PROBLEM TO BE SOLVED: To fasten the lower edge of a bathtub apron to the bank of a waterproof pan efficiently, making the width of the flange at the bottom of the apron narrow. SOLUTION: A protrusion 62 is formed on the top of a bank 16 located in the borderline between a bathtub setting part and the washing area 14 of a waterproof pan 10, and a fixing member 44 is attached to a flange 32 at the lower edge of a bathtub apron 22. The fixing member 44 is a separate body from the apron 22 and has a spring elasticity in the vertical direction. The fixing member 44 has a notch 54 to be engaged with the protrusion 62 from the washing area 14 side for prescribing the quantity of pushing the apron 22 toward the bathtub side, and hook nails 55 to be hooked on the edge 64 of the bank 16 on the bathtub side for preventing the apron 22 from being detached toward the washing area 14 side.
