<p>Claimed is a height-adjustable supporting foot for a bath or shower tub. The foot consists of an upright bolt with head-down and surrounded by a helical spring. The spring is compressed by a cylinder whose closed upper end supports the bath or shower tub. The bolt and spring are located within a cup that is filled with a semi-liquid mass, and the bath is then leveled by weight shift. The semi-liquid mass subsequently cures into a hard block.</p> |
