<P>PROBLEM TO BE SOLVED: To provide a wood bath or a stone bath which can be placed without the time and effort in a bathtub for business and has a strong thermal effect and strong energy-saving effect. <P>SOLUTION: A bathtub considered is a unit type which is used for a household. Heat insulating effect is enhanced by creating a double structure and making an air layer while using FRP with a strong heat insulating effect for base material. Since the temperature of bathtub water decreases slowly by enhancing the heat insulating effect, energy associated with reboiling the bathtub water can be saved. If a plate material to be attached to a surface is made out of stone, the bathtub can give a stone bath look. When a wooden board is attached on the base, the bathtub can give a wood bath look. <P>COPYRIGHT: (C)2010,JPO&INPIT |
