Abstract: The shower structure comprises a base for containing water, two panels and a two-part elongated joint. The base comprises a doorstep, a base edge and a bottom. The base edge has an inner portion lower than upper surface of the doorstep. Each panel has a first panel edge provided with an inner portion for contact with the inner portion of the base edge for fitting the base and the panel in a watertight manner, a second panel edge also provided with an inner portion. The joint includes an outer part having, along its length, two distal joint edges. Each joint edge is adapted for connection to the inner portion of the second panel edge for fitting the panel and the outer part of the joint together. An inner part of the joint is connected to the outer part for sealing the base and panels together in a watertight manner.
