PURPOSE: To make a foot washing tub so as not to obstruct the way even if being installed along the side passage of a house by attaching a cover body tiltably to the rear end of a draining floor, and opening a discharge port of a faucet, connected to a feed water pipe arranged in this cover body, to the backside of this cover.

CONSTITUTION: A frame 11 is peripherally installed in the overall circumference of a draining floor 1. Then a hollow plate like cover body 2 is tiltably attached to a rear end of this draining floor 1. Next, almost the whole surface, excepting a top rear end of this draining floor 1, is made so as to be concealed by this cover body 2 in time of closure. At the time of opening, this cover body is held in a state of being uprighted in the rear of this floor 1. Subsequently A feed water pipe 3 is installed in the point midway between both inner and outer walls of the cover body 2. A faucet 4 is connected to the end, opening a discharge port 41 to the backside of this cover body 2. At the time of its closure, this cover body is housed in a cavity part 12 of the draining floor 1. With this constitution, in time of disuse, this cavity part 12 of the draining floor 1 is not exposed to the outside, so such dust as fallen leaves will not be collected, while even if it is installed along the side passage of a house, it will keep out of the way.
