PURPOSE:To set while adjusting a height easily and properly by providing a leg part at a lower end with a cup-shaped pushing member which opens downward and pushing the pushing member on mortar built up in a block on a floor surface to fix the leg part to the floor surface. CONSTITUTION:When a leg part 2 mounted with a pushing member 3 is set on a concrete floor surface 6 on a base stone 7, kneaded mortar 5 is preliminarily built up in a block on the concrete floor surface 6, and then a bath tub 1 is set with the pushing member 3 placed on the mortar 5. Then, the pushing member 3 sinks down into the mortar 5 by the weight of the bath tub 1. At this time, as the pushing member 3 is formed in a cup shape, the pushing member 3 enters the mortar 5 and escape of the mortar toward outward is reduced, and therefore, the sinking down of the pushing member 3 is decreased. Thus, when a setting height of the bath tub 1 is adjusted, if pushing force from the upward is adjusted properly, the sinking down of the pushing member 3 into the mortar 5 can be adjusted properly. Thereby the setting height of the bath tub 1 can be determined by this adjustment. |
