PROBLEM TO BE SOLVED: To provide an elevating double-bottom floor device of a bathtub which doesn't need adjustment of depth of water when a user enters the bathtub, and which enables a user to enter or get out of the bathtub without anyone's assistance. SOLUTION: A bottom board 2 with holes is attached on the bottom of the bathtub body 1 so that the bottom board can be moved upward/downward, and guide rails 3 and pulleys are attached between the bottom board 2 and the bathtub body 1 to guide the bottom board 2 to move upward/downward. A wire rope 4 is connected to the four square corners of the bottom board 2, and a motor 5 for reeling the wire rope 4 in both directions is set on the ceiling of the bathroom. An operation switch 6 is attached near the main body 1 to turn on/off the motor 5. |
