PROBLEM TO BE SOLVED: To provide a water-absorbent warmed stone bath structure with a bed on which a number of cobblestones are spread all over and which is warmed on the whole for a user to lie. SOLUTION: The hard porous water-absorbent stone 1 is formed by baking a porous material such as diatomaceous earth as a main material. A large number of porous water-absorbent stones 1 are spread all over the bed 2, and the bed 2 is warmed by a warming means 3 from under the bed. COPYRIGHT: (C)2007,JPO&INPIT
