub is received within the upper opening of the housing with the bottom wall of the inner tub overlying the base of the housing. The heating element is located between the inner tub and the housing for providing heat to the inner tub sufficient to melt the paraffin but below the temperature that would adversely affect the polymeric material forming inner tub. A thermostatic sensor is disposed between the inner tub and the housing and is electrically connected to the heating element to control the heat provided to the inner tub. A temperature indicating element may be provided in the inner tub and placed in contact with paraffin melted in the inner tub. The temperature indicating element provides a visual indication that the paraffin in the tub is within a predetermined temperature range and is visible through the melted paraffin.
