PROBLEM TO BE SOLVED: To achieve an inexpensive furnishing, improved workability and many kinds of color tones of the bathtub by enabling the curtailing of the number of components, the utilization of conventional parts and light weight parts of the existing unit bath with a separable washing space, by improving workability by integrating several divided parts. SOLUTION: The unit bath comprises a bathtub 1, a general purpose waterproof pan 2 for washing spaces, a small and light linked frame 3, and a small and light closure lid 4A for an opening part adapted to a freely large opening part 3a for working. The link frame 3 is located between one side 1a of a bathtub flange and one side 2a of a washing space flange part and linked onto them with a screw 7a, and a bolt 7b. Thus, the opening part 3a for working is largely opened by removing the closure lid 4A at any time to facilitate working such as inspection and maintenance under the bathtub 1 thereby achieving three-color based selection of parts and improved workability in the assembling of the parts as well.
