(57) A tub (10) comprises a plate (22) having a rim defining a continuous and differentiable curve having no tangential turning points. The plate (22) is formed by one or more wooden boards, the plate (22) defining a top side and a bottom side, the circumferential rim defines a wedge, the wedge defining a circumferential encircling notch at the top side of the plate (22) and/or at the bottom side of the plate (22). The tub (10) further comprises a plurality of oblong wooden elements or wooden staves (20), the elements (20) having a front side and a rear side and defining a top part and a bottom part, each of the elements (20) having a recess in the rear side at the bottom part. The wooden elements (20) are arranged side by side circumferentially encircling the plate (22) and having the wedge of the plate (22) received in the recess of each of the elements (20). A groove is defined within the notch of the plate (22) between opposite walls of the rear side of the elements (20) and a wall of the notch facing the rear side. Still further, the tub (10) comprises two or more bands (12,14,16) of a corrosive resistant material, closely surrounding the wooden elements (20), and an elastic sealing compound sealing the junction between the plate (22) and the wooden elements (20), the sealing compound being received in the groove and adhering to the opposite walls exclusively.
